乳腺癌差異基因篩選及PAIP1對其生物學行為的影響
發(fā)布時間:2025-01-17 16:58
研究背景:乳腺癌是源于乳腺導管上皮的惡性腫瘤,近年來其發(fā)病率呈上升的趨勢,已成為發(fā)病率最高的婦科腫瘤,F(xiàn)已公認,轉移和復發(fā)是導致乳腺癌患者死亡的主要原因,因此,明確乳腺癌的轉移機制、發(fā)現(xiàn)有效的治療靶點是治療乳腺癌的關鍵。研究目的:應用基因芯片技術和高內涵篩選(High Contents Screening, HCS)等較為先進的分子生物學技術明確乳腺癌的差異表達基因,繼而通過體外功能實驗初步探討這些差異基因在乳腺癌演進過程中的作用及可能的分子機制,通過體內實驗驗證差異基因蛋白表達,檢測在乳腺癌預后評估及治療模式風險預測中的臨床應用價值,為乳腺癌提供有效的預后評估新分子標志物及治療靶點。材料與方法:1)應用基因芯片技術檢測20對乳腺癌與正常乳腺組織中的基因表達譜,初步篩選差異表達基因,繼而應用實時熒光定量PCR (Quantitative Real-time PCR, qRT-PCR)和HCS等生物學技術明確乳腺癌的差異表達基因;2)制備慢病毒PAIP1 shRNA質粒,沉默MDA-MB-231乳腺癌細胞中的目的基因,繼而應用熒光標記顯微鏡觀察計數(shù)以及流式細胞技術等檢測細胞增殖、凋亡以及細...
