目的研究肝X受体(liver X receptors,LXRs)在乳腺癌中的表达及其对乳腺癌MCF-7细胞增殖的影响。方法采用免疫组化法检测LXRs在人乳腺癌组织中的蛋白表达;采用LXR激动剂T0901317处理人乳腺癌MCF-7细胞,流式细胞术检测BrdU标记MCF-7细胞的增殖情况。结果①LXRα和LXRβ在乳腺正常组织基本不表达,但LXRα在不同乳腺癌病变(导管原位癌和浸润性导管癌)中表达增高(P<0.05),在浸润性导管癌尤为明显;LXRβ在不同乳腺癌病变中不表达。②T0901317(10μM)处理明显抑制MCF-7细胞的增殖率(P<0.05)。结论乳腺癌组织LXRα蛋白表达明显增高,激活LXRα能够显著抑制MCF-7细胞的增殖。
