ABSTRACT
AIM:
To investigate the effect of tyrosine kinase inhibitor imatinib mesylate on the PTEN signaling pathway and the cell invasion in K562 cells.METHODS:
K562 cells were treated with different concentrations of imatinib mesylate. After different time periods, the mRNA levels of BCR/ABL, PTEN and FAK were detected by real-time fluorescent quantitative PCR (FQ-PCR) to analyze their relationships. The protein level of FAK was detected by immunocytochemistry. The cell invasive ability was examined by Transwell (Boyden chamber) assay.RESULTS:
In the initial 36 h, the expression level of PTEN mRNA was up-regulated and the FAK mRNA was down-regulated with the reduction of BCR/ABL fusion gene expression and the cell invasive ability of K562 cells was inhibited by 2 µg/mL imatinib mesylate. 48 h later, the PTEN mRNA expression level decreased and the FAK mRNA expression level was elevated with the restore of BCR/ABL fusion gene. BCR/ABL mRNA level presented a positive correlation with PTEN mRNA expression level, and a negative correlation with FAK mRNA.CONCLUSION:
Tyrosine kinase inhibitor imatinib mesylate can regulate PTEN/FAK pathway and inhibit the leukemia K562 cell invasive ability via restraining BCR/ABL fusion gene.
