目的觀察外源性雌激素受體β1（estrogen receptor β1，ERβ1）基因轉染乳腺癌MDA-MB-231細胞后對p53基因表達和細胞凋亡的影響，探討ERβ1在乳腺癌中的生物學作用。
方法應用脂質體法將ERβ1真核表達質粒轉染至乳腺癌MDA-MB-231細胞中，分別用熒光實時定量PCR法、Western blot法檢測轉染前、后細胞中ERβ1與p53 mRNA和蛋白表達的變化，流式細胞儀檢測細胞凋亡率。細胞生長曲線顯示轉染前、后細胞增殖能力的改變。
結果轉染外源性ERβ1真核表達質粒后，MDA-MB-231細胞中ERβ1及p53 mRNA和蛋白表達明顯增強（P lt;0.01）; 細胞凋亡率明顯增加（P lt;0.01），增殖能力明顯減弱（P lt;0.01）。
結論在乳腺癌中，ERβ1可以通過上調p53基因表達促進乳腺癌細胞凋亡，從而抑制乳腺癌細胞的增殖。
