Abstract MicroRNAs (miRNAs) play a vital role in regulating tumor progression. Dysregulated miR-136 expression was linked to the development of various human cancers. In the present study, we investigated the expression and relationship of miR-136 and COX2 in hepatocellular carcinoma (HCC) using relevant experiments, involving CCK-8, Transwell assay, and luciferase reporter assay. We demonstrated that miR-136 expression is obviously decreased in HCC tissues and cells, and negatively correlated with the expression of COX2 mRNA. In vitro assay revealed that overexpression of miR-136 significantly changed the expression of proliferation- and metastasis-related proteins and inhibited the proliferation, migration, More >

Abstract We recently found that SLC39A5 (ZIP5), a zinc transporter, is overexpressed in esophageal cancer. Downregulation of ZIP5 inhibited the proliferation, migration, and invasion of the esophageal cancer cell line KYSE170 in vitro. In this study, we found that downregulation of SLC39A5 (ZIP5) by interference resulted in a significant reduction in esophageal cancer tumor volume and weight in vivo. COX2 (cyclooxygenase 2) expression was decreased and E-cadherin expression was increased in the KYSE170K xenografts, which was caused by the downregulation of ZIP5. However, we did not find that the downregulation of ZIP5 caused a change in More >
