Alzheimer's alarm over anesthetics

Recent test tube and animal experiments suggest that certain general anaesthetics could increase the risk of developing Alzheimer's disease and other memory problems in elderly patients. The studies also highlight the need for more careful recording of anaesthetic combinations and doses to assess potential risks.

Viral oncoprotein inactivation of p53

A team of scientists led by Dr. Xiaojiang Chen have uncovered the molecular mechanism behind how a viral oncoprotein inactivates p53. The study reveals that the viral protein binds to p53, causing a conformational change that prevents it from binding to DNA and thus abolishes its tumor-suppressing function.

Plant protection from cold decoded

Plant biologist Jian Kang Zhu discovered that the high expression of osmotically responsive gene 1 (HOS1) acts as a biochemical gate to cut off the plant's cold protection. The HOS1 protein interacts with ICE1, kicking off a genetic cascade that provides cold protection proteins.

Partner proteins may help estrogen foster breast cancer

Researchers at Ohio State University identified seven partner proteins that interact with estrogen to activate or suppress genes in breast cancer cells. The study suggests that c-MYC is one of these activating partner proteins, which could lead to new drug targets and improved treatment options for hormone-resistant tumors.
