RNA editing from A to I, facilitated by ADARs, plays a crucial role in post-transcriptional processing, particularly in lung adenocarcinoma (LUAD) via the regulation of miR-1251-5p.
Experiments using various methods like RT-qPCR and animal assays indicated that edited miR-1251-5p significantly inhibits tumor growth and metastasis compared to its unedited form.
The edited miR-1251-5p achieves its anti-cancer effects by inactivating the Wnt signaling pathway through the suppression of genes like TCF7, MYC, and CCND1.
