Exosomes containing miR-152-3p targeting FGFR3 mediate SLC7A7-induced angiogenesis in bladder cancer.

ABSTRACT: Bladder cancer (BCa) is a prevalent malignancy with a poor prognosis. SLC7A7 has been linked to BCa progression and angiogenesis, but its specific role remains unclear. We established a SLC7A7-knockdown BCa cell line to investigate its effects on angiogenesis. In vivo experiments assessed tumor vascularization, while in vitro studies explored exosome involvement. MiRNA sequencing identified miR-152-3p as a key regulator. Further investigation using dual-luciferase reporter assays, qRT-PCR, and Western blot revealed that miR-152-3p inhibits the expression of FGFR3 by binding to its 3' UTR. Meanwhile, functional assays, including angiogenesis assays, Transwell assays, and wound healing assays, were performed to evaluate the effects of miR-152-3p on angiogenesis. We confirmed the significant
