biosights: July 8, 2013 - Vinculin delivers a clutch performance

submitted by: JCB
At the leading edge of migrating cells, actin assembly and membrane protrusion are closely coupled with the formation of integrin-based focal adhesions that attach to the extracellular matrix. Thievessen et al. reveal that the focal adhesion protein vinculin acts as part of a molecular clutch that engages actin flow to coordinate actin and focal adhesion dynamics. This biosights episode presents the paper by Thievessen et al. from the July 8, 2013, issue of The Journal of Cell Biology and...

Diet, microbiota, and microbial metabolites in colon cancer risk in rural Africans and African Americans

submitted by: sjokeefe
Background: Epidemiologic studies have suggested that most cases of sporadic colon cancer can be attributed to diet. The recognition that colonic microbiota have a major influence on colonic health suggests that they might mediate colonic carcinogenesis. Objective: To examine the hypothesis that the influence of diet on colon cancer risk is mediated by the microbiota through their metabolites, we measured differences in colonic microbes and their metabolites in African Americans with a...
