Research Abstract

MicroRNAs miR-200c and miR-27b, both of which were down-regulated by HGF stimulation in cultured human head and neck squamous carcinoma cells (HNSCC), might play an important role in EMT mediated by ZEB1 and ECM degradation and HGF auto-activation mediated by ST-14/matriptase, respectively. Altered expression of these microRNAs directly regulated by HGF might contribute enhanced progressive and invasive characteristics of HNSCC by regulating the translation of HGF-induced functional molecules. We also confirmed that the expression of miR-182 depends on the cancer grade even in same Gleason pattern 4 of prostate cancer. Expression of miR-182 associated with Gleason grading system in biopsy sample may contribute to more accurate preoperative cancer risk evaluation.
