Type 1 diabetes: Reprogramming liver cells may lead to new treatments – Medical News Today

Researchers have discovered a way to reprogram mouse liver cells into precursor pancreatic cells by changing the expression of a single gene. They suggest that the finding is an important step toward showing that reprogramming liver cells might offer a way forward for the treatment of type 1 diabetes in humans.

The team - led by researchers from the Max Delbrck Center for Molecular Medicine in Berlin, Germany - reports the study in the journal Nature Communications.

Diabetes is a chronic disease that develops either when the body cannot make enough insulin, or when it cannot effectively use the insulin that it does make. Insulin is a hormone that regulates blood sugar, or glucose, and it helps to convert glucose from food into energy for cells.

Uncontrolled diabetes leads to high blood sugar, or hyperglycemia, which over time causes serious damage to many parts of the body, including the heart, blood vessels, nerves, eyes, and kidneys.

In the United States, an estimated 29.1 million people have diabetes, including 8.1 million who are undiagnosed.

The most common type of diabetes is type 2, in which the body cannot use insulin effectively. Type 1 diabetes, in which the body does not make enough insulin, accounts for around 5 percent of diabetes cases in adults.

The new study is likely to interest researchers developing treatments for type 1 diabetes. In people with type 1 diabetes, the immune system attacks the insulin-producing beta cells of the pancreas.

Researchers in regenerative medicine are exploring ways to generate new populations of pancreatic beta cells as a possible avenue for the treatment of type 1 diabetes.

The new study concerns a method called cell reprogramming, in which it is possible to convert one type of cell into another type of cell, by tweaking genes.

An obvious source of cells for reprogramming into insulin-producing beta cells might be other types of cell in the pancreas.

In their study paper, the researchers mention other research that shows such pancreatic cells display a high degree of the necessary "cellular plasticity."

However, the researchers chose to focus on liver cells because, from a clinical perspective, they offer important advantages over pancreatic cells; for example, they are more accessible and abundant.

They also cite studies that have partially corrected hyperglycemia in diabetic mice by reprogramming liver cells into pancreatic beta cells.

The new study shows how just by changing the expression of a single gene called TGIF2, the team was able to coax mouse liver cells to take on a less specialized state and then stimulate them to develop into cells with pancreatic features.

When the researchers transplanted the modified cells into diabetic mice, the animals' blood sugar levels improved, suggesting the cells were behaving in a way similar to pancreatic beta cells.

The researchers identified TGIF2 (Three-Amino-acid-Loop-Extension homeobox TG-interacting factor 2) by running gene expression profiling tests on immature liver and pancreas cells isolated from mouse embryos as the cells differentiated toward their particular cell fates.

They found that at a particular differentiation branchpoint, the expression of TGIF2 changes in opposite directions as the cells commit to either liver or pancreatic fates.

The authors note that their study shows that "TGIF2 is a developmental regulator of pancreas versus liver fate decision," and when expressed in adult mouse liver cells, it suppresses the transcription program for liver cells and induces a subset of pancreatic genes.

There is still a lot of work to do to investigate whether the results with mice translate to humans. The team has already started working on human liver cells.

"There are differences between mice and humans, which we still have to overcome. But we are well on the path to developing a 'proof of concept' for future therapies."

Ebolaviruses need very few mutations to cause disease in new host … – Phys.Org

February 15, 2017 Ebolavirus Protein VP24. Credit: University of Kent

Kent researchers have identified how few mutations it can take for Ebolaviruses to adapt to affect previously resistant species.

Ebola is one of the world's most virulent diseases, though rodent species such as guinea pigs, rats and mice are not normally susceptible to it. However, through repeated infection of a host animal, Ebola virus strains can be generated that replicate and cause disease within new host rodent species.

Scientists in the University of Kent's School of Biosciences examined the changes associated with Ebolavirus adaptation to rodents including guinea pigs and mice across four different studies. They found that only very few mutations, probably fewer than five, are required for the virus to adapt.

In particular, a change in the Ebolavirus protein VP24 seems to be critical for Ebola viruses to infect a new animal species. Ebolaviruses infecting domestic species, including pigs and dogs, may also result in virus changes that may increase the risk to humans. Reston viruses, Ebolaviruses that have not been shown to cause disease in humans, so far, are known to circulate in domestic pigs in Asia.

The research was performed by Dr Mark Wass (Senior Lecturer in Computational Biology), Professor Martin Michaelis (Professor of Molecular Medicine), and Dr Jeremy Rossman (Senior Lecturer in Virology) and members of their research groups.

