丙泊酚通過上調(diào)miR-219-5p抑制肝癌生長和轉(zhuǎn)移的作用與機制研究
發(fā)布時間:2021-01-05 02:28
研究背景原發(fā)性癌是常見的惡性腫瘤,手術(shù)切除是目前治療肝癌最常用和最有效的方法,然而即使是根治性手術(shù)切除的患者,5年的復(fù)發(fā)率仍高達70%。圍術(shù)期是癌細胞轉(zhuǎn)移的關(guān)鍵時間窗,丙泊酚作為腫瘤切除手術(shù)常用的靜脈麻醉藥,研究顯示其具有抑制腫瘤生長和轉(zhuǎn)移的作用。丙泊酚抑制肝癌的具體作用及機制目前國內(nèi)外尚無明確報道。mniRNAs在腫瘤發(fā)生發(fā)展過程中發(fā)揮著重要作用,通過前期實驗發(fā)現(xiàn),丙泊酚可顯著上調(diào)miR-219-5p表達,miR-219-5p在多種腫瘤中均具有抑癌作用。因此我們探究丙泊酚是否通過上調(diào)miR-219-5p的表達抑制肝癌的生長與轉(zhuǎn)移,并就具體作用機制作進一步探討。研究目標(biāo)1.驗證丙泊酚通過上調(diào)miR-219-5p的表達抑制肝癌細胞增殖與侵襲轉(zhuǎn)移。2.探討丙泊酚上調(diào)miR-219-5p抑制肝癌侵襲轉(zhuǎn)移與EMT進程的作用機制,初步探討miR-219-5p的作用靶基因RAB18。3.揭示RAB18在人肝癌細胞系、肝癌組織及其匹配癌旁肝組織中的表達水平,及其在肝癌患者預(yù)后評估的價值;探討肝癌發(fā)生發(fā)展過程中RAB18的功能及調(diào)控機制,以尋求肝癌侵襲轉(zhuǎn)移新的理論依據(jù)。研究內(nèi)容與方法1.揭示丙泊酚通過...
