質(zhì)子感知卵巢癌G蛋白偶聯(lián)受體1（OGR1）屬于G蛋白偶聯(lián)受體超家族OGR1亞家族4個成員（TDAG8,OGR1,G2A和GPR4）之一,在腫瘤及炎性等病理酸性條件下被激活而調(diào)節(jié)細胞的生理病理過程。病理酸性微環(huán)境的形成與細胞的糖酵解途徑增強有關,而這個過程是由低氧誘導因子（HIF）的過度激活及其誘導多種靶基因的表達來決定的。我們對腫瘤大數(shù)據(jù)進行分析研究后發(fā)現(xiàn),HIF誘導的基因中也包含OGR1,所以我們推測OGR1可能與腫瘤細胞適應低氧或酸性環(huán)境的生存能力有關。在該研究中我們將探索OGR1與腫瘤在酸性環(huán)境中存活、轉移和凋亡等復雜生物學特性之間的關系,闡明OGR1的生理功能和病理機制,為腫瘤細胞抵抗酸性的本質(zhì)方面以及在腫瘤治療戰(zhàn)略方面提出新的觀點。在研究中,首先克隆了人類OGR1基因并構建OGR1原核表達載體。繼而又構建OGR1真核表達質(zhì)粒pHBLV-CMV-EF1中。通過酶消化和測序鑒定確認正確后。用lipofectamine2000將質(zhì)粒轉染到A549肺癌細胞株中。用實時熒光定量PCR基因檢測技術來檢測A549細胞中外源ORG1基因的表達。用Western Blot法檢測蛋白表達;在研究...
