Description
We examined the microRNAs (miRNAs) expressed in chronic lymphocytic leukemia (CLL) and identified miR-150 as the most abundant, but with leukemia-cell-expression levels that varied among patients. CLL cells that expressed ZAP-70 or that used unmutated IGHV each had a median expression-level of miR-150 that was significantly lower than that of ZAP-70-negative CLL cells or those that used mutated IGHV. In samples stratified for expression of miR-150, CLL cells with low-level miR-150 expressed relatively higher levels of forkhead box P1 (FOXP1) and GRB2-associated binding protein 1 (GAB1), genes with 3 UTRs having evolutionary-conserved binding sites for miR-150. High-level expression of miR-150 could repress expression of these genes, which encode proteins that may enhance B-cell receptor (BCR) signaling, a putative CLL-growth/survival signal. Also, high-level expression of miR-150 levels was a significant independent predictor of longer treatment-free-survival (TFS) or overall survival (OS), whereas an inverse association was observed for high-level expression of GAB1 or FOXP1 for OS. This study demonstrates that expression of miR-150 can influence the relative expression of GAB1 and FOXP1 and the signaling potential of the B-cell receptor (BCR), thereby possibly accounting for the noted association of expression of miR-150 and disease outcome.

Description
GM-CSF signaling was previously reported to have a negative effect on a murine model of (8;21)-induced leukemia. Gene expression profiling of MigR1 (Mig) control and RUNX1-ETO (RE), the oncofusion protein generated from t(8;21), murine Lin-/c-Kit+ hematopoietic stem/progenitor cells (HSPCs) was conducted to further elucidate the mechanisms mediating the negative effect induced by GM-CSF signaling in t(8;21) cells,

Description
The purpose of this study was to identify putative downstream targets of the transcription factor ZIC2 in the mouse embryo. The results indicate loss of NODAL pathway expression, consistent with the observed phenotype of right isomerism in heart, lungs and viscera.

Description
Mesenchymal stromal cells (MSCs), which have immunosuppressive and trophic abilities that are induced by inflammatory cytokines, have emerged as a promising option for cell-based therapy. The cytokine profiles vary substantially across different diseases and stages of disease progression, which has been shown to influence the curative properties of MSCs. Our knowledge about how MSCs respond systemically to cytokines is still limited. Here, we individually stimulated MSCs in vitro with IFN-?and used RNA-Seq to analyze their expression profiles.
