摘要: Bladder cancer (BC) is the ninth most malignant tumor worldwide. Some BC patients will develop muscle-invasive (MIBC), which has a 5-year survival rate of approximately 60% due to metastasis. As such, there an urgent need for novel therapeutic and diagnostic targets MIBC. Analysis antitumor microRNA (miRNA)-mediated networks effective strategy exploring prognostic markers in cancers. Our previous miRNA analysis revealed that miR-140-5p acts as cells. Here, we investigated regulation molecular pathogenesis. Procollagen-lysine, 2-oxoglutarate 5-dioxygenase 1 (PLOD1) was found be directly regulated by miR-140-5p, aberrant expression PLOD1 observed clinical specimens. High significantly associated with poor prognosis (disease-free survival: P = 0.0204; overall 0.000174). Multivariate showed independent factor (hazard ratio 1.51, 0.0099). Furthermore, downregulation siRNAs specific inhibitor decreased cell aggressiveness. Aberrant closely In summary, present study may potential marker target BC.
