| Project Title: | Reinforcing one-carbon metabolism via folic acid/Folr1 promotes beta-cell formation |
| Project Summary: | Diabetes can be caused by an insufficient beta-cell mass. Here, we performed a genetic screen in a zebrafish model with beta-cell loss to identify pathways promoting beta-cell regeneration. We found that both folate receptor 1 (folr1) overexpression and treatment with folate intermediates, i.e. tetrahydrofolic acid (THF) or folinic acid stimulated beta-cell differentiation in zebrafish. Treatment with these folate intermediates also stimulated beta-cell differentiation in neonatal pig islet cultures, showing the effect could be translated to a mammalian system. In both zebrafish and neonatal pig islets, the increased beta-cell differentiation originated from ductal cells. Mechanistically, comparative metabolomics analyses of zebrafish in the basal state vs following -cell ablation and in un-treated vs folinic acid-treated zebrafish indicated beta-cell regeneration could be attributed to changes in the pyrimidine, carnitine and serine pathways. Overall, our results suggest evolutionary conserved and previously unknown roles of folic acid and one-carbon metabolism in the generation of beta-cell . |
