In the present study, AntiGan reduced the viability/survival of human liver and colon cancer cells in vitro; AntiGan increased apoptosis in both cancer cell lines by regulating p53 and Bax and cleaved caspase-3 protein expression, suggesting that AntiGan is an effective chemotherapeutic compound in treating various types of tumors (Figure 8). The gene discussed is TP53; the disease is colonic neoplasm.
