biochemical pathway

(Scripps Research Institute) A Scripps Research team has unraveled a new biochemical pathway that triggers a critical repair response to correct errors in the DNA replication process that could otherwise lead to harmful or fatal mutations in cells.

Though the work focused on yeast cells, the team expects to find an analogous system in human cells that could be exploited as a target for potential therapies for cancers, which are often caused by such repair mechanisms going off course.

(Duke University Medical Center) Researchers at Duke University Medical Center have published a study in Science that provides compelling evidence that the nitric oxide system in cells is very broad-based and important, resembling in its essence the much-studied system of phosphorylation.

The findings may offer new insights into how cells work and the basis of many diseases.

Scientists have developed a new type of enzyme inhibitor capable of blocking a biochemical pathway that plays a key role in cancer development.

Based on studies in human melanoma cells, the research paves the way for developing new ways to treat cancer by dampening overactive enzyme activity that leads to uncontrolled tumor growth.

The study shows how small-molecule inhibitors can be designed to target a family of signaling proteins, called phosphatidyl-inositol-3-kinases, or PI3Ks.

A newly defined biochemical pathway in plants may provide the scientific tools to design plants that will yield larger quantities of alternative transportation fuels than currently can be produced, according to researchers.
