Erdafitinib has recently been approved for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma (UC). The current study aimed to evaluate whether erdafitinib inhibits the proliferation in UC inducing authophagy. Our data showed that erdafitinib demonstrated strong toxicity for the T24 and UMUC6 cell lines. Flow cytometry analysis showed that erdafitinib increased the proportion of G0/G1 phase in both T24 and UMUC6 cells. Additionally, Annexin V staining indicated that erdafitinib enhanced the apoptosis of UC cells. Meanwhile, the expression of apoptosis-related proteins was significantly elevated after treatment with erdafitinib. Transwell assay showed that erdafitinib significantly reduced T24 and UMUC6 cell migration and invasion. More importantly, western blot assay showed that erdafitinib induced the expression of autophagy-related proteins. Besides, GFP-LC3 transfection assay and electron microscopy examination showed that erdafitinib could partially diminish 3-methyladenine (3-MA) induced impairment of autophagy in UC cells. In summary, for the first time we showed novel data that erdafitinib inhibited UC cell malignant proliferation inducing cell autophagy.

: Intravesical bacillus Calmette-Guérin (BCG) is the gold standard immunologic agent for treating patients with high-grade non-muscle invasive bladder cancer (NMIBC). Nevertheless, relapse rates remain high and BCG unresponsive NMIBC often requires bladder removal. Preclinical data suggest that priming with percutaneous BCG vaccine could improve response to intravesical BCG.

The nucleus accumbens-associated protein 1 (NACC1) is a transcription factor constitutively expressed in the urothelium, where it regulates cell growth, senescence, autophagy, and epithelial-mesenchymal transition. microRNA (miRNA) constitutes a class of small non-coding RNAs which are involved in cell proliferation, differentiation, and progression of tumors. miRNAs and their target molecules are utilized for molecular diagnosis of urothelial carcinoma.

The connexin 26 (Cx26) gene encodes a protein involved in gap junctional intercellular communication and is a putative tumor suppressor. We constructed a Cx26 adenovirus vector (Ad-Cx26) and used it to infect human bladder cancer cell lines UM-UC-3, UM-UC-6, UM-UC-14, and T24. Infection with Ad-Cx26 suppressed the growth of these cell lines in vitro and prevented tumor formation in vivo.
