Genascence Announces Data From Phase 1 Clinical Trial on GNSC-001, Company’s Lead Program in Osteoarthritis, Presented at American Society of Gene…
Posted: at 7:15 pm
PALO ALTO, Calif., May 17, 2022 /PRNewswire/ --Genascence Corporation ("Genascence"), a clinical-stage biotechnology company revolutionizing the treatment of prevalent musculoskeletal diseases with gene therapy, today announced that additional safety data from the Phase 1 clinical trial of GNSC-001 for the treatment of osteoarthritis (OA), including 12-month follow-up on all subjects, demonstrated that it was safe and well tolerated. These data will be delivered in a poster presentation today at theAmerican Society of Gene& Cell Therapy's(ASGCT) 25th Annual Meeting being held virtually and in-person May 16-19, 2022, in Washington, D.C.
GNSC-001 is the company's lead program in OA. GNSC-001 is a genetic medicine a recombinant adeno-associated vector (AAV) carrying a coding sequence for interleukin-1 receptor antagonist (IL-1Ra), a potent inhibitor of interleukin-1 (IL-1) signaling. IL-1 is considered one of the key mediators involved in the pathogenesis of OA, causing inflammation as well as cartilage destruction. GNSC-001 is designed to offer long-term, sustained inhibition of IL-1 following a single injection into the affected joint.
"Osteoarthritis is incapacitating, causing years of pain and disability for people living with the disease. Further, patients have limited treatment options, and nothing is currently available that is able to slow down progression of OA," said Thomas Chalberg, Ph.D., founder and CEO of Genascence. "We are excited by these findings as they demonstrate the initial safety of GNSC-001 and provide encouraging data to pursue GNSC-001 as a novel treatment for OA patients. We look forward to advancing the clinical program for GNSC-001 so that we can deliver transformative results for patients suffering from this disabling disease."
Title:A Phase I Trial of Osteoarthritis Gene Therapy (NCT02790723)Date:May 17, 2022 5:30-6:30 PM ETSession: Gene and Cell Therapy Trials in ProgressAbstract Number: 799Location: Walter E. Washington Convention Center, Hall DPresenter: Christopher H. Evans, Ph.D.
In this investigator-sponsored Phase 1 single-arm, open-label, dose-escalation clinical trial of GNSC-001, a total of nine subjects with knee OA were enrolled and monitored for one year. Three subjects were treated in each of three cohorts, receiving either 1x1011 vg, 1x1012 vg, or 1x1013 vg GNSC-001 delivered by intra-articular injection. The primary endpoint is safety and tolerability. Additional measures include levels of circulating viral genomes, immune response to the vector, blood and urine analysis, and physical examination. Although the study was not powered for efficacy and had no control group, patients reported pain via VAS (0-10) and pain and function via WOMAC. Knee joints were imaged by X-ray and MRI upon study entry and after one year.
Results showed that intra-articular injection of GNSC-001 produced no severe adverse events; blood chemistries and hematologies remained normal during the 12-month follow-up period with no evidence of neutropenia. There were no vector-related adverse events in eight of the nine subjects; one subject experienced a mild/moderate knee effusion following injection which resolved with ice and rest. Clinical trial participants developed various degrees of anti-AAV neutralizing antibodies after injection of GNSC-001, as seen in preclinical studies. Small amounts of viral genomes were found in peripheral blood, beginning one day after injection and clearing within four weeks. Injection of GNSC-001 was associated with increased concentrations of IL-1Ra in synovial fluid, which remained elevated after 12 months of follow up. Pain and function scores improved following injection of GNSC-001.
"These additional data from the Phase 1 trial of GNSC-001 in patients with osteoarthritis showed that it safe and well tolerated including after one year," said Dr. Evans. "These results are encouraging as we believe this therapy has the potential to reduce structural disease progression in osteoarthritis patients."
The study was supported by funding from the U.S. Department of Defense Peer Reviewed Medical Research Program (PRMRP). More information is available at https://clinicaltrials.gov/ct2/show/NCT02790723.

About Osteoarthritis (OA) of the Knee
Osteoarthritis (OA), or degenerative joint disease, is the leading cause of disability. It is characterized by destruction of cartilage and structural changes in bone within the joint, which contribute to pain and loss of joint function. Osteoarthritis affects more than 30 million Americans and is increasing as a result of the aging population and increasing prevalence of obesity. Osteoarthritis represents a major economic burden, owing to direct medical costs and loss of productivity. Each year, millions of patients are treated for knee OA with NSAIDs, opioids, and steroid injections into the knee to manage their knee pain. There are no currently available therapies known to alter or slow down OA progression.

