Project description:Analysis of gene expression in human retinal pigment epithelium cell line (RPE) infected with influenza A viruses expressing wild type NS1 protein or its mutant R38A, K41A. The hypothesis tested was that R38 and K41 residues within viral NS1 protein are essential fro transctiptional control of cellluar gene expression. Cells were infected with influenza A/WSN/33 viruses expressing wild type NS1 protein (WT), its R38A, K41A mutant (RK/AA) or non-infected (Mock) Total RNA isolated from RPE cells after 10 hours of infection with wild type or mutant influenza A virus (multiplicity of infection = 1)

Project description:The pathogenesis and host viral interactions of the Crimean–Congo hemorrhagic fever virus (CCHFV) are convoluted and have not been evaluated previously. To understand the host immune responses against CCHFV, we have performed a global transcriptomic analysis of peripheral blood mononuclear cells from a longitudinal cohort of CCHF patients who survived, and a temporal untargeted proteomics analysis of CCHFV infected cells. Our results indicate that during the acute phase of CCHFV infection, metabolic reprogramming of the host towards central carbon metabolism including glycolysis/gluconeogenesis occurs. This could potentially be regulated by the PI3K/Akt, HIF-1, FoxO, and AMPK signaling pathways and play a central role in viral replication. Moreover, key interferon stimulating genes (ISGs: ISG12, ISG15, ISG20 and MXs: Mx1 and Mx2) are activated during infection, suggesting a role for type I and II interferon-mediated antiviral mechanisms. Targeting type I interferon response through metabolic rewiring could be an attractive therapeutic intervention for CCHFV.

Project description:Analysis of the cystic fibrosis gene Cftr in the colon and small intestine of Cftr-deficient murine model. The hypothesis was loss of Cftr altered expression of genes important in intestinal homeostasis and oncogenic signaling pathways. The results identified potential roles of Cftr in up- or down-regulating major gene clusters that belong to groups of immune response, ion channel, intestinal stem cell and other growth regulators. Total RNA was isolated from the normal intestine of three Apc wildtype Cftr wildtype and three Apc Cftr-deficient mice. For the colon intestinal epithelia from the same region of the distal colon of each mouse was separated from the rest of the intestine prior to RNA isolation. Therefore RNA was obtained from only epithelial cells. For the small intestine, a section of the mid-duodenum from each mouse was sheared of villi prior to RNA isolation. Therefore RNA was obtained from whole duodenum (minus villi), containing epithelia cells but also stromal and other cells. RNA Seq was then conducted on all samples, with at least two replicates for each biological sample.

Project description:Photodynamic therapy (PDT) of solid cancers comprises the administration of a photosensitizer followed by illumination of the photosensitizerreplete tumor with laser light. This induces a state of local oxidative stress, culminating in the destruction of tumor tissue and microvasculature and induction of an anti-tumor immune response. However, some tumor types, including perihilar cholangiocarcinoma, are relatively refractory to PDT, which may be attributable to the activation of survival pathways in tumor cells following PDT (i.e., activator protein 1 (AP-1)-, nuclear factor of kappa light polypeptide gene enhancer in B-cells (NF-κB)-, hypoxia-inducible factor 1-alpha (HIF-1α)-, nuclear factor (erythroid-derived 2)-like 2 (NFE2L2), and unfolded protein response-mediated pathways). To assess the activation of survival pathways after PDT, human perihilar cholangiocarcinoma (SK-ChA-1) cells were subjected to PDT with zinc phthalocyanine (ZnPC)-encapsulating liposomes. Following a 30-minute incubation with liposomes, the cells were either left untreated or treated at low (50 mW) or high (500 mW) laser power (cumulative light dose of 15 J/cm2). Cells were harvested 90 minutes post-PDT and whole genome expression analysis was performed using Illumina HumanHT-12 v4 expression beadchips. Hilar cholangiocarcinoma (SK-ChA-1) cells were incubated with PBS (control group) or 500 μM zinc phthalocyanine (ZnPC)-encapsulating liposomes (ZnPC-ITLs, final lipid concentration). After 30 minutes, cells that were incubated with ZnPC-ITLs were either kept in the dark (ITL group) or were treated with 500-mW (ITL 500) or 50-mW (ITL 50) laser light (n = 3 per group, cumulative light dose of 15 J/cm2). Ninety minutes after photodynamic therapy, total cellular RNA was isolated and gene expression levels were analyzed by using the Illumina HumanHT-12 v4 platform. The data was analyzed in the context of survival signalling and comparisons were made with the control group.

Project description:Successful development of HIV-vaccination strategies will also depend on the ability to use novel approaches to analyse and integrate immunogenicity data generated in vaccine trials. The ANRS VAC 18 trial evaluated the immunogenicity of HIV-LIPO-5 vaccine (5 HIV peptides coupled to a palmytoil tail) administered at W0, 4, 12 and 24 in healthy volunteers. 62-69% of vaccinees developed HIV-specific ELISpot responses by W26. Here we present extensive immunogenicity assessments in a subset of vaccinees using ELISpot, lymphoproliferation, intracellular cytokine staining (ICS), cytokine multiplex and transcriptomic analyses. Peripheral blood mononuclear cells from volunteers collected before and following vaccinations were stimulated with HIV LIPO 5 vaccine, Gag peptides contained or not in the vaccine as controls. Different time points and stimulation conditions were compared, using false discovery rate to control for test multiplicity. 74% and 30% of vaccinees had cultured ELISpot and lymphoproliferation responses at W14, respectively. Ex-vivo ICS showed mainly single IL-2 producing cells. Secretion of IFN-γ, TNF-α, IL-5, and IL-13 increased significantly in response to Gag stimulation after culture at W14 compared to W0. An induction of metallothionein genes was consistently detected after HIV-LIPO-5 stimulation at W0 and W14 related to the adjuvant effect of the lipid tail. After vaccination (W14), significant probes increased substantially (>1200 probes) including IFN-γ, CXCL9, IL2RA, TNFAIP6, CCL3L1 and IL-6 W14 (fold change > 100%). In conclusion, HIV LIPO-5 vaccination elicited memory precursor responses with a Th1 and Th2 profile. The signature profile before vaccination provides information about the adjuvant effect of the lipid tail. Consistently with cytokine responses, vaccination is associated with a modulation in gene expression. This combined approach allowed to identify new signatures of HIV vaccine response and indicates that HIV-LIPO-5 could be further developed as a prime component of heterologous prime boost strategies. PBMC mRNA of 12 healthy volunteers, stimulate in four different conditions (HIV-LIPO-5, Gag+, Gag-, NS) during 6 and 24 hours before and after vaccination (week 0 and week 14)

Project description:Analysis of serum starved prelamin A-accumulating hMSCs at gene expression level. The hypothesis tested in the present study was that prelamin A accumulation induces the dysregulation of genes that are essensial for cell survival under a stress condition such as serum starvation. The results provide important information about these genes and the functional categories that are dysregulated due to prelamin A accumulation in serum starved hMSCs. Two samples are analyzed in this microarray experiment: human mesenchymal stem cell cultured under serum starvation conditions (during 24 hours) which accumulate prelamin A (pre-hMSCs) and control mesenchymal stem cells (ctrl-hMSCs). 2 biological replicates (hMSCs derived from 2 different bone marrow donors) and 1 technical replicate are included in this analysis.
