For total protein levels, CDH6 was highly expressed in ovarian (OVCAR3 and SKOV‐3) and renal (RCC4 and 786‐O) cancer cell lines except in CAKI‐1 and A‐2780, while CDH17 was expressed in all cell lines, with RCC4, 786‐O, and OVCAR3 exhibiting the highest amounts (Fig. 1A). The gene discussed is CDH6; the disease is cancer.