The research, entitled Changes associated with Ebola virus adaptation to novel species, was published in the journal Bioinformatics.

Uncovering Metabolism’s Clockwork – Northwestern University NewsCenter

Joseph Bass, MD, PhD, is the chief and Charles F. Kettering Professor of Endocrinology in the Department of Medicine at Feinberg.

This story originally appeared in the Breakthroughs Newsletter.

Timing is everything may be an old clich, but for Joseph Bass, MD, PhD, its also a reflection of an emerging discovery in physiology: that the bodys circadian clocks are in fact critical to driving a host of behaviors, processes and pathways including those associated with several diseases and pathologies.

Bass, chief of Endocrinology, Metabolism and Molecular Medicine in the Department of Medicine, focuses his research on illuminating how the bodys clocks regulate feeding behavior and glucose metabolism, and identifies how disruptions in that overarching circadian system play a role in metabolic disease. The goal of the research is to develop a deeper understanding of the clock and its mechanisms, which may eventually lead to novel therapies for widespread disorders like obesity and diabetes.

The field of circadian time has been an area of excellence at Northwestern for more than 20 years, said Bass, also the Charles F. Kettering Professorship of Medicine and a member of the Robert H. Lurie Comprehensive Cancer Center of Northwestern University. What were trying to do now is take advantage of our know-how to identify new pathways and drugs for those pathways that could, for example, augment insulin secretion and improve diabetes.

Its long been known that the body possesses a master circadian clock, located in the brain, in the suprachiasmatic nucleus of the hypothalamus. But it wasnt until more recently, as the field of circadian time rapidly advanced, that it was discovered there are also distinct clocks residing in nearly every cell of the body.

The master clock cued by internal factors and environmental signals like light holds the rhythm across all the bodys peripheral clocks, regulating behavior and biological processes throughout the 24-hour light-dark cycle. But when individual clocks fall out of tune with the master timekeeper, the breakdown in synchronization can contribute to a range of disorders, including diabetes.

My focus has increasingly been drawn toward understanding the perspective of time as a variable in biochemical processes that determine our drive to eat in turn affecting bodyweight and regulate blood sugar control, Bass said.

Bass, who joined Northwestern in 2000, arrived at an opportune time in the history of circadian clock discovery. Seminal work in the late 1990s by Fred Turek, PhD, professor of Neurology and Psychiatry and Behavioral Sciences, and Joseph Takahashi, PhD, a former professor of Neurology, for the first time pinpointed and cloned the genes that drive circadian function in mammals.

There was this intersection of critical developments at Northwestern that really opened the field, Bass said. The collaborative environment then enabled me to join together my background in endocrine, metabolic and medical physiology with these powerful strategies from genetics to try to understand how the clock regulates behaviors and physiologic systems.

In a landmark paper published in Science in 2005, Bass, together with Turek and Takahashi, demonstrated that a misaligned biological clock impaired metabolism, increasing the prevalence of obesity and metabolic syndrome. In the study, mutant mice with a dysfunctional clock gene experienced a 35 percent increase in fat mass compared to wild-type mice.

The paper was the first to provide genetic evidence that the clock system regulates both body weight and glucose metabolism; that was key, said Bass, who is also co-director of the Center for Diabetes and Metabolism and of the Comprehensive Metabolic Core.

Numerous breakthroughs in the metabolism-clock connection followed over the next 15 years of Bass tenure at Northwestern. In Nature in 2010, Bass and his team first reported that beta-cells in the pancreas require a clock in order to produce insulin. In a subsequent study building upon those findings, Bass laboratory, together with co-investigator Grant Barish, MD, used next-generation genome sequencing to pinpoint the precise set of genes in the pancreas that are controlled by the clock transcription factors. The findings were published in Science in 2015.

Joe has really been a leader in establishing a very direct connection between the circadian clock and diabetes, said Barish, assistant professor of Medicine in the Division of Endocrinology, Metabolism, and Molecular Medicine. Particularly in this most recent study, the discovery of the underlying regulatory mechanism by which the circadian clock controls the secretion of insulin the principal hormone responsible for glucose homeostasis really cements a link between the clock and aspects of insulin, diabetes and related physiology.

The anticipation is that such fundamental discoveries may eventually inform the development of novel therapeutics for diabetes and other diseases. While were still very early in this, we know that some features of these circadian transcription factors are targetable and, to some extent, are amenable to pharmacologic manipulation, Barish said.

Bass findings also have applications for the treatment of a wider range of disorders, as the bodys metabolism of drugs is in part influenced by the circadian system, an area of study called chronopharmacology. For example, statins are largely administrated at night because the clock coordinates the synthesis of cholesterol to occur at night. Its likely that this is just the tip of the iceberg, and that there are many other processes targeted with drugs that are controlled by the same clock mechanism, Bass said.

