摘要
Abstract
Purpose This subject detected the expression of paper miRNA34a,c-myc gene and protein in adenocarcinoma of lung tissue,adjacent mucosa tissue and normal lung tissue exploring the relationship between the two and the clinical significance.Method The project mainly used the method of real-time fluorescent quantitative PCR (qRT-PCR),Western blot and immunohistochecical to detect the expression of miRNA34a and c-myc in normal tissue and adenocarcinoma of lung respectively.Result (1) lower expression of miRNA34a in lung adenocarcinoma tissue,lower than the adjacent and normal tissues (P ＜ 0.01),higher than the metastatic carcinoma group (P ＜ 0.01).C-myc is highly expressed in lung adenocarcinoma tissue,higher than the adjacent and normal tissues (P ＜0.01),lower than the metastatic carcinoma tissue (P ＜ 0.01).miRNA34a and c-myc beside carcinoma tissues and normal tissues also have significant difference between the statistical significance (P ＜ 0.05).(2) Differentiation of low and high there was no statistically significant difference between patients with lung adenocarcinoma (P ＞ 0.05).there were significant differences in the expression of miRNA34a and c-myc in the tissues of metastatic and non metastatic adnocarcinoma.(3)The positive expression of c-myc group of lung cancer patients was lower than that of the negative group (P ＜ 0.05),low expression of the survival time in miRNA34a group was significantly lower than that in high expression group,there was significant difference (P ＜ 0.01).Conclusion Expression of miRNA34a and c-myc both showed a negative correlation in adenocarcinoma of lung.关键词
