The inhibitory effect of amygdalin on the growth and differentiation markers E- and N-cadherin in renal cell carcinoma (RCC) cells was also demonstrated via the application of 10 g/mL amygdalin to the RCC cell lines A498, Caki-1, and KTC-26 for a period of 24 h or 2 weeks in vitro [35]. This evidence concerns the gene CDH2 and renal cell carcinoma.
