Study finds more than one-third of human genome regulated by RNA

... class of molecule once relegated to the sidelines may be one of theprincipal players in regulating cellular mechanisms. "It's exciting to see how many genes are regulated by microRNAs. We nowknow that this type of gene control is much more widespread thanpreviously appreciated," says Whitehead Member a...

Live Recombinant Adenovirus Vaccine Technique Explored

...ombinant HPV vaccines currently in clinical trials may not be ideal in poorer countries because they are expensive and require multiple immunizations. The Hopkins researchers developed their vaccine prototype using canine oral papillomavirus (COPV), which behaves similarly to HPV. Research by other scie...

Emory Eye Center Implants Its First Retinal Chips In Patients With Retinitis Pigmentosa

...anned for mid-February. "This experimental device may make it possible for those with retinitis pigmentosa to have a much better quality of life," says Dr. Aaberg. "We are excited to be able to participate in this clinical trial as part of Emory Eye Center's ongoing research and surgical procedures to f...

Gene therapy converts dead bone graft to new, living tissue

...cess calcium. In an average year, a healthy person may remove and rebuild 10 percent of his or her bone structure. This process of teardown and rebuilding is triggered in the dead bone when Schwarz paints it with the genetically modified virus. New blood vessels begin to grow around and into the bone sp...

Molecular machine may lead to new drugs to combat human diseases

...s previously believed to have no function actually may play specialized roles in cell behavior. While humans have introns, they don't have Group I introns. Many pathogens that cause human diseases, however, do have Group I introns, including the HIV opportunistic infections pneumocystis, a form of pneum...

Yale Scientists Find MicroRNA Regulates Ras Cancer Gene

...d Slack, "after diagnosis, gene therapy with let-7 may be a way to alleviate or slow it down." This work arose from Slack's basic research in the department of molecular, cellular and developmental biology on the nematode round worms, C. elegans. He found that these worms require let-7 RNA for normal de...

The researchers believe the findings may bolster the “Out-of-Africa?hypothesis that suggests we all trace to an ancient line that first evolved in Africa and then displaced other hominids as recently as 50,000 years ago.
