Hep3B time-course

ABSTRACT: A time-course (T0, 15, 30 min, 1, 3, 6 or 16 hours) of mRNA abundance changes was studied in the human Hep3B hepatoma cell line challenged with a pro-inflammatory cytokine-enriched medium (CM,conditionned medium) vs control medium (NCM,non conditionned medium). Paired cultures prepared from a same batch of trypsinized cells were challenged with CM vs NCM for a given length of time and this was repeated in three independent experiments (S1,S2,S3). Keywords: time-course

Predominance of interferon-related responses in the brain during murine malaria as identified by microarray analysis.

Project description:Cerebral malaria (CM) can be a fatal manifestation of Plasmodium falciparum infection. We examined global gene expression patterns by microarray during fatal murine CM (FMCM) and non-cerebral malaria (NCM). There was differential expression of a number of genes, including some not yet characterized in the pathogenesis of FMCM. Some gene induction was observed during Plasmodium infection regardless of the development of CM and there was a predominance of genes linked to IFN responses, even in NCM. However, upon real-time PCR validation and quantitation, these genes were much more highly expressed in FMCM than in NCM. The observed changes included genes belonging to pathways such as interferon (IFN) signaling, MHC processing and presentation, apoptosis, immunomodulatory and anti-microbial processes. We further characterized differentially expressed genes by examining the cellular source of their expression as well as their temporal expression patterns during the course of malaria infection. These data identify a number of novel genes that represent interesting candidates for further investigation in FMCM. Keywords: disease state analysis

Differential gene expression in Hep3B and Hep3B SOX4-/- cells

Project description:Overexpression of SOX4 in various kinds of cancers specimen was associated with poor prognosis of patients; however, the role of SOX4 in angiogenesis or tumor microenvironment modulation remains unclear. Therefore the endogenous SOX4 was knockout and the differential gene expression between Hep3B and Hep3B SOX4-/- cells were examined via genechip. We found that the differentially expressed genes, EzH2, a SOX4-associated partner, and CXCL12, were repressed in Hep3B SOX4-/- cells compared with parental Hep3B; these results were further assessed via qRT-PCR in Hep3B SOX4-/- versus Hep3B cells.

Transcriptional profile comparing Hep3B transfected with miR-19b inhibitor with Hep3B transfected with control

Project description:miR-19b was up-regulated with hepatocellular carcinoma. We compared the transcriptional profile of Hep 3B transfected with miR-19b inhibitor with Hep3B transfected with control to identify genes affected by miR-19b knockdown. Hep 3B_miR-19b transfected vs Hep 3B_control transfected

Donor non-classical monocytes recruit recipient classical monocytes from the spleen by activating donor alveolar macrophages

Project description:Primary Graft Dysfunction (PGD) is the predominant cause of early graft loss following lung transplantation. We recently demonstrated that donor pulmonary intravascular non-classical monocytes (NCM) initiate neutrophil recruitment. Simultaneously, host-origin classical monocytes (CM) are mobilized from the spleen and, upon entry into the allograft, permeabilize the vascular endothelium to allow neutrophil extravasation necessary for PGD. Here, we show that CCL2-CCR2 axis is necessary for CM recruitment. Surprisingly, although intravital imaging and multichannel flow cytometry revealed that pharmacological or genetic depletion of donor NCM abrogated CM recruitment, single-cell RNAseq identified donor alveolar macrophages (AM) as predominant CCL2 secretors. Unbiased transcriptomic analysis of human and murine tissues combined with murine knockouts and chimeras indicated that while IL1β was secreted by multiple cell lineages, donor NCM were responsible for the early activation of AM and CCL2 release. IL1β production by NCM was NLRP3 inflammasome-dependent and inhibited by donor treatment using a clinically approved sulphonylurea, Glyburide. Production of CCL2 in the donor AM occurred through IL1R-dependent activation of PKC and NFκB-pathway. Accordingly, we show that IL1β-dependent paracrine interaction between donor NCM and AM leads to recruitment of host AM necessary for PGD. Since depletion of donor NCM, IL1β or IL1R antagonism, and inflammasome inhibition, abrogated recruitment of CM as well as PGD and are feasible using FDA-approved compounds, our findings have potential for immediate clinical translation.

Splicing of polyA transcripts in Hep3B cells

Project description:We were interested in identifying novel splice junctions in Hep3B cells, especially in genes involved in cholesterol metabolism like HMGCR, so we sequenced polyA-tailed RNA from Hep3B cells. 1 polyA-selected RNA sample was sequenced from Hep3B cells

Murine GMP- and MDP-derived classical monocytes have distinct functions and fates [dataset 2]

Project description:Monocytes are short-lived myeloid immune cells that arise from adult hematopoiesis and circulate for a short time in the blood. They comprise two main subsets, in mice defined as classical Ly6Chigh and non-classical Ly6Clow monocytes (CM, NCM). Recent fate mapping and transcriptomic analyses revealed that CM themselves are heterogeneous. Here, we report surface markers that allow segregation of murine GMP- and MDP-derived CM in the BM and blood. Functional characterization, including fate definition following adoptive cell transfer, established that GMP-Mo and MDP-Mo could equal rise to homeostatic CM progeny, such as NCM in blood and gut macrophages, but differentially seeded selected other tissues. Specifically, GMP-Mo and MDP-Mo gave rise to distinct interstitial lung macrophages, thus linking CM dichotomy to previously reported pulmonary macrophage heterogeneity. Collectively, we provide comprehensive evidence for the existence of two functionally distinct CM subsets in the mouse, which differentially contribute to peripheral tissue macrophage populations in homeostasis and following challenge. Our findings are indicative of impact of monocyte ontogeny on in situ differentiation.
