Longevity linked to good genes, good diet

Published: Sept. 6, 2012 at 5:12 PM

SANTA MONICA, Calif., Sept. 6 (UPI) -- Researchers in Sardinia say the longevity of the world's oldest siblings -- nine brothers and sisters ages 105-78 -- was due to good genes and a good diet.

"Italian newspapers reported that the Melis family had been recognized by [Guinness World Records] as officially being the world's oldest siblings," Phil Lempert, a food industry analyst, trend watcher and creator of supermarketguru.com, said in a statement.

"Residing on the island of Sardinia the nine brothers and sisters total 818 years between them. Consolata, the oldest, just turned 105, followed by Claudia 99, Maria 97, Antonio 93, Concetta 91, Adolfo 89, Vitalio 86, Vitalia 81, and Mafalda 78. Consolata has nine children, 24 grand children and 25 great-grand children."

Researchers at the University of Sassari in Sardinia said the family's longevity might be due to genetics, strong family traditions and the seasonal fruits and vegetables -- particularly pears, prunes, or plums -- that they consumed as part of their Mediterranean diet.

For example, pears are high in flavonoids when eaten with the skin, which contains about half of the fruit's dietary fiber -- beneficial in preventing type 2 diabetes, heart disease and some forms of cancer. The pears are also high in phytonutrients as well carotenoids -- providing antioxidant and anti-inflammatory protection, Lempert said.

"The high antioxidant content, combined with carotenoids in plums and prunes has been found to ward off macular degeneration, as well as being another good source of fiber," Lempert said.

'Junk' DNA: Not So Useless After All

Don Bishop / Getty Images

Junk. Barren. Non-functioning. Dark matter. Thats how scientists had described the 98% of human genome that lies between our 21,000 genes, ever since our DNA was first sequenced about a decade ago. The disappointment in those descriptors was intentional and palpable.

It had been believed that the human genome the underpinnings of the blueprint for the talking, empire-building, socially evolved species that we are would be stuffed with sophisticated genes, coding for critical proteins of unparalleled complexity. But when all was said and done, and the Human Genome Project finally determined the entire sequence of our DNA in 2001, researchers found that the 3 billion base pairs that comprised our mere 21,000 genes made up a paltry 2% of the entire genome. The rest, geneticists acknowledged with unconcealed embarrassment, was an apparent biological wasteland.

But it turns out they were wrong. In an impressive series of more than 30 papers published in several journals, including Nature, Genome Research, Genome Biology, Science and Cell, scientists now report that these vast stretches of seeming junk DNA are actually the seat of crucial gene-controlling activity changes that contribute to hundreds of common diseases. The new data come from the Encyclopedia of DNA Elements project, or ENCODE, a $123 million endeavor begun by the National Human Genome Research Institute (NHGRI) in 2003, which includes 442 scientists in 32 labs around the world.

ENCODE has revealed that some 80% of the human genome is biochemically active. What is remarkable is how much of [the genome] is doing at least something. It has changed my perception of the genome, says Ewan Birney, ENCODEs lead analysis coordinator from the European Bioinformatics Institute.

Rather than being inert, the portions of DNA that do not code for genes contain about 4 million so-called gene switches, transcription factors that control when our genes turn on and off and how much protein they make, not only affecting all the cells and organs in our body, but doing so at different points in our lifetime. Somewhere amidst that 80% of DNA, for example, lie the instructions that coax an uncommitted cell in a growing embryo to form a brain neuron, or direct a cell in the pancreas to churn out insulin after a meal, or guide a skin cell to bud off and replace a predecessor that has sloughed off.

What we learned from ENCODE is how complicated the human genome is, and the incredible choreography that is going on with the immense number of switches that are choreographing how genes are used, Eric Green, director of NHGRI, told reporters during a teleconference discussing the findings. We are starting to answer fundamental questions like what are the working parts of the human genome, the parts list of the human genome and what those parts do.

