title: Integrated bioinformatics analyses identify dysregulated miRNAs in lung cancer.
abstract: BACKGROUND
  Lung cancer is the most common cause of cancer-related death worldwide. MicroRNAs (miRNAs) play important roles in various biological processes, including cell development, proliferation, differentiation and apoptosis.
  
  
  METHODS
  In the current study, using miRNA expression profiles from the Gene Expression Omnibus (GEO) database, we used three independent tests: Wilcox test, t-test and Fisher's exact test to investigate miRNA's involvement in lung carcinogenesis.
  
  
  RESULTS
  Ten differentially expressed miRNAs were identified. Among them, miR-675 drew specific attention. Ingenuity pathway analysis of its target genes revealed its impact on cell death and cell cycle. It is possible that miR-675 contributes to the pathogenesis of lung cancer through its down regulation of the tumor suppressor gene RB1.
  
  
  CONCLUSIONS
  Our results suggest miR-675 may serve as a potential therapeutic target of lung cancer.
