Project description:Male Sprague Dawley adult rats were subjected to a cervical hemisection at C2 (C2HS). Costal diaphragm (both ipsilesional and contralesional sides) were assessed under control conditions (sham surgery) and at 1 and 7 days post-C2HS. We used SA Biosciences Rat Skeletal Muscle Development and Disease RT2 Profiler PCR Array to quantitate gene expression of muscle atrophy and regeneration-relevant genes from the uninjured and injured tissues on the indicated sides and at the indicated timepoints post-lesion. qPCR gene expression profiling. Tissue was derived from the costal diaphragm from control animals, and from contralesional and ipsilesional sides at days 1 and 7 post-lesion. RNA was extracted from flash-frozen tissue (TRIzol reagent) and quantitated via spectrophotometry. Equal amount total RNA from each donor was pooled prior to gene expression analysis. N=3 or 4 rats per condition. Four genes in the array study appeared to undergo unphysiologic increases in expression following SCI: Mmp9, Leptin, activin A and alpha actinin. For these genes, expression levels in control tissue were detectable but extremely low, thus fold-increases following SCI are numerically exaggerated. Therefore, we cannot explicitly comment on the physiologic scale of this response

Project description:Murine macrophages were isolated from the lungs of mice given a pulmonary challenge with C. neoformans strain H99. Mice were either given a protective (H99γ) or a mock (HKCn) immunization prior to C. neoformans H99 challenge, and macrophages were isolated from the lungs of mice 24 hours, 3 days, or 7 days post-challenge using anti-CD11b microbeads according to the Miltenyi cell sorting system. We used SA Biosciences Toll-like Receptor PCR assay panel to quantitate gene expression of signal transduction factors in total RNA isolated from macrophages derived from immunized mice compared to non-immunized. qPCR gene expression profiling. Macrophages from 5 mice per group were pooled and assayed as indicated in the summary. Each experiment was performed 3 times and the resulting Ct values of each group from each experiment averaged prior to data analysis. TIme points were analyzed separately

Project description:The interaction of natural killer (NK) cells with dendritic cells (DC) results in reciprocal cell activation through the interaction of membrane proteins and the release of soluble factors. Here we report that in NK-DC cocultures, among a set of 84 cytokines investigated, activin A was the second highest induced gene, with CXCL8 being the most upregulated one. Activin A is a member of the TGF-M-NM-2 superfamily and was previously shown to possess both pro- and antiinflammatory activities. In NK-DC cocultures, the induction of activin A required cell contact and was dependent on the presence of proinflammatory cytokines (i.e. IFN-M-NM-3, TNF-M-NM-1 and GM-CSF) as well as on NK cell-mediated DC killing. CD1+ DC were the main activin A producer cells among myeloid blood DC subsets. In NK-DC cocultures, inhibition of acitivn A by follistatin, a natural inhibitory protein, or by a specific blocking antibody, resulted in the upregulation of proinflammatory cytokine release (i.e. IL-6, IL-8, TNF-M-NM-1) by DC and in the increase of DC maturation. In conclusion, our study reports that activin A, produced during NK-DC interactions, represents a relevant negative feedback mechanism that might function to prevent excessive immune activation by DC. Human CD14 positive monocytes were differentiated to DC in vitro in the presence of IL-4 (20 ng/ml) and GM-CSF (50 ng/ml) for 6 days. Immature DC were then cocultured with allogeneic IL-15-activated NK cells (at 1:1 NK:DC ratio) for 0, 2 and 6 hrs. RNA was obtained from three independent coculture experiments. Equal amount of total RNA from each experiment was pooled prior to gene expression analysis. The gene expression of common cytokines was quantified using an RT2 Profiler PCR Array (Qiagen).

Project description:Murine BV2 microglia cells were transfected either with siRNA negative control or siRNA against caspase-3 for 48h. Later on some the of the BV2 transfected cells were co-cultured with C6 glioma cells during 6h. We used the SA Biosciences Mouse Wound Healing PCR Array (PAMM-121Z) to quantitate gene expression of relevant genes related to the wound healing process Glioma cells recruit and exploit microglia, resident immune cells of the brain, for their proliferation and invasion capability. The underlying molecular mechanism used by glioma cells to transform microglia into a tumor-supporting phenotype remains elusive. Here, we report that glioma-induced microglia conversion is coupled to a reduction of basal microglial caspase-3 activity, increased S-nitrosylation of mitochondria-associated caspase-3 through inhibition of thioredoxin-2 activity, and demonstrate that caspase-3 inhibition regulates microglial tumor-supporting function. Further, we identified nitric oxide synthase-2 (NOS2) activity originating from the glioma cells as a driving stimulus in the control of microglial caspase-3 activity. Repression of glioma NOS2 expression in vivo led to reduction in both microglia recruitment and tumor expansion, whereas depletion of the microglial caspase-3 gene promoted tumor growth. This study provides evidence that the inhibition of Trx2-mediated denitrosylation of SNO-procaspase-3 is part of the microglial pro-tumoral activation pathway initiated by glioma cancer cells. qPCR gene expression profiling. Three independent experiments of siControl BV2 monoculture, siCaspase3 BV2 monoculture, siControl BV2 cocultured 6h with C6 glioma cells and siCaspase3 BV2 cocultured 6h with C6 glioma cells.