If the Human Genome Project established the letters of the human genome, ENCODE is providing the narrative of the genetic novel by fashioning strings of DNA into meaningful molecular words that together tell the story not just of how we become who we are, but how we get sick as well.

New book reviews the biology of synapses

Public release date: 6-Sep-2012 [ | E-mail | Share ]

Contact: Elizabeth Powers powerse@cshl.edu 516-422-4101 Cold Spring Harbor Laboratory

Synapses are bulbous structures where two neurons communicate. Neurotransmitter molecules released from the presynaptic terminal of one neuron diffuse to the postsynaptic terminal on the other, binding to receptors that lead to propagation or modulation of the signal.

Written and edited by experts in the field, The Synapse from Cold Spring Harbor Laboratory Press examines the highly complex structures of the pre- and postsynaptic regions, as well as the trafficking mechanisms that transport vesicles containing neurotransmitters. The contributors discuss how long-term potentiation (LTP) and long-term depression (LTD) of synaptic transmission form the basis of learning and memory. The roles of calcium signaling in regulating synaptic and cell function and techniques to study such signaling events are also covered.

This volume also includes discussions of synaptic dysfunction in disorders such as autism and Alzheimer's disease. It is an indispensable reference for neurobiologists, cell and developmental biologists, and anyone wishing to understand how the basic building blocks of the brain are put together and communicate.

Body Maps: See All Your Parts, Skin Removal Not Required

The interactive anatomy tool that facilitates patient-doctor communication and is "social media ready"

Phones won't ever replace doctors. An app for medical diagnosis can't put a gentle hand on your shoulder. It can't calm you with whispers and a warming embrace. Its fingertips aren't soft, smooth, inquisitive. It doesn't have the robust intuition, the seasoned experience, the authority to which you can surrender control...

But a new app from the good people at General Electricand Healthline can help doctors and patients get on the same page about anatomy -- what's hurting whom, and who's doing what where to help it. Among other things, it's designed to help physicians communicate as a visual aid in discussing diagnoses and treatment plans.That's something an app can do very well. It's called BodyMaps, and it involves this spinning apparition:

She does not grant wishes or respond to emotional cues. You can, though, make her spin around quickly (or slowly, slowly), so the app scores satisfactorily in the rubric for "imparts sense of omnipotence."

Beyond detailed anatomy, it also has 200 concise tutorials like "Why do I sneeze?"

Hint: It's related to the sneezing center.

The real highlight of BodyMaps, though, is the feature where you can annotate the images by drawing with your finger -- to illustrate your point. Because not all doctors are good with words, and not all words are good with doctors. You can only write in blue, black, or green. (Not red!)

After-school program highlights cooking, nutrition

Tuesday August 28, 2012

PITTSFIELD

Dr. Jacqueline Jones of Berkshire Pediatric Associates is partnering with The Nutrition Center to launch a new after-school kids cooking and nutrition education program in Pittsfield this school year.

The partners are acting under a $12,000 pediatric grant it received from CATCH (Community Access to Child Health), a national program of the American Academy of Pediatrics.

According to the Massachusetts Department of Public Health's Body Mass Index (BMI) screening data, 34 percent, or 2,559 children in the Pittsfield public school district are considered overweight or obese.

BMI is calculated by using a formula that compares a person's height and weight with a set of BMI standards by gender. If a person's BMI number is above the 85 percentile, they are considered to be at risk of obesity; a BMI above the 95th percentile is an indicator of obesity.

"Learning basic cooking skills during childhood has been shown to lead to life-long behavior changes for better health," said Peter Stanton, director of The Nutrition Center. He holds a master of science degree as a registered dietitian and is a state-licensed dietitian/nutritionist.

The nonprofit Nutrition Center provides community-based-nutrition education, cooking classes and clinical nutrition counseling for better health and disease prevention. This summer, it opened a new office and moved its administrative headquarters from Great Barrington to Pittsfield.

