Calcification in atherosclerosis: bone biology and chronic inflammation at the arterial crossroads.

abstract：:The molecular mechanisms by which transcription is selectively activated and precisely controlled by signal transducer and activator of transcription (Stat) factors represent a central issue in cytokine-mediated cellular responses. Stat6 mediates responses to IL-4 and antagonizes Stat1 activated by IFN-gamma. We have ...