In ongoing research, Bass laboratory is also striving to uncover how the clock helps regulate production of a key molecule called NAD+. The connection was first reported in a pair of papers Bass published in Science in 2009 and 2013, with first author Kathryn Ramsey, PhD, and first author Clara Peek, PhD, respectively, both research assistant professors of Medicine in the Division of Endocrinology, Metabolism, and Molecular Medicine.

NAD+ has been shown to be central to the mechanism that connects life span and aging to nutrition. Were now trying to understand how it is that nutrition and clocks influence aging, and we think one of the ways this comes about is through the control of NAD+, Bass said. He is collaborating with colleagues in chemistry, including Milan Mrksich, PhD, professor of Cell and Molecular Biology, and Navdeep Chandel, PhD, David W. Cugell Professor of Medicine and of Cell and Molecular Biology, to address such questions.

Interactions with other groups at Northwestern have enabled us to make key advances in our understanding of the clock and in how its controlling other physiologic systems, Bass said. Because of the history of discoveries here, were now in a position to be on the ground floor in using genetic approaches to get at questions that have been asked for a long time in a more descriptive way.

You’re hardwired to go mad – Independent Online

Washington - American and Japanese researchers said on Thursday that they had found a genetic mutation that causes obsessive-compulsive disorder and other mental illnesses and said some patients had a second mutation that made their conditions worse.

The rare finding could make it easier to discover better treatments for the disorder, one of the top 10 leading causes of disability worldwide.

Dr Norio Ozaki of Fujita Health University School of Medicine in Japan and colleagues at several American institutions - including the University of Pittsburgh and Yale University - worked on the study, which was published in the journal Molecular Psychiatry.

The gene is called the human serotonin transporter gene, hSERT, and helps control how the body uses serotonin, a message-carrying chemical or neurotransmitter linked with mood.

Some anxiety drugs and antidepressants target serotonin, but the researchers said patients with the mutations are not helped by these drugs.

"In all of molecular medicine, there are few known instances where two variants within one gene have been found to alter the expression and regulation of the gene in a way that appears associated with symptoms of a disorder," said Dr Dennis Murphy of the National Institute of Mental Health, who worked on the study.

The researchers analysed DNA from 170 people, including 30 patients with obsessive-compulsive disorder (OCD), 30 with eating disorders such as anorexia and 30 with seasonal affective disorder - which can cause depression and other symptoms in dark winter months.

They also looked at the DNA of 80 healthy people.

A specific mutation in the hSERT gene was seen in two patients with OCD and their families, but not in other patients.

With such a rare mutation showing up, the researchers believe it is likely to be found in other families with OCD and related disorders.

They interviewed relatives of the patients and found six of the seven people with the mutation had an obsessive-compulsive disorder, and some also had anorexia, Asperger's syndrome, which is a form of autism, social phobia or were abusers of alcohol.

A second mutation was found in hSERT in two patients, giving them a "double dose." The patients and their siblings had especially difficult to treat versions of OCD, the researchers said.

New method reduces adverse effects of rectal cancer treatment – Medical Xpress

February 10, 2017

A new study from Karolinska Institutet shows that short-course preoperative radiotherapy combined with delayed surgery reduces the adverse side-effects of rectal cancer surgery without compromising its efficacy. The results are presented in the journal The Lancet Oncology.

Rectal cancer affects some 2,000 men and women in Sweden every year. Preoperative radiotherapy was gradually introduced in the early 1990s, with a consequent improvement in prognosis for people with rectal cancer and reduction in the risk of local recurrence.

"Back then we showed that preoperative radiotherapy reduces the risk of local recurrence by over 50 per cent for patients with rectal cancer," says principal investigator Anna Martling, senior consultant surgeon and professor at Karolinska Institutet's Department of Molecular Medicine and Surgery. "Thanks to our results, radiotherapy is recommended to many rectal cancer patients."

However, radiotherapy can cause adverse reactions and the optimal radiotherapeutic method and the interval between it and the ensuing surgery have been mooted.

The study now presented in The Lancet Oncology is based on the claim that the adverse effects of rectal cancer treatment can be reduced by administering more but lower doses of radiation for a longer time, or by increasing the interval between radiotherapy and surgery. These hypotheses have now been tested in a study in which rectal cancer patients were randomly assigned to three different treatment arms:

The results of the study show that patients with delayed surgery develop fewer complications with equally good oncological outcomes. It also showed that there is no difference between long-course and short-course radiotherapy other than that the former considerably lengthens the time for treatment.

