I. Background | |
癌癥相關(guān)炎癥的特征是存在特定的炎癥細胞和炎癥介質(zhì),包括細胞因子和趨化因子。 最近的證據(jù)表明,信號轉(zhuǎn)導(dǎo)和轉(zhuǎn)錄激活因子(STAT)家族蛋白,特別是 STAT3,在惡性轉(zhuǎn) 化開始和癌癥進展過程中,在選擇性誘導(dǎo)和維持癌前炎癥微環(huán)境中起著至關(guān)重要的作用。 信號轉(zhuǎn)導(dǎo)和轉(zhuǎn)錄激活因子 3(STAT3)是一種轉(zhuǎn)錄激活因子,它將細胞外受體的信號 直接傳遞到細胞核,介導(dǎo)一些基因的表達,在細胞凋亡等細胞過程中發(fā)揮重要作用。在細 胞因子和生長因子的作用下,STAT3 被受體相關(guān) Janus 激酶(JAK)磷酸化,形成同二聚 體或異二聚體,并轉(zhuǎn)位到細胞核中,作為轉(zhuǎn)錄激活劑發(fā)揮作用。STAT3 信號傳導(dǎo)是惡性腫 瘤的主要內(nèi)在途徑,因為它在惡性細胞中頻繁激活,并且在調(diào)節(jié)腫瘤微環(huán)境中對癌癥發(fā)炎 至關(guān)重要的許多基因中起關(guān)鍵作用。 |