Will we be able to check cholesterol using gene editing technology or will it be too dangerous and costly to even try? – L’Observateur – L’Observateur
Posted: at 7:15 pm
WASHINGTON, DC The covid virus killed some 460,000 Americanslast year, heart disease killednearly 700,000people in the U.S. in the same period.The fact is that heart attacks are the number one cause of death in America and throughout the world.So, the announcement that scientists are testing a way to prevent heart attacks with a single injection may sound like a life-saving game-changer, particularly for seniors over the age of 65 who, according to the National Institute on Aging, are much more likely than younger people to suffer aheart attack.
Verve Therapeutics describes itself as a biotechnology company created with a singular focus: to protect the world from heart disease.Over the next three years the company says it will be testing a radical gene therapy to permanently prevent the buildup of bad cholesterol with that single injection.Cardiologist, geneticist and CEO of Verve Therapeutics, Dr. Sekar Kathiresan, says The therapy will be relevant, we think, to any adult at risk of a heart attack.We want this not only for people who have heart attacks at a young age because of a genetic disorder, but for garden variety heart attacks as well.
Kathiresan resigned positions at Harvard Medical Schooland the Center for Genomic Medicine at Massachusetts general hospital to create Verve Technologies.We really think we can turn the tide against coronary disease by moving from a chronic care model to [eradication with] a one-time treatment, he toldThe Guardian.Currently, blood thinners, statins to lower cholesterol levels and high blood pressure medications are the standard treatments for individuals with a risk of heart disease.But seniors in particular can be overwhelmed by the treatments and may stop complying with their doctors orders.Or they may simply forget to take their meds.
Phase one of field tests of Verves procedure showed promise, according to aBloomberg report.Monkeys were treated and within six months their cholesterol levels were reduced by 59%.It will be months before human testing will begin and years before Verve might have sufficient proof that the process is safe and that it works in order to seek government approval of its use.
Ultimately, says Bloomberg, the company will face plenty of hurdles in its attempt to treat the masses.Its one of the firsttestsof using Crispr [a gene editing tool] to edit DNAinside the human body, and patients and doctors could be wary of making a permanent change without knowing much about long-term safety, saysElizabeth McNally, director of the Center for Genetic Medicine at the Northwestern University Feinberg School of Medicine.McNally also pointed out that the reluctance to take Covid-19 vaccines suggests some people may be loath to alter their DNA.
And then there is the matter of cost.Effective cholesterol medications are available for as little as nine dollars a month while Verves therapy will cost from $50,000 to $200,000 per patient, according to Bloomberg.

Ultragenyx Acquires Global Rights to AAV Gene Therapy ABO-102 for Sanfilippo Syndrome Type A (MPS IIIA) from Abeona Therapeutics – GlobeNewswire
Posted: at 7:15 pm
ABO-102 / UX111 is being evaluated in ongoing pivotal Transpher A trial in patients with MPS IIIA
Interim data featured in encore oral presentation at American Society of Gene & Cell Therapy (ASGCT) today
NOVATO, Calif. and NEW YORK and CLEVELAND, May 17, 2022 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE) and Abeona Therapeutics Inc. (Nasdaq: ABEO) today announced an exclusive license agreement for AAV gene therapy ABO-102 (now UX111) for the treatment of Sanfilippo syndrome type A (MPS IIIA). Under the terms of the agreement, Ultragenyx will assume responsibility for the ABO-102 program and in return Abeona is eligible to receive tiered royalties of up to 10% on net sales and commercial milestone payments following regulatory approval.
Based on promising data from Abeonas clinical program, regulatory feedback to date, and our experience developing treatments for other MPS diseases, we believe ABO-102 has the potential to be a transformative therapy for patients with MPS IIIA, said Emil D. Kakkis, M.D., Ph.D., Chief Executive Officer and President of Ultragenyx.Our teams expertise in MPS and gene therapy clinical development makes this program a seamless integration, and it has the potential to be our first gene therapy to market. The Sanfilippo community has been waiting too long for a first treatment and we believe we can help accelerate this program.
