Molecule aids fight E. Coli Infections

...enetically engineered a group of Drosophila with a mutated version of PGRP-LC. Indeed, these flies were much more susceptible to E. coli infection than were their normal counterparts, the researchers observed. "The next question to ask is whether this protein plays a related role in humans. Understanding th...

Gene enchances radiation therapy - A novel approach to fight cancer

...iversity of Michigan at Ann Arbor stated that such mutated gene therapy causing radiation boosting effects targeted against growth factor receptors offers an exciting potential advance in cancer treatment. This type of approach "offers the potential for a dramatic improvement in the outcome of treatment that...

Possibility Of Treatment For Permanent Hearing Loss

...encing technique, the researchers had introduced a mutated gene that causes deafness in humans into the inner ear of mice. This gene acted through a dominant negative mechanism, and the mice had moderate hearing loss. Then they had simultaneously introduced the mutant gene and a short piece of interfering RN...

Influenza Avian Flu strain has become more contagious and dangerous.

The Influenza avian flu strain - H5N1 has mutated since 2002 to become more dangerous //and increases the risk of causing a pandemic disease. The Asian strain H5N1 influenza virus has changed its characters since 2002, as the virus has become less deadly to ducks; the virus multiplies in the ducks...

Scientists Unveil Mechanism Behind Resistance to Severe Malaria

...s week in the journal Nature. Nature has probably mutated the hemoglobin gene to protect the people from malaria in endemic regions. Hemoglobin exists in several varieties. Hemoglobin A is the most common, but in parts of West Africa, where malaria is rife, one-fourth of the population has at least one gene...
