Results
This study aimed to evaluate the possible anticancer effects of some natural venom compared with a synthetic anticancer drug 5-Flurouracil (5-FU) as a positive control. The evaluation parameters include cell viability, oxidant/antioxidant system analysis and the expression of some genes related to apoptosis by RT-PCR technique.
The oxidant/antioxidant system was assessed by measuring lipid peroxidation end-product malondialdehyde (MDA), nitrite/nitrate levels by product of NO and glutathione peroxidase (GPX) enzyme in the cancer cell lines as oxidative stress marker.
Cell viability:
SRB assay of cytotoxicity:
In order to evaluation the cellular responses in MCF-7 and Caco-2 cells. The cells were treated with Naja h. venom, Leurius q. venom, Apis m. venom and 5-FU at concentrations ranging from 0.0µg/ml to 100µg/ml for 48 hours. The viability % and IC50 of each concentration was calculated in tables (5 to 9) and the IC50 data has been summarized at table (10)

The highest percentage of toxicity was observed Apis m. venom followed by Naja h. venom, finally Leurius q. venom and compared with 5-FU toxicity.
2. In Caco-2 case,
3. The highest percentage of toxicity was observed Apis m. venom followed by Naja h. venom, finally Leurius q. venom and compared with 5-FU toxicity.
