磷脂酰肌醇3激酶在肿瘤细胞信号转导中起着重要的调节作用,许多因子可以使磷脂酰肌醇3-激酶活化,引起蛋白激酶B与细胞膜的结合,在磷酸肌醇依赖激酶的参与下,蛋白激酶B和苏氨酸和丝氨酸残基发生磷酸化而活化,进入胞质和胞核,激活细胞内酶促级联反应,从而产生生物学效应,其与肿瘤细胞恶性增殖、血管新生和糖酵解有密切的关系.
燐脂酰肌醇3激酶在腫瘤細胞信號轉導中起著重要的調節作用,許多因子可以使燐脂酰肌醇3-激酶活化,引起蛋白激酶B與細胞膜的結閤,在燐痠肌醇依賴激酶的參與下,蛋白激酶B和囌氨痠和絲氨痠殘基髮生燐痠化而活化,進入胞質和胞覈,激活細胞內酶促級聯反應,從而產生生物學效應,其與腫瘤細胞噁性增殖、血管新生和糖酵解有密切的關繫.

Phosphatidylinositol 3-kinase (PI3K) plays an important role in the regulation and signal transduction of tumor cells.PI3K is activated by many factors, which leads to protein kinase B (PKB or Akt) binding to cell membrane.With the help of the phosphoinositide-dependent kinase in the PI3K/Akt signal transduction pathway, Akt is phosphorylated with threonine and serine, activated and enters the cytoplasm and nucleus, which mediates enzymatic cascade reaction to produce biological effects.It is closely related with proliferation,angiogenesis and glycolysis of malignant tumor cells.
