Under our experimental conditions, there were no differences in the serum levels of insulin after 8 weeks of HF feeding as follows: wild-type mice fed normal diets, 0.84 ng/ml±0.21; wild-type mice fed HF diets, 1.14 ng/ml±0.14; IVA-PLA2-knockout mice fed normal diets, 1.22 ng/ml±0.10; IVA-PLA2-knockout mice fed HF diets, 0.94 ng/ml±0.33; n = 4–5. Here, INS is linked to hydrops fetalis.
