Increased STAT5 activation in adult human ALL patients correlate with poor prognosis. (A) Shown are the relative levels of phospho-STAT5 (tyrosine 694/699) in cells from indicated human ALL cytogenetic subtypes (hyperdiploid, hypodiploid, immature B cell [IM], miscellaneous [Misc], no analyzable metaphases [NAM], Bcr-Abl [Ph+], pseudodiploid, diploid, t[11;14], t[4;11], t[8,14], t[8;22], and t[11;19]). Solid black bars represent the median and solid boxes represent the 25–75% range; dashed lines give ± 2 SD and open circles represent outliers. The number of samples for each subset is listed above the plot. (B) Bcr-Abl patients were separated into two equal groups representing higher (red line, n = 5) and lower (blue line, n = 6) levels of phospho-STAT5 (pSTAT5). All of these patients were subsequently treated with combination chemotherapy, including a tyrosine kinase inhibitor imatinib, and overall survival was determined. (P = 0.03, Log Rank [Mantle-Cox] test).
