Popis: | SUMMARY Introduction: The JAK2V617F mutation has emerged in recent years as a diagnostic as well as a treatment target in patients with polycy- themia vera (PV) and essential thrombocythemia (ET). The disease phenotype is also influenced by other factors such as microRNA (miRNA) deregulation. The aim of this study was to investigate miR-125 expression level in these patients with those obtained from healthy control subjects and its correlation with JAK2 allele burden and laboratory findings. Methods: In total, forty patients with a clinical diagnosis of PV and ET were examined at the time of diagnosis. Ten healthy subjects were checked as controls. We performed JAK2 V617F allele burdens mea- surement and expression analysis of miR-125b-5p, miR-125b-3p, miR-125a-5p, and miR-125a-3p in leukocytes isolated from periph- eral blood by quantitative real-time polymerase chain reaction. Results: MiR-125b-5p and miR-125a-5p were upregulated in both patients with PV (P = 0.00 and P = 0.003, respectively) and ET (P = 0.02 and P = 0.002, respectively). In PV group, a significant correlation was observed between miR-125a-5p and platelet counts (P = 0.01, r = 0.531). The correlation between miRNA and JAk2 allele burden was not significant. Conclusion: In conclusion, our data indicate that other factors such as aberrant miR-125 expression may influence on the disease phe- notype in patients with PV and ET. |
