Background
Growing evidence has demonstrated that microRNAs have a major effect on development of different types of cancer including AML. The overexpression of miR-625 could decrease tumorgenesis of acute myeloid leukemia cell lines through Integrin-linked kinase signaling pathway and reducing the associated oncogenes. The
Conclusion
MiR-625 can be a promising approach to aid in the treatment of AML. However, further studies are required in this respect.
Methods
The KG-1 cell line was transfected with pLenti-III-premir625-GFP through viral method. Then, expression of miR-625 and genes were analyzed by quantitative PCR. Western blotting was used to evaluate for the protein level. Apoptosis was investigated by flow cytometry. Cell cycle analysis with PI and CCK-8 assay were performed to evaluate proliferation.
Results
KG-1 cells transfected with pLenti-III-pre mir625-GFP construct showed a significant increase in cell apoptosis. Gene expression of ILK and NF-κB were downregulated and AKT, c-fos, Caspase3, cyclin D1, KLF-4, OCT-4 and Nanog were upregulated but no alteration in GSK3 expression profile was observed. Downregulation of NF-κB and upregulation of Caspase 3 and p-β-catenin protein levels were indicated (p<0.05).
