Effects of the purified dry extract of fermented ginseng BST204 on muscle fiber regeneration

Abstract

Background: Sarcopenia and muscular dystrophy are two muscle diseases. In cancer patients, cancer cachexia induces continuous weight loss and muscle loss due to the disease itself or the use of anticancer drugs. Cachexia occurs in up to 80% of cancer patients. It is recognized as a direct cause of reduced quality of life, contributing to at least 20% of cancer-associated deaths and limiting therapeutic options for cancer patients. Cancer cachexia is associated with multiple chronic or end-stage conditions and develops similarly. There are various options for the treatment of cancer cachexia, but there are still many issues to be solved. Hence, to determine its potential to overcome the muscle wasting during cancer cachexia, we studied the effect of BST204, a refined dry ginseng extract, on muscle fiber regeneration.

Experimental procedure: We checked the muscle regeneration efficacy of BST204. First, BaCl2 and freeze injury models were selected to investigate muscle regeneration after BST204 administration. In addition, after inducing muscle differentiation of C2C12 cells, the efficacy of BST204 was analyzed. In this model, we analyzed the expression of the signal pathway (PI3K-AKT signal) by Western blot and imaging methods.

Results and conclusion: These results showed that BST204 induced muscle fiber regeneration in BaCl2 and freeze injury models. Also, we confirmed that BST204 could regulate the PI3K/AKT signaling pathway and regulate the differentiation of C2C12 cells. These results indicate that BST204 has the potential to facilitate the skeletal muscle regeneration during muscle wasting induced by various factors including cancer cachexia.
