Abstract — Having various pathological and molecular subtypes with several causes, breast cancer is the most prevalent malignancy amongst women. Neurotransmitters and neuropeptides are triggers responsible for the growth of cancerous cells and metastasis through their specific receptors. These neurotransmitters and neuropeptides include catecholamines, γ-amino butyric acid, acetylcholine, serotonin, neuropeptide Y, neurotensin, substance P, and neurokinin A. Each of these substances raises the risk of breast cancer and metastases, which ultimately lead to the death of patients. The purpose of this review is to investigate the role of neurotransmitters and neuropeptides in breast cancer metastasis.

神经递质和神经肽在乳腺癌转移中的作用

摘要 — 乳腺癌具有多种病因和多种病理和分子亚型，是女性中最普遍的恶性肿瘤。神经递质和神经肽是负责癌细胞生长和通过其特定受体转移的触发器。这些神经递质和神经肽包括儿茶酚胺、γ-氨基丁酸、乙酰胆碱、血清素、神经肽 Y、神经降压素、P 物质和神经激肽 A。这些物质中的每一种都会增加患乳腺癌和转移的风险，最终导致患者死亡. 本综述的目的是研究神经递质和神经肽在乳腺癌转移中的作用。
