ABSTRACT: This model represents the non-competitive binding of XIAP to Casapase-3 and Caspase-9. In other words, XIAP mediated feedback is abolished in this model. The authors state that this leads to bistable-reversible behaviour as depicted in Fig 4C. The wild-type model displays a bistable-irreversible profile. This shows that irreversibility requires XIAP mediated feedback. The model was tested on MathSBML.

The intrinsic, or mitochondrial, pathway of caspase activation is essential for apoptosis induction by various stimuli including cytotoxic stress. It depends on the cellular context, whether cytochrome c released from mitochondria induces caspase activation gradually or in an all-or-none fashion, and whether caspase activation irreversibly commits cells to apoptosis. By analyzing a quantitative kinetic model, we show that inhibition of caspase-3 (Casp3) and Casp9 by inhibitors of apoptosis (IAPs ...[more]

Project description:Experimental design Using Circular chromosome conformation capture (4C) assay to uncovers epigenetically regulated intra- and inter-chromosomal interaction network To examine restrictions imposed by the nuclear structure on such cis/trans-chromosomal networks, we developed a high-throughput screening assay 4C and identified 114 different sequences from all autosomes in mouse liver cells. To check the relative frequencies of interactions, the 114 sequences were PCR amplified and spotted on glass to make dedicated microarray. The microarray and 3C validation showed that most of the sequences interact with primarily the maternally inherited H19 imprinting control region (ICR). The epigenetic feature of these interactions was highlighted by the observation that 19% of 4C library sequences are derived from 11 different imprinted domains. In some of these instances, differentially methylated regions (DMRs) interact both in cis and in trans. Moreover, the patterns of chromosomal interactions undergo reprogramming during in vitro maturation of embryonic stem cells. We propose that the nuclear organization of mammalian cells displays considerable plasticity to potentially throw new light on development, cancer epigenetics and evolution of imprinting. Key words: Chromosome conformation capture, CTCF, ICR(Imprinting Control Region) Experimental factors: Genetic variation Experimental design: The 4C samples from both neonatal liver cell SD7 x 142* and 142* x SD7; differentiated embryonic cells and undifferentiated embryonic cells were amplified, fluorescently labeled, and hybridized to 4C dedicated microarray. Quality control steps taken: using pooled samples and gDNA as input, about half of most frequently interactions were confirmed by replicates and dyes swaps.

Project description:A synthetic analog of sphingosine named FTY720 (Fingolimod), phosphorylated by sphingosine kinase-2, interacts with sphingosine-1-phosphate (S1P) receptors expressed on various cells. FTY720 suppresses the disease activity of multiple sclerosis (MS) chiefly by inhibiting S1P-dependent egress of autoreactive T lymphocytes from secondary lymphoid organs, and possibly by exerting anti-inflammmatory and neuroprotective effects directly on brain cells. However, at present, biological effects of FTY720 on human microglia are largely unknown. We studied FTY720-mediated apoptosis of a human microglia cell line HMO6. The exposure of HMO6 cells to non-phosphorylated FTY720 (FTY720-non-P) induced apoptosis in a dose-dependent manner with IC50 of 10.6±2.0 microM, accompanied by the cleavage of caspase-7 and caspase-3 but not of caspase-9. The apoptosis was inhibited by Z-DQMD-FMK, a caspase-3 inhibitor, but not by Pertussis toxin, a Gi protein inhibitor, suramin, a S1P3/S1P5 inhibitor, or W123, a S1P1 competitive antagonist, although HMO6 expressed S1P1, S1P2, and S1P3. Furthermore, both phosphorylated FTY720 (FTY720-P) and SEW2871, a S1P1 selective agonist did not induce apoptosis of HMO6. Genome-wide gene expression profiling and molecular network analysis indicated activation of transcriptional regulation by sterol regulatory element-binding protein (SREBP) in FTY720-non-P-treated HMO6 cells. Western blot verified activation of SREBP2 in these cells, and apoptosis was enhanced by pretreatment with simvastatin, an activator of SREBP2, and by overexpression of the N-terminal fragment of SREBP2. These observations suggest that FTY720-non-P-induced apoptosis of HMO6 human microglia is independent of S1P receptor binding, and positively regulated by the SREBP2-dependent proapoptotic signaling pathway. The HMO6 cell line was established by immortalizing cultured microglia isolated from human embryonic telencephalon tissues with a retroviral vector PASK1.2 encoding v-myc oncogene (Nagai et al. Neurobiol. Dis. 8: 1057-1068, 2001). HMO6 cells express the markers of the microglia/macrophage lineage cells, including CD11b, CD68, CD86, HLA-ABC, HLA-DR, and ricinus communis agglutinin lectin-1 (RCA), serving as a model of human microglia both in vitro and in vivo. The cells were exposed for 2 hours to 10 microM FTY720-non-P dissolved in dimethyl sulfoxide (DMSO) or ethanol or exposed to the vehicle.
