Researchers have learned how living beings can keep gene expression in check -- which might partly explain the uncontrolled gene expression found in many cancers. "Using yeast as a model organism, we ...

Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene ...

In a collaborative study published Feb. 9, 2009, in the Proceedings of the National Academy of Sciences (PNAS), scientists performed a genome-wide expression analysis comparing highly enriched normal ...

A group of scientists has uncovered a previously unknown way that our genes are made into reality. Rather than directions going one-way from DNA to RNA to proteins, the latest study shows that RNA ...