Data from the ongoing Transpher A trial demonstrate ABO-102 holds significant potential to improve outcomes for patients with MPS IIIA who experience relentlessly progressing neurodevelopmental and physical decline that is life-threatening at a very young age, said Vish Seshadri, Ph.D., Chief Executive Officer of Abeona. We believe that Ultragenyx, with deep expertise in rare, genetic, metabolic lysosomal storage disorders and a demonstrated commitment towards MPS diseases, is the ideal partner to eventually bring ABO-102 to patients.
Abeona has completed a successful Type B meeting with the U.S. Food and Drug Administration (FDA) regarding the pivotal Transpher A trial to support filing and approval for ABO-102 for the treatment of patients with MPS IIIA. Interim results from the Transpher A trial presented in an encore presentation at the American Society of Gene & Cell Therapy (ASGCT) today demonstrate that neurocognitive development was preserved in children treated before 2 years old or with a development quotient (DQ) > 60 (n=10) within normal range of a non-afflicted child after treatment with ABO-102 (3x1013 vg/kg). The interim results also showed continued or stabilized cognitive function and behavioral progress using standard developmental assessments. Some of these patients have reached 24-months post treatment and stabilization or increase in cortical gray matter, total cerebral, and amygdala volumes have been observed. Statistically significant reduction in liver volume was seen with ABO-102 treatment. Dose-dependent and statistically significant reductions in cerebrospinal fluid and plasma heparan sulfate, demonstrating replacement of enzyme activity consistent with levels required for disease correction in the central nervous system, have been sustained in treated patients for two years after treatment. ABO-102 has been well-tolerated with no treatment-related serious adverse events and no clinically meaningful adverse events reported.
MPS IIIA is characterized by severe neurodegeneration with debilitating symptoms for which there is currently no treatment, said Kevin Flanigan, M.D., director of the Center for Gene Therapy at Nationwide Childrens Hospital in Columbus, Ohio, and Transpher A study principal investigator. The promising results to date suggest a single intravenous dose of ABO-102 AAV-based gene therapy has the potential to help children with MPS IIIA sustain neurocognitive development when they are treated during early stages of their disease.
About ABO-102 / UX111ABO-102 (now UX111), is a novel gene therapy in Phase 1/2 development for Sanfilippo syndrome type A (MPS IIIA), a rare lysosomal storage disease with no approved treatment that primarily affects the central nervous system (CNS). ABO-102 is dosed in a one-time intravenous infusion using a self-complementary AAV9 vector to deliver a functional copy of the SGSH gene to cells of the CNS and peripheral organs. The therapy is designed to address the underlying SGSH enzyme deficiency responsible for abnormal accumulation of glycosaminoglycans in the brain and throughout the body that results in progressive cell damage and neurodevelopmental and physical decline. The ABO-102 program has received Regenerative Medicine Advanced Therapy, Fast Track, Rare Pediatric Disease, and Orphan Drug designations in the U.S., and PRIME and Orphan medicinal product designations in the EU.
About the Transpher A StudyThe Transpher A Study (ABT-001) is an ongoing, two-year, open-label, dose-escalation, Phase 1/2 global clinical trial assessing ABO-102 for the treatment of patients with Sanfilippo syndrome type A (MPS IIIA). The study is intended for patients from birth to 2 years of age, or patients older than 2 years with a cognitive developmental quotient of 60% or above. ABO-102 gene therapy is delivered using AAV9 technology via a single-dose intravenous infusion. The study primary endpoints are neurodevelopment and safety, with secondary endpoints including behavior evaluations, quality of life, enzyme activity in cerebrospinal fluid (CSF) and plasma, heparan sulfate levels in CSF, plasma and urine, and brain and liver volume.
Further details can be referenced here: https://clinicaltrials.gov/ct2/show/NCT02716246
About Sanfilippo syndrome type A (MPS IIIA)Sanfilippo syndrome type A (MPS IIIA) is a rare, fatal lysosomal storage disease with no approved treatment that primarily affects the CNS and is characterized by rapid neurodevelopmental and physical decline, often by age three. MPS IIIA has a global incidence of one in 100,000 with a median life expectancy of 15 years.
