Abstract

This study examined whether the supplementation of Salicornia herbacea L. (SH), a member of the Chenopodiaceae subfamily, affects tissue specific triglyceride (TG) accumulation and the peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) and peroxisome proliferator-activated receptor-γ (PPAR-γ) protein expressions of skeletal muscle in rats with a high-fat diet. Sprague-Dawley male rats were randomly divided into three groups: control normal diet group (CD), high-fat diet group (HD), and 5.0% SH supplemented high-fat diet group (SD). The weights of fat tissue of the SD group were reduced by approximately 25%(p<0.01), while the skeletal muscle weight of the SD group increased approximately 5% compared to those in the HD group (p<0.01). The serum and hepatic TG of the SD group decreased approximately 20% compared to those of the HD group (p<0.05). In the protein expression levels in the skeletal muscle, the PGC-1α and PPAR-γ expressions of the SD group were 1.5-folds higher than those of the HD group (p<0.01). From these results, SH supplementation contributes to the improvement of the serum and hepatic TG concentrations, and the PGC-1α and PPAR-γ protein expression levels in the skeletal muscle of fed a high-fat diet. Thus, SH supplementation was effective in reducing fat mass and increasing muscle mass.
