GPR107 Deficiency in Diabetic Nephropathy
2026-09-08
Xu et al. identify GPR107 as a regulator of AT1R internalization in podocytes, connecting impaired clathrin-mediated endocytosis with Ca2+-CREB signaling, collagen IV accumulation, and diabetic nephropathy progression. The study provides a mechanistic framework for interpreting extracellular-matrix remodeling and designing calcium-focused follow-up assays, while its animal and cell models leave important questions about therapeutic transferability.
