Introduction: Protein and gene expressions are intensively profiled for potential biomarkers in diagnosis or prognosis of diseases. The correlation between corresponding protein and mRNA of a gene is important to establish whether transcript levels of a given gene can be used as proxies for the corresponding protein levels. mRNA profiling is more commonly utilised as this method is cheaper and the technology more advanced. Acute myeloid leukaemia (AML) is a heterogeneous group of malignant precursors of the myeloid lineage that leads to death if not treated. Cytokines and death receptors are commonly evaluated in this disease in search of potential biomarkers; however, the mRNA/protein correlations of these biomarkers are still unclear. Methods: Semi-quantitative expression of mRNA expression and protein levels of IL-1β, IL-18Rα, IL-6, TNF-α and DR5 were measured by conventional polymerase reaction (PCR) and flow cytometry in 11 cases of AML at diagnosis. Correlation in the intensity of the PCR amplicon and corre-sponding mean fluorescence intensity of protein was determined by Spearman’s rank correlation test. Results: None of the cytokines/death receptor was significantly correlated except IL-6 (Rs= -0.6287, p=0.038). Unexpectedly, this was also a significant negative correlation. Conclusion: For the majority of selected biomarkers in AML, whether secreted or surface-expressed, mRNA and protein expressions were not significantly correlated. The strong negative correlation for IL-6 is worth further investigation.
