Toll-Like Receptor 4, 2, and Interleukin 1 Receptor Associated Kinase4: Possible Diagnostic Biomarkers in Myelodysplastic Syndrome Patients.

BACKGROUND

Myelodysplastic syndrome (MDS) is a clonal hematologic disorder that requires the integration of morphologic, cytogenetic, hematologic, and clinical findings for a successful diagnosis. Trying to find ancillary tests such as biomarkers improve the diagnosis process. Several studies showed that a disordered immune system is associated with MDS. The chronic activated innate immune system, particularly the Toll-like receptors (TLRs) pathway could be involved in the induction of the inflammation.

MATERIALS AND METHODS

In the present study, we investigated the expression of , and in bone marrow (BM) of MDS patients, the leukemia group, and the healthy group. For this purpose, we assessed the expression of , and by real time-PCR.

RESULTS

In line with new findings, we demonstrated that the expression of , and significantly increased in MDS BM compared with the healthy group. Moreover, expression raised significantly in MDS patients compared with other studied hematologic neoplasms. Also, the expression levels of and significantly increased in MDS in comparison to some studied non-MDS malignancies ( ˂ 0.05). Receiver operating characteristics (ROC) analysis and area under the curve (AUC) suggested that the expression of , and (AUC = 0.702, AUC = 0.75, and AUC = 0.682, respectively) had acceptable diagnostic values to identify MDS from the other understudied leukemias.

CONCLUSION

Overall, the expression of , and could be potential biomarkers for discriminating MDS from some hematologic disorders.
