Key Signaling Protein Structure Reveals Clues to Alzheimer’s disease therapy
The protein gamma-secretase appeared to be a promising target for drugs to treat Alzheimer’s disease. It “cuts” the amyloid precursor protein to release amyloid-beta — a protein fragment that clumps together and forms neuron-killing plaques. “Amyloid-beta is thought to ‘seed’ Alzheimer’s disease, so lowering its production has been a goal to… Read MoreApr. 27, 2017

Polarity protein role in cell survival
Cell survival is dependent upon regulation of numerous proteins, both cytosolic and membrane bound. Reporting in Nature Communications, Mukhtar Ahmed, Ph.D., and Ian Macara, Ph.D., identified an unexpected link between cell survival and the polarized delivery of proteins to the surface of mammary epithelial cells.

Fighting fungal infections
The fungal pathogen Candida albicans causes diseases ranging from topical infections such as athlete’s foot and oral thrush to life-threatening systemic infections. Increasing incidence of infections and drug resistance support the need for new therapeutics. Now, Galina Lepesheva, Ph.D., and colleagues report the catalytic properties, ligand-binding profiles and inhibition of activity of C. albicans CYP51 by… Read MoreApr. 7, 2017

A molecular clue to longevity
Understanding the processes that regulate aging is crucial to potentially increasing longevity and enhancing quality of life. Using the budding yeast, Saccharomyces cerevisiae (S. cerevisiae), Christopher Lord, Ph.D., Ophir Ospovat and Susan Wente, Ph.D., demonstrated that accumulation of tRNA (transfer RNA) in the nucleus increased replicative life span. These results were published this month in… Read MoreApr. 7, 2017

Par3 Promotes Mammary Cell Survival by an Unexpected Mechanism
Epithelial cells form the lining of cavities and the surfaces of organs and blood vessels in animals. A distinctive feature of epithelial cells is their polarization, as indicated by the segregation of cell cortex proteins into functionally distinct regions. In particular, epithelia have apical and basolateral domains separated by… Read MoreMar. 31, 2017

Vanderbilt study finds natural chemical helps brain adapt to stress
A natural signaling molecule that activates cannabinoid receptors in the brain plays a critical role in stress-resilience — the ability to adapt to repeated and acute exposures to traumatic stress, according to researchers at Vanderbilt University Medical Center. The findings in a mouse model could have broad implications for the potential… Read MoreMar. 30, 2017

Discovering the Secrets of a Cancer Drug Resistance Protein
One way that many forms of cancer evade the toxic effects of chemotherapeutic drugs is through expression of the P-glycoprotein. This membrane protein uses energy from the hydrolysis of ATP to transport over 200 structurally distinct compounds, including many drugs, out of the cell. Because of its widespread expression in… Read MoreMar. 21, 2017
