Anticancer potential of Nymphaea nouchali Brum flowers against Ehrlich ascites carcinoma cell lines.

BACKGROUND

Nymphaea nouchali Brum is exotic and medicinal plant in India.

AIM OF THE STUDY: The main of this study is to evaluate the anticancer properties of Nymphaea nouchali Brum flowers against Ehrlich ascites carcinoma (EAC)-induced Swiss albino mice.

MATERIALS AND

METHODS

The anticancer properties of Nymphaea nouchali Brum dry and fresh methanol extracts was investigated using EAC in Swiss albino mice. After inoculation of EAC cells into mice, treatment with NNDM flower extract (200 and 400 mg/kg) and standard drug 5-Fluorouracil (20 mg/kg) was continued for 9 days. The evaluation of the effect of drug response was made by the study of tumor growth response including increase in lifespan, the study of hematological parameters, biochemical estimations, and antioxidant assay of liver tissue compared to EAC control. The viability of cancer cell lines (such as HeLa, MCF-7, and MDA-MB 231 cells) was evaluated by 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) assay.

RESULTS

Therefore, from the results of the present study, it can be concluded that NNDM exhibited significant antitumor activity against EAC in Swiss albino mice. The effect of NNDM on viability of cancer cell lines (such as HeLa, MCF-7, and MDA-MB 231 cells) was evaluated by MTT assay, apoptosis in HeLa cell lines was evaluated by DNA laddering assay, HeLa cells treated with NNDM exhibited a characteristic "ladder" pattern after separation of the fragments by agarose gel electrophoresis and subsequent visualization, by ethidium bromide staining. NNDM exhibited a significant effect on cell viability.

CONCLUSIONS

Based on results, it was concluded that NNDM exhibited cytotoxic effect on cancer cells and, from DNA laddering assay, it can be concluded that NNDM-induced apoptosis in EAC cells.
