Abstract: BACKGROUND/OBJECTIVES: extract (AKE) could attenuate cisplatin-associated cachexia and nephrotoxicity in CT26 tumor-bearing mice. METHODS: Cancer cachexia was induced by subcutaneous CT26 cell inoculation in 6-week-old male BALB/c mice, followed by a 7-day tumor establishment period. Cisplatin was then administered intraperitoneally, and AKE (125 or 250 mg/kg/day) was given daily by oral gavage for 14 days. RESULTS: AKE administration significantly alleviated cisplatin-induced body weight loss and systemic inflammation, accompanied by preservation of skeletal muscle and adipose tissue mass, as well as increased myofiber cross-sectional area and adipocyte size. AKE markedly reduced serum inflammatory cytokines, blood urea nitrogen, and creatinine levels, indicating protection against cisplatin-induced renal injury. Mechanistically, AKE suppressed renal apoptosis through inhibition of mitogen-activated protein kinase signaling. In skeletal muscle, AKE attenuated muscle atrophy by modulating protein turnover pathways, including downregulation of muscle-specific ubiquitin ligases and restoration of Akt/mTOR and FoxO3a signaling. Furthermore, AKE mitigated adipose tissue wasting by suppressing AMP-activated protein kinase-dependent browning and restoring adipogenic signaling involved in lipid storage and differentiation. CONCLUSIONS: These findings demonstrate that AKE confers comprehensive protection against cisplatin-induced cachexia and nephrotoxicity by coordinately preserving muscle and adipose tissue and attenuating renal injury, suggesting its potential as a functional nutritional strategy to alleviate chemotherapy-associated tissue wasting.
