Canonical and non-canonical miRNA degradation shapes state transitions and stemness in breast cancer
Target-directed microRNA degradation (TDMD) is an emerging post-transcriptional mechanism that controls miRNA turnover, yet its role in human cancers remains largely unexplored. Here, we combine CRISPRi-mediated ZSWIM8 depletion, miRNA-seq, and AGO2-eCLIP to define the TDMD landscape across breast cancer subtypes. We i...
