Caspase 3/7 assays confirmed ∼40–60% increase in apoptotic activity in not only sensitive MIP and RKO CRC cells, but as well the resistant MIP/5FU and RKO/5FU cells following incubation with peptide-NT and 5 μM 5-FU for 24 hrs (Fig. 6A). The gene discussed is CASP3; the disease is colorectal carcinoma.
