Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by selective death of motor neurons in the central nervous system. The main cause of the disease is still elusive but several mutations have been associated with the disease process. In particular, mutant SOD1 protein causes oxidative stress by activating glia cells and contributes to the motor neuron degeneration. KCHO-1, a novel herbal combination compound, contains 30% ethanol and the extracts of nine herbs that have been commonly used in traditional medicine to prevent fatigue or inflammation. In this study, we investigated whether KCHO-1 administration could reduce oxidative stress in an ALS model. KCHO-1 administration to ALS model mice improved the motor function and delayed the disease onset. Furthermore, we found that KCHO-1 administration reduced oxidative stress through gp91phox and MAPK pathway both in classically activated microglia and in the spinal cord of hSOD1G93A transgenic mice. These data suggest that KCHO-1 play as an effective therapeutic agent for ALS by reducing oxidative stress.