The

"[Obesity is] such a huge problem in our population. We want to give parents and kids tools to be healthy," said Jones.

Mt. Lebanon district recognized for student nutrition

A top Agriculture Department official will visit Mt. Lebanon on Friday to honor the school district for its commitment to student nutrition.

Janey Thornton, USDA deputy undersecretary, will meet with parents and school officials, dine with students and present the HealthierUS Schools Challenge award, a program started in 2004 to promote improved nutrition and healthier school environments.

The honor, shared with about 4,000 schools nationwide, covers a variety of criteria, Ms. Thornton said. Schools must show that a certain percentage of their students participate in school meals; that they've established a wellness policy with food guidelines; and that they offer nutrition education.

"It is more of a comprehensive approach to good nutrition and wellness throughout the school as opposed to just what's on the school menu that particular day," she said.

Mt. Lebanon has offered elementary students unlimited fruits and vegetables since the lunch program's inception. Before it started three years ago, elementary students either went home for lunch or brought food to school.

The district established the program to ensure students eligible for free or reduced-price meals were eating lunch, said Tazeen Chowdhury, district food service director.

Much of the produce served at the elementary schools is grown on local farms and arrives via a distributor. The district started a "farm of the month" program last year, and this month features fruits and vegetables from Laurel Vista Farms in Somerset.

The HealthierUS Schools Challenge application took about six months to compile. And in July, new national regulations took effect, requiring more fruits and vegetables for student lunches, among other changes.

The district's foresight, Ms. Chowdhury said, made the transition easier.

"We knew we were already on the ball with it," she said. "We were way ahead of the curve knowing that this is the direction we want to go."

Q&A: U of Cambridge’s Sharon Peacock on Next-Gen Sequencing for Public Health Surveillance

Name: Sharon Peacock Title: Professor of clinical microbiology, Departments of Medicine and Pathology at the University of Cambridge; Honorary consultant microbiologist at the Health Protection Agency and Cambridge University Hospitals NHS Trust; Honorary faculty at the Wellcome Trust Sanger Institute Education: BS in medicine, University of Southampton; MRCP, Royal College of Physicians, London; MS in medical microbiology, University of London; PhD, Oxford University and Open University Whole-genome sequencing has recently made strides as a tool that can be used in public health surveillance. Most recently, the National Institutes of Health published a study in which they used sequencing in real time during an outbreak to track transmission and make decisions about how to manage the outbreak (CSN 8/20/2012).

Earlier this summer, groups from the UK published studies in the New England Journal of Medicine and BMJ Open, demonstrating the ability of sequencing retrospectively to track MRSA outbreaks in hospitals (CSN 6/20/2012).

Sharon Peacock, an author of the NEJM study, has been making significant gains in bringing whole-genome sequencing into a public health setting.

Under grants from the UK Clinical Research Collaboration and the UK's Health Protection Agency she has been working alongside collaborators, such as Julian Parkhill's team at the Wellcome Trust Sanger Institute and David Aanensen at Imperial College, to develop tools that will enable public health organizations to adopt sequencing for surveillance and diagnostics.

Peacock also published an editorial recently in PLoS Pathogens on the use of sequencing in public health microbiology.

She is currently working within the Cambridge UKCRC consortium to develop databases of pathogen genomes and create interpretation tools for public health organizations, diagnostic laboratories, and health care workers.

Recently, Peacock spoke with Clinical Sequencing News about her work in bringing whole-genome sequencing into clinical microbiology for public health surveillance.

What is the goal of the Cambridge UKCRC consortium?

Our objective is to try and translate whole-genome sequencing into diagnostic and public health microbiology where it's been shown to make a difference either to individual patient care or public health surveillance. At the moment, we're working particularly on [methicillin-resistant Streptococcus aureus], but we're just in the process of expanding this out to a range of other pathogens that are important for human infection.

