decrease in the viability of human bladder cancer cells T24inducing apoptosis of cancer cells by reducing the expression of the anti-apoptotic protein Bcl-2, increasing the expression of the pro-apoptotic protein Bax, inactivating caspase-3, caspase 9 and PARP, reducing the activity of mitochondria (limiting the activity of mitochondrial membranes). This evidence concerns the gene CASP3 and urinary bladder carcinoma.
