[ABSTRACT]Objective To investigate the effect of the gene expression of Yes-associated protein 1 (YAP1) mediated by miR-141-3p on the invasion, migration, and chemosensitivity of advanced non-small cell lung cancer (NSCLC) cells. ?MethodsAdvanced NSCLC and adjacent tissue samples were collected from 50 patients, and quantitative reverse transcription-polymerase chain reaction was used to measure the expression of miR-141-3p and YAP1. NSCLC cell line was selected, and miR-141-3p inhibitor and siRNA-YAP1 were designed. The cells were divided into blank group, miR-141-3p mimic group, miR-141-3p inhibitor group, YAP1 vector group, siRNA-YAP1 group, and miR-141-3p mimic+siRNA-YAP1 group. The cells in the logarithmic growth phase were inoculated on a 96-well plate and cultured with 10 mg/L cisplatin at 37 ℃ and a volume fraction of CO2 of 0.05; the changes in cell migration, invasion, and drug resistance were observed, and the expression of miR-141-3p, YAP1, and proteins related to the TGF-β signaling pathway (TGF-β and Smad2) was measured. ?Results Compared with the adjacent tissue, the advanced NSCLC tissue showed high expression of miR-141-3p and YAP1 (t=23.19,17.32;P<0.05). Overexpression of miR-141-3p or YAP1 reduced the expression of TGF-β and Smad2, promoted the invasion and migration of cancer cells, and reduced cell viability after cisplatin treatment (Tukeys test, P<0.05), while silencing of miR-141-3p or YAP1 increased the expression of TGF-β and Smad2, inhibited the migration and invasion of cancer cells, and increased cell viability after cisplatin treatment (Tukeys test, P<0.05;F=82.670-181.000,P<0.05).?Conclusion Downregulation of miR-141-3p may regulate the invasion, migration, and chemosensitivity of advanced NSCLC cells by inhibiting the expression of the YAP1 gene and activating the TGF-β signaling pathway.

肺癌病死率位居惡性腫瘤的首位,多數(shù)病人確診時(shí)已是晚期失去手術(shù)機(jī)會(huì),其預(yù)后極差,多歸因于目前缺乏有效的早期診斷途徑[1-4]。晚期非小細(xì)胞肺癌(NSCLC)病人多采用以化療為主的治療方案[5-6]。值得注意的是腫瘤治療效果與病人個(gè)體化特征密切相關(guān),即便同一種治療方案應(yīng)用于有著相似臨床診斷、臨床分期及藥物種類和劑量的不同患癌個(gè)體,亦可能產(chǎn)生不同反應(yīng)?;熋舾行砸殉蔀楹饬炕熜Ч闹饕笜?biāo)[4],而耐藥性在治療過程中很常見。微小RNA(microRNA)是一類非編碼RNA,可通過調(diào)節(jié)特定基因的表達(dá),參與腫瘤發(fā)展進(jìn)程[7]。近年來的研究表明,microRNA在肺癌的發(fā)展、診療、放化療敏感性等方面均發(fā)揮著重要作用[8-9]。例如,miR-141已被證實(shí)可作為NSCLC潛在的診斷標(biāo)志物[10-11];miR-141-3p在對(duì)化療有效的NSCLC病人中呈低表達(dá)[12]。但目前關(guān)于miR-141-3p是否參與晚期NSCLC治療過程中化療敏感性機(jī)制的研究未見報(bào)道。本研究以體外實(shí)驗(yàn)方式,采用細(xì)胞轉(zhuǎn)染探究miR-141-3p在NSCLC細(xì)胞系的表達(dá),并探討其對(duì)晚期NSCLC化療敏感性的影響及其作用機(jī)制,為逆轉(zhuǎn)肺癌化療耐藥性提供臨床依據(jù)。

通過對(duì)50例晚期NSCLC組織及24例癌旁組織的qRT-PCR檢測結(jié)果顯示,與癌旁組織比較,癌組織中miR-141-3p和YAP1表達(dá)均顯著升高,差異均有統(tǒng)計(jì)學(xué)意義(t=23.19、17.32,P均<0.05)。見圖1。

