We also observed a decrease of OA in transgenic animals and a counterintuitive increase of 2-oleoyl-glycerol (2-OG) in Fat-1-HF mice (P < .01) as well as an increase of N-oleoyl-ethanolamine (OEA) in both groups of Fat-1 mice (genetic effect, P = .02) (Figure S7D-F). This evidence concerns the gene FAT1 and hydrops fetalis.
