A-875

A-875是人类恶性黑色素瘤细胞系，最初是分离自一名40岁的人类女性黑色素瘤患者^[1]，对神经生长因子受体呈阳性反应，目前可用于建立动物研究模型。

科研用途

1983年，有科研人员已经从A875细胞细胞膜的辛基葡萄糖苷（英语：Octyl glucoside）提取物中，纯化了NGF受体。最终A875细胞膜的可溶性提取物和纯化的NGF受体所进行的亲和标记（英语：Affinity label）实验表明，存在于NGF受体的两种主要的肽都可以与125I-NGF特异性交联 (specifically cross-linked) ^[2]。1990年，有研究人员比较A875细胞和大鼠嗜铬细胞瘤（英语：Pheochromocytoma）细胞系PC12细胞中NGF受体的特性。最终发现NGF的结合增强了悬浊液中A875细胞和PC12细胞的NGF受体横向扩散，而NGF对任何细胞系的NGF受体分布均没有任何影响^[3]。2017年，有学者利用A875细胞进行测试，发现SOX4（英语：SOX4）通过激活NF-κB/p65信号通路，促进黑色素瘤细胞的迁移和侵袭，并且指出SOX4可能是治疗黑色素瘤的潜在靶标基因^[4]。
