The hepatitis C virus (HCV) has a previously unrecognized tactic to outwit antiviral responses
and sustain a long-term infection. It also turns out that some people are genetically equipped with
a strong countermeasure to the virus' attempt to weaken the

Proteins are made up of a chain of amino acids and are vital for all cell processes. Proteases are
among the most important types of protein. Like "molecular scissors", they cut other proteins at
given positions and thereby execute important cell function
Researchers at Brigham and Women's Hospital (BWH) and Carnegie Mellon University have

NYU Langone Medical Center researchers have found a biological weakness in the workings of
the most commonly mutated gene involved in human cancers, known as mutant K-Ras, which
they say can be exploited by drug chemotherapies to thwart tumor growth.