Can you describe the work that you're doing with MRSA?

UF to offer STEM degrees in Miami

Community college students in Miami have a chance to earn microbiology degrees from UF without the six-hour drive.

The National Science Foundations undergraduate education division awarded to UF and Miami Dade College last month a $1.7 million grant to increase the number of students graduating with degrees in science, technology, engineering and math.

The foundation is looking for innovative ways to bring community college students, particularly minorities, to bigger universities for life science degrees, said grant writer Eric Triplett, chairman of the UF College of Agricultural and Life Sciences microbiology and cell science department.

[The foundation is] willing for people to take risks, he said.

The grant will expand the distance-learning program UF and Miami Dade faculty launched last Fall. Miami Dade is a full partner in the program, Triplett said.

Miami Dade students who earn an associate of arts degree there and get minimum grades in certain prerequisite courses are eligible for the program.

Almost all the microbiology courses are available online, Triplett said. Miami Dade students can also attend shortened lab sessions on UFs campus.

The five-year grant will fund 20 $1,250 scholarships each semester for students at Miami Dade, Triplett said. About 10 research stipends at UF labs throughout South Florida will also be available.

The grant will also provide career workshops to educate students about job options after graduating with a microbiology degree.

Theres more to life than medical school, Triplett said.

Lost decades — Longevity gains decline for Blacks, Latinos and less educated

5th September 2012 0 Comments

By Paul Kleyman Contributing Writer

CHICAGO (Special from New America Media) The longevity gap between two Americas has widened since 1990, says a new study. One America is mostly white and well educated, and the other is ethnic or undereducated and dying about decade sooner than their more affluent counterparts.

The gap between college-educated whites and African Americans who did not complete high school is simply unbelievable, stated S. Jay Olshansky, lead author of the extensive new analysis published in the August issue of the prestigious health policy journal Health Affairs.

Former nurse Ollie Burton, shown last year at age 103 at the Kissito Healthcare's nursing home in Midland, Tex., represents the longevity exception.

The researchers, who crunched mortality numbers in key databases from 1990-2008, found that white men in the United States with 16 years or more of schooling had life expectancy at birth 14.2 years longer than African American males with fewer than 12 years of education. The gulf between well-educated white women and black women with low educational levels was 10.3 years.

The research study is published with the stark title, Differences in Life Expectancy Due to Race and Educational Differences Are Widening, and Many May Not Catch Up. It is the latest publication by a the MacArthur Foundation Research Network on an Aging Society, a roster of 15 leading academic experts in aging and longevity.

Low Education Shortens Life for All Groups

The report shows that lower educational levels marked declining life expectancy within every demographic group examined.

The gap between black women of high versus low educational levels was 6.5 years, and for Latinas the difference was 2.9 years. For males the longevity gaps were 12.9 years among whites, 9.7 years among blacks and 5.5 years for Hispanics.

Scientists decode "junk" DNA to show complex inner workings of genes

The 46 human chromosomes is where DNA resides. On Wednesday, scientists from around the world reported their findings on a nine-year project to study the 97 percent of the genome that's not, strictly speaking, made up of genes. (National Cancer Institute)

A colossal international effort has yielded the first comprehensive look at how our DNA works, an encyclopedia of information that will rewrite the textbooks and offer new insights into the biology of disease.

For one thing, the effort might help explain why complex diseases such as diabetes, high blood pressure and psychiatric disorders are so difficult to predict and, often, to treat.

The findings, reported Wednesday, reveal that the human genome is packed with at least 4 million on-off switches that tell our genes what to do and when. The switches reside in bits of DNA that once were dismissed as "junk" but turn out to play critical roles in controlling how cells, organs and other tissues behave.

The discovery, considered a major medical and scientific breakthrough, has enormous implications for human health because many complex diseases appear to be caused by tiny changes in hundreds of gene switches.

