Question

谁能帮我翻译一下一段英文（医学类） 不要直接搬用在线翻译。。。要语句流畅。。。 大写字母不用翻译

PP2A downregulates Akt activity directly, by
dephosphorylating it at T308 and accumulating evidence
indicates that PP2A acts as a tumor suppressor。
PP2A is an essential phosphatase critically involved
in regulation of cell cycle progression and DNA
damage responseas well as p53 stability and other
important biochemical events.

Answer 1

pp2A 能通过在T308位点的去磷酸化的作用，直接下调AKT的活性，之前的证据表明PP2A能抑制肿瘤。PP2A作为一种关键的磷酸化酶，参与了细胞周期的调控、DNA损伤反应、p53的稳定性以及其他重要的生化活动。
