MMP2 and prostate carcinoma: Furthermore, DU145R80, a ZOL-resistant prostate cancer cell line, expresses p38 MAPK-dependent survival pathway accompanied with an enhanced potential for epithelial-mesenchymal transition (EMT) and the increased expression of metalloproteases MMP-2/-9 compared to its parental cell line, suggesting the essential role of p38 MAPK in acquiring chemoresistance of prostate cancer cells [62].
