冷应激条件下猪脂肪组织中脂联素及其受体mRNA水平的表达变化
Adiponectin and its Receptors mRNA Levels in Swine Adipose Tissue in the Condition of Cold Stress
摘要
Abstract
The adipose tissue samples in the neck, pars dorsalis and viscera mesenteria of pig under the temperature of -15~ - 10 °C , -10~ -5 °C , - 5~0 °C , 15 -18 °C were collected for sthdying the expression of adiponectin and adiponectin receptors mRNA by Real-time fluorescent quantification reverse transcriptase PCR to explore the effects of cold stress on lipome-tabolism. The results showed that the expression of adiponectin mRNA in the neck, pars dorsalis and viscera mesenteria gradually decreased with the increasing cold stimulus and the differences were significant (P<0. 05). The levels of AdipoR 1 and AdipoR 2 mRNA in viscera mesenteria firstly increased and then declined (P<C0. 01). The expression of AdipoR 2 mRNA in pars dorsalis gradually decreased and then returned the normal level; AdipoR 1 mRNA of the different groups had no obvious difference. AdipoR 2 mRNA in the neck went up gradually and declined to the normal level(P<0. 01) ; AdipoR 1 mRNA firstly increased then down-regulated to normal level and went up again(P<0. 01). It was concluded that adiponectin and AdipoR are associated with the process of cold stress, which may play important role on redistribution of adipose tissue under animal cold stress.关键词
