| Summary: | Cancer cells are abnormal cells that rapidly and excessively grow beyond their normal cell growth. From the total deaths worldwide, 13 percent were caused by cancer in 2005. The main types of cancers that lead to total death worldwide are; lung, stomach, liver, colon, and breast cancer. Breast cancer is the most common form of cancer affecting women in Malaysia while colon cancer is one of the most common malignancies in the world. Cancers can be treated by surgery, radiotherapy and chemotherapy. Approximately 50% of cancer patients receive chemotherapy. Currently, these anti cancer drugs have some limitations; low selectivity and specificity, producing toxic effects and development of multi-drug resistance in patients. To date, anticancer drugs from natural sources are widely studied because these drugs may be potent towards cancer cells and less toxic which may exhibit better therapeutic outcome as compared to existing anticancer drugs. Endophytes are microorganisms that live symbiotically in healthy tissues of living plants. The first and most significant anticancer agent discovered was paclitaxel. It is widely used in the treatment against breast cancer. Due to high demand of new natural anti-cancer agent, this research is developed to investigate the cytotoxic properties of local endophytic fungi. The crude extracts of endophytic fungal that have been used in this research include the extract of HAB2R1, HAB13R21, and HAB15L10. Interestingly, HAB15L10 appeared to be effective towards colon and breast cancer cells. The average IC50 value of HAB15L10 was 0.35µg/ml. This extract should be further studied due to its beneficial effects towards colon and breast cancer cells. |
