过去 25 年,在识别和表征调节铜的吸收、细胞内运输和输出的蛋白质方面取得了巨大进展。尽管膳食中需要微量的铜,但人类和其他哺乳动物需要足够量的这种金属来维持生长和发育。然而,铜也是癌细胞生长和增殖的限速营养素。与食物一起服用的口服铜螯合剂已被证明对动物和人类具有抗肿瘤和抗转移作用。最近的研究已经开始确定铜在致癌信号传导途径和抗肿瘤药物耐药性中的特定作用。在这里,我们回顾了细胞铜稳态的一般机制,并讨论了铜在癌症进展中的作用,强调了抗癌疗法开发中可能针对的代谢脆弱性。
The last 25 years have witnessed tremendous progress in identifying and characterizing proteins that regulate the uptake, intracellular trafficking and export of copper. Although dietary copper is required in trace amounts, sufficient quantities of this metal are needed to sustain growth and development in humans and other mammals. However, copper is also a rate-limiting nutrient for the growth and proliferation of cancer cells. Oral copper chelators taken with food have been shown to confer anti-neoplastic and anti-metastatic benefits in animals and humans. Recent studies have begun to identify specific roles for copper in pathways of oncogenic signaling and resistance to anti-neoplastic drugs. Here, we review the general mechanisms of cellular copper homeostasis and discuss roles of copper in cancer progression, highlighting metabolic vulnerabilities that may be targetable in the development of anticancer therapies.
