Antiadhesive and cytotoxic effect of Iranian snake venom on lung epithelial cancer cells.

BACKGROUND

Cancer is one of the major health problems worldwide. Hence, finding potent therapeutics from natural sources seems necessary. Snake venom of contains potential component with anticancer activities such as antiproliferation, migration, invasion, adhesion, and angiogenesis effect. Evaluation of cytotoxic and antiadhesive effect of venom on lung epithelial cancer tumor cell (TC-1) was the main aim of this study.

MATERIALS AND METHODS

Here, we purified snake venom of by fast protein liquid chromatography (FPLC) using Sephacryl S-200 hr column. The fractions collected and evaluated by SDS-PAGE analysis. The cytotoxicity and antiadhesive effect of crude venom and fractions on TC-1 cells were demonstrated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and adhesion assay, respectively.

RESULTS

Our results showed six fractions in FPLC diagram. crude venom and fractions showed dose-dependent cytotoxic effect on TC-1 cells. Fractions 2 and 5 showed high cytotoxic effect with high IC50 value (IC50 = 6 μg/ml for fraction 2 and IC50 = 7.3 μg/ml for fraction 5). Fractions 2 and 5 selected for analysis antiadhesive effect on TC-1 cells. Furthermore, our results showed that both fractions 2 and 5 had antiadhesive effect on TC-1 cells.

CONCLUSION

Because of potent cytotoxic and antiadhesive effect of fractions on lung epithelial cancer cell line, it could be promising tools for further analysis as anticancer therapeutic development.
