Babao Dan Alleviates Cancer Cachexia in Mice Via Inhibiting IL-6/STAT3 Signaling Pathway

Abstract

Background: Cancer cachexia is a common but severe condition that causes muscle wasting, body weight loss, and progressive functional impairment, affecting over 50% of cancer patients. Currently, there are no effective treatments that can alleviate cachexia, and hence the discovery of new therapeutics that can effectively prevent or even reverse cancer cachexia is crucial. Babao Dan (BBD) is a Traditional Chinese Medicine (TCM) formula that has been used clinically in combating various cancers, however, its therapeutic potential in alleviating cancer cachexia remains unexplored. Our current study aims to determine the anti-cachectic effects of BBD treatment in alleviating cancer cachexia, as well as determining the underlying mechanisms involved. Methods: Mouse models of cancer cachexia were induced via implantation of CT26 colon adenocarcinoma cells, and the anti-cachectic effects and mechanisms of BBD were determined via examinations of body weight and muscle mass, as well as serum and muscle markers of cachexia and muscle atrophy. Results: CT26 tumor implantation reduced in the rapid occurrence of cancer cachexia characterized by marked reductions in body weight and muscle mass, functional decrease in muscle function and accelerated deaths. BBD administration not only demonstrated robust anti-cachectic ability via preventing decreases in body weight, muscle mass, and muscle atrophy, but also markedly prolonged survival. The effects of BBD in alleviating cancer cachexia and its associated adverse effects were due to its ability in preventing the activation of IL-6/STAT3 signaling post-CT26 tumor implantation. Conclusion: Our findings demonstrated the robust ability of BBD in preventing cancer cachexia and alleviating the main cachexia-induced symptoms as well as prolonging survival via inhibiting activation of IL-6/STAT3 signaling pathway. Therefore, our study demonstrating the strong anti-cachectic effects of BBD in mice may provide a theoretical basis for the use of BBD as a safe and effective drug in the treatment of cancer cachexia.
