Popis: Acute lymphoblastic leukemia (ALL) cells depend on the microenvironment of the host in vivo and do not survive in in vitro culture. Conversely, the suppression of non-malignant tissues is one of the leading characteristics of the course of ALL. Both the non-malignant suppression and malignant cell survival may be partly affected by soluble factors within the bone marrow (BM) environment. Here, we aimed to identify proteins in BM plasma of children with ALL that may contribute to ALL aggressiveness and/or the microenvironment-mediated survival of ALL cells. LBMp (leukemic bone marrow plasma) at the time of ALL diagnosis was compared to control plasma of bone marrow (CBMp) or peripheral blood (CPBp) using a cytokine antibody array. The cytokine antibody array enabled simultaneous detection of 79 proteins per sample. Candidate proteins exhibiting significantly different profiles were further analyzed and confirmed by ELISA. mRNA expression of one of the candidate proteins (TIMP1) was studied using quantitative reverse transcriptase polymerase chain reaction (qRTPCR). The cytokine antibody array experiments identified 23 proteins that differed significantly (p
