The clinical outcome of children with high-risk relapsed B-cell precursor acute
lymphoblastic leukemia (BCP-ALL) is poor. The present study assessed the utility
and prognostic value of selected microRNA (miRNA/miR) in BCP-ALL. The changes in
the expression levels of these miRNAs regarding known gene lesions affecting
lymphoid development [early B-cell factor 1 (EBF1), ETS variant 6 (ETV6), IKAROS
family zinc finger 1 (IKZF1), paired box 5 (PAX5), cyclin dependent kinase
inhibitor (CDKN) 2A/CDKN2B, retinoblastoma 1 (RB1), pseudoautosomal region 1
(PAR1), B-cell translocation gene 1 protein (BTG1)] were analyzed. The following
miRNAs were analyzed: miR-24, miR-31, miR-128, miR-542, and miR-708. The present
study focused on patients with deletions of the IKAROS transcriptional factor
gene IKZF1, which is currently considered to be an independent negative
prognostic factor for ALL outcome. It was demonstrated that the expression level
of miR-128 was significantly lower in patients with IKZF1 deletion compared with
patients without IKZF1 deletion. Additionally, low expression of miR-542 was
associated with CDKN2A/B and miR-31deletions, and low expression of miR-24 was
associated with miR-31 deletion. Low expression of miR-31, miR-24, miR-708 and
miR-128 was associated with PAX5 deletion, high expression of miR-24 and miR-542
was associated with PAR1 deletion and high expression of miR-708 was associated
with ETV6 deletion. The expression of the selected miRNAs was not associated with
deletions of BTG1, EBF1 and RB1. These data, by emphasizing the association of
miRNAs expression level with microdeletions, may assist to elucidate ALL biology
and contribute to future studies on the possible applications of the miRNA
profile for diagnosis.
