目的研究急性肺损伤(acute lung in jury,ALI)大鼠小肠Gq/11蛋白的表达变化。方法40只健康雄性W istar大鼠尾静脉注射油酸(ole ic ac id,OA)复制ALI模型,并将其分为对照组(C组)和油酸组(OA组),再根据观测时限再将OA组分为30、60、90、120 m in 4个组。紫外法测定血管紧张肽转化酶(ACE)活性,免疫印迹法检测各组大鼠小肠黏膜的Gq/11蛋白含量。结果OA各组随时间延长Gq/11蛋白含量较C组分别增加至(138.91±23.03)%、(143.99±23.01)%、(150.68±26.25)%、(173.05±21.51)%(P<0.05或0.01)。OA组血浆和小肠LDH活性及MDA含量增高(P<0.05或0.01),血浆ACE活性较对照组降低(P<0.01),而小肠ACE活性则随时间延长逐渐增高(P<0.01)。结论Gq/11蛋白表达上调在ALI并发小肠损伤中有一定作用。

Aquaporins are small integral membrane proteins that selectively transport water and some small solutes in mammals, plants and lower organisms. Continued studies of the aquaporins are providing detailed tissue localization and the important physiological roles of aquaporins in urinary, respiratory, digestive and nervous systems. Based on the importance of aquaporin studies in the field of structural chemistry in biomembranes, American scientist Peter Agre won the 2003 Chemistry Nobel Prize for the discovery of water channels.
