These sequences have also been found in proteins from some other cancer-causing viruses such as Epstein Barr virus and Kaposi's sarcoma virus, but what role this sequence plays in cancer developm...

Molecular biology fills gaps in knowledge of bat evolution

...n that is now North America. This latest research helps fill gaps in the evolutionary history of one of the most diverse group of mammals on earth and the only mammals capable of powered flight. The fossil record alone left bat evolutionary history about 61 percent incomplete, according to Springer. Bats ...

Lack of enzyme turns fat cells into fat burners

...2 diabetes."This adds another tissue or organ that helps out in the process ofenergy maintenance," said Wakil. "ACC2 is potentially a key enzyme inthe regulation of weight, obesity, and related problems."Wakil and his colleagues studied the oxidation of fatty acid andglucose in cultures of fat cells isolat...

Research advances quest for HIV-1 vaccine

...the critical features of 4E10 recognition of HIV-1 helps to define potential immunogens able to elicit 4E10-like antibodies. This is an excellent example of the tremendous potential for accelerating HIV vaccine design when scientists from multidisciplinary laboratories come together to tackle a major scien...

U-M scientist to talk about tissue engineering at AAAS

...o badly to simply heal on its own. A tiny scaffold helps direct the engineered cells to the right place, then dissolves once the cells begin to generate to fill in the wound. "In certain kinds of defects, the body cannot heal itself and the body needs a jumpstart," Krebsbach said. To heal a large wound, l...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

...how one key player -- a protein called clathrin -- helps regulate endocytosis like a well-oiled machine. It may also give us insights into the kinds of disease states that can happen when clathrin-regulated endocytosis goes wrong. The findings, already published online, will appear in the April print edit...

For any given disease, such as type II diabetes or coronary artery disease, researchers can use the HapMap to compare the genetic variation patterns of a group of peopl...

Antibiotic might fight HIV-induced neurological problems

...ion known as encephalitis. The other protein, p38, helps trigger a series of events that result in a cell's programmed death, called apoptosis. Only one of the five treated monkeys showed any signs of encephalitis, and that monkey's condition was deemed mild by a set of standard measures. After the same a...

Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

...purs an immune response without live bacteria, LPS helps to reveal how the immune system works on its own, without the complication of side effects. The team found that E. coli-infected pups later injected with LPS had significantly lower concentrations of cytokines called interleukins than control pups (...

Pulsating ultrasound enhances gene therapy for tumors

... Pulsed-HIFU instead renders tissues permeable and helps target them for taking up genes and other therapeutic substances injected into the body. "Basically, we're using sound waves to open up the tissue by producing gaps between the cells, making it leakier and more prone to taking up various genes, agen...
