 Abstract

2-Methoxyestradiol (2-ME), once considered an inactive end metabolite of estradiol, has emerged as a very promising agent for cancer treatment.  2 ME was reported to inhibit the proliferation of cells in different tumour cell lines. But it is necessary to investigate the effect of 2ME on in vivo system.   So the present study was undertaken to evaluate the efficacy and safety of 2ME on in vivo mouse tumour model considering tumour growth rate with nature of vascular density, mouse survival rate and bone marrow toxicity. Tumour regression in response to different concentrations of 2ME was studied at different time intervals by morphometric analysis of tumor size.  A steady decrease in tumour growth was noted after the treatment of 0.1mg ME in tumour bearing mouse which was correlated with the gradual increase of mouse survival or life span. In addition, 0.1mg ME not only induced a strong anti-angiogenic response   by a decline in the number of blood vessels in the tumour but also protect bone marrow by inhibition of maximum numbers of affected cell with chromosomal aberrations. So 2-Methoxyestradiol may be applied as a novel therapeutic drug for cancer.


Key words: 2-Methoxyestradiol, angiogenesis, morphometric analysis, mouse tumour model, chromosomal aberrations
