FGFR1 and hepatocellular carcinoma: UCA1 (lncRNA urothelial carcinoma-associated 1) plays a pivotal role in the tumorigenesis of HCC by acting as a ceRNA for miR-216b, leading to the suppression of FGFR1 (fibroblast growth factor receptor 1) expression and the activation of the MAPK/ERK signaling pathway [80].
