Caution, this is an AI generated summary based on literature. This may have errors. ?

MIR452, a microRNA, has been found to be upregulated in both colorectal cancer (CRC) and dextran sulfate sodium (DSS)-induced mouse colitis tissues [PMC6826374]. It has been shown to regulate two VEGFA-VEGFR2-mediated signaling pathways, namely VEGFR2-SRC-PTK2 and VEGFR2-KRAS-BRAF-MAPK [PMC6826374]. Through these pathways, MIR452 has been found to regulate cell growth, cell migration, and angiogenesis in CRC cells via the VEGFA-VEGFR2 pathway [PMC6826374]. Additionally, when cells were co-transfected with a MIR452 mimic, the luciferase intensity was reduced by approximately 15% [PMC6826374].
