目的構(gòu)建雌激素受體（ER）亞型ERα/ERβ不同表達狀態(tài)的人乳腺癌細胞株MCF-7，觀察其生物學(xué)特性。方法采用RNA干擾技術(shù)沉默ERα或ERβ基因表達，獲得不同ERα或ERβ表達狀態(tài)的MCF-7細胞株。 運用MTT法、流式細胞術(shù)、RT-PCR法、雙層軟瓊脂集落形成實驗和體外細胞黏附實驗方法檢測細胞增殖、凋亡、體外成瘤和黏附能力。結(jié)果構(gòu)建穩(wěn)定表達ERαlow/ERβhigh或ERαhigh/ERβlow的MCF-7細胞株。 ERα基因沉默后，細胞生長減慢，受阻于G0～G1期，細胞凋亡增加，體外成瘤能力和黏附能力減弱； ERβ基因沉默后，細胞生長加快，S期細胞比例增加，細胞凋亡受到抑制，體外成瘤能力增強，而黏附特性無變化。 結(jié)論ERα基因沉默可抑制腫瘤的形成； 而ERβ基因沉默可促進腫瘤生長、侵襲和轉(zhuǎn)移。 調(diào)節(jié)ERα/ERβ表達狀態(tài)可能會成為一種有效的乳腺癌治療手段。
