MAPK 是 mitogen-activated protein kinase 的缩写,指“丝裂原活化蛋白激酶”:一类在细胞内信号传导中非常关键的蛋白激酶,常通过级联反应调控细胞增殖、分化、应激反应与凋亡等过程。(该缩写在不同语境下也可能泛指 MAPK 信号通路。)
/ˌɛm eɪ piː ˈkeɪ/
MAPK plays a key role in transmitting signals from the cell surface to the nucleus.
MAPK 在将信号从细胞表面传递到细胞核的过程中起关键作用。
In many cancers, abnormal activation of the MAPK pathway drives uncontrolled cell growth, so targeted inhibitors are often studied as potential treatments.
在许多癌症中,MAPK 通路的异常激活会推动细胞失控增殖,因此人们常研究靶向抑制剂作为潜在治疗手段。
MAPK 来自首字母缩略:Mitogen-Activated Protein Kinase。该术语在分子生物学与细胞信号传导研究中广泛使用,强调其“被丝裂原/生长信号激活”以及“激酶(kinase)催化磷酸化”的核心功能。
