The review concludes with a summary supporting a role for lifestyle factors that favorably impact inflammatory process involved in obesity and PCOS to improve ovarian function.”
“Biotransformation

of steroids with 4-ene-3-one functionality such as progesterone Navitoclax concentration (I), testosterone (II), 17 alpha-methyltestosterone (III), 4-androstene-3,17-dione (IV) and 19-nortestosterone (V) were studied by using a fungal system belonging to the genera of Mucor (M881). The fungal system efficiently and quantitatively converted these steroids in regio- and stereo-selective manner into corresponding 6 beta,11 alpha-dihydroxy compounds. Time course experiments suggested that the transformation was initiated by hydroxylation

at 6 beta- or 11 alpha-(10 beta-hydroxy in case of V) to form monohydroxy derivatives which upon prolonged incubation were converted into corresponding 613,11oc-dihydroxy derivatives. The fermentation studies carried out using 5 L table-top fermentor with substrates (I and II) clearly indicates that 6 beta,11 alpha-dihydroxy derivatives of steroids with 4-ene-3-one functionality check details can be produced in large scale by using M881.

“Chromatin immunoprecipitation followed by sequencing (ChIP-seq) is a burgeoning technique which combines Chromatin immunoprecipitation (ChIP) with massively parallel DNA sequencing to detect protein-DNA binding events, Raf inhibitor histone modifications, nucleosomes positioning and DNA methylation on a genome-wide scale. Motivated by the tremendous progress in next-generation sequencing (NGS) technology, ChIP-seq offers higher resolution, less noise, and broader coverage than conventional microarray based ChIP-chip. With the decreasing cost of sequencing, ChIP-seq has become an indispensable tool for studying gene regulation and epigenetic mechanisms. In this review, we describe its latest advances, with an emphasis on issues related to data analysis and its application.”
“Cells sense the rigidity of their environment

and respond to it. Most studies have been focused on the role of adhesion complexes in rigidity sensing. In particular, it has been clearly shown that proteins of the adhesion complexes were stretch-sensitive and could thus trigger mechano-chemical signaling in response to applied forces. In order to understand how this local mechano-sensitivity could be coordinated at the cell scale, we have recently carried out single cell traction force measurements on springs of varying stiffness. We found that contractility at the cell scale (force, speed of contraction, mechanical power) was indeed adapted to external stiffness and reflected ATPase activity of non-muscle myosin II and acto-myosin response to load.
