Chemotherapy-induced peripheral neuropathy (CIPN), a consequence of peripheral nerve fiber dysfunction or degeneration, continues to be a dose-limiting and debilitating side effect during and/or after cancer chemotherapy. Paclitaxel, a taxane commonly used to treat breast, lung, and ovarian cancers, causes CIPN in 59-78% of cancer patients. Novel interventions are needed due to the current lack of effective CIPN treatments. Our studies were designed to investigate whether nicotine can prevent and/or reverse paclitaxel-induced peripheral neuropathy in a mouse model of CIPN, while ensuring that nicotine will not stimulate lung tumor cell proliferation or interfere with the antitumor properties of paclitaxel. Male C57BL/6J mice received paclitaxel every other day for a total of four injections (8 mg/kg, i.p.). Acute (0.3-0.9 mg/kg, i.p.) and chronic (24 mg/kg per day, s.c.) administration of nicotine respectively reversed and prevented paclitaxel-induced mechanical allodynia. Blockade of the antinociceptive effect of nicotine with mecamylamine and methyllycaconitine suggests that the reversal of paclitaxel-induced mechanical allodynia is primarily mediated by the 7 nicotinic acetylcholine receptor subtype. Chronic nicotine treatment also prevented paclitaxel-induced intraepidermal nerve fiber loss. Notably, nicotine neither promoted proliferation of A549 and H460 non-small cell lung cancer cells nor interfered with paclitaxel-induced antitumor effects, including apoptosis. Most importantly, chronic nicotine administration did not enhance Lewis lung carcinoma tumor growth in C57BL/6J mice. These data suggest that the nicotinic acetylcholine receptor-mediated pathways may be promising drug targets for the prevention and treatment of CIPN.
化疗引起的周围神经病变(CIPN)是周围神经纤维功能障碍或退化的结果,在癌症化疗期间和/或之后仍然是一种剂量限制性且使人衰弱的副作用。紫杉醇是一种常用于治疗乳腺癌、肺癌和卵巢癌的紫杉烷,在59%-78%的癌症患者中会导致CIPN。由于目前缺乏有效的CIPN治疗方法,需要新的干预措施。我们的研究旨在调查尼古丁是否可以预防和/或逆转CIPN小鼠模型中紫杉醇引起的周围神经病变,同时确保尼古丁不会刺激肺肿瘤细胞增殖或干扰紫杉醇的抗肿瘤特性。雄性C57BL/6J小鼠每隔一天接受一次紫杉醇注射,共注射四次(8 mg/kg,腹腔注射)。急性(0.3-0.9 mg/kg,腹腔注射)和慢性(每天24 mg/kg,皮下注射)给予尼古丁分别逆转和预防了紫杉醇引起的机械性异常性疼痛。用美加明和甲基lycaconitine阻断尼古丁的抗伤害感受作用表明,紫杉醇引起的机械性异常性疼痛的逆转主要由7型烟碱乙酰胆碱受体亚型介导。慢性尼古丁治疗还预防了紫杉醇引起的表皮内神经纤维丢失。值得注意的是,尼古丁既没有促进A549和H460非小细胞肺癌细胞的增殖,也没有干扰紫杉醇诱导的抗肿瘤作用,包括细胞凋亡。最重要的是,慢性尼古丁给药并没有增强C57BL/6J小鼠Lewis肺癌肿瘤的生长。这些数据表明,烟碱乙酰胆碱受体介导的途径可能是预防和治疗CIPN的有前景的药物靶点。
