xanthine
解釋
n. 名詞 【化學】黃嘌呤；黃質，羥基嘌呤。-
Protein kinase a is camp - dependent kinase, one of the most important signal transduction pathways, plays a pivotal role in growth, differentiation, tumor occur, cell cycle control, etc. pka activators such as camp, 8 - br - camp or phosphodiesterase ( pde ) inhibitor isomethyl butyl xanthine ( imbx ) or purified pka catalytic subunit all can inhibit germinal vesicle breakdown ( gvbd ) and meiotic maturation in mouse oocytes, also in xenopus oocytes
蛋白激酶a （ proteinkinasea ， pka ）是依賴于camp的絲蘇氨酸蛋白激酶，是重要的信號傳導途徑之一，廣泛參與許多生命過程，包括生長、分化、腫瘤發生、細胞凋亡、細胞周期調控等。以小鼠卵母細胞為實驗對象，給予pka激動劑camp 、 8 - br - camp或磷酸二酯酶抑制劑imbx （ isomethylbutylxanthine ）均可抑制小鼠卵母細胞的胚泡破裂及減數分裂成熟。 -
