circMAN1A2 as an Isoform‐Resolved Circular RNA Hub in Cancer

Cancer Science, Volume 117, Issue 9, Page 2345-2356, September 2026.
circMAN1A2 as an isoform‐resolved circular RNA hub in cancer. circMAN1A2 is generated by back‐splicing of MAN1A2 pre‐mRNA, with alternative circularization producing multiple isoforms, including the predominant circMAN1A2(2–5). Its mechanistic interfaces include miRNA‐associated regulation, RBP binding/proteostasis control, BSJ‐mediated RNA–RNA pairing,
