Reduced miR-105-1 levels are associated with poor survival of patients with non-small cell lung cancer.

ABSTRACT: Altered expression of microRNAs (miRNAs or miRs) contributes to lung carcinogenesis. The present study performed an in silico analysis of differentially expressed miRNAs in different peripheral blood samples from patients with various diseases vs. controls using the Gene Expression Omnibus (GEO) database data, and assessed miR-105-1 expression in 32 normal lung and 142 non-small cell lung cancer (NSCLC) tissue samples using reverse transcription-quantitative polymerase chain reaction. Survival data were calculated using Kaplan-Meier curves and a log-rank test. The stepwise forward Cox regression model was performed for univariate and multivariate analyses of independent predictor of overall survival (OS) of patients. The data on in silico and tissue microarray analyses of miRNA expression
