Niban apoptosis regulator 1 promotes gemcitabine resistance by activating the focal adhesion kinase signaling pathway in bladder cancer.

ABSTRACT: Although intravesical gemcitabine (GEM) chemotherapy (IGC) can effectively reduce the recurrence risk of non-muscle invasive bladder cancer (NMIBC), the development of GEM resistance may occur and result in cancer recurrence and disease progression. Herein, a label-free proteomics approach was used to characterize the proteomic profiles of primary/post-IGC recurrent NMIBC. A total of 218 proteins were found to be differentially expressed in paired primary and post-IGC recurrent NMIBC. Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that multiple signaling pathways including "focal adhesion" were highly enriched in recurrent NMIBC. Niban apoptosis regulator 1 (NIBAN1) was identified as the top upregulated protein in recurrent NMIBC. Highly increased NIBAN1 expression was o
