Plantamajoside mitigates endoplasmic reticulum stress-mediated pancreatic β-cell apoptosis in type 2 diabetes <i>via</i> DNAJC1 upregulation

Diabetes mellitus (DM) is a metabolic disorder characterized by persistent hyperglycemia and other symptoms, which pose significant challenges to individual health, life expectancy, and public healthcare systems. The escalating global prevalence of diabetes underscores the need for innovative therapeutic interventions. In this article, we critically comment on the study by Wang <i>et al</i>, published in the <i>World Journal of Diabetes</i>, which elucidates the therapeutic potential of Plantamajoside (PMS) in type 2 DM (T2DM) management. The authors provide evidence for the mechanism of action of PMS in T2DM models, demonstrating prevention of endoplasmic reticulum stress and apoptosis of pancreatic β-cells <i>via</i> activation of DNAJC1. This manuscript provides a brief review of the pathogenesis of T2DM, explores the various roles of PMS in disease therapy in addition to the DNAJC-related apoptotic and autophagic functions, critically evaluates the experimental approaches employed by Wang <i>et al</i>, and provides recommendations for advancing future research.
