Abstract
Objective To explore the preliminary significance of overexpressed MUC-1 mRNA in the pathogenesis of lung adenocarcinoma. Method Total RNAs of 23 paired fresh lung samples and lung adenocarcinoma samples were extracted by routine Trizol way. After total RNAs were transcribed into cDNA, the expression of MUC-1 gene was detected in these samples by real-time PCR. Finally, the correlation of MUC-1 expression with the pathogenesis of lung adenocarcinoma was analyzed. Result Compared with normal lung tissues, the expression of MUC-1 in 20( 87% ) lung adenocarcinoma samples was markedly increased. Compared with early and mid-stage lung adenocarcinoma samples,. the overexpressed MUC-1 in late stage lung adenocarcinoma samples was increased by 2.2 folds. In addition, compared with primary lung adenocarcinoma samples without lymph node metastasis, MUC-1 mRNA was increased in primary lung adenocarcinoma samples with lymph node and distant metastasis ( 2.5 folds). Conclusion Overexpressed MUC-1 may participate in the pathogenesis of lung adenocarcinoma.
