Here, we performed a PR:PROJECT_SUMMARY genetic screen in a zebrafish model with beta-cell loss to identify pathways PR:PROJECT_SUMMARY promoting beta-cell regeneration. We found that both folate receptor 1 (folr1) PR:PROJECT_SUMMARY overexpression and treatment with folate intermediates, i.e. tetrahydrofolic PR:PROJECT_SUMMARY acid (THF) or folinic acid stimulated beta-cell differentiation in zebrafish. PR:PROJECT_SUMMARY Treatment with these folate intermediates also stimulated beta-cell PR:PROJECT_SUMMARY differentiation in neonatal pig islet cultures, showing the effect could be PR:PROJECT_SUMMARY translated to a mammalian system. In both zebrafish and neonatal pig islets, the PR:PROJECT_SUMMARY increased beta-cell differentiation originated from ductal cells. PR:PROJECT_SUMMARY Mechanistically, comparative metabolomics analyses of zebrafish in the basal PR:PROJECT_SUMMARY state vs following -cell ablation and in un-treated vs folinic acid-treated PR:PROJECT_SUMMARY zebrafish indicated beta-cell regeneration could be attributed to changes in the PR:PROJECT_SUMMARY pyrimidine, carnitine and serine pathways. Overall, our results suggest PR:PROJECT_SUMMARY evolutionary conserved and previously unknown roles of folic acid and one-carbon PR:PROJECT_SUMMARY metabolism in the generation of beta-cell .