Children with MPS IIIA present with progressive language and cognitive decline and behavioral abnormalities. Other symptoms include sleep problems and frequent ear infections. Additionally, distinctive facial features with thick eyebrows or a unibrow, full lips and excessive body hair for ones age, and liver/spleen enlargement are also present in early childhood. MPS IIIA is caused by genetic mutations that lead to a deficiency in the SGSH enzyme responsible for breaking down glycosaminoglycans, which accumulate in cells throughout the body resulting in rapid health decline associated with the disorder.

This Gene Mutation Breaks the Immune System. Why Has It Survived? – WIRED
Posted: at 7:15 pm
In Greenland in January 2021, a child just under two years old was sickvery sick. And his doctors couldnt figure out why. He was feverish, vomiting, having seizures. Meningitis was suspected to be the cause; a tuberculosis diagnosis was also being tossed around. The child was transferred to Copenhagento Rigshospitalet, the largest hospital in Denmarkfor further evaluation.
By March, the childs doctors were no closer to figuring out why he wasnt getting better. So they reached out to Trine Mogensen, a professor of immunology at Aarhus University in Denmark. It was really unclear what this infection was. And there was no evidence of bacterial infection or tuberculosis, Mogensen says. Stumped, she and her team sequenced the childs genome to see if this uncovered any clues. It came out, surprisingly, that there was a genetic mutation, she says.
What they had found was a mutation in the gene that codes for IFNAR2, a protein that binds to type I interferons. Interferons are a family of proteins that play an essential role in fighting off viral infections. Without type I interferons working well, the child would be unable to mount any kind of immune response to viruses such as Covid-19 and the flu.
Yet what virus the child was facing was still unclear. So Mogensen got in contact with Christopher Duncan, a clinician-scientist who studies viral immunity and interferons at Newcastle University in the United Kingdom. Duncan had been researching the very same genetic mutation for several years, first documenting it in a 2015 paper in the journal Science Translational Medicine. In that paper, he and his colleagues had found the genetic variant in a family from Ireland. A 13-month-old infant had suffered a severe case of encephalitisinflammation of the brainafter receiving the MMR vaccine, which contains live (but weakened) forms of the measles, mumps, and rubella viruses. The childs illness ultimately proved to be fatal.
Following the publication of that paper, Duncan and his colleagues had been contacted by researchers in Alaska, who had identified a couple of childrenunrelatedwho had run into major problems with multiple viruses and had the same genetic variant. He was also alerted to two children in northern Canada with a similar condition.
Knowing this, Mogensen and Duncan went back to the child from Greenlandand finally uncovered the root of his condition. They discovered that three weeks before falling ill, he had also been vaccinated with the live MMR vaccine. (The child survived and is now healthy.) Duncan and Mogensen published their findings in April in the Journal of Experimental Medicine.
But now the team wanted to know if there were more people carrying this uncatalogued genetic mutation. They had noted that the boy from Greenland and the children from Alaska were all of Inuit or Alaska Native heritage. They trawled through the genetic records of 5,000 Inuit and found the variant was surprisingly common: In fact, 1 in 1,500 people in the Inuit population were carrying it. That was hugely surprising, Duncan says.

BRCA Experts Rally to Research DNA Repair for Better Breast, Ovarian and Other Cancer Treatments – Yale School of Medicine
Posted: at 7:15 pm
When it comes to unlocking the secrets of DNA repair, Ranjit Bindra, MD, PhD, doesnt think in terms of just resources. The Harvey and Kate Cushing Professor of Therapeutic Radiology and professor of pathology favors a far mightier word: armamentarium. Based on the Latin word for armory, it describes the collection of medicines, equipment, and techniques utilized by a medical practitioner for a field of study.
Yale Cancer Center has an especially impressive armamentarium in the study of BRCA1 and BRCA2, proteins involved with DNA repair that, when mutated, can cause breast, ovarian, prostate, and pancreatic cancers. So when a $1 million grant became available for BRCA gene research from the Gray Foundation in 2018, a diverse team of Yale experts whose perspectives on BRCA gene-driven malignancies provide a 360-degree view from bench to bedside combined their collective skills to secure the sizable gift.
In the three years since, Yales team has made significant advances in targeting the BRCA gene-dependent DNA repair axis for cancer therapy.
Both the BRCA1 and BRCA2 protein are involved in DNA repair, said Megan King, PhD, associate professor of cell biology and of molecular, cellular and development biology, and co-leader of the Radiobiology and Genome Integrity Research Program at Yale Cancer Center. However, the work weve done has shown us that they have fundamentally different mechanisms. Thats important, because typically in clinical trials we lump together patients with BRCA1 and BRCA2 mutations. We need to think about these patient populations differently.
