Pax4 Acts as a Key Player in Pancreas Development and Plasticity|
Comparative analysis of Pax4 and Arx mutants, as well as Arx/Pax4 double mutants, showed that islet subtype destiny is mainly directed by cross-repression of the Pax4 and Arx factors. Importantly, the ectopic expression of Pax4 in α-cells was found sufficient to induce their neogenesis and conversion into β-like cells, not only during development but also in adult rodents.
