Abstract

The study was conducted to assess the effects of creatine pyruvate (Cr-Pyr) on lipid and protein metabolism in male rats. Healthy adult male Sprague-Dawley (SD) rats (40) were randomly assigned to control group (CG) and 3 experiment groups (EG) administrated with 750 (EG₁), 1500 (EG₂), or 3000 (EG₃) mg/kg Cr-Pyr daily for 42 d. The fat mass in male rats of EGs was lower and relative muscle weight was significantly higher in EG₂ and EG₃ than CG. The content of serum HDL-C and hepatic TC was significantly lower in EG₂, and male rats of EG₃ had significantly lower hepatic TG as compared to those in CG. Supplementation of male rats with 3000 mg/kg Cr-Pyr significantly decreased the serum leptin concentration but increased insulin. Serum IGF-1 was thought statistically not significantly difference but its level elevated in EGs compared to CG. The expressions of HSL in fat and peroxisome proliferators-activated receptor a mRNA in liver were enhanced in EG₂ and EG₃ than CG. Supplementation of Cr-Pyr resulted in a significant increase in muscle protein content in EGs. Hepatic GPT was increased in EGs, but no effect on hepatic GOT activity. Supplementation of Cr-Pyr resulted in significant increase in muscle myogenin mRNA expression, while muscle mRNA abundance of myostatin (MSTN) was unaffected. The results described herein demonstrated that supplementation of Cr-Pyr was accompanied by significant elevated levels of lipolysis and increased muscle protein synthesis through the regulation of various metabolic parameters in male rats.
