摘要 目的探讨FBXO44在乳腺癌中的表达及其与临床病理参数的关系,分析其与RAS、P53表达的相关性。方法用免疫组化检测正常乳腺组织、良性病变、导管原位癌和浸润性导管癌中FBXO44和RAS、P53的表达;用Western Blot检测乳腺癌细胞株(MCF-7、MDA-MB-231)和正常乳腺上皮细胞株(HBL-100)中FBXO44的表达。结果 (1)免疫组化示FBXO44在正常乳腺组织中阳性率为3%(1/30),其与良性病变间差异无统计学意义(P>0.05),FBXO44在良性病变、导管原位癌、浸润性导管癌中阳性率分别为13%(4/30)、50%(16/32)、78%(25/32),组间差异均有统计学意义(P<0.05);(2)FBXO44的表达与腋窝淋巴结转移、组织学分级及ER的表达相关(P<0.05);(3)FBX044的表达与P53的表达正相关(r=0.488,P<0.05),与RAS的表达无关;(4)Western Blot示FBXO44在乳腺癌细胞株MDA-MB-231中表达高于正常乳腺上皮细胞株HBL-100(P<0.05)。结论 FBXO44在乳腺癌中高表达可能与乳腺癌的发生发展及预后评估密切相关;FBXO44与P53的表达存在相关性。
