1 · What the graph read from it

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.

2 · The registry

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

Interactions between MEK1/2 inhibitors and the dual Abl/Src kinase inhibitor dasatinib (BMS-354825) were examined in chronic myeloid leukemia (CML) cell lines and primary specimens. Cotreatment of K562 or LAMA cells with subtoxic or marginally toxic concentrations of PD184352 (or U0126) and dasatinib synergistically potentiated mitochondrial damage, caspase activation, and apoptosis. Similar interactions were observed in CD34(+) cells from one CML patient-derived but not in a normal human CD34(+) bone marrow cell specimen. These interactions were associated with multiple perturbations in survival signaling pathways, including inactivation of Bcr/Abl, STAT5, and ERK1/2; down-regulation of Bcl-x(L) and Mcl-1; and dephosphorylation/activation of Bim. They were also associated with BAX/BAK conformational change, mitochondrial dysfunction, and caspase activation. Bim knockdown by shRNA suppressed BAX and BAK conformational change and protected cells from dasatinib/PD184352 lethality. Conversely, K562 cells ectopically expressing Mcl-1 or Bcl-x(L) were significantly less susceptible to dasatinib/PD184352 toxicity. Notably, the dasatinib/PD184352 regimen was active against leukemic cells exhibiting various forms of imatinib mesylate resistance, including Bcr/Abl overexpression, Lyn activation, and several Bcr/Abl kinase domain mutations (eg, E255K, M351T), but not T315I. Together, these findings suggest that strategies combining dasatanib with MEK1/2 inhibitors warrant further investigation in Bcr/Abl(+) malignancies, particularly in the setting of imatinib mesylate-resistant disease.
