Brief Summary:This study in mice shows that insulin-like growth factor 2 (IGF2), encoded by an imprinted gene and expressed by placental endocrine cells, is essential for the adaptive changes in maternal glucose and lipid metabolism during pregnancy to promote fetal growth. Failure of this adaptive program during pregnancy also resulted in metabolic dysfunction of offspring mice later in their life.IGF2 has been longer known to be involved in the regulat...

Brief Summary: This exome-wide association study conducted in the UK Biobank cohort (n=454 787) and in two non-European cohorts, the Mexican MCPS cohort (n=141 046) and the Pakistani PGR cohort (n=37 800), identified a association between rare protein-truncating variants (PTVs) in the APBA1 and the BSN genes and adult-onset obesity, suggesting two new genes as possible causes for monogenic obesity. Rare PTVs in BSN were also associated with Type 2 di...
