Abstract (original English)

Abstract BackgroundTwo types of adipose tissue, white adipose and brown adipose, have been identified in mammals. For goat, adipose tissue also plays an important role in improving meat and milk quality. C-type natriuretic peptide (CNP) is a member of natriuretic peptide family. Once CNP binds to natriuretic peptide receptor B (NPR-B), NPR-B induces the production of cGMP, thereby activating PKG and downstream targets. The expression of CNP and NPR-B in adipose tissue led to a hypothesis that CNP could have roles involving in regulation of adipogenesis in goat. However, there are few studies on the relationship between CNP and adipogenesis in goat. In the present study, goat adipose derived stem cells (ADSCs) were isolated and employed to investigate the effect of CNP on adipogenesis in goat.ResultsDuring adipogenic differentiation in goat ADSCs, the expression of NPR-B increased at 4 d and 8 d and reduced at 12 d after differentiation. When goat ADSCs were treated with 100 nM and 1000 nM CNP during adipogenic differentiation, there are more accumulation of lipid droplets in the cytoplasm and the up-regulation in the expression of adipogenesis relative genes including PPAR-γ, FASN and LPL. Interestingly, the expression level of brown adipose genes UCP-1 and PGC-1α were also up-regulated. Furthermore, the cGMP level was increased after treatment with CNP. Adding cGMP analogues 8
