过氧化物酶体增殖物激活受体(过氧化物酶体增殖物激活受体)同种型的特征和生物学作用是众所周知的单胃动物,但不是在反刍动物。然而,丰富的信息已经积累了略多于十年的反刍动物的PPARs,包括同种型组织分布,响应合成和天然激动剂,基因靶点,影响其表达的因素。功能表征表明,在单胃,过氧化物酶体增殖物激活物受体同种型控制基因的表达参与脂质代谢,抗炎反应,发展和增长。然而,与小鼠相反,PPARγ基因网络似乎控制泌乳反刍动物的乳脂合成。与单胃动物一样,反刍动物中的PPAR同种型被长链脂肪酸激活,因此,使其成为通过营养物微调该物种代谢的理想候选者。在这方面,利用反刍动物和单胃动物积累的信息,我们提出了一个涵盖奶牛围产期关键组织的PPAR同种型驱动的生物学功能模型。
Characterization and biological roles of the peroxisome proliferator-activated receptor (PPAR) isotypes are well known in monogastrics, but not in ruminants. However, a wealth of information has accumulated in little more than a decade on ruminant PPARs including isotype tissue distribution, response to synthetic and natural agonists, gene targets, and factors affecting their expression. Functional characterization demonstrated that, as in monogastrics, the PPAR isotypes control expression of genes involved in lipid metabolism, anti-inflammatory response, development, and growth. Contrary to mouse, however, the PPARγ gene network appears to controls milk fat synthesis in lactating ruminants. As in monogastrics, PPAR isotypes in ruminants are activated by long-chain fatty acids, therefore, making them ideal candidates for fine-tuning metabolism in this species via nutrients. In this regard, using information accumulated in ruminants and monogastrics, we propose a model of PPAR isotype-driven biological functions encompassing key tissues during the peripartal period in dairy cattle.
