Roles of K(H)SRP in modulating gene transcription throughout cancer progression: Insights from cellular studies to clinical perspectives

Biochim Biophys Acta Rev Cancer. 2024 Nov;1879(6):189202. doi: 10.1016/j.bbcan.2024.189202. Epub 2024 Oct 22.

Abstract

The KH-type splicing regulatory protein (KHSRP), also known as KSRP, is an RNA-binding protein that regulates gene expressions through various mechanisms, including messenger (m)RNA degradation, micro (mi)RNA maturation, and transcriptional activity. KSRP has been implicated in a wide range of physiological and pathological processes, with emerging evidence highlighting its role in modulating diverse aspects of cancer behaviors. In this review, we provide a comprehensive overview of KSRP's clinical relevance and its multifaceted regulatory mechanisms in cancer. Our extensive pan-cancer analysis uncovers associations of KSRP with clinical outcomes and identifies cell cycle progression as a key signaling pathway correlated with KSRP expression. Furthermore, we identify miR-17-5p as critical miRNAs positively correlated with KSRP, and it is associated with poor survival in various cancers. Collectively, this review offers new insights into the potential of KSRP as a target for therapeutic strategies in cancer treatment.

Keywords: Cancer progression; KSRP; RNA-binding protein; mRNA stability; miRNA maturation.
