FACS analysis of Stat3/5 signaling reveals sensitivity to G-CSF and IL-6 as a significant prognostic factor in pediatric AML: a Children's Oncology Group report.

Signal transducer and activator of transcription 3 (Stat3) and Stat5 are critical signaling intermediates that promote survival in myeloid leukemias. We examined Stat3 and Stat5 activation patterns in resting and ligand-stimulated primary samples from pediatric patients with acute myeloid leukemia. Phosphorylated Stats were measured by FACS before and after stimulation with increasing doses of granulocyte-colony stimulating factor or IL-6.

Stat3 signaling in acute myeloid leukemia: ligand-dependent and -independent activation and induction of apoptosis by a novel small-molecule Stat3 inhibitor.

Acute myeloid leukemia (AML) is an aggressive malignancy with a relapse rate approaching 50%, despite aggressive chemotherapy. New therapies for AML are targeted at signal transduction pathways known to support blast survival, such as the Stat3 pathway. Aberrant activation of Stat3 has been demonstrated in many different malignancies, including AML, and this finding is frequently associated with more aggressive disease.

Genome-wide atlas of gene expression in the adult mouse brain.

Molecular approaches to understanding the functional circuitry of the nervous system promise new insights into the relationship between genes, brain and behaviour. The cellular diversity of the brain necessitates a cellular resolution approach towards understanding the functional genomics of the nervous system. We describe here an anatomically comprehensive digital atlas containing the expression patterns of approximately 20,000 genes in the adult mouse brain.