Those mechanisms affect which kind of therapies might work once cancer patients relapse on PARP inhibitors, a treatment that stops PARP proteins from repairing DNA damage in cancer cells and leads to cell death. For example, King has identified that if BRCA1 tumors stop expressing the 53BP1 or REV7 proteinboth of which play a role in repairing DNA double-strand breaksthey become resistant to PARP inhibitors. Thats because the absence of those proteins allows a third enzyme, called the Bloom syndrome protein (BLM), to not only resume the resection of DNA double-strand breaks, but go into repair overdrive, called hyper-resection.
Kings research identified BLM as a novel therapeutic target. She already has a candidate in mind for the job: a new class of drugs called ATR kinase inhibitors. The ATR kinase communicates DNA damage to the cell and activates DNA damage checkpoints, which arrest the cell cycle to provide time for repairs.
BLMs hyper-resection is a vulnerability that makes it sensitive to ATR inhibitors, King explained. She is working to design a clinical trial for ATR inhibitors in BRCA1 patients with fellow Gray Foundation team member Patricia LoRusso, DO, professor of medicine and associate cancer center director of experimental therapeutics.
The teams expertand a world experton BRCA2 is Ryan Jensen, PhD, associate professor of therapeutic radiology and pathology. He was the first scientist to purify and study the properties of the full-length BRCA2 protein. In collaboration with AstraZeneca, Jensen has focused on three BRCA2 reversion alleles, containing deletions in the BRCA2 gene that reactivate DNA repair functions, in tumor cell DNA from ovarian cancer patients who relapsed on a PARP inhibitor.
Hes currently researching whether these alleles alone cause resistance to PARP inhibitors and other cancer treatmentsand therefore, these studies could impact clinical management of patients harboring BRCA2 mutations. Furthermore, by leveraging genetic changes in BRCA2 directly from patients, Jensens team hopes this reverse translation approach will accelerate our understanding of why BRCA2 plays such a crucial role in responding to PARP inhibitors.
Enter Bindra, whose expertise in drug development drives the translation of these laboratory targets into patient therapies. His high-throughput testing capabilities enable him to conduct 96- and 384-well plate-based screening assays in PARP-nave and resistant cell lines. Where it used to take one day to analyze one well of a microplate, Bindra can now look at 384 tiny wells overnight and analyze the images and discover patterns automatically.
Of even greater excitement is Bindras comprehensive library of DNA repair inhibitor and damaging agents. He mixes and matches them in new therapeutic combinations to create novel compounds that can synergize or replace current PARP inhibitors.
When we do this testing in an academic setting instead of a pharmaceutical one, were able to profile all drug candidates out there and focus in an unbiased manner on the best combinations to move forward, Bindra said. This is not pie-in-the-sky scientific inquiry. Because they are clinical focused, these new combinations can be tested in clinics in a matter of one to two years.
Bindras cell lines have proven invaluable in Yales DNA repair research beyond the bounds of the Gray Foundation grant.
Faye Rogers, PhD, associate professor of therapeutic radiology, contributes her knowledge in DNA damage repair to the Gray Foundation team but is also pursuing numerous other research endeavors. She tapped the library for a cell line in her research on the use of endophytes to develop novel cancer-fighting compounds. Endophytes are fungi or bacteria that live symbiotically with plants and can produce the same natural products as their plant host. Theyre known as an untapped source for finding novel bioactive natural products.
An undergraduate student in Rogers lab collected endophytes for study while in Ecuador with Yales Rainforest Expedition and Laboratory Course. Rogers has identified one that produces a compound that inhibits DNA double-strand break repair in cancers with repair deficiencies, such as PTEN-deficient glioblastomas. Were now moving forward to come up with a synthetic version of this compound and conducting some medicinal chemistry to improve its efficacy, she said.
Rogers has returned the favor to the Bindra library. She has advised Bindas students in how to synthesize new classes of DNA repair inhibitors and damaging agents that will further expand Bindras testing capabilities of new compounds. Their teamwork is an example of the cross-disciplinary collaboration exemplified by the Gray Foundation team.
When you bring together people with different skills and perspectives, Bindra said, it adds so much more value to the conversation. And adds yet more invaluable tools to Yales DNA repair armamentarium.

