MKP-1 knockout mice show higher ERK activation and display reduced adiposity and protection against obesityReduction of MKP-1 using antisense oligonucleotide results in higher ERK activation and leads to reduced adiposityMKP-3 deficient mice demonstrate resistance to diet-induced obesityJIP1 deficient mice demonstrate resistance to diet-induced obesity. This evidence concerns the gene MAPK1 and obesity disorder.
