CAKI-1

CAKI-1 (亦称ATCC HTB-46) 是人类肾透明细胞癌皮肤转移细胞系^[1]，最初是分离自一名49岁的白人男性肾癌患者^[2]。

特徴

Caki-1细胞中高表达的基因345个，而低表达的基因则有217个^[3]。CAKI-1细胞的染色体倍性在三倍体范围内，并且不存在Y染色体，因为Y染色体的缺失在雄性肿瘤细胞系中并不罕见。除染色体N9和N19以外，所有的染色体都拥有2或3个拷贝。Caki-1细胞有许多微绒毛、发育充分的高尔基体与内质网、细小的线粒体及少许微丝，目前并没有在细胞内发现任何病毒颗粒。

科研用途

有学者提议将其作为近端肾小管上皮组织的模型，因为细胞在培养过程中，可以形成具有功能性及高度分化的肾组织形态、生理及生化特征的极化层 (polarized layer) ^[4]。有研究指出Caki-1是转移性肾亮细胞癌（英语：Clear cell renal cell carcinoma）的常用模型，当其携带着野生型vhl抑癌基因时，它就能在无胸腺裸鼠中产生清晰可见的肿瘤^[5]。这些细胞高表达血管内皮生长因子^[6]（特别是在氧气浓度低的情况^[7]）的特征就是肾亮细胞癌（英语：Clear cell renal cell carcinoma）的标志。