2.2 miR-141-3p對(duì)YAP1基因表達(dá)的調(diào)控

為研究miR-141-3p在NSCLC細(xì)胞中的靶向關(guān)系,通過生物學(xué)網(wǎng)站對(duì)其進(jìn)行分析,結(jié)果顯示,miR-141-3p和YAP1存在結(jié)合位點(diǎn)。雙熒光素酶報(bào)告基因預(yù)測結(jié)果顯示,與mimic-NC組相比較,YAP1野生型3UTR的熒光素酶活性能被miR-141-3p抑制(t=7.643,P<0.05),而對(duì)YAP1突變型3UTR的熒光素酶活性沒有影響(P>0.05)。說明miR-141-3p能特異性結(jié)合YAP1的3UTR區(qū)并在轉(zhuǎn)錄后水平下調(diào)FANCM基因表達(dá)。見圖2。

差異有顯著意義(F=116.8,P<0.05)。與Blank組相比,miR-141-3p mimic組YAP1基因表達(dá)上升(Tukeys檢驗(yàn),P<0.05),miR-141-3p inhibitor組YAP1基因表達(dá)下降(Tukeys檢驗(yàn),P<0.05)。說明miR-141-3p表達(dá)能夠調(diào)控YAP1表達(dá)。見圖3。

2.4 miR-141-3p對(duì)晚期NSCLC細(xì)胞的增殖、遷移和耐藥性的影響

結(jié)果顯示,各組NSCLC細(xì)胞的增殖、遷移和耐藥性比較,差異有顯著意義(F=82.670~181.000,P均<0.05)。與Blank組相比,miR-141-3p mimic組和YAP1 vector組癌細(xì)胞侵襲、遷移能力明顯增強(qiáng),順鉑處理后細(xì)胞存活率明顯增加,差異有顯著意義(Tukeys檢驗(yàn),P均<0.05);而miR-141-3p inhibitor組和siRNA-YAP1組癌細(xì)胞侵襲、遷移能力明顯減弱,順鉑處理后細(xì)胞存活率明顯降低,差異有顯著性(Tukeys檢驗(yàn),P均<0.05)。Blank組和miR-141-3p mimic+siRNA-YAP1組各指標(biāo)無顯著差異(P>0.05)。說明miR-141-3p inhibitor+pcDNA-YAP1組逆轉(zhuǎn)了這一趨勢。見圖4、5。

2.5 miR-141-3p對(duì)TGF-β信號(hào)通路相關(guān)蛋白影響

3 討 論

microRNA已被證實(shí)在人類腫瘤的抗放化療機(jī)制中發(fā)揮重要作用。例如,LIU等[13]在其研究中利用microRNA分子譜分析法篩選與LASS2相關(guān)的microRNA,以為鑒別化療耐藥和化療敏感性提供依據(jù),其結(jié)果發(fā)現(xiàn)miR-93抑制劑可增強(qiáng)si-LASS2轉(zhuǎn)染腫瘤細(xì)胞的化學(xué)敏感性。LANG等[14]報(bào)道,采用miR-24靶向沉默S100A8基因可提高子宮內(nèi)膜癌細(xì)胞對(duì)紫杉醇的化療敏感性。劉娜等[15]在其研究中利用慢病毒表達(dá)載體轉(zhuǎn)染卵巢癌細(xì)胞株,構(gòu)建miR-200a表達(dá)上調(diào)模型,并結(jié)合MTT實(shí)驗(yàn)、PCR和免疫印跡檢測發(fā)現(xiàn)miR-200a可能通過調(diào)控耐藥相關(guān)ABC家族基因如ABCB3、ABCC1、ABCC2、ABCC3和ABCG2的表達(dá),增加卵巢癌細(xì)胞對(duì)紫杉醇的敏感性。肖悅等[16]通過構(gòu)建穩(wěn)定表達(dá)miR-18a的白血病細(xì)胞轉(zhuǎn)染模型,發(fā)現(xiàn)miR-18a能夠通過靶定ATM調(diào)節(jié)白血病細(xì)胞HL-60對(duì)VP-16和VCR化療敏感性。鑒于microRNA能在基因編碼水平上反映腫瘤的耐藥性機(jī)制[17-19],那么通過構(gòu)建特定表達(dá)干預(yù)的細(xì)胞轉(zhuǎn)染模型,可有助于探究特定microRNA與腫瘤耐藥性的關(guān)聯(lián)及其作用機(jī)制。

