| Open AccessUSP7 controls NGN3 stability and pancreatic endocrine lineage development
Tightly controlled NGN3 expression is essential for endocrine cell generation in the developing pancreas, with dysregulation leading to hyperglycemia in mice. Here they identify USP7 as a key post-translational regulator of NGN3 stability and show that this axis is required for endocrine development and beta-cell differentiation.
