Abstract

Background and objectives: DNA hyper-methylation is an important aspect involved in carcinogenesis and cancer progression, which affects mainly CpG islands of DNA and causes inactivation of tumour suppressor genes. Therefore DNA hypermethylation status of the genomic DNA in both the transformed cancerous cell lines and in carcinogen-induced lung cancer was ascertained by analysis of expressions of certain major lung cancer specific tumour suppressor genes. The other objective was to examine if ultra highly diluted homeopathic drug, Condurango 30C, had ability to modulate DNA methylation. Methods: DNA methylation activity, if any, has been ascertained in H460-NSCLC cells in vitro and in BaP-induced lung cancer of rats in vivo, in respect of tumour suppressor genes like p15, p16, p18 and p53 by using PCR-SSCP analyses. The ability of modulation of DNA methylation, if any, by Condurango 30C was also verified against placebo control in a blinded manner. Results: Condurango 30C-treated DNA showed significant decrease in band-intensity of p15 and p53 genes especially in methylated condition, in vitro, at the IC50 dose (2.43µl/100µl). SSCP analysis of p15 and p53 genes in Condurango 30C-treated DNA also supported ability of Condurango 30C to modulate methylation state, in vitro. Inhibition of p15 hypermethylation was observed after post cancer treatment of rat with Condurango 30C. SSCP results gave a better indication of differences in band-position and single strand separation of p15 and p53 in Condurango 30C treated samples. Conclusion: Condurango 30C could trigger epigenetic modification in lung cancer via modulation of DNA hypermethylation but placebos could not.