在本研究前期,我們通過生物信息學(xué)方法篩選出晚期NSCLC過表達(dá)基因miR-141-3p,且在線生物學(xué)預(yù)測軟件報(bào)道m(xù)iR-141-3p調(diào)控YAP1,YAP1在晚期NSCLC亦高表達(dá),因此推測miR-141-3p通過調(diào)控YAP1影響晚期NSCLC。本研究首先通過qRT-PCR驗(yàn)證組織中miR-141-3p和YAP1的表達(dá)。結(jié)果顯示,與癌旁組織相比,晚期NSCLC中miR-141-3p和YAP1呈高表達(dá)。進(jìn)而,我們通過細(xì)胞轉(zhuǎn)染分為不同干預(yù)組別,探討了miR-141-3p對(duì)YAP1的調(diào)控關(guān)系,結(jié)果顯示,過表達(dá)miR-141-3p能夠促進(jìn)YAP1基因和蛋白的表達(dá),沉默miR-141-3p能夠抑制YAP1基因和蛋白的表達(dá),說明miR-141-3p的表達(dá)能夠調(diào)控YAP1的表達(dá)。進(jìn)一步研究結(jié)果表明,通過轉(zhuǎn)染miR-141-3p mimic或YAP1vector,相比Blank組,過表達(dá)miR-141-3p或YAP1能夠抑制TGF-β和Smad2表達(dá),促進(jìn)癌細(xì)胞侵襲遷移,增加細(xì)胞對(duì)順鉑耐藥性。而通過miR-141-3pinhibitor或si-YAP1轉(zhuǎn)染處理,則顯示沉默miR-141-3p或YAP1能夠提高TGF-β和Smad2表達(dá),抑制癌細(xì)胞轉(zhuǎn)移侵襲,降低細(xì)胞對(duì)順鉑耐藥性。與此同時(shí),Blank組和miR-141-3p mimic+siRNA-YAP1組各項(xiàng)指標(biāo)無顯著差異,提示后者逆轉(zhuǎn)了這種趨勢。這說明miR-141-3p能夠通過YAP1促進(jìn)晚期NSCLC細(xì)胞的增殖、遷移和耐藥。

基于以上實(shí)驗(yàn)探究,我們推測,miR-141-3p下調(diào)可能通過抑制YAP1基因表達(dá),激活TGF-β信號(hào)通路,進(jìn)而調(diào)控晚期NSCLC細(xì)胞侵襲轉(zhuǎn)移和化療敏感性。值得注意的是,TGF-β家族是一類功能復(fù)雜的細(xì)胞因子,可廣泛參與各種病理生理過程,介導(dǎo)腫瘤細(xì)胞的分化與增殖[20-22]。TGF-β信號(hào)通路相關(guān)蛋白如Smad2,亦參與人類腫瘤進(jìn)程,與乳癌、肺癌等發(fā)生發(fā)展相關(guān)[23-24]。TGF-β信號(hào)通路及其相關(guān)蛋白組成腫瘤抑制通路,介導(dǎo)腫瘤細(xì)胞生長,并且可激活一系列信號(hào)通路如MAPK、ERK等信號(hào)通路[25-26]。本研究中,miR-141-3p下調(diào)及YAP1基因表達(dá)抑制促進(jìn)了TGF-β和Smad2表達(dá)的提升,進(jìn)而激活TGF-β信號(hào)通路,對(duì)于降低順鉑耐藥性具有重要作用。既往研究已報(bào)道TGF-β信號(hào)通路與化療耐藥有關(guān),并可通過調(diào)控TGF-β信號(hào)通路抑制腫瘤耐藥[27]。孫彩霞等[28]報(bào)道,轉(zhuǎn)染miR-141模擬物可降低卵巢癌細(xì)胞株SKOV-3和ES-2細(xì)胞對(duì)卡鉑的敏感性,提示檢測miR-141表達(dá)水平在預(yù)測卵巢癌對(duì)卡鉑敏感性、評(píng)估病人預(yù)后及其合理指導(dǎo)綜合治療等方面的臨床意義。

綜上所述,本文結(jié)果顯示,miR-141-3p下調(diào)可能通過抑制YAP1基因表達(dá),激活TGF-β信號(hào)通路,進(jìn)而調(diào)控晚期NSCLC細(xì)胞侵襲轉(zhuǎn)移和化療敏感性。本研究可為人類探討NSCLC耐藥機(jī)制提供新途徑,microRNA與NSCLC耐藥間的相關(guān)性將為逆轉(zhuǎn)其耐藥性提供一種全新的思路和策略。然而,本研究僅在細(xì)胞實(shí)驗(yàn)中初步探究miR-141-3p對(duì)NSCLC影響的作用機(jī)制,是否存在其他潛在靶點(diǎn)及其作用機(jī)制均未可知,其將為今后研究的主要方向,進(jìn)而為NSCLC的診治提供分子生物學(xué)依據(jù)。
