ABSTRACT
Evidence showing the role of long non-coding RNAs (lncRNAs) in leukemogenesis have emerged in the last decade. It has been proposed that these genes can be used as diagnosis and/or prognosis biomarkers in childhood acute lymphoblastic leukemia (ALL). To know if lncRNAs are associated with early relapse and early mortality, a microarray-based gene expression analysis in children with B-lineage ALL (B-ALL) was conducted. Cox regression analyses were performed. Hazard ratios (HR) and 95% confidence intervals (95% CI) were calculated. LINC00152 and LINC01013 were among the most differentially expressed genes in patients with early relapse and early mortality. For LINC00152 high expression, the risks of relapse and death were HR 4.16 (95% CI 1.46-11.86) and HR 1.99 (95% CI 0.66-6.02), respectively; for LINC01013 low expression, the risks of relapse and death were HR 3.03 (95% CI 1.14-8.05) and HR 6.87 (95% CI 1.50-31.48), respectively. These results were adjusted by NCI risk criteria and chemotherapy regimen. The lncRNA-mRNA co-expression analysis showed that LINC00152 potentially regulates genes involved in cell substrate adhesion and peptidyl-tyrosine autophosphorylation biological processes. The results of the present study point out that LINC00152 could be a potential biomarker of relapse in children with B-ALL.
