Proteomic analysis reveals that Polygonatum cyrtonema Hua polysaccharide ameliorates mice muscle atrophy in chemotherapy-induced cachexia.
In this study, researchers investigated the effects of Polygonatum cyrtonema Hua polysaccharide (PCP) on muscle atrophy caused by chemotherapy. They found that PCP, a compound derived from Polygonati Rhizoma herb, significantly reduced muscle loss and muscle fiber atrophy in mice. It also suppressed the decrease in immunoglobulin levels and the increase in pro-inflammatory factor interleukin-6 (IL-6). Proteomic analysis identified two primary targets of PCP: diacylglycerol kinase (DGKζ) and cathepsin L (CTSL). The study suggests that PCP regulates the autophagy-lysosome and ubiquitin-proteasome systems, providing a potential treatment for chemotherapy-induced muscle atrophy.
