Fig. 6From: Decreased testosterone levels after caponization leads to abdominal fat deposition in chickensThe inhibition of lipid depositon by testosterone in vitro. a Testosterone inhibits lipid deposition in primary chicken preadipocytes. Primary preadipocytes were obtained from AF tissues of male chickens, and were cultured with 0 or 30Ā ng/mL testosterone for 4 d, after which cells were collected, and cell differentiation was determined by oil-red-O staining. b RXRG and FABP7 mRNA expression were significantly down-regulated in cells treated with 30Ā ng/mL testosterone compared with untreated cells. However, FABP3 mRNA expression was significantly up-regulated. Data are means Ā± SEM, nā=ā3. *Pā<ā0.05; **Pā<ā0.01Back to article page
