Cancer cachexia is a complex syndrome marked by appetite loss, weakness, fatigue, significant weight loss, and depletion of both adipose and muscle tissue, driven by metabolic and inflammatory alterations caused by tumors. Cachexia is a critical contributor to poor cancer prognosis, often leading to reduced efficacy of treatments. (CJM) is a medicinal herb widely used in Asia, known for its anti-inflammatory and metabolic regulatory properties. However, its potential role in cancer cachexia has not yet been explored. This research aimed to explore the potential of CJM extracts (CJME) in mitigating cancer cachexia in both myotubes treated with CT26 conditioned medium (CM) and in a CT26-induced cancer cachexia mouse model. Our results demonstrated that CJME significantly decreased the mRNA and protein levels of muscle-specific E3 ubiquitin ligases Atrogin-1 and MuRF1 in myotubes exposed to CT26 CM. Furthermore, CJME notably enhanced the protein levels of myosin heavy chain (MyHC). In the mouse model of CT26-induced cancer cachexia, severe loss of muscle and fat was observed. however, CJME effectively countered this wasting and restored abnormal biochemical parameters such as CK, albumin, triglycerides (TG), cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) associated with cancer cachexia. Moreover, CJME reduced interleukin-6 (IL-6) levels in both CT26 CM-stimulated myotubes and the serum of CT26-induced cancer cachexia mice. The mechanism underlying these effects appears to involve the suppression of STAT3 activation by CJME. These findings suggest that CJME has potential as a therapeutic candidate in the management of cancer cachexia.
癌症恶病质是一种复杂的综合征,其特征为食欲减退、虚弱、疲劳、显著体重减轻以及脂肪和肌肉组织消耗,由肿瘤引起的代谢和炎症改变所驱动。恶病质是癌症预后不良的关键因素,常常导致治疗效果降低。(某中药材名称,暂用CJM指代)是一种在亚洲广泛使用的草药,以其抗炎和代谢调节特性而闻名。然而,其在癌症恶病质中的潜在作用尚未得到探索。本研究旨在探讨CJM提取物(CJME)在减轻用CT26条件培养基(CM)处理的肌管以及CT26诱导的癌症恶病质小鼠模型中的癌症恶病质方面的潜力。我们的结果表明,CJME显著降低了暴露于CT26 CM的肌管中肌肉特异性E3泛素连接酶Atrogin-1和MuRF1的mRNA和蛋白质水平。此外,CJME显著提高了肌球蛋白重链(MyHC)的蛋白质水平。在CT26诱导的癌症恶病质小鼠模型中,观察到肌肉和脂肪严重流失。然而,CJME有效地对抗了这种消瘦,并恢复了与癌症恶病质相关的异常生化参数,如肌酸激酶(CK)、白蛋白、甘油三酯(TG)、胆固醇、高密度脂蛋白(HDL)和低密度脂蛋白(LDL)。此外,CJME降低了CT26 CM刺激的肌管和CT26诱导的癌症恶病质小鼠血清中的白细胞介素-6(IL-6)水平。这些作用的潜在机制似乎涉及CJME对STAT3激活的抑制。这些发现表明,CJME在癌症恶病质的管理中具有作为治疗候选物的潜力。
