title: Therapeutic effects of a recombinant mutant of the human ciliary neurotrophic factor in a mouse model of metabolic syndrome.
abstract: Metabolic syndrome (MS) is highly prevalent in developed countries and becoming a serious worldwide public health issue. In this study, we established a MS model by feeding male C57BL/6J mice with a high-fat diet (10%) for 18.5 weeks, studied the therapeutic effects of a recombinant mutant of the human ciliary neurotrophic factor (rhmCNTF) 0.1 (C-0.1) or 0.3 (C-0.3) mg x kg(-1) per day subcutaneously or pair feeding (PF, which mice were restricted to the same amount of food as eaten by C-0.3 treated mice) in MS mice. After 10 days treatment, rhmCNTF reduced obesity related indices, ameliorated glucose and lipid metabolism abnormality, and enhanced insulin sensitivity. In addition, liver function and antioxidant ability of MS mice were improved by rhmCNTF. Pair feeding revealed the same effects as C-0.3 on obesity related indices and insulin sensitivity, but aggravated hepatic steatosis and hepatic function. The results suggest that rhmCNTF could serve as an effective therapeutic agent for MS and related diseases.
