No junk: Long RNA mimics DNA, restrains hormone responses

It arises from what scientists previously described as "junk DNA" or "the dark matter of the genome," but this gene is definitely not junk. The gene GAS5 acts as a brake on steroid hormone receptors, making it a key player in diseases such as hormone-sensitive prostate and breast cancer. read more

Splitting the Junk DNA Difference

A big dispute erupted in the genomics world in 2012 with the publication of the ENCODE consortium's data - and with their interpretation of it. How much of the human genome is functional? And just what does "functional" mean? The ENCODE...Show More Summary

Penn Team Finds Ovarian Cancer Oncogene in "Junk DNA"

A team has mined genomic sequences sequences to identify a non-protein-coding RNA whose expression is linked to ovarian cancer.

Penn team finds ovarian cancer oncogene in 'junk DNA'

PHILADELPHIA - 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. read more

More than 90% of Human DNA Is Useless 'Junk,' Study Finds

More than a decade has passed since the completion of the Human Genome Project, the international collaboration to map all of the "letters" in our DNA. The huge effort led to revolutionary genomic discoveries, but more than 10 yearsShow More Summary

Over 90% Of Human DNA May Be Completely Worthless

5 months agoGenres / Sci Fi : io9

Geneticists at Oxford University are making the astounding claim that a mere 8.2% of our DNA does something biologically important. That means upwards of 90% of the human genome is "junk" — a discovery that could dramatically hasten genetic research. Read more...

DNA mostly 'junk?' Only 8.2 percent of human DNA is 'functional', study finds

Only 8.2 percent of human DNA is likely to be doing something important -- is 'functional' -- say researchers. This figure is very different from one given in 2012, when some scientists involved in the ENCODE (Encyclopedia of DNA Elements) project stated that 80% of our genome has some biochemical function.

#PLOSGenetics: The Case for Junk DNA

7 months agoAcademics : Pharyngula

This is the paper to read: Palazzo & Gregory’s The Case for Junk DNA. It clearly and logically lays out the complete argument from evidence and theory for the thesis that most of the genome is junk. It’s not revolutionary or radical, though: the whole story is based on very fundamental population genetics and molecular…

News Of Junk DNA's Death Has Been Greatly Exaggerated

8 months agoGenres / Sci Fi : io9

The term "junk DNA" has been under attack lately, but a pair of geneticists are now making the case for this much maligned and misunderstood concept. There are significant chunks of our DNA, they argue, that really are utterly useless. Read more...

Genome regions once mislabeled 'junk' linked to heart failure

Large sections of the genome that were once referred to as 'junk' DNA have been linked to human heart failure, according to research. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn't code for proteins. Show More Summary

Genome regions once mislabeled 'junk' linked to heart failure

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. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn't code for proteins. Show More Summary

Pseudogenes Are Not Junk DNA

In 2007, a PLoS ONE paper by Ahmed et al. proposed a phylogeny for Mycobacteria in which M. leprae (the leprosy organism) is shown as a relatively recent branch off a very long tree, with M. tuberculosis depicted (in a decidedly fanciful schematic) as being of relatively recent provenance (35,000 years), diverging from M.

Non-coding DNA may affect type 2 diabetes risk

11 months agoHealth : Medical News Today

Once thought of as "junk" DNA because it does not contain genes that encode proteins, scientists are starting to discover non-coding DNA can nevertheless influence the effect of coding DNA, such as switching genes on and off.Now, a new...Show More Summary

Non-coding DNA implicated in type 2 diabetes

Variations in non-coding sections of the genome might be important contributors to type 2 diabetes risk, according to a new study. DNA sequences that don't encode proteins were once dismissed as "junk DNA", but scientists are increasingly...Show More Summary

Jumping DNA in the brain may be a cause of schizophrenia

12 months agoHealth : Medical News Today

Stretches of DNA called retrotransposons, often dubbed "junk DNA", might play an important role in schizophrenia. In a study published today in the journal Neuron, a Japanese team revealed that LINE-1 retrotransposons are abnormallyShow More Summary

Jumping DNA in brain may be cause of schizophrenia

Stretches of DNA called retrotransposons, often dubbed “junk DNA”, might play an important role in schizophrenia. In a study published, a Japanese team revealed that LINE-1 retrotransposons are abnormally abundant in the schizophrenia brain, modify the expression of genes related to schizophrenia during brain development, and may be one of the causes of schizophrenia. 

Causes of Cancer Likely Found in ‘JunkDNA, Study Says

Even as whole-genome sequencing has become much cheaper, genetic research has continued to focus on the exome, or the tiny fraction of human DNA that codes the proteins that make up our physical structures. But according to a recentShow More Summary
