The activation of Protein Kinase A (PKA) is a critical part in how the body responds to stress and starvation. Using a variety of imaging and biochemical techniques, a team of researchers has revealed ...

In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes. This marked the discovery of microRNAs ...

Protein-protein interaction is a key concept in the fields of signal transduction and gene regulation. Investigators can make educated guesses as to whether two proteins actually interact, but ...

Cancer originates at the genetic micro-molecular level within a cell — resulting in a cascade of subtle biochemical and cellular abnormalities that escape internal patrol — and eventually manifests as ...
