Proteomic analysis of Tianzhu White Yak (Bos grunniens) testis at different sexual developmental stages.

To explore the protein expression profiles of white yak (Bos grunniens) testis at different sexual developmental stages. The protein profiles of yak testis were determined using two-dimensional electrophoresis and the expression levels of 298 protein spots were analyzed. Mass spectrometry was performed to identify those significantly differential expressed proteins; Western blotting was used to confirm the results.

MITF and PU.1 inhibit adipogenesis of ovine primary preadipocytes by restraining C/EBPβ.

Background: PU box-binding protein (PU.1) is a master gene of hematopoietic lineage and an important specific transcription factor in osteoclast lineage. There is proof of its expression in adipose tissue, and it is known to significantly and negatively affect adipogenesis.
