    Non-coding RNAs and exosomal ncRNAs in colorectal cancer by Yalda Zhoulideh

    Published 2025-02-01
    “…We focus on microRNAs (miRNAs), long non-coding RNAs (lncRNAs), circular RNAs (circRNAs), and exogenous ncRNAs and their roles in regulating key signaling pathways such as the Wnt/β signaling pathway. β-catenin, PI3K/Akt, and TGF-β. We also discuss the potential of ncRNAs and exogenous ncRNAs as diagnostic and prognostic biomarkers for CRC, as well as their potential as therapeutic targets for CRC. …”
