Junk DNA News and Research

RSS

In genetics, "junk DNA" or noncoding DNA describes components of an organism's DNA sequences that do not encode for protein sequences.

Non-coding RNA gives off biological signals during viral infection

Once considered unimportant "junk DNA," scientists have learned that non-coding RNA (ncRNA) - RNA molecules that do not translate into proteins - play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer's disease.

UCSF scientists assemble high-value genetic resource to help researchers

One of the ultimate ways of understanding what impact any particular gene has in human health or disease is to disrupt it-knocking it down or wiping it out in a worm, fly or mouse and gauging what happens next. Now scientists at the University of California, San Francisco (UCSF) Diabetes Center and the Gladstone Institute for Cardiovascular Disease have assembled a large publicly available resource to help researchers determine the importance of genes in mice and better gauge what roles they might play in disease.

Researchers identify new mechanism by which colon cancer develops

A team of researchers at Case Western Reserve University School of Medicine have identified a new mechanism by which colon cancer develops. By focusing on segments of DNA located between genes, or so-called "junk DNA," the team has discovered a set of master switches, i.e., gene enhancer elements, that turn "on and off" key genes whose altered expression is defining for colon cancers.

Two CNVs may increase risk of aggressive prostate cancer

An international research team led by Weill Cornell Medical College investigators have discovered two inherited-genetic deletions in the human genome linked to development of aggressive prostate cancer.

Researchers discover MicroRNAs as new switch of adipose cell development

Hunger has always threatened mankind. This makes it unsurprising that human bodies attempt to store all surplus nourishment in adipose tissue. In developed countries, this life-saving craving is turning into a problem and obesity—adiposity—is turning into a danger. Why, though, does excess fat the body ill? How does fat trigger diabetes? And can these superfluous fat reserves be turned into warmth and just as well burnt?

MDC researcher receives ERC grant for transposon study

Dr. Zsuzsanna Izsv-k, research group leader at the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch, has been named recipient of a European Research Council (ERC Advanced) grant worth EUR 1.94 million for her research on "jumping genes."

RaNA Therapeutics completes $20.7 million round of financing

RaNA Therapeutics, Inc. today announced it has completed a $20.7 million round of financing co-led by Atlas Venture, SR One, and Monsanto, with participation of Partners Innovation Fund. The company is developing a technology platform to enable selective activation of target genes and expression of therapeutic factors by targeting a type of regulatory RNA called long non-coding RNA.

Researchers can reverse aging process for human adult stem cells

Researchers have shown they can reverse the aging process for human adult stem cells, which are responsible for helping old or damaged tissues regenerate.

New book on the myth of junk DNA

Forty years ago scientists discovered that more than 95% of our DNA does not encode proteins. Since then the non-protein-coding portion was labeled "junk" and attributed to molecular accidents that have accumulated in the course of evolution.

Viruses that are natural part of human genome may retrovirus culprit

A retrovirus that inserted itself into the human genome thousands of years ago may be responsible for some cases of the neurodegenerative disease amyotrophic lateral sclerosis (ALS), also known as Lou Gherig’s disease. The finding, made by Johns Hopkins scientists, may eventually give researchers a new way to attack this universally fatal condition.

Researchers discover molecular mechanism implicated in geographic atrophy

A team of researchers, led by University of Kentucky ophthalmologist Dr. Jayakrishna Ambati, has discovered a molecular mechanism implicated in geographic atrophy, the major cause of untreatable blindness in the industrialized world.

Five young scientists receive Damon Runyon-Rachleff Innovation Award for cancer research

The Damon Runyon Cancer Research Foundation announced that five scientists with novel approaches to fighting cancer have been named 2011 recipients of the Damon Runyon-Rachleff Innovation Award. The grant of $450,000 over three years is awarded each year to early career scientists whose projects have the potential to significantly impact the prevention, diagnosis and treatment of cancer.

Genetic biomarker linked to increased risk for breast cancer found in 'junk' DNA

A new genetic biomarker that indicates an increased risk for developing breast cancer can be found in an individual's "junk" (non-coding) DNA, according to a new study featuring work from researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues.

Researchers document novel form of splicing in nerve cell cytoplasm

Cells have their own version of the cut-and-paste editing function called splicing. Researchers at the University of Pennsylvania School of Medicine have documented a novel form of splicing in the cytoplasm of a nerve cell, which dictates a special form of a potassium channel protein in the outer membrane.

Scientists discover way of shrinking tumours in cancers

Australian and American scientists have found a way of shrinking tumours in certain cancers - a finding that provides hope for new treatments.

Scientists discover genetic flaw that causes facioscapulohumeral muscular dystrophy

Nearly two decades after they identified the specific genetic flaw that causes a common type of muscular dystrophy, scientists believe they have figured out how that flaw brings about the disease. The finding by an international team of researchers settles a longstanding question about the roots of facioscapulohumeral muscular dystrophy or FSHD.

GWA Study helps scientists identify genetic variant that increases tuberculosis susceptibility in African populations

Scientists have identified a genetic variant which increases susceptibility to tuberculosis (TB) in African populations using a technique known as a genome-wide association (GWA) study. This is the first novel disease variant to be identified using this technique in Africans and demonstrates that such studies are viable in African populations, which have a high degree of genetic diversity.
