Earlier, Takato et al. demonstrated that myristic acid (14:0) markedly increased diacylglycerol kinase δ (DGKδ) concentration in mouse C2C12 myotubes of the congenital type 2 diabetes model; For other fatty acids examined, such as lauric (12:0), palmitic (16:0), and stearic (18:0) acids, no influence was detected. The gene discussed is DGKD; the disease is type 2 diabetes mellitus.
