NQO1/PKLR通過糖代謝重編程調控乳腺癌演進的機制研究
發(fā)布時間:2021-04-17 21:11
研究背景:乳腺癌是全球常見的惡性腫瘤之一,也是導致女性死亡的重要原因之一。作為一種異質性疾病,其以不同的激素受體表達狀態(tài)為特征,而這些特征也常用于預測乳腺癌不同亞型的靶向治療。目前,臨床上已有多種治療乳腺癌的靶向藥物,如雌激素受體(ER)靶向藥物--他莫昔芬、HER2靶向藥物--曲妥珠單抗。以上靶向藥物雖然可有效抑制乳腺癌的演進,但侵襲和轉移仍是導致乳腺癌患者死亡的主要病因。因此,深入探究乳腺癌侵襲轉移的相關調控基因及分子通路作用機制,將有利于明確乳腺癌的早期診斷及治療靶點,對改善乳腺癌的個體化治療及改善患者的預后具有重要臨床價值。醌氧化還原酶(NAD(P)H:quinone oxidoreductase-1,NQO1),也被稱為DT-硫辛酰胺脫氫酶,定位于染色體16p22。它通過受體NAD(P)H催化醌類及其衍生物,使其失去雙電子發(fā)生還原反應,避免了對細胞的損傷。值得注意的是,當NQO1cDNA609位點發(fā)生突變時可導致細胞解毒致癌物的能力降低,增加致癌物的作用,導致某種易感個體發(fā)生惡性病變,從而增加個體罹患多種惡性腫瘤的危險。近年來,NQO1在多種惡性腫瘤中所扮演的角色備受學者的關...
