第一部分PLCε shRNA通過(guò)PKCα/β/TBX3/E-cadherin信號(hào)通路抑制膀胱癌細(xì)胞的侵襲和遷移目的:體外實(shí)驗(yàn)研究PLC調(diào)節(jié)膀胱癌細(xì)胞侵襲和遷移的分子機(jī)制。方法:各處理因素作用于膀胱癌細(xì)胞株T24、BIU-87細(xì)胞后,采用劃痕,transwell遷移、侵襲實(shí)驗(yàn)檢測(cè)細(xì)胞的遷移、侵襲能力;QRT-PCR檢測(cè)TBX3,E-cadherin的mRNA表達(dá)水平;Western blot檢測(cè)PLC,PKC,PKCβ,p-PKC,p-PKCβ, TBX3和E-cadherin的蛋白表達(dá)水平;IHC檢測(cè)膀胱癌組織中PLC,PKC,PKCβ的蛋白表達(dá)水平。結(jié)果:劃痕,transwell遷移、侵襲實(shí)驗(yàn)顯示:Ad-shPLC能夠抑制膀胱癌細(xì)胞的遷移、侵襲能力。Western blot結(jié)果顯示Ad-shPLC使PKC、PKCβ在細(xì)胞膜的分布減少,降低PKC、PKCβ的磷酸化水平。Western blot和IHC結(jié)果顯示:PLC高表達(dá)膀胱癌組織與PLC低表達(dá)的膀胱癌組織相比較,PKC、PKCβ的磷酸化水平及在細(xì)胞膜的表達(dá)升高。Western blot和QRT-PCR結(jié)果顯示:Ad-shPLC能夠抑...

重慶醫(yī)科大學(xué)碩士研究生學(xué)位論文35圖1.3. 下調(diào)PLCε的表達(dá)抑制TBX3的表達(dá)和增加E-cadherin的表達(dá)。a)細(xì)胞感染Ad-HK和 Ad-shPLCε 48h后,提取總蛋白,western blot檢測(cè)TBX3, E-cadherin 蛋白表達(dá);b)同樣條件下,提取細(xì)胞總RNA,QRT-PCR檢測(cè)TBX3, E-cadherin的mRNA表達(dá)水平并與β-actin做比對(duì)做柱狀圖。*P< 0.05, **P<0.01.Fig1.3. Down-regulation of PLCε repressed TBX3 expression and increased E-cadherinexpression. a) Cells were treated with Ad-HK and Ad-shPLCε, follow by incubated for 48h, theprotein expressions of TBX3 and E-cadherin were measured by using western blot; b) Underthe same condition, total RNA was extracted and qRT-PCR was performed onreverse-transcribed RNA using primers specific toTBX3, E-cadherin and mRNA levels werenormalized to β-actin. *P < 0.05, **P<0.01.2.4 PLCε通過(guò)TBX3介導(dǎo)E-cadherin的表達(dá)如圖1.4所示,細(xì)胞轉(zhuǎn)染pGenesil-shTBX3后,能夠在mRNA及蛋白水平下調(diào)TBX3的表達(dá)及抑制細(xì)胞的遷移、侵襲能力,并且當(dāng)pGenesil-shTBX3與Ad-shPLC 共同處理細(xì)胞后,與Ad-shPLC 處理組比較
