摘要 目的探讨腺癌、鳞癌、黏液性囊腺瘤、慢性胰腺炎和正常胰腺组织中胰腺癌相关基因的表达。方法回顾性收集2012年1月至2017年4月期间于湖北医药学院附属东风医院肝胆胰外科住院行手术治疗的40例胰腺疾病患者的术中标本,其中腺癌、鳞癌、黏液性囊腺瘤、慢性胰腺炎和正常胰腺组织各8例。采用实时荧光定量PCR和基因芯片法检测5组组织中Beclin-1 m RNA和micro RNA(mi R)-216a的表达。对以上组织行原代细胞培养,分为空白对照组和PD98095组(加入PD98095抑制剂),采用Western blot法检测细胞中血管内皮生长因子(VEGR)与磷酸化细胞外调节蛋白激酶1/2(p-ERK1/2)的表达。结果与正常对照组比较,腺癌组和鳞癌组组织中Beclin-1 m RNA和mi R-216a的表达水平较低(P<0.05),腺癌组、鳞癌组、黏液性囊腺瘤组和慢性胰腺炎组组织中Beclin-1 m RNA和mi R-216a的表达水平比较差异无统计学意义(P>0.05)。与同类组织的空白对照组比较,腺癌组和鳞癌组加入PD98095后,细胞中p-ERK1/2和VEGF蛋白的表达水平下调(P<0.05),但黏液性囊腺瘤组、慢性胰腺炎组和正常对照组加入PD98095前后细胞中p-ERK1/2及VEGF蛋白的表达水平变化不大(P>0.05)。结论 Beclin-1 m RNA、mi R-216a和VEGF蛋白的表达与胰腺癌的发生发展可能有关。
