Epithelial-mesenchymal transition (EMT) is one of the key biological phenomena behind cancer and metastasis. Clinical studies suggest that patients undergoing metformin therapy are less predisposed to cancer but the underlying mechanism is far from clear. Given that metformin also acts as TGF-β inhibitor, we sought to explore whether and how metformin could modulate EMT in a cancer like microenvironment...
In mammals, X-inactivation process is achieved by the cis-spreading of long noncoding Xist RNA over one of the female X chromosomes. The Xist binding accumulates histones H3 methylation and H4 hypoacetylation required for X inactivation that leads to proper dosage compensation of the X-linked genes. Co-transcription of Tsix, an antisense copy of Xist, blocks the Xist coating on the Xi. In mice ES...
Development of an effective vaccine against malaria remains a priority. However, a significant number of individuals living in tropical areas are also likely to be co-infected with helminths, which are known to adversely affect immune responses to a number of different existing vaccines. Here we compare the response to two prototype malaria vaccines: a transmission blocking DNA vaccine based on Pfs25,...
