Abstract 4424: Cancer stem cells-related microRNAs have prognostic implications in non-small cell lung cancer

2017

Abstract Background: Lung cancer stem cells (CSCs) are a small population of stem-like cells that remains largely unknown. MicroRNAs (miRNAs) regulation of CSCs gene expression has been reported, constituting a promising therapeutic target. The aim of this study was to isolate and analyze differential expression of a set of miRNAs in tumorspheres from lung cancer cell lines and tumor tissue from resectable non-small cell lung cancer (NSCLC) patients and to determine the prognostic implications of these miRNAs in a cohort of resected-NSCLC patients. Methods: Lung CSC-related miRNAs (miR-145-5p, miR-188-5p, miR-218-5p, miR-34a-5p, miR-21-5p and miR-125a-5p) were analyzed in cells from seven N…