"The results of the study will give rise to improved therapeutic strategies, fewer complications with a sustained low incidence of local recurrence, and better survival rates for rectal cancer patients," says Professor Martling. "The results can now be immediately put to clinical use to the considerable benefit of the patients."

Epigenetics Around the Web: Chemo affects sperm? Cancer causes. Younger looking skin? – Genetic Literacy Project

This weeks features include: Genetic and epigenetic diversity in cancer; epigenetics is the new buzzword in beauty; and the long-lasting impact of chemotherapy.

Im not suggesting that you shouldnt use chemo. In fact, I would suggest that you probably should use the chemo. Im just saying that there are some preventative things that may need to be put in place before you use the chemo if possible.

Michael Skinner, a professor in the WSU School of Biological Sciences and Center for Reproductive Biology

Genetic mutations are a root cause of cancer. But your cells dont just pick up a mutation and turncancerous. In fact, a cell can rack up numerous mutations and not pose adanger. There is no set number of mutations that must be registered, but ratherthe trigger point depends on what genes are affected and in what cell type (among other factors). From person to person, tumors can show a wide range of genetic diversity, even among people with the same affected tissue type and stage.

Overall childhood cancers seem to have a much lower level of genetic diversity, puzzling researchers. One example is Ewing sarcoma (EWS), a bone cancer found mainly in teenagers. Asingle genetic defectthe EWS-ETS fusiondefines most tumors, and overall they are similar genetically, which is perplexing because progression and prognosis can vary drastically from patient to patient. A recent study, published inNature Medicine,found that EWS tumors have a striking level of epigenetic diversity, which may explain theses observed differences.

Researchers at CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences found that EWS tumors have a striking amount of hypomethylation (a process that generally leads to the product of a gene, generally a protein, being produced in an excessive amount) on the disease-defining genetic defect. Furthermore, patients with metastatic EWS show even more alterations in methylation. This finding could help physicians identify which patients are at risk for poorer outcomes.

Maybe shes born with it, maybe itsMaybellineor maybe its epigenetics? Thecosmetics industry is beset by faddish claims that various products and tests can help make your skin younger and restore itsnatural tautness by harnessing the power of epigenetics. One company, Mibellebiochemistry group, claims that a protein calledroyalactin, derived from bees, can induce epigenetic changes in human skin cells that accelerate epidermal regeneration for smoother skin, activates the cellular cleaning process and reveals a more evenly toned skin. Another, Geneu,says they can make a customized serum by looking at your unique epigenetic and genetic profile that will enhance your skins beauty.

Thescience behind these claims is shaky at best. Epigenetic changes are made onto DNA and change the activity of certain genes. But skin cells dont have active DNA. They slowly fill up with keratin, lose their DNA and die. So a cream thattargets geneexpression in the skin is highly unlikely to affect your skins age. Unless you grow crows feet from worrying about your bank account as one of Genus tests can run you $2,200.

Chemotherapy is not perfect. Anyone who has gone through it can tell you it is a miserable process. There are a number of adverse effects that can be severely debilitating: Nausea, fatigue, pain, GI distress, hair loss, vomiting, fever, chills and rashes, and the list goes on. Most of these side effects are short-lived and if the drugs works, the results are pretty fantastic.

But for a number of chemical critics, these adverse demonstratea far-reaching conspiracy by the pharmaceutical industry to keep us sick so they can bleed us of every last dime. (I wont link to any activist sites, but the links are easy to find.)

These baseless and outrageous claims cloud chemotherapy and make it difficult for doctors and scientists to seriously discussions with patients its long-lasting impact for fear a patient will elect an alternative (and ineffective) treatment.

A recent study published inPLOS Oneby Washington State University epigeneticist Michael Skinner highlights this struggle. Skinner found that chemotherapy changed methylation patterns in the sperm of men, which could affect gene expression during any of theiroffsprings development. The study is backed up by previous research onrodents, and Skinner saidhis results are very reproducible. But hismain concern seems to be how his findings might be misrepresentedby activists:

Im not suggesting that you shouldnt use chemo. In fact, I would suggest that you probably should use the chemo. Im just saying that there are some preventative things that may need to be put in place before you use the chemo if possible.

If alterations on the genomes of sperm are found to affect a mans children, it is not proof of a conspiracy by industry to harm patients; nor is it a reason not to undergo chemotherapy. Theymerely indicate that young males with cancer may need to discuss with their physicians about taking precautionary steps to ensure that, after they receive this life-saving medicine, they can still have a healthy family. One example would befreezing their sperm before receiving their first round of treatment.