The findings are the fruit of an immense federal project, involving 440 scientists from 32 labs around the world. As they delved into the "junk" parts of the DNA that are not actual genes containing instructions for proteins they discovered it is not junk. At least 80 percent of it is active and needed.

The result is an annotated road map of much of this DNA, noting what it is doing and how. It includes the system of switches that, acting like dimmer switches for lights, control which genes are used in a cell and when they are used, and determine, for instance, whether a cell becomes a liver cell or a neuron.

The findings have applications for understanding how alterations in the non-gene parts of DNA contribute to disease, which might lead to new drugs.

They can also help explain how the environment can affect disease risk. In the case of identical twins, small changes in environmental exposure can slightly alter gene switches, with the result that one twin gets a disease and the other does not.

"It's Google maps," said Eric Lander, president and founding director of the Broad Institute of Harvard and the Massachusetts Institute of Technology.

DNA data unlocks map to genetic disease

A massive DNA database has generated a map of the genetic switches which impact everything from hair loss to cancer and opened the door to revolutionary treatments for a host of deadly diseases, researchers say.

'This is a major step toward understanding the wiring diagram of a human being,' said lead researcher Michael Snyder of Stanford University.

The Encyclopedia of DNA Elements - or ENCODE - has enabled scientists to assign specific biological functions for 80 per cent of the human genome and has helped explain how genetic variants affect a person's susceptibility to disease.

It also exposed previously hidden connections between seemingly unrelated diseases such as asthma, lupus and multiple sclerosis which were found to be linked to specific genetic regulatory codes for proteins that regulate the immune system.

A key insight revealed in a host of papers published in the journals Nature, Science and Cell is that many diseases result from changes in when, where and how a gene switches on or off rather than a change to the gene itself.

'Genes occupy only a tiny fraction of the genome, and most efforts to map the genetic causes of disease were frustrated by signals that pointed away from genes,' said co-author John Stamatoyannoupoulos, a researcher at the University of Washington.

'Now we know that these efforts were not in vain, and that the signals were in fact pointing to the genome's 'operating system.''

Another significant finding is that this blueprint of genetic switches can be used to pinpoint cell types that play a role in specific diseases without needing to understand how the disease actually works.

For instance, it took researchers decades to link a set of immune cells with the inflammatory bowel disease Crohn's. The ENCODE data was able to swiftly identify that the genetic variants associated with Crohn's were concentrated in that subset of cells.

This in-depth map of the human genetic code has also altered scientific understanding of how DNA works.

ENCODE project sheds light on human DNA and disease

When the human genome was sequenced a decade ago, scientists hailed the feat as a technical tour de force but they also knew it was just a start. The "HHA000078">DNA blueprint was finally laid bare, but no one knew what it all meant.

Now an international team has taken the crucial next step by delivering the first in-depth report on what the endless loops and lengths of DNA inside our cells are up to.

The findings, detailed Wednesday in more than two dozen reports in the journals Nature and Science and other publications, do much more than provide a straightforward list of genes. By creating a complicated catalog of all the places along our DNA strands that are biochemically active, they offer new insight into how genes work and influence common diseases. They also upend the conventional wisdom that most of our DNA serves no useful purpose.

Defining this hive of activity is essential, scientists said, because it transforms our picture of the human blueprint from a static list of 3 billion DNA building blocks into the dynamic master-regulator that it is. The revelations will be key to understanding how genes are controlled so that they leap into action at precisely the right time and place in our bodies, allowing a whole human being to develop from a single fertilized egg. In addition, they will help explain how the carefully choreographed process can go awry, triggering birth defects, diseases and aging.

"The human genome was a bit like getting 'War and Peace' in Russian: It's a great book containing all of human experience, but [if] I don't know any Russian it's very hard to read," said Ewan Birney, a computational biologist at the European Bioinformatics Institute in England who coordinated the analysis for the project. Now scientists are on their way to having the translation, he said.

