| Oral squamous cell cancer (OSCC) is one of the causes of death worldwide. The purpose of this project was to
define the restoring of microRNA-143 in HN-5 cells and discover molecular apparatuses responsible for the
anticancer processes. Firstly, expression levels of miR-143, K-Ras, MMP9 and C-Myc were evaluated in OSCC
tissues. Then, microRNA-143 was transfected into HN-5 cells. The cytotoxic effects of microRNA-143 on HN-5
cells were evaluated. To estimate the effects of microRNA-143 on cell migration, wound healing assay was done.
The expression levels of microRNA-143, K-Ras, MMP9, C-Myc, ADAMTS and CXCR4 were evaluated via the qRTPCR method. microRNA-143 mimic inhibited cell migration in HN-5 cell line. microRNA-143 mimic decreased
K-Ras, MMP9, C-My, ADAMTS and CXCR4 gene expression. microRNA-143 can inhibit HN-5 cells migration in
vitro by down-regulating the expression of invasion-linked genes. Hence, microRNA-143 can be a new diagnostic
biomarker and new therapeutic target for OSCC. |
