| I. Background | |
| 癌癥相關(guān)炎癥的特征是存在特定的炎癥細(xì)胞和炎癥介質(zhì)，包括細(xì)胞因子和趨化因子。 最近的證據(jù)表明，信號(hào)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(kāi)始和癌癥進(jìn)展過(guò)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(hào)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(xì)胞外受體的信號(hào)直 接傳遞到細(xì)胞核，介導(dǎo)一些基因的表達(dá)，在細(xì)胞凋亡等細(xì)胞過(guò)程中發(fā)揮重要作用。在細(xì)胞 因子和生長(zhǎng)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(xì)胞核中，作為轉(zhuǎn)錄激活劑發(fā)揮作用。STAT3 信號(hào)傳導(dǎo)是惡性腫瘤的主 要內(nèi)在途徑，因?yàn)樗趷盒约?xì)胞中頻繁激活，并且在調(diào)節(jié)腫瘤微環(huán)境中對(duì)癌癥發(fā)炎至關(guān)重 要的許多基因中起關(guān)鍵作用。 |
