Popis: OBJECTIVES: Latex from Hevea brasiliensis (natural rubber tree primarily cultivated for its rubber particles) has no known primary metabolic function, although its biological role is as a plant defence system. The present study has evaluated specific anti‐proliferative effects of latex whole C‐serum and its subfractions, on human cancer cell lines. MATERIALS AND METHODS: Cell viability assay using MTT, DNA fragmentation assay and real‐time PCR were used to evaluate the cytotoxic effects of latex whole C‐serum and its subfractions on the cell lines. RESULTS: MTT assay revealed very low LC (50) values, 2.0 and 280 ng/ml, for DCS and DCP treatments, respectively. DCS was proven to be more potent compared to DCP, in conferring specific anti‐proliferative effects on the cancer cell lines. The study also indicated that anti‐proliferative activity of pre‐heated C‐serum fractions diminished significantly. CONCLUSION: Although noteworthy cell death was reported, DNA fragmentation assay and real‐time PCR confirmed that that induced by latex C‐serum subfractions was not promoted via the classical apoptotic signalling pathway.
