Abstract

Background: NUCLEOSTEMIN plays a critical role in controlling proliferation and self-renewal of stem cells and cancer cells.Thus, inhibition of NUCLEOSTEMIN expression could be a potent therapeutic approach in cancer treatment. In the present study, the effects of NUCLEOSTEMIN gene silencing in K562 cell line were studied.Materials and Methods: In this experimental study, after transfecting NS-specific SIRNA into K562 cells, changes in NUCLEOSTEMIN gene expression pattern were determined by semi- quantitative reverse transcription polymerase chain reaction (RT-PCR). Trypan blue exclusion test, MTT assay, and fluorescent microscopy were used to evaluate the growth inhibition and APOPTOSIS of K562 cells, respectively. Flow-cytometery was utilized for evaluating the effects of NUCLEOSTEMIN gene silencing on cell cycle.Results: The results showed the high expression of NUCLEOSTEMIN gene in K562 cells. NS-siRNA transfection into K562 cells at 200 nM inhibited the NUCLEOSTEMIN mRNA level up to 55% after 48 hours when compared to corresponding control cells. Forty eight hours after transfection, the cell growth decreased up to 33.7%. In addition, the silencing of NUCLEOSTEMIN induced G1 cell cycle arrest. Furthermore, fluorescent microscopy assays indicated that APOPTOSIS occurred 48 hours after silencing NUCLEOSTEMIN gene expression.Conclusion: Noticing the potent growth inhibitory and apoptotic effects of NUCLEOSTEMIN SIRNA in human myeloid leukemia K562 cells, silencing this gene can be a potential target for inhibiting K562 cells as the stem cell model of chronic myeloid leukemia.
