单羧酸转运蛋白：在挥发性脂肪酸转运中的作用及影响基因表达的因素

摘要

Diet generates plenty of volatile fatty acids by microbial digestion in intestinal tract to provide energy for animals. Monocarboxylate transporters ( MCTs) play an important role in absorption and transport of vola-tile fatty acids in intestinal tract. The study on MCTs has great significance to find the mechanism. This paper reviewed the transport mechanisms of volatile fatty acids, MCT gene expressions and tissue distribution, and factors infuluncing MCT gene expressions and the mechanism.%饲粮在动物消化道内经微生物发酵产生大量的挥发性脂肪酸为动物体供能，单羧酸转运蛋白( MCT)在动物肠道对挥发性脂肪酸的吸收转运中起到重要作用，对MCT进行深入的研究对探明动物挥发性脂肪酸吸收转运的机理有重要意义。本文就挥发性脂肪酸的转运机制、MCT基因表达与组织分布、影响MCT基因表达的因素及作用机制进行综述。
