简介:瞄准:为了在steroidogenesis和机制上调查Cox7a2的规章的功能,在TM3老鼠Leydig房间包含了。方法:Cox7a2的cDNA从TM3老鼠Leydig房间被克隆。它是短暂基因transfection在表达式上为Cox7a2克隆到回来的pDsRed-Express-N1和transfected进TM3鼠标Leydig房间的潜水艇。Steroidogenesis影响了由在表示Cox7a2上被ELISA学习。得到这效果的机制,steroidogenic的表示尖锐规章(星)蛋白质和反应的氧种类(ROS)被西方的污点和氟量计分别地检验。结果:Cox7a2(249bp)的cDNA从Leydig房间被克隆并且由定序的DNA证实了。在构造pDsRed-Express-N1-Cox7a2是回来的transfected进TM3老鼠Leydig房间以后,Cox7a2禁止了导致的luteinizing(LH)不仅睾丸激素的分泌物而且星蛋白质的表示。同时,Cox7a2在TM3老鼠Leydig房间增加了ROS的活动。结论:Cox7a2禁止了导致LH的星蛋白质表示,和作为结果的睾丸激素生产,至少部分地,由在TM3鼠标Leydig房间增加ROS活动。
