PTP4A3 and acute lymphoblastic leukemia: Analysis of bone marrow aspirate from T-ALL patients showed that PRL-3 mRNA expression was significantly higher in primary T-ALL (n = 174) compared to healthy donor samples (n = 72, GSE13159, p = 6.8e−10, Fig. 1a), although there was no significant difference found in PRL-3 expression between patients who achieved complete remission (n = 29) versus those that relapsed (n = 11) or suffered induction failure (n = 7, GSE14615, Fig. 1b).
