BIX―01294靶向组蛋白甲基转移酶G9a在小细胞肺癌患者中的应用研究 　　[摘要] 目的 探?BIX-01294靶向组蛋白甲基转移酶G9a在小细胞肺癌患者中的应用。 方法 选择2016年2～8月医院收治的小细胞肺癌患者50例，患者均行手术治疗，取小细胞肺癌病灶标本及相应癌旁正常组织标本，采用HE染色及免疫组化染色检测两种不同标本中BIX-01294靶向组蛋白甲基转移酶G9a表达情况。 结果 50例小细胞肺癌患者中，29例发生淋巴或远处转移，21例未发生转移。50例肿瘤相应癌旁3 cm以上的肺组织均为正常组织。G9a抑制剂BIX-01294在两种组织阳性表达率比较差异有统计学意义（P 　　[关键词] 小细胞肺癌；DNA异常甲基化；组化蛋白；Wnt信号通路；BIX-01294靶向组蛋白甲基转移酶G9a 　　[中图分类号] R734.2 [文献标识码] A [文章编号] 1673-9701（2017）04-0001-04 　　Study on the application of BIX-01294 targeted histone methyltransferase G9a in the patients with small cell lung cancer 　　WANG Dandan1 ZHU Danyan1 WANG Dan1 XU Wenzhen2 　　1.Department of Pharmacy， Taizhou Hospital of Zhejiang Province， Taizhou 318000， China； 2.Department of Thoracic Surgery， Sanmenwan Branch， the First Affiliated Hospital of Zhejiang University， Sanmen 317100， China 　　[Abstract] Objective To investigate the application of BIX-01294 targeted histone methyltransferase G9a in small cell lung cancer. Methods From February to August 2016， 50 patients with small cell lung cancer who were admitted to our hospital were selected. Patients were given surgical treatment. Small cell lung cancer specimens and the corresponding adjacent normal tissue specimens were collected. The expression of BIX-01294 targeted histone methyltransferase G9a in two different specimens was detected by HE staining and immunohistochemical staining. Results Of the 50 patients with small cell lung cancer， 29 patients had lymphatic or distant metastases and 21 had no metastases. In 50 cases of tumor， the lung tissues adjacent to the cancer 3 cm and above were normal tissues. The positive expression rate of G9a inhibitor BIX-01294 in two tissues was compared， and the differences were statistically significant（P 　　[Key words] Small cell lung cancer； DNA aberrant methylation； Immunohistochemical protein； Wnt signaling pathway； BIX-01294 targeted histone methyltransferase G9a 　　肺癌是临床上常见的恶性肿瘤，我国肺癌每年发病人数超过100万，并且以每年26.9%的速度迅速增长，虽然临床对于肺癌技术的治疗取得了较大的发展，但是患者5年生存率低于15%。因此，肺癌已经
