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.

'Junk' DNA suppresses breast cancer

Supposed "junk" DNA, found in between genes, plays a role in suppressing cancer, according to new research by Universities of Bath and Cambridge.

Study points to future treatment for post-stroke damage

A study of rats released today shows that blocking a type of RNA produced by what used to be called "junk DNA" can prevent a significant portion of the neural destruction that follows a stroke. The research points toward a future treatment for post-stroke damage, which is often more extensive than the initial destruction that results when blood to the brain is temporarily shut off.

Nuclear membrane fixes potentially fatal breaks in DNA strands

Scientists have found a new function of the nuclear membrane, the envelope that encases and protects DNA in the nucleus of a cell - it fixes potentially fatal breaks in DNA strands.

Four microRNAs appear to play critical roles in controlling cholesterol, triglyceride metabolism

Four tiny segments of RNA appear to play critical roles in controlling cholesterol and triglyceride metabolism. In their report receiving advance online publication in Nature Medicine, a Massachusetts General Hospital-based research team describes finding how these microRNAs could reduce the expression of proteins playing key roles in the generation of beneficial HDL cholesterol, the disposal of artery-clogging LDL cholesterol, control of triglyceride levels and other risk factors of cardiovascular disease.

Study suggests link between human endogenous retroviral genes and ALS

Scientists at the National Institutes of Health discovered that reactivation of ancient viral genes embedded in the human genome may cause the destruction of neurons in some forms of amyotrophic lateral sclerosis (ALS).

Scientists map genes responsible for early embryonic development in humans

An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, which is being published in the journal Nature Communications, provides an in-depth understanding of early embryonic development in human - and scientists now hope that the results will help finding for example new therapies against infertility.

Discovery may lead to new ways to diagnose, treat brain cancer

Researchers at the Virginia Bioinformatics Institute have uncovered a link between the genomes of cells originating in the neural crest and development of tumors — a discovery that could lead to new ways to diagnose and treat cancer.

Research: Critical aspects of human genome's regulatory program encoded by genomic sequence elements

Since the classical studies of Jacob and Monod in the early 1960s, it has been evident that genome sequences contain not only blueprints for genes and the proteins that they encode, but also the instructions for a coordinated regulatory program that governs when, where and to what extent these genes and proteins are expressed.

Study helps solve mystery about how genetic variations can increase cancer risk

Single-letter genetic variations within parts of the genome once dismissed as 'junk DNA' can increase cancer risk through wormhole-like effects on far-off genes, new research shows.

Researchers obtain detailed picture of how Gas5 RNA interacts with steroid hormone receptors

It arises from what scientists previously described as "junk DNA" or "the dark matter of the genome," but this gene is definitely not junk.

Researchers identify non-protein-coding RNA whose expression linked to ovarian cancer

Over the years researchers have made tremendous strides in the understanding and treatment of cancer by searching genomes for links between genetic alterations and disease.

Researchers identify possible new drug target for treating childhood blood cancer

In what is believed to be the largest genetic analysis of what triggers and propels progression of tumor growth in a common childhood blood cancer, researchers at NYU Langone Medical Center report that they have identified a possible new drug target for treating the disease.

University of Michigan scientists uncover how cells block mutation-causing activity of junk DNA

There's a civil war going on inside every one of the 37 trillion cells in your body. Now, University of Michigan scientists have uncovered how your cells keep this war from causing too much collateral damage.

Junk DNA linked to heart failure, reveals Washington University study

Large sections of the genome that were once referred to as "junk" DNA have been linked to human heart failure, according to research from Washington University School of Medicine in St. Louis.

Researchers demonstrate accurate identification of amino acids

Some three billion base pairs make up the human genome-the floor plan of life. In 2003, the Human Genome Project announced the successful decryption of this code, a tour de force that continues to supply a stream of insights relevant to human health and disease.

Supercomputer dramatically accelerates genome analysis

Although the time and cost of sequencing an entire human genome has plummeted, analyzing the resulting three billion base pairs of genetic information from a single genome can take many months.

Study: Variations in non-coding sections of genome might be main contributors to type 2 diabetes risk

Variations in non-coding sections of the genome might be important contributors to type 2 diabetes risk, according to a new study.

Cyclin D1 protein controls cell cycle progression, microRNA biogenesis in breast cancer

Cyclin D1, a protein that helps push a replicating cell through the cell cycle also mediates the processing and generation of mature microRNA, according to new research publishing November 29 in Nature Communications. The research suggests that a protein strongly implicated in human cancer also governs the non-protein-coding genome. The non-coding genome, previously referred to as junk DNA, makes up most of the human genome, and unlike the coding genome, varies greatly between species.

Close to 100 novel human gene regions that code for proteins may be linked to cancer

By using a new analysis method, researchers at Karolinska Institutet and Science for Life Laboratory (SciLifeLab) in Sweden have found close to one hundred novel human gene regions that code for proteins. A number of these regions are so-called pseudogenes, which may be linked to cancer.

Study uncovers novel mechanism that helps govern regulated gene expression

A study led by researchers at the University of California, San Diego School of Medicine shines a new light on molecular tools our cells use to govern regulated gene expression. The study was published on line in advance of print November 10 in the journal Nature Structural and Molecular Biology.
