Multiomics Reveals IGF-1 c.258A > G Reduces Triacylglycerol Containing Medium-Chain Fatty Acid in Milk

Fatty acid composition of milk triacylglycerol (TAG) is important for neonatal growth. We previously identified a synonymous mutation widely distributed in human populations, IGF-1 c.258A > G, which decreased milk TAG content in gene-edited mice. So far, the acyl chain composition of affected TAGs, underlying molecular mechanism, and cross-species conservation remain unclear. Here, integrated…
