Sentences with phrase «suppressor protein»
A suppressor protein refers to a type of protein that helps regulate or control the growth and division of cells in our body. It acts like a "brake" by preventing cells from growing or dividing too quickly, which could lead to uncontrolled cell growth and potentially contribute to the development of diseases like cancer. It helps maintain a balance and keeps our cells in check. Full definition
Dr. Shawn Li, PhD, and his team at Western's Schulich School of Medicine & Dentistry, identified that a protein called Numb functions to promote the death of cancer cells by binding to and stabilizing a tumor suppressor protein called p53 - a master regulator of cell death.

In their research on young mice, for instance, all the subjects died when they were infected with the Nodamura virus, but when Ding's researchers removed the suppressor protein called B2 from the virus, the infected mice began producing huge armies of the virus - attacking siRNAs and lived, unaffected by the otherwise lethal infection.
Remove the suppressor protein from the virus, Ding's research discovered, and the subject's body will quickly eliminate the virus using the RNAi process, which sends out small interfering RNAs (siRNAs) to kill the disease.
