Abstract

Introduction and Aims: According to Globocan 2012, India along with United States and China collectively accounts for almost one third of the global breast cancer burden. India is facing challenging situation due to 11.54% increases in incidence and 13.82% increase in mortality due to breast cancer during 2008–2012. The current treatment modality has issues of drug resistance and side effects. Many anticancer drugs currently used clinically have been isolated from plant species hence, investigation of plant species as a source of experimental therapeutic agents, in treating cancer is currently gaining a lot of importance. One such naturally available plant extract Melaleuka Alternifolia (TTO) which belongs to the family of essential oils is a very good antibacterial, antifungal, antiviral, antiprotozoal and anti-inflammatory agent. But currently there is a lot of importance has been given for its anticancer effect. Hence our aim is to evaluate anticancer activity of Melaleuka Alternifolia on Breast cancer cell line (MDA MB) by MTT assay an in vitro method.
Material and Methods: Before the start of the study ethical clearance was obtained from Institutional Review Board. The cytotoxicity checked for Breast cancer cell line (MDA MB) and NIH 3T3 mouse fibroblasts which were used as a control in our current study. These cell lines were procured from NCCS Pune, India. 1. MTT solution preparation (stock solution): 5 mg in 1 ml of PBS. 2. Cell culture : The cell lines were maintained in 96 wells micro titer plate containing MEM media supplemented with 10% heat inactivated fetal calf serum (FCS), containing 5% of mixture of Gentamicin (10ug), Penicillin ( 100 Units/ ml) and Streptomycin (100µg/ml) in presence of 5% CO2 at 37ºC for 48-72 hours. 3. Cytotoxicity Assay: In vitro growth inhibition effect of test compound was assessed by calorimetric or spectrophotometric determination of conversion of MTT into Formazan blue by living cells.
Results: The results represent the mean of five readings. The IC50 value of tea tree oil for breast cancer cell line (MDA MB) after 48 hrs was 25µg/ml. Spearmans rho’s Correlation showed P value <0> Conclusion: TTO has a promising anticancer property against Breast cancer cell line (MDA MB) with its IC50 value 25µg/ml. Hence this TTO with its greater efficacy related to its anticancer activity can be brought to the level of clinical trials in the coming future.

Keywords: Cytotoxicity, MTT assay, MDAMB cell line, Tea tree oil.
