Bulk RNA of IL-4 and squalene treated MDM

Project description:We performed bulk RNA-seq on squalene/M-CSF-treated macrophages to compute the fold change of genes in the squalene/M-CSF compared to M-CSF alone treated macrophages. We then looked at the distribution of the log fold changes in the skin-derived TREM2 (607 genes) and M2-like (709 genes) macrophage scRNA-seq signatures. We found that the TREM2 gene signature was more highly induced by squalene/M-CSF than the M2-like macrophage signature. In these squalene-induced macrophages, we found upregulation of several of the lipid metabolism and pro-inflammatory genes present in the skin-derived TREM2 macrophage gene signature.

Hepatic transcriptomics of squalene in male Apoe-deficient mice on Western diet

Project description:Background and Purpose: Squalene is the main hydrocarbon present in extra virgin olive oil and it has been reported to have anti-steatotic properties in different animal models. The aims of this study were to investigate its effects on liver transcriptomics in Male C57BL/6J Apoe-deficient mice. Experimental Approaches: Male C57BL/6J Apoe-deficient mice were fed a purified Western diet with or without squalene during 11 weeks and hepatic squalene content was assessed. Hepatic transcriptomic changes were studied and confirmed by RT-qPCR. Key Results: Squalene supplementation increased its hepatic content. The Cyp2b10 and Cyp2c55 gene expressions were significantly up-regulated by the squalene intake in all animal models, with independence of sex, sexual hormones, dietary fat content, genetic background and dose, and were strongly associated with antioxidant defense capacity and with lipid content and composition. Conclusions and Implications: hepatic squalene exerts its activity through overexpression of these cytochromes and their changes in virgin olive oil diets may be due to squalene.

MDM from COPD patients and healthy subjects after treatment with LPS or fine and ultrafine particles

Project description:In this study gene expression of monocyte-derived macrophages (MDM) from chronic obstructive pulmonary disease (COPD) patients and healthy subjects was investigated. MDM were treated with LPS, a combination of fine TiO2 and ultrafine Printex90 particles, or remained untreated. Keywords: disease state analysis

A single cell atlas of frozen shoulder capsule identifies features associated with inflammatory fibrosis resolution (Bulk RNA-seq of capsular fibroblasts co-cultured with MDMs)

Project description:Bulk transcriptomic data of shoulder capsule fibroblasts isolated from frozen shoulder co-cultured with Dexamethasone (DEX) or LPS treated monocyte-derived macrophages (MDM), which were isolated from blood cones and stimulated with M-CSF, for 72 hours. The stimulated MDMs have been characterised as MerTKhigh(DEX) and MerTKlow(LPS). Unstimulated, DEX and LPS stimulated MDM were co-cultured with ex vivo shoulder capsule-derived fibroblasts from patients with frozen shoulder. Fibroblasts were then FACS isolated and RNA-sequencing analysis performed. As an additional control ex vivo fibroblasts were also profiled without co-culture (stimulation=”none”).

Effect of squalene on liver transcriptome of mice lacking apolipoprotein E

Project description:The hypothesis that the squalene of olive oil might influence hepatic gene expression in an apoE and sex-dependent ways was tested in mice. Gene expression was analyzed using DNA microarrays in male apoE-deficient mice that received 1 g/kg/day of squalene for 10 weeks. As initial screening of potential candidate genes involved in a differential response, only genes with remarkably modified expression (signal log2 ratio > 1.5 or < -1.5) were further considered

RNA-seq of Staphylococcus aureus and Staphylococcus aureus challenged with squalene compared to control growth

Project description:Squalene makes up 12 % of human skin surface lipids, however little is known about its affects on the host skin microbiome. Here we tested the effect of squalene on genetic regulation of staphylococci, showing that it profoundly affects expression virulence or colonisation determinants, and of iron uptake systems.

Next Generation Sequencing For Quantitative Analysis Of Hepatic Transcriptomes In Response To Squalene

Project description:Purpose: The goal of this study was to determine squalene effect on hepatic transcriptome by comparing high-throughput data for tested group vs. control group in Wildtype New Zealand white rabbits. Method: Hepatic mRNA profile of two Wildtype New Zealand white rabbits groups fed over 4 weeks with 1% of sunflower oil and the second fed with purified 1% of sunflower oil and 0.5% of squalene was analysed by Transcriptome sequencing using DNBseq platform. Sequence reads that passed quality filters were mapped onto reference genome, followed by SNP & INDEL calling and Gene expression detection. Results: Squalene intake did not significantly influence single nucleotide polymorphisms. When alternative splicing events were tested, squalene administration had significant influence on splicing events, alternative 5' splicing, alternative 3' splicing Site and retained intron while no effect was found on skipped exons or mutually exclusive exons. Splicing patterns led to variety of differentially splicing genes and a variety of different isoforms from one gene. Differentially expressed genes were 18,485 in the squalene group and 18,286 in the control group. Conclusions: This study represents the first analysis of hepatic transcriptome in respond to squalene. Result data confirm that RNA-Sequencing is a sensitive and accurate tool that provides a framework for comparative investigations of known and novel DEGs.

Early response of human monocyte-derived macrophages (MDM) to HIV-1

Project description:Human MDM were exposed to VSVG-pseudotyped HIV-1 NL-AD8 for 8h, 24h, and with HIV-1 + AZT for 24h MDM from 3 healthy blood donors were differentiated for 7 days, exposed or not to HIV-1 +/- AZT for 8h and 24h before being lysed. RNA was extracted, reverse-transcribed, hybridized on 2.1 ST microarrays to analyse the early transcriptomic response of MDM to infection.
