Advance in glutathione S-transferase kappa 1 / 中南大学学报(医学版)

Glutathione S-transferase kappa 1 (GSTK1) is a key regulator for adiponectin secretion and multimerization.In Caenorhabditis elegans,GSTK1 is involved in energy production and lipid metabolism.Meanwhile,the GSTK1 level is negatively correlated with obesity.It may alleviate the endoplasmic reticulum stress-mediated downregulation of adiponectin.Moreover,a polymorphism in human GSTK1 promoter is related with insulin secretion and fat deposition.Therefore,GSTK1 might be a novel target for the treatment of insulin resistance and the relevant metabolic diseases.
