RESUMO
Function of cellular prion protein (PrP(c)) in cancer progression has not been elucidated yet. Ectopic expression of PrP(c) increases the invasion and migration of breast cancer cell line, MCF-7 cells. Overexpressed PrP(c) increases matrix metalloprotease-9 (MMP-9) expression by enhancing association of NF-κB in promoter of MMP-9 gene and ERK signaling in MCF-7 cells. Whereas, silencing of PrP(c) by siRNA suppresses ERK activation and MMP-9 expression resulting the down-regulation of MD-MB231 cell migration and invasion. Overall, these results suggest that PrP(c) contribute the breast cancer invasion and migration via MMP-9.
