SiBaoChongCao exhibited anti-fatigue activities and ameliorated cancer cachexia in mice

SiBaoChongCao (SBCC) is a functional food product containing fermentation of Acremonium terricola belonging to the Cordyceps genus. SBCC at 1 and 2 g kg^-1 for 20 days exhibited anti-fatigue activities such as increasing exhaustive swimming and running time of mice and increasing the strength of muscle. The increased muscle endurance in SBCC-treated mice might be related to enhancement of muscle cell growth and differentiation and improvement of muscle response to exercise training, as shown by an increase in muscle cross-sectional area and elevation of MHC, MyoD, MyoG and PGC-1α levels. And, SBCC at 1.5 g kg^-1 could ameliorate cancer-related cachexia such as ameliorating decrease in body temperature and inhibiting fat tissue atrophy. The anti-cachexia effects of SBCC might be related to inhibition of inflammatory cytokine IL-6 secretion and suppression of over-lipolysis and lipid over-utilization through inhibiting the activation of AMPK and p38 MAPK and down-regulating the level of UCP1.
