“Bone marrow stromal cells (BMSCs) and osteoclasts (OCs) confer multiple myeloma (MM) cell survival through elaborating factors. We demonstrate herein that IL-6 and TNF family cytokines, TNF alpha, BAFF and APRIL, but not IGF-1 cooperatively enhance the expression of the serine/threonine kinase Pim-2 in MM cells. BMSCs and OCs upregulate Pim-2 expression in MM cells largely via the IL-6/STAT3 and

NF-kappa B pathway, respectively. Pim-2 short interfering RNA reduces MM cell viability in cocultures with BMSCs or OCs. Thus, upregulation of Pim-2 appears to be a novel anti-apoptotic mechanism for MM cell survival. Interestingly, the mammalian target of rapamycin inhibitor rapamycin further suppresses the MM cell viability in combination with the Pim-2 silencing. The Pim inhibitor (Z)-5-(4-propoxybenzylidene) thiazolidine-2,

4-dione and the PI3K inhibitor LY294002 cooperatively enhance MM cell death. The Pim inhibitor suppresses 4E-BP1 phosphorylation along with the reduction of Mcl-1 and c-Myc. Pim-2 may therefore become a new target for MM treatment. Leukemia (2011) 25, 1182-1188; doi:10.1038/leu.2011.60; published online 8 April 2011″
“The dopamine D3 receptor learn more gene (DRD3) is considered being one of the candidate genes contributing to the development of tardive dyskinesia (TD). In a recent meta-analysis with mixed ethnicities, only a barely positive association was found between the functional DRD3 Ser9Gly polymorphism and TD in patients with schizophrenia (OR = 1.17; 95% CI: 1.01-1.37; p = 0.041). To further evaluate the controversial association between the polymorphism and TD using only Japanese subjects, we tested the association in a case-control design. We also conducted a meta-analysis including

8 studies with 3 East Asian populations (Japanese, Chinese, and Korean). In our Japanese case-control NF-��B inhibitor sample (43 with TD/157 without TD), we found no association between the DRD3 Ser9Gly polymorphism in schizophrenia and TD (genotype: p = 0.92; allele: p = 1.00). Furthermore, no significant difference in the mean AIMS score among the three genotypic groups was observed in our sample. The meta-analysis comprising 1291 East Asian subjects also showed no association between the polymorphism and TD; the Mantel-Haenszel pooled OR for TD among carriers of the DRD3 Ser9Gly of the eight Asian studies was 0.94(95% CI: 0.78-1.12). Overall, our results suggest that the DRD3 Ser9Gly polymorphism may not confer susceptibility to TD in East Asian populations. Given that the Ser9Gly variant may play a putative role in the DRD3 function, further studies on the DRD3 are warranted. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
