Junk DNA Vital Biological Role
2013-06-27 08:25:25

Rebekah Eliason for redOrbit.com - Your Universe Online At the center of most human cells, genomic DNA lies tucked away within a nucleus. However, a surprisingly small percentage of this DNA actually codes for genes that can be translated into proteins. In fact, some researchers estimate as much as 98 percent of this DNA seems to have a puzzling lack of purpose, leading many to refer to it as 'junk DNA.' However, a new study from UC San Francisco now emphasizes the potentially important...

The Optical Society New plug-in optical sensor could be used for in-the-field diagnosis of Kaposi's sarcoma, a cancer linked to AIDS As antiretroviral drugs that treat HIV have become more commonplace, the incidence of Kaposi's sarcoma, a type of cancer linked to AIDS, has decreased in the United States. The disease, however, remains prevalent in sub-Saharan Africa, where poor access to medical care and lab tests only compound the problem. Now, Cornell University engineers have created...

Research uncovers a virus which infects a host that has a non-standard nuclear genetic code Among eukaryotes with modified nuclear genetic codes, viruses are unknown. Until now it had been believed that the modifications to the genetic code effectively prevented new viral infections. However, researchers have now reported the first example of a virus that can be shown to have crossed the boundary from organisms using the standard genetic code to those with an alternate genetic code....

Studies suggest new approach to treating HIV A team of researchers based at Johns Hopkins has decoded a system that makes certain types of immune cells impervious to HIV infection. The system's two vital components are high levels of a molecule that becomes embedded in viral DNA like a code written in invisible ink, and an enzyme that, when it reads the code, switches from repairing the DNA to chopping it up into unusable pieces. The researchers, who report the find in the Jan. 21 early...

Little Brown Bats Found To Have A Rare Active Jumping Gene
2013-01-04 07:37:34

April Flowers for redOrbit.com - Your Universe Online Jumping genes, or transposable elements, are strange rogue sequences from which most of our DNA can be traced, but are largely idle in mammals. Johns Hopkins researchers report, however, that they have identified a new DNA sequence moving around in bats. This is the first member of the transposable elements class found to be active in mammals. The findings of this study, published online at the Proceedings of the National Academy of...

Using computational techniques, researchers have shown how a protein responsible for the maturation of the virus releases itself to initiate infection Bioinformaticians at IMIM (Hospital del Mar Medical Research Institute) and UPF (Pompeu Fabra University) have used molecular simulation techniques to explain a specific step in the maturation of the HIV virions, i.e., how newly formed inert virus particles become infectious, which is essential in understanding how the virus replicates....

HIV-1 is a genetically diverse collection of viruses, making it a moving target in vaccine development. In a study published in the Journal of Clinical Investigation, researchers led by Brad Jones at the University of Toronto in investigated the feasibility of eliminating HIV-infected cells by targeting cellular immune responses against a human endogenous retrovirus (HERV). HERVs are the DNA remnants of ancient infectious retroviruses that became part of the germ line cells of our ancestors....

Drug resistance is a major problem when treating infections. This problem is multiplied when the infection, like HIV-1, is chronic. New research published in BioMed Central's open access journal Retrovirology has examined the genetic footprint that drug resistance causes in HIV and found compensatory polymorphisms that help the resistant virus to survive. Currently the strategy used to treat HIV-1 infection is to prevent viral replication, measured by the number of viral particles in the...

Footprint Of A Fly Virus Found In Fly DNA

The discovery of virus-like genes in the DNA of a commonly studied fruit fly could enable research on whether animals hijack viral genes as an anti-viral defense In a curious evolutionary twist, several species of a commonly studied fruit fly appear to have incorporated genetic material from a virus into their genomes, according to new research by University at Buffalo biologists. The study found that several types of fruit fly -- scientific name Drosophila -- harbored genes similar to...

A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. Frederic D. Bushman, PhD, professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania, led a study published this month in the Proceedings of the National Academy of Sciences that sequenced the DNA of viruses -- the virome -- present...