Protein linked to intellectual disability has complex role Washington University School of Medicine in St. Louis – Washington University School of…

Finding therapies for fragile X may depend on understanding the many ways proteins loss affects brain
Researchers at Washington University School of Medicine in St. Louis have identified a previously unknown function for the fragile X protein, the loss of which is the leading inherited cause of intellectual disability. The researchers showed that the protein modulates how neurons in the brains memory center process information, a central part of learning and memory.
Fragile X syndrome, the leading inherited cause of intellectual disability, is due to a genetic mutation that largely eliminates the fragile X protein, a critical element of normal brain development and function.
The fragile X protein modulates neuronal functions, including neurons within the so-called GABAergic system that regulates the activity of neural circuits. The proteins absence throws that system off kilter, and so far, experimental therapies designed to reset the system by compensating for the missing proteins functions have not been effective in clinical trials.
Now, researchers at Washington University School of Medicine in St. Louis have identified a previously unknown role for the fragile X protein in the GABAergic system. They have shown that the protein regulates the opening and closing of the GABA-A receptor in neurons from the brains memory center, thereby influencing how such neurons process information, a central part of learning and memory.
The findings, published May 17 in Cell Reports, indicate that the fragile X proteins role is more complex than previously thought, and that finding effective therapies may depend on a more nuanced understanding of the myriad ways loss of this protein affects the brain.
People think that since fragile X is related to the loss of a single protein, it is a simple disease that we can quickly understand and fix, said senior author Vitaly A. Klyachko, PhD, a professor of cell biology & physiology. But the reality is that the more we study, the more we understand its not simple at all. I think part of the reason why clinical trials fail may be because we dont really understand whats going on very well. It is possible that we need to fix more than one mechanism at the same time for patients to see any meaningful improvement.
People with fragile X syndrome have intellectual or learning disabilities, social and behavioral problems, and characteristic physical features such as large ears and long faces. They also often are noted for their friendly dispositions. The condition affects about 1 in 7,000 males and 1 in 11,000 females, with males typically more severely affected. The fragile X gene is located on the X chromosome, so females inherit one good and one bad copy of the gene, but males have only the bad copy. There are no treatments that address the underlying cause.
The GABAergic system is based on the transmission of gamma aminobutyric acid (GABA) from one neuron to another. When it arrives, GABA binds to a receptor molecule and triggers a cascade of events in the receiving neuron that results in suppression of the activity of that neuron. An overactive GABAergic system puts people to sleep; an underactive one is linked to depression, anxiety and epileptic seizures.
To better understand the role of fragile X protein in the GABAergic system, Klyachko and first author Pan-Yue Deng, MD, PhD, an associate professor of cell biology & physiology, studied neurons from the brains of mice with and without the fragile X protein. Specifically, they recorded the activity of key information-processing neurons controlled by the GABAergic system in the hippocampus, the brains learning and memory center. Such neurons sense the presence of GABA primarily by using the so-called GABA-A receptor.
The receptor is a channel that can open to allow negatively charged chloride ions to flow into the cell to modulate its activity. The researchers found that fragile X protein influences how much time the GABA-A receptor spends open and how much chloride it allows into the cell, thereby setting the baseline electrical charge inside the neuron. This baseline charge, in turn, affects the neurons ability to distinguish between multiple signals that arrive at nearly the same time, a critical mechanism of pattern separation essential for learning and memory formation.
The fragile X protein directly interacts with receptors that play a major role in the way neurons process information, Klyachko said. This is an additional function for the fragile X protein, and it may be an important one. These neuronal receptors are everywhere, and they control many critical brain functions.
But Klyachko cautions against assuming that these findings can be easily translated into therapies for people living with fragile X syndrome. The GABAergic system is complex, and small tweaks can have unexpected and far-reaching effects on brain function, he said.
I think there is a very strong desire an understandable one to immediately translate each discovery into a clinical trial, Klyachko said. But if we dont understand all of the functions this protein has and we try to go after one specific mechanism, it may destabilize the other ones, and the end result is that people dont get better. An entirely different approach to treating this disease may be possible, but I think we need to first understand much more about how it works. This is just the first stepping stone in a new direction.