More than 400 scientists have conducted upward of 1,600 experiments over five years to produce the Encyclopedia of DNA Elements, which goes by the nickname ENCODE. If graphically presented, the data it has generated so far would cover a poster 30 kilometers long and 16 meters high, Birney estimated.

Already, it is revealing surprises.

The results overturn old ideas that the bulk of DNA in our cells is useless albeit inoffensive junk just carried along for the evolutionary ride. Back in 2003, when the human genome was finished, scientists estimated that less than 2% carries instructions for making proteins, which become physical structures in our bodies and do the myriad jobs inside cells. The conventional wisdom was that the rest of the genetic code didn't do very much.

But the new analysis shows that more than 80% of the human genome is active in at least one biological process that the ENCODE team measured. Nearly all of it could turn out to be active when the data are more complete.

A huge chunk of that activity is wrapped up with gene regulation dictating whether the instructions each gene carries for making a unique protein will be executed or not. Such regulation is key, because pretty much every cell in the human body carries the entire set of 21,000 protein-making genes. To adopt its unique identity, each cell be it one in the pancreas that makes insulin or one in the skin making pigment or hair must activate only a subset of them.

Applied DNA Sciences Contracts With SMT for SigNature(R) DNA on Electronics

STONY BROOK, NY--(Marketwire -09/05/12)- Applied DNA Sciences, Inc. (APDN), (Twitter: @APDN), a provider of DNA-based anti-counterfeiting technology and product authentication solutions, announced today an agreement with SMT Corporation of Sandy Hook, Connecticut (SMT). SMT, the well known electronics parts distributor, will begin SigNature DNA marking components that leave its facility. The botanical SigNature DNA mark is designed to provide customers with the assurance that its parts were sourced at a known and respected distributor.

The agreement between APDN and SMT follows closely on the heels of the mandate by the Defense Logistics Agency that microcircuits supplied to DLA be SigNature DNA-marked. The mandate appeared at an announcement on the DLA Internet Bulletin Board System on August 7.

Tom Sharpe, Vice President of SMT, is a recognized thought-leader of the anti-counterfeiting efforts launched by government and industry. He testified this past November before the Senate Armed Services Committee regarding counterfeit electronic parts in the U.S. military supply chain. He has focused on mitigating the counterfeit threat in high reliability electronics, and established a leading inspection resource to restrict entry of counterfeit obsolete chips.

Mr. Sharpe pointed out that the agreement includes, but goes beyond, the parts supplied by SMT to the military. "Our defense and aerospace customers can now engage with assured provenance back to SMT at any points further downstream in the supply chain. The SigNature DNA mark will also assure customers and users downstream that the chips have undergone the rigorous testing and inspection applied by SMT on components before they leave our facility."

The agreement comes just as the new federal electronics anti-counterfeiting laws are due to come into effect. In Section 818 of the National Defense Authorization Act for Fiscal Year 2012, the Department of Defense must require suppliers of electronics parts to "monitor and eliminate" counterfeits from the military supply chain. A key milestone is due at the end of this month, when the DoD is instructed to write the new anti-counterfeiting wording into the DFARS (Defense Federal Acquisition Regulations Supplement, the main military procurement document). The APDN-SMT agreement is an effort toward early compliance with that law by an important player in the industry.

Sharpe stated: "We take great pride in stepping forward at the beginning of what promises to be a milestone in reducing counterfeit risk to the military and to private industry. We are determined to protect our warfighters by providing the highest reliability in materiel."

"I commend the unwavering diligence of the SMT Corporation in their systematic testing, and their first-to-market application of the SigNature DNA Provenance Mark," stated Janice Meraglia, Vice President, Government and Military Programs at APDN. "Tom Sharpe's willingness to take a proactive stand is in line with the integrity he and his team demonstrate on a daily basis."

