摘要
目的:明确磷脂酶PLA2-ⅠB在正常小鼠胃组织中的细胞表达类型,检测PLA2-ⅠB在人胃癌组织中的表达情况。方法:利用Northern印迹验证PLA2-ⅠB在小鼠胃组织中的表达;利用原位杂交明确PLA2-ⅠB在正常小鼠胃组织中的细胞表达类型;利用反转录PCR检测14例人胃癌组织中PLA2-ⅠB的表达情况。结果:PLA2-ⅠB主要表达在小鼠腺胃的主细胞;与癌旁相比,PLA2-ⅠB的表达在93%的人胃癌标本中显著下降。结论:磷脂酶PLA2-ⅠB在胃癌组织中的表达下降。
Objective: To investigate the expression profile of phospholipase A2-ⅠB(PLA2-ⅠB) in mouse glandular stomach and to detect the alteration of PLA2-ⅠB expression in human gastric cancer samples. Methods: Northern blot was applied to determine the PLA2-ⅠB expression in mouse glandular stomach. In situ hybridiza- tion was utilized to identify the expression pattern of PLA2-ⅠB in mouse glandular stomach. Reverse transcription PCR was performed in 14 pairs of human samples from gastric cancer tissues and corresponding normal tissues. Results: PLA2-ⅠB was mainly expressed in chief cells of mouse glandular stomach. Furthermore, PLA2- ⅠB expression was significantly decreased in 93% human gastric cancer tissues when compared with corresponding adjacent normal tissues. Conclusion: PLA2-ⅠB expression was decreased in human gastric cancer.
