Abstract (original English)
DNA methylation was considered as prognostic information in some hematological malignancies. Previous studies have reported the in vitro and in vivo biology role of mesenchymal stem cells (MSCs) on leukemic cells. The aim of this study was to investigate the effect of MSCs on the promoter methylation status of hTERT as a catalytic subunit of telomerase enzyme. In the experimental study, the Molt-4 leukemic cells were co-cultured with MSCs for 7 days. At the end of the co-culture period, the Molt-4 cells were collected, DNA and protein were extracted. Then methylation specific-PCR and western blotting were done for evaluating the hTERT gene promoter methylation status and cyclin D1 and hTERT protein expression, respectively. In the following, the flow cytometry was done for cell cycle distribution assay. It was found that MSCs resulted in a significant decrease in the cyclin D1 and hTERT protein expression levels. Also, MSCs caused changes in the methylation status of the CpG islands in the hTERT gene promoter region. The following results showed that MSCs caused a significant increase in the number of cells at G0/G1 phase and arrest the G0/G1 phase as well as decrease in the cell proliferation of Molt-4 cells. It is concluded that co-culture of MSCs with Molt-4 cells could be involved in changing the methylation status of hTERT gene promoter, cell cycle and hTERT protein expres