President and CEO of Applied DNA Sciences, Dr. James A Hayward, called the agreement with SMT "a landmark step, and a model for the industry." Dr. Hayward pointed out that "Provenance Marking," as the company calls its program for SMT, combines with "Authentication Marking," as applied at electronic manufacturers to provide 360 degree, all-around coverage for the industry. Dr. Hayward added: "Together, they form an umbrella protection, which can provide assurance of originality from manufacturers when available, and assurance of provenance in other cases."

Iran hosts stem cell biology congress

Iran has held the 8th Congress on Stem Cell Biology and Technology, hosting scientists from nine countries in the capital city of Tehran, Press TV reports.

A group of fourteen scientists have participated in the event to discuss the importance of stem cell research and its ability to prevent genetic diseases.

Irans Royan Institute for Reproductive Biomedicine, Stem Cell Biology, and Technology is the countrys leading biomedical research center involved in stem cell technology and regenerative medicine.

Royan Institute researchers have used stem cell therapy to treat patients with cardiac arrest, chronic lower extremities ulcers, liver cirrhosis, and vitiligo.

They have also succeeded in cloning various farm animals, including a lamb named 'Royana', a goat named 'Hanna' and two calves called 'Bonyana' and 'Tamina'.

I think Iran has [made] quite a number of scientific contributions to both stem cell research and reproductive biomedicine and its a really good opportunity to be here and learn more about them, said Prof. Paul Tesar of the Case Western Reserve University, US.

Iran has also taken great strides in other scientific sectors including biotechnology, medical science and aerospace research.

Major advances in understanding the regulation and organization of the human genome

Public release date: 5-Sep-2012 [ | E-mail | Share ]

The National Human Genome Research Institute today announced the results of a five-year international study of the regulation and organization of the human genome. The project is named ENCODE, which stands for the Encyclopedia of DNA Elements. In conjunction with the release of those results, the Journal of Biological Chemistry has published a series of reviews that focus on several aspects of the findings.

"The ENCODE project not only generated an enormous body of data about our genome, but it also analyzed many issues to better understand how the genome functions in different types of cells. These insights from integrative analyses are really stories about how molecular machines interact with each other and work on DNA to produce the proteins and RNAs needed for each cell to function within our bodies," explains Ross Hardison of Pennsylvania State University, one of the JBC authors.

Hardison continued: "The Journal of Biological Chemistry recognized that the results from the ENCODE project also would catalyze much new research from biochemists and molecular biologists around the world. Hence, the journal commissioned these articles not only to communicate the insights from the papers now being published but also to stimulate more research in the broader community."

The human genome consists of about 3 billion DNA base pairs, but only a small percentage of DNA actually codes for proteins. The roles and functions of the remaining genetic information were unclear to scientists and even referred to as "junk DNA." But the results of the ENCODE project is filling this knowledge gap. The findings revealed that more than 80 percent of the human genome is associated with biological function.

The study showed in a comprehensive way that proteins switch genes on and off regularly and can do so at distances far from the genes they regulate and it determined sites on chromosomes that interact, the locations where chemical modifications to DNA can influence gene expression, and how the functional forms of RNA can regulate the expression of genetic information.

The results establish the ways in which genetic information is controlled and expressed in specific cell types and distinguish particular regulatory regions that may contribute to diseases.

"The deeper knowledge of gene regulation coming from the ENCODE project will have a positive impact on medical science," Hardison emphasizes. For example, recent genetic studies have revealed many genomic locations that can affect a person's susceptibility to common diseases. The ENCODE data show that many of these regions are involved in gene regulation, and the data provide hypotheses for how variations in these regions can affect disease susceptibility, adds Hardison.

The effort behind the ENCODE project was extraordinary. More than 440 scientists in 32 labs in United States, the United Kingdom, Spain, Singapore and Japan performed more than 1,600 sets of experiments on 147 types of tissue. The results were published today in one main integrative paper and five other papers in the journal Nature, 18 papers in Genome Research and six papers in Genome Biology.
