PTBP1 and metabolic dysfunction-associated steatotic liver disease: A growing body of research has linked RBPs—such as human antigen R (HuR), sequestosome 1 (p62), polypyrimidine tract-binding protein 1 (PTBP1), and heterogeneous nuclear ribonucleoproteins (hnRNPs)—to lipogenesis and inflammation, both of which contribute to NAFLD through mechanisms involving transcriptional regulation, alternative splicing, RNA stability, polyadenylation, and subcellular localization.
