PIK3CA

PIK3CA，即磷脂酰肌醇4,5-二磷酸3-激酶催化亞基α，別名PI3K-alpha。PIK3CA由人類PIK3CA基因編碼，該基因位于3號染色體的q26.3區域，包含21個外顯子，編碼1068種氨基酸，產生一組長124kD的蛋白。PIK3CA的作用機制涉及催化膜脂磷脂酰肌醇-4,5-二磷酸[PI(4,5)P2]到第二信使PI(3,4,5)P3（也被稱為PIP3）的轉化，激活AKT-mTOR信號通路，促進細胞存活、增殖、生長和運動。PIK3CA是癌癥中最常見的突變基因之一，其激活突變在乳腺癌、子宮內膜癌、膀胱癌、結腸直腸癌等多種癌癥中均有發現，參與腫瘤發生、進展及轉移定植。PIK3CA基因的突變導致PI3K/AKT通路水平上調，進而參與腫瘤發生。

Immunofluorescence staining of Hela Cells with CSB-RA578819A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeated by 0.2% TritonX-100, and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4℃. Nuclear DNA was labeled in blue with DAPI. The secondary antibody was FITC-conjugated AffiniPure Goat Anti-Rabbit IgG (H+L).
