Semin Oncol:解充血药可以“高效”饥饿癌细胞

2017-11-22 Heather_z727译自 medicalxpress 来宝网

国家癌症研究所的研究人员们一直在研究可以提到有害化疗药物的无毒替代物,近期,研究人员们发现一种感冒药的效果非常好,名为n -乙酰半胱氨酸(NAC)的药物是一种膳食补充剂,作为解充血药给孩子驱寒散瘀。

国家癌症研究所的研究人员们一直在研究可以提到有害化疗药物的无毒替代物,近期,研究人员们发现一种感冒药的效果非常好,名为n -乙酰半胱氨酸(NAC)的药物是一种膳食补充剂,作为解充血药给孩子驱寒散瘀。

现在,在美国临床试验表明这种非处方药物可以有效抑制肿瘤基质,打破癌细胞扩散的基础。研究结果发表在肿瘤学研讨会中,这一研究证实了长期以来的理论基础,那就是癌症细胞正在持续加强MCT4的存在,蛋白质负责带给他们能量,并从周围细胞中形成乳酸。病人服用高剂量的NAC后,研究人员观察到蛋白水平下降了80%以上,这大大减少了癌细胞养活自己的能力。

英国索尔福德大学的研究人员表示:“在实验室细胞培养中,我们看到了MCT4附近蛋白质的完全减少,如果可以在人类乳腺癌患者体内达到这样的效果,那无疑是治疗乳腺癌的一大飞跃。”

在此次研究中,研究人员招募了等待手术的12名乳腺癌参与者,患者每日接受最大程度的每日剂量,研究人员在手术之前和期间分别进行肿瘤切片组织检测,标记关键的生物标记物,包括MCT4和K167,测量对象。结果显示,K167水平下降了25%,MCT4水平减少了大约80%。

“高水平的基质MCT4与癌症的发展有着密不可分的关系,这一结果非常令人兴奋,而且最重要的是,这种非处方药物的价格非常便宜,这也在极大程度上减轻了癌症患者的负担。”
