Abstract 1872
Background
Cancer is a group of the devastating disease having worldwide distribution, characterized by persistent proliferation or regeneration of cells. Breast cancer is a type of cancer that involves breast tissue and is one of the leading causes of deaths in women.
Methods
The current study was designed to determine the expression level of BCRP encoded by ABCG2 gene has a central role in the pharmacokinetics of both xenobiotic and drugs as well as contributes to multidrug resistance in cancer therapy. Quantitative real-time PCR was used to determine the gene expression level and analysis.
Results
The expression level of micro-RNA in up regulation of breast cancer resistance gene was determined as well as Foxo is playing a key role. Results showed that the relative Mir 140, Mir 145 and Micro 328 genes expression level are significantly higher expression level in breast cancer patient which down-regulate the ABCG protein. Src and mTOR genes are highly expressed in breast cancer patient. The data was analyzed statistically by using ANOVA and DMR test for significance.
Conclusions
Results concluded that higher expression of microRNA, mTor and FOXO down regulate the ABCG2 gene and stimulate the process of chemo-resistance, cell proliferation, apoptosis resistance.
