The diagnosis of AML-M6 does not impart by itself a worse prognos

The diagnosis of AML-M6 does not impart by itself a worse prognosis, and treatment decisions on this disease should be guided by well known AML prognostic factors. Leukemia (2009) 23, 2275-2280; doi:10.1038/leu.2009.181; published online 10 September 2009″
“Stem cell-based therapy using bone marrow stromal cells (MSCs) has been expected to be a promising therapy for neuronal regeneration. To repair the injured spinal cord, neuronal differentiation of MSCs before transplantation has a more satisfactory effect. Recently, neuronal differentiation of neural progenitor/stem cells by an intracellular delivery of a pVHL-derived synthetic peptide (VHL peptide) has been

shown. Here, we show that VHL peptide-delivered MSCs differentiated into neuron-like cells, and that engrafted VHL peptide-delivered MSCs more recovered the behaviors of the rats than that click here of nondelivered MSCs. Our result suggests that the use of VHL peptide-delivered MSCs would be a promising therapeutic strategy for repairing the injured spinal cord.

“Epigenetic code modifications by histone deacetylase inhibitors have recently been proposed as potential new therapies for hematological malignancies. Chronic lymphocytic leukemia (CLL) remains incurable despite the introduction of new treatments. CLL B cells are characterized by an apoptosis defect rather than excessive proliferation, but proliferation centers have been found in organs such as the bone marrow and lymph nodes. In this study, we analyzed gene expression modifications in CLL B cells after treatment with valproic acid (VPA), a well-tolerated anti-epileptic drug with HDAC inhibitory activity. CLL B cells obtained from 14 patients were treated in vitro with a concentration of 1 mM VPA for 4 h. VPA effects on gene expression were thereafter studied using Affymetrix technology, and some identified genes were validated by real-time PCR and western blot. We observed that VPA induced apoptosis by downregulating several anti-apoptotic genes and by upregulating pro-apoptotic genes. Furthermore, VPA significantly

increased chemosensitivity to fludarabine, flavopiridol, bortezomib, check details thalidomide and lenalidomide. VPA inhibited the proliferation of CpG/IL2-stimulated CLL B cells and modulated many cell cycle messenger RNAs. In conclusion, exposure of CLL B cells to VPA induced apoptosis, potentiated chemotherapeutic agent effects and inhibited proliferation. These data strongly suggest the use of VPA in CLL treatment, particularly in combination with antileukemia agents.
