ABSTRACT
Aim: In this study we attempt to indicate anti-carcinogenic influence of ether extracted metabolites of Streptomyces Levis sp. on gene expression in colon cancer
Background: Colon cancer is one of the most prevalent cancers worldwide. In recent decades, researchers have been seeking the treatment for cancer. Natural products are valuable compounds with fewer side effects in comparison to chemotherapy drugs
Methods: Secondary metabolites were extracted with the inoculation of bacterial sample in Mueller Hinton Broth. MTT assay was done to evaluate the cytotoxicity effect of metabolites on SW480 cells. qRT-PCR was performed to observe effects of metabolites on Bcl-2, P53, SOX2, KLF4, Beta-Catenin, SMAD4, K-ras, BRAF genes expression in colon cancer
Results: The metabolites exhibited cytotoxic effects on colon cancer in a dose/time dependent manner [P < 0.001]. After 48 h treatment, fold expression of Bcl-2, SOX2, Beta-catenin, K-ras, BRAF genes fold of expression were decreased, whereas P53, KLF4, SMAD4 genes were increased in treated cells [P < 0.001]
Conclusion: These findings indicate that ether extracted metabolites of Streptomyces Levis ABRIINW111 have anti-carcinogenic effects on colon cancer
