Plasma insulin concentrations in Dgat1^+/+ (+/+), Dgat1^+/- (+/-) and Dgat1^-/-(-/-) mice fed on a chow diet (A) or a high fat diet (B) immediately before administration of glucose in the glucose tolerance tests, and also 30 min after administration of glucose in the high fat-fed mice (C). Results are means of 12 values, except that there were 6 female Dgat1^-/- mice fed on the high fat diet. * P < 0.05; ** P < 0.01; *** P < 0.001 compared to Dgat1^+/+ mice of the same sex.
