They play important roles in tumorigenesis and are considered tobe potential diagnostic and prognostic biomarkers with various cancers. MiR-200c and miR-9 are regulatory elementsthat can have dual impacts as oncogenes and/or tumor suppressor genes. MiR-200c regulates two transcription factors,ZEB1 and ZEB2, while miR-9 is a regulatory factor for the E-cadherin protein which has a critical function in cell-celljunctions and is inhibited by two transcription factors ZEB1 and ZEB2. In this study, expression levels of miR-200cand miR-9, ZEB-1, ZEB-2 and E-cadherin were assessed in 30 non-small cell lung cancers (NSCLCs) by real-timeqPCR. MiR-9 was down-regulated significantly in tumor tissues compared to normal adjacent tissues, while there wasno significant change in expression level of miR-200c. On the other hand, ZEB1 demonstrated significant increaseand ZEB2a decrease at the mRNA level. These results indicate roles for miR-9 and ZEB1 in genesis of lung cancer,although clinico-pathological associations were not evident. Further studies are necessary to assess implications fortreatment of lung cancer.}, keywords = {MicroRNAs,miR-9,miR-200c,non-small cell lung cancer}, url = {https://journal.waocp.org/article_88621.html}, eprint = {https://journal.waocp.org/article_88621_7bd8f28cc4bd920dec14e39407ddb141.pdf} }
