Project description:Gene expression profiling reveals functional difference between Sq and HH-Sq on differentiation, metabolism, and lipid droplot formation of dADSC Microarray gene expression profiling was conducted for technical replicates of adipocyte induced dADSC (IN), adipocyte induced and treated with Sq (Sq), adipocyte induced and treated with HH-Sq (HH-Sq) for 14 days (1 µM) to identify its effect in the regulation of adipocyte differentiation, metabolism, and lipid droplet accumulation. Technical replicates represent the same hybridization mixture applied to 3 independent arrays.

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.

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.

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.

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

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.

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 male Large White x Landrace Large swine animals Method: Study the Hepatic mRNA profile of swine animals in response to a steatotic diet supplied with 0.5% squalene over a month by Transcriptome sequencing using DNBseq platform. Sequence reads that passed quality filters were mapped onto reference genome, followed by SNP & INDEL variants 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 including alternative 5' splicing, alternative 3' splicing , retained intron, skipped exons and 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 18,659 in the squalene group and 18,602 in control group.

Project description:Paracrine Hedgehog (Hh) signaling regulates growth and patterning in many Drosophila organs. We mapped chromatin binding sites for Cubitus interruptus (Ci), the transcription factor that mediates outputs of Hh signal transduction, and we analyzed transcription profiles of control and mutant embryos to identify genes that are regulated by Hh. Putative targets we identified include several Hh pathway components, most previously identified targets, and many targets that are novel. Analysis of expression patterns of pathway components and target genes gave evidence of autocrine Hh signaling in the optic primordium of the embryo. And, every Hh target we analyzed that is not a pathway component appeared to be regulated by Hh in a tissue-specific manner. We present evidence that Hh-dependent tissue specificity is dependent upon transcription factors that are Hh-independent, suggesting that “pre-patterns” of transcription factors partner with Ci to make Hh-dependent gene expression position-specific.

A total of 14 samples were analysed consisting of comparisons of hh-, ci-, smo-, ptc-, and Cim1-m4 (Activator) mis-expression embryos compared to wt sibling embryos.

Project description:Purpose: Most Hedgehog responsive gene expression is mediated through GLI de-repression. Additionally GLI -repression is proposed to play roles in limb pre-patterning before HH pathway activation. This study evaluates if GLI repression is established prior to HH pathway activation. Methods: To determine if GLI-repression is established prior to pathway activation, we used genomic approaches to study GLI-mediated repression using the mouse developing limb as a model. We identified pre-HH (E9.25, 21-23S) and post-HH (E10.5, 32-25S) GLI3 binding regions using CUT&RUN for endogenous FLAG-tagged GLI3 proteins. Using a combination of ChIP-seq, CUT&RUN, CUT&Tag, ATAC-seq and RNA-seq, we tested whether loss of Gli3 prior to HH signaling was able to de-repress genes and enhancers, as it does after HH signaling. Results: Prior to HH signaling, GLI3 binds to poised, accessible regions with histone deacetylase (HDAC) proteins, similar to post-HH signaling. Despite GLI3 binding to most regions as it does in the post-HH limb, loss of Gli3 is unable to prematurely active target genes or enhancers. Furthermore, we find that GLI3-dependent chromatin compaction does not occur until roughly 10 hours after HH signaling would have normally been induced. Collectively, these results support that GLI repressor proteins are inert prior to HH pathway activation.
