Blocking an oncogene in liver cancer could be potential therapy option
Scientists have found that a synthetic molecule they designed can block activation of a gene in liver cancer cells, halting a process that allows some of those cancer cells to survive chemotherapy.

Blocking tumor's 'death switch' paradoxically stops tumor growth
Every cell contains machinery for self-destruction, used to induce death when damaged or sick. But according to a new research study, a receptor thought to mediate cell suicide in normal cells may actually be responsible ...

New stem cell line provides safe, prolific source for disease modeling and transplant studies
Researchers have generated a new type of human stem cell that can develop into numerous types of specialized cells, including functioning pancreatic beta cells that produce insulin. Called endodermal progenitor (EP) cells, ...

A surprising molecular switch: Lipids help control the development of cell polarity
In a standard biology textbook, cells tend to look more or less the same from all sides. But in real life cells have fronts and backs, tops and bottoms, and they orient many of their structures according to ...

Molecules work the day shift to protect the liver from accumulating fat (w/ Video)
The liver normally makes and stores fat, which is required in moderation for normal body function. However, if the process goes awry, excess fat in the liver can cause major liver damage. In fact, fatty liver ...
