However, the molecular mechanism of IGBP1 overexpression is still unclear. In the present study, we used a microRNA (miRNA) array and TargetScan Human software to detect IGBP1-related miRNAs that regulate IGBP1 expression. The miRNA array analysis revealed more than 100 miRNAs that are dysregulated in early invasive adenocarcinoma. On the other hand, in silico analysis using TargetScan Human revealed 79 miRNAs that are associated with IGBP1 protein expression. Among the miRNAs selected by miRNA array analysis, six (miR-34b, miR-138, miR-374a, miR-374b, miR-1909, miR-3941) were also included among those selected by TargetScan analysis.Cancer sciencemiR-3941: A novel microRNA that controls IGBP1 expression and is associated with malignant progression of lung adenocarcinoma.PMC5378261JP 15K19045Sato THong JShiba-Ishii AKano JIijima TSakashita SKim YDai THusni RENoguchi MfalsemiR-3941: A novel microRNA that controls IGBP1 expression and is associated with malignant progression of lung adenocarcinoma.Immunoglobulin (CD79a) binding protein 1 (IGBP1) is universally overexpressed in lung adenocarcinoma and exerts an anti-apoptotic effect by binding to PP2Ac.
