Dataset Summary
| Title | CBX4 stabilizes NEUROD1 through SUMO-ubiquitin crosstalk to delay β-cell senescence |
| Description | CBX4 expression is progressively lost in aged and diabetic pancreatic β-cells, correlating with cellular senescence. Mechanistically, CBX4 stabilizes NEUROD1 by promoting its SUMOylation at lysine 38, which antagonizes NEDD4-mediated ubiquitination. Stabilized NEUROD1 enhances insulin transcription and activates CaMKII signaling by suppressing Camk2n1 expression. This cascade preserves mitochondrial function and calcium homeostasis in β-cells. Thus, the STAT5A-CBX4-NEUROD1 axis represents a key protective pathway against β-cell aging and a potential therapeutic target for T2DM. |
