Viral Relics Reveal Cancers Footprint On Our Evolution

Viral Relics Reveal Cancer's 'Footprint' On Our Evolution

University of Oxford Cancer has left its ‘footprint’ on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species. Viral relics are evidence of the ancient...

Temple University Health System Their approach promises a permanent cure and potential for protection against HIV The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good. "This is one important step on the path...

Professor Mark Wainberg from McGill University in Montreal shows that Dolutegravir rarely selects for resistance mutations and when they occur, HIV growth is impaired. Toulon, Var, France (PRWEB) May 28, 2014 Professor Mark Wainberg stated at the ISHEID that "Dolutegravir resistance is very difficult to obtain in vitro" and that this situation is unique among other antiretrovirals. A New Mechanism of Resistance Selection Actually, Dolutegravir is the last approved integrase...

Enzyme's double-edged sword may soon be sheathed Johns Hopkins biochemists have figured out what is needed to activate and sustain the virus-fighting activity of an enzyme found in CD4+ T cells, the human immune cells infected by HIV. The discovery could launch a more effective strategy for preventing the spread of HIV in the body with drugs targeting this enzyme, they say. A summary of their work was published online on April 21 in the journal Proceedings of the National Academy of...

Retroviruses are important pathogens capable of crossing species barriers to infect new hosts, but knowledge of their evolutionary history is limited. By mapping endogenous retroviruses (ERVs), retroviruses whose genes have become part of the host organism's genome, researchers at Uppsala University, Sweden, can now provide unique insights into the evolutionary relationships of retroviruses and their host species. The findings will be published in a coming issue of Proceedings of the National...

HIV Virus Hideout Complicates Cure

[ Watch The Video: Barrier To HIV Cure Bigger Than Previously Thought ] redOrbit Staff & Wire Reports - Your Universe Online Although current treatments for human immunodeficiency virus (HIV) can keep the disease at bay, a larger-than-expected amount of hidden virus may complicate efforts to find a cure, according to the most detailed and comprehensive analysis to date of the latent reservoir of HIV proviruses. The three-year study, published Thursday in the journal Cell, deals a...

Discovery offers hope of new, shorter HIV treatment if drugs are started right away Scientists have discovered a critical new clue about why some people are able to control the HIV virus long term without taking antiviral drugs. The finding may be useful in shortening drug treatment for everyone else with HIV. These rare individuals who do not require medicine have an extra helping of a certain type of immune protein that blocks HIV from spreading within the body by turning it into an...

New Retrovirus Discovered In Dead Polar Bear At Berlin Zoo

Lee Rannals for redOrbit.com - Your Universe Online A polar bear that died at the Berlin Zoo was suffering from a virus that caused acute inflammation of the brain, according to research published in the journal Virology. Knut died unexpectedly in 2011 at the age of four while in his enclosure. Caretakers at the zoo were shocked to find their superstar polar bear had died, especially since polar bears can live in captivity for 35 years. Researchers analyzed the genetic material of...

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...
