Abstract : Domestic yaks (Bos grunniens) provide meat and other necessities for Tibetans living at high altitude on the Qinghai-Tibetan Plateau and in adjacent regions. Comparison between yak and the closely related low-altitude cattle (Bos taurus) is informative in studying animal adaptation to high altitude. Here, we present the draft genome sequence of a female domestic yak generated using Illumina-based technology at 65-fold coverage. Genomic comparisons between yak and cattle identify an expansion in yak of gene families related to sensory perception and energy metabolism, as well as an enrichment of protein domains involved in sensing the extracellular environment and hypoxic stress. Positively selected and rapidly evolving genes in the yak lineage are also found to be significantly enriched in functional categories and pathways related to hypoxia and nutrition metabolism. These findings may have important implications for understanding adaptation to high altitude in other animal species and for hypoxia-related diseases in humans.

Title : Regulation of hormone-sensitive lipase expression by saturated fatty acids and hormones in bovine mammary epithelial cells - Yonezawa_2008_Biochem.Biophys.Res.Commun_376_36

Abstract : Hormone-sensitive lipase was firstly identified as an epinephrine-induced lipase in adipocyte. HSL mRNA was detected by RT-PCR in cloned bovine mammary epithelial cells (bMEC) and bovine lactating mammary gland. Saturated fatty acids (stearate and palmitate), but not unsaturated fatty acids (oleate and linoleate) induced up-regulation of HSL mRNA in a time- and concentration-dependent manner in bMEC. Treatment with insulin (5-10 ng/ml), dexamethasone (50-250 nM) or GH (50 ng/ml) induced down-regulation of HSL. These results suggest that HSL was regulated by fatty acids and some hormones in mammary epithelial cells and thereby play an important role of lipid and energy metabolism.