CU School of Medicine Research Defines the Role of HDAC6 in Regulating Heart Stiffness – University of Colorado Anschutz Medical Campus
Posted: at 7:15 pm
Researchers at theUniversity of Colorado School of Medicine have discovered an enzyme that regulates heart stiffness, setting the stage for developing novel treatments for heart failure.
The enzyme,histone deacetylase 6 (HDAC6), has been studied in the context of many diseases, including heart disease, but CU School of Medicine researchersTimothy McKinsey, PhD, professor of medicine in theDivision of Cardiology, andKathleen Woulfe, PhD, assistant professor of medicine in the Division of Cardiology, recently discovered a new role for HDAC6 in the regulation of myofibrils, the contractile units of the heart. The research was published May 16 in The Journal of Clinical Investigation.
When your heart is pumping and relaxing optimally, it's at a certain stiffness, McKinsey says. Stresses including aging, hypertension, and obesity can cause the heart to become too stiff, preventing it from relaxing and filling with blood efficiently,which leads to something called diastolic dysfunction. In other instances, the heart is not stiff enough, so it can't pump effectively, which leads to systolic dysfunction. Both conditions are life-threatening.
The CU researchers found evidence that HDAC6 acts on titin, a massive myofibril protein that contributes to heart stiffness. HDAC6 appears to remove a chemical modification known as acetylation fromtitin.When HDAC6 is inhibited, titin causes the heart to become stiffer; when HDAC6 is activated, the heart becomes less stiff. In the future, once cardiologists determine which type of dysfunction a patient has, it might be possible to therapeutically adjust HDAC6 enzymatic activity or levels to help the heart to pump and relax at an optimal stiffness.
Heart failure is still a huge problem that affects millions of people worldwide, McKinsey says. Even though there are medications to treat heart failure, people with the condition still often have poor quality of life and die at an alarming rate. We think this discovery could provide a novel avenue for treating heart failure through a distinct mechanism.
The progress of therapeutically manipulating HDAC6 to treat heart failure is helped along by the fact that HDAC6 inhibitors are actively being developed to treat other conditions, including neurodegeneration and cancer, though McKinsey cautionsthat the heart needs to be monitored more carefully in people receiving HDAC6 inhibitors.
"Our data suggest that in some cases, if you inhibit this enzyme, the heart might get too stiff, McKinsey says. Nevertheless, we firmly support continued clinical development of HDAC6 inhibitors, since this class of compounds holds great promise for treating a variety of devastating diseases, including certain forms of heart failure.
The CU researchers plan to continue to study the role of HDAC6 in heart stiffness, including testing HDAC6 inhibitors in preclinical models of systolic heart failure where titin is too compliant, and developing gene therapy to provide activated HDAC6 to hearts that are too stiff. Much of their work takes place in Woulfes laboratory, which is one of a handful of labs in the world that can isolate and study myofibril mechanics.
We are able to isolate proteins that direct contraction and relaxation in the heart in a way that preserves the mechanical function, Woulfe says. We can do this from tissue that's frozen, from our human heart bank, or from animals. We take away everything else except for those proteins that contract and relax. They are the fundamental basis of the function of the heart.This system enabled us to discover that HDAC6 directly regulates myofibril stiffness, most likely by deacetylating titin.
We think this is a major finding, and there's still a lot more to do, McKinsey adds. Scientific discovery is a series of building blocks, and we believe this is a key building block that allows us to understand the mechanics of the heart better at a molecular level, and also suggests therapeutic potential. We're going to keep vigorously working on the details of HDAC6 action in the heart.
This work was partially supported by theConsortium for Fibrosis Research & Translation, a program funded by the CU School of Medicine and co-directed by McKinsey. It aims to improve understanding of fibrotic diseases across various organ systems.
In addition to Woulfe and McKinsey, the other researchers on the study areYing-Hsi Lin, Jennifer Major, Joshua Travers, Sara Wennersten, Cortney Wilson, Korey Haefner, Maria Cavasin, Mark Jeong, Yu Han, Amrut Ambardekar, and Maggie Lam from the CU School of Medicine Division of Cardiology; Scott Ferguson from the Cardiovascular and Pulmonary Research Laboratory in the CU Department of Medicine; Tim Liebner and Chunaram Choudhary from the University of Copenhagen, Denmark; Zaynab Hourani and Henk Granzier from the University of Arizona; and Michael Gotthardt from the Max Delbruck Center for Molecular Medicine in Germany.
