摘要
Bladder cancer (BC) invasion is a critical factor that impacts the prognosis and quality of life of patients. However, the underlying mechanisms of BC invasion is far from clear. Fibroblast growth factor 13 (FGF13), a non-secretory FGF, has been found to be ectopically expressed in various tumors and implicated in tumor development, but its potential association to BC has not been investigated. Here, we reported that the expression of FGF13A, one nucleolar isoform of FGF13, was downregulated in BC patients and negatively associated with tumor invasion. Additionally, we demonstrated that overexpression of FGF13A could inhibit the migration and invasion of BC 5637 and T24 cells. We also confirmed the localization of FGF13A in the nucleolus and its interaction with nucleoproteins NPM1 and UBP. Subsequently, we identified that the N-terminal region of FGF13A was essential for its nucleolus location and interaction with NPM1. Furthermore, we found that FGF13A inhibited the generation of nascent ribosomal RNA and suppressed the migration and invasion of BC cells through its N-terminal region. Our research establishes, for the first time, a correlation between the expression of FGF13A and the onset and progression of BC. This provides novel insights into the role of FGF13A in the development of BC.
