PORTFOLIO | Prof. Makhafola’s research focuses on investigating plant extracts and phytocompounds for their ability to delay different carcinogenic processes, including suppression, reduction or inversion of carcinogenesis. The main aim is to discover lead compounds that can be developed as cancer chemoprevention and cancer chemotherapeutic agents by investigating the antihepatocarcinogenic and antinephrocarcinogenic effects of selected South African medicinal plants against mycotoxin (Aflatoxin B1, Ochratoxin A and Fumonisin) carcinogenesis. Fifty South African plant species have been identified with antioxidant, antifungal, antimycototic and antimycotoxigenic activities.In addition, ten plant species showed hepatoprotective effects against mycotoxin induced toxicity. The research is ongoing to evaluate the nephroprotective effects of some plant species. Additionally, through a collaborative project at the ARC-OVI, an additional thirty plants were assayed for their antimutagenic effects against aflatoxin B1, using various in vitro genotoxicity assays. Plant extracts with high anticarcinogenic activity (in representative cell lines, i.e., hepatocytes and kidney cells) will be selected for isolation of active compounds and possible future in vivo studies. |
