Highlights: • We first demonstrated CXCL5 is highly expressed in human bladder tumor tissues and cells. • CXCL5 knockdown inhibits proliferation, migration and promotes apoptosis in T24 cells. • CXCL5 knockdown inhibits Snail, PI3K-AKT and ERK1/2 signaling pathways in T24 cells. • CXCL5 is critical for bladder tumor growth and progression. - Abstract: CXCL5 (epithelial neutrophil activating peptide-78) which acts as a potent chemoattractant and activator of neutrophil function was reported to play a multifaceted role in tumorigenesis. To investigate the role of CXCL5 in bladder cancer progression, we examined the CXCL5 expression in bladder cancer tissues by real-time PCR and Western blot, additionally, we used shRNA-mediated silencing to generate stable CXCL5 silenced bladder cancer T24 cells and defined its biological functions. Our results demonstrated that mRNA and protein of CXCL5 is increased in human bladder tumor tissues and cell lines, down-regulation of CXCL5 in T24 cells resulted in significantly decreased cell proliferation, migration and increased cell apoptosis in vitro through Snail, PI3K-AKT and ERK1/2 signaling pathways. These data suggest that CXCL5 is critical for bladder tumor growth and progression, it may represent a potential application in cancer diagnosis and therapy.
