Introduction

食管鱗狀細(xì)胞癌（Esophagealsquamouscellcarcinoma，ESCC）是一種常見的惡性腫瘤，其患病率和死亡率均居高不下?，F(xiàn)有的臨床診療手段尚不能完全控制其發(fā)展，因此有必要進(jìn)一步研究其發(fā)生發(fā)展的分子機(jī)制，為診斷和治療提供更多的思路。

Methods

本研究收集了30例ESCC患者的臨床樣本，并采用實(shí)時熒光定量PCR、蛋白質(zhì)印跡、免疫熒光染色等方法檢測Gli1和YAP1的表達(dá)水平以及其與臨床病理參數(shù)之間的關(guān)系；同時，采用細(xì)胞增殖、遷移和侵襲等實(shí)驗(yàn)?zāi)Ｐ停瑱z測Gli1上調(diào)YAP1表達(dá)對ESCC細(xì)胞增殖和侵襲的影響，并探究其作用機(jī)制。

Results

研究發(fā)現(xiàn)，Gli1的上調(diào)與ESCC的分級、分化程度和患者預(yù)后密切相關(guān)，并且可促使YAP1的表達(dá)增加；同時，Gli1上調(diào)YAP1表達(dá)可促進(jìn)ESCC細(xì)胞的增殖、遷移和侵襲，并且這種促進(jìn)作用可能與細(xì)胞周期、細(xì)胞凋亡和EMT等相關(guān)信號通路的調(diào)控有關(guān)。

Conclusions

本研究揭示了Gli1上調(diào)YAP1表達(dá)在食管鱗狀細(xì)胞癌發(fā)生發(fā)展中的重要作用，為今后的臨床診斷和治療提供了新的思路Introduction
