Aberrant STAT5 and PI3K/mTOR pathway signaling occurs in human CRLF2-rearranged B-precursor acute lymphoblastic leukemia.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Adults and children with high-risk CRLF2-rearranged acute lymphoblastic leukemia (ALL) respond poorly to current cytotoxic chemotherapy and suffer unacceptably high rates of relapse, supporting the need to use alternative therapies. CRLF2 encodes the thymic stromal lymphopoietin (TSLP) receptor, which activates cell signaling in normal lymphocytes on binding its ligand, TSLP. We hypothesized that aberrant cell signaling occurs in CRLF2-rearranged ALL and can be targeted by signal transduction inhibitors of this pathway. In a large number of primary CRLF2-rearranged ALL samples, we observed increased basal levels of pJAK2, pSTAT5, and pS6. We thus characterized the biochemical sequelae of CRLF2 and JAK alterations in CRLF2-rearranged ALL primary patient samples via analysis of TSLP-mediated signal transduction. TSLP stimulation of these leukemias further induced robust JAK/STAT and PI3K/mTOR pathway signaling. JAK inhibition abrogated phosphorylation of JAK/STAT and, surprisingly, of PI3K/mTOR pathway members, suggesting an interconnection between these signaling networks and providing a rationale for testing JAK inhibitors in clinical trials. The PI3K/mTOR pathway inhibitors rapamycin, PI103, and PP242 also inhibited activated signal transduction and translational machinery proteins of the PI3K/mTOR pathway, suggesting that signal transduction inhibitors targeting this pathway also may have therapeutic relevance for patients with CRLF2-rearranged ALL and merit further preclinical testing.