Cancer Breakthroughs 2020: Soon-Shiong’s research program gets new name – TribDem.com

WINDBER An international cancer research effort involving the Windber hospital and research center has been renamed to reduce confusion and better reflect its success, its founder announced.

We are renaming and branding Cancer MoonShot 2020 to Cancer Breakthroughs 2020, a name that elevates the importance and progress of our work to what it truly is breakthroughs, Dr. Patrick Soon-Shiong said in a press release.

Soon-Shiongs nonprofit, Chan Soon-Shiong NantHealth Foundation, is the parent of Chan Soon-Shiong Medical Center at Windber and Chan Soon-Shiong Institute of Molecular Medicine at Windber.

Both are participating in the Cancer Breakthroughs 2020 collaboration of research organizations, hospitals and businesses.

We are extremely proud to play a role in Cancer Breakthroughs 2020, said Tom Kurtz, president and CEO of both Windber facilities.

The name is an accurate description of this action-oriented initiative.

The change will address confusion with other cancer moonshot programs Soon-Shiong said.

It may also help settle a lawsuit filed by the University of Texas MD Anderson Cancer Center, which has been using the Cancer Moon Shotstagline since 2012, the federal lawsuit says.

In addition to the MD Anderson Moon Shots, the federal government has its ownCancer Moonshot.

Two days after Soon-Shiong unveiled his former Cancer MoonShot 2020 in January 2016, then-President Barack Obamacredited his vice president, Joe Biden, with suggesting with a new moonshot, America can cure cancer.

In his State of the Union Address, Obama went on to announce a national Cancer Moonshot effort, putting Biden in charge of Mission Control.

Windbers research program is involved in the national Cancer Moonshot through its partnership with Walter Reed National Military Medical Centers John Murtha Cancer Center in Bethesda, Maryland.

Soon-Shiong says the Cancer Breakthroughs 2020 name is more appropriate.

With recent discoveries in molecular science and rapid advancements in supercomputing technology, we are now on the path that will forever change the way cancer is diagnosed and treated, he said in a press release.

It is no longer a dream no longer just an aspiration. It is the forging of real breakthroughs, long overdue in the fight against cancer, that are giving millions hope that will subdue cancer by harnessing the most powerful defense against this deadly disease ones own immune system.

New archive developed by UNM doctor to advance precision medicine and drug development – UNM Daily Lobo

According to a UNM Health Sciences Centerrelease,Tudor Oprea, a professor of Internal Medicine and chief of UNMs Translational Informatics Division, and a teamcollaborators, have pulled back the curtain onan open-source archive for drug discovery, development and safety that is 20 years in the making.

According to the release, the group recently published their work in the journal "Nature Reviews Drug Discovery."

This is a landmark paper, David Schade, a distinguished professor in the UNM School of Medicine who oversees clinical research in the Department of Internal Medicine, was quoted as saying in the release. Diseases that were not treatable 10 years ago are now treatable thats because of new medications that have been developed and approved by the Food and Drug Administration.

While new drugs have saved lives, they can also complicate treatment. According to the release,doctors often use a combination of drugs to treat diabetes, for example, but they must make sure those drugs compliment one another and no dangerous side appear when combined.

What we want to do, Schade is quoted as saying in the release, is hit multiple targets that are causing the disease.

According to the release, Opreas archive will help doctors to do just that. Olivier Rixe, who oversees all clinical research at the UNM Comprehensive Cancer Center, agrees and plans to use Opreas archive to speed the process of drug discovery and development.

Oprea, now a professor at thecenter, started the drug database 20 years ago when he was a drug developer, according to the release. He archived drug targetsmolecules that drugs act on to make the cell change its behaviorlater expanded his list to include properties of the drugs themselves along with any information about how they acted on their targets.

According to the release, in order to develop the information, Oprea and his international collaborators had to mine data from all over the world, then correctly map the drugs molecular structures and search for data on the diseases the drugs helped to treat.

They collected data on the drugs effects on humans and animals and listed what scientists had learned about how the drugs reacted with the proteins in cells, according to the release.

In total, they cataloged 893 drug targets linked to their mode of action, a term that describes how drugs exert their therapeutic effect at the molecular level, along with 1,578 drugs approved by the FDA.

According to the release, the information is now publicly available through DrugCentral, a system that Opreas research team at UNM developed. DrugCentral resides at UNM and Oprea is building his team to be experts in drug discovery.

This type of expertise is rare, Oprea is quoted as saying in the release. We are one of the teams that has it.
