Caki-2 is a human clear cell renal cell carcinoma (ccRCC) line that displays epithelial morphology and grows in adherent culture. These cells are a useful preclinical model to study renal cancer. They are relatively less sensitive to 5-fluorouracil and sorafenib (multi-kinase inhibitor of VEGFRs 1-3, PDGFR-b, and Raf-1) compared to Caki-1 cells. The Caki-2 cells have a loss-of-function mutation in the von Hippel-Lindau (VHL) tumor-suppressor protein and are known to form tumors in immunocompromised mice.
This cell line was established in 1971 from the primary tumor of a 69-year-old Caucasian male with clear cell carcinoma of the kidney.
