摘要: Malignant glioma is the most common type of cancer in central nervous system, with highly invasive characteristics. The Rho-associated protein kinase (ROCK1) has been found to act as key regulator actin cytoskeleton reorganization, a process closely associated cell invasion. microRNA-145 (miRNA-145) recently shown suppressor several types tumor, including glioma. However, exact regulatory mechanism by which miR-145 inhibits still remains be uncovered. In this study, we report that level was significantly reduced tissues and human lines U87 U251, compared matched adjacent normal brain tissues. We then identified ROCK1 gene novel target miR-145. expression markedly upregulated tissues, well U251 cells. Moreover, inhibited further show transfection considerably ability cells, accompanied downregulation matrix metalloproteinase 2 9, an effect could attenuated overexpression ROCK1. conclusion, present study suggests can inhibit invasion, at least partially via RhoA/ROCK1 pathway. first ROCK1, miR-145, acts positive Therefore, may constitute promising for treatment.
