Description:
The aim of our perspective observational study was identify a fast molecular biomarker of tumorigenic-proliferative haematological disorders at on set using a non-invasive method. At this end, to better discriminate between myeloproliferative or lymphoproliferative hematological disease, from May to July 2014, we collected peripheral blood mononuclear cells (PBMCs) from patients at the first medical examination and without drug therapy. The patients were divided into groups on the basis of the diagnosis. Group 2 (n=8) included patients suffered from mixed disorders such as myeloproliferative neoplasms (MPD) associated to monoclonal gammopathy of undetermined significance (MGUS). Group 3 (n=8) included patients with only MGUS, group 4 included 9 patients with only primary myelofibrosis (M). Healthy donors (Group 1, n=16) were considered as normal subject or calibrator in molecular analysis. Their PBMCs were used to perform relativegene expression profile of a transcriptome involved in apoptotic control, stem-cell differentiation, immune network, inflammation and leukemogenesis, in order to detect whether these may serve to label the patient groups. A multigene expression assay (47 genes) was carried out with the TaqM,an® Low Density Array Fluidic card. In Group 3 (MGUS), 6 genes were differentially expressed (BMI-1, FLT3, FZD1, FZD5, ICAM1, IMP3). Also, we compared variance, main value for each gene in each group and T-test that showed a significant differential expression pattern (p
