Lipin-1 deficiency is associated with massive rhabdomyolysis episodes in humans, precipitated by febrile illnesses. Despite well-known roles of lipin-1 in lipid biosynthesis and transcriptional regulation, the pathogenic mechanisms leading to rhabdomyolysis remain unknown. Here we show that primary myoblasts from lipin-1-deficient patients exhibit a dramatic decrease in LPIN1 expression and phosphatidic acid phosphatase 1 activity, and a significant accumulation of lipid droplets (LD). The expre ...[more]

Cytokine interactome alterations promote oropharyngeal Epstien-barr virus (EBV) replication and shedding during HIV infection

Project description:Proteomic analysis of cytokines in unstimulated oropharyngeal secretions. Epstein-barr virus (EBV) is a type 1 carcinogen which causes many cancers in humans. Here we explored the cytokine involvement of the EBV replication process in the oropharynx. Cytokine interactomic profiles were geneerated to understand the involved signalling pathways in HIV infected group and the healthy group. Proteome profilers were used to understand the major cytokine expression levels that are related to infection and immune regulation. We analyzed unstimulated oropharyngeal samples (UOPS) from 42 healthy subjects and 72 HIV positive subjects using the R & D Proteome Profiler array panels. No techinical replicates were performed. 14 samples in HIV group without therapy (NHAART group); 58 HIV patients with highly active antiretroviral therapy (HAART group); 42 samples in healthy group

DUX4-induced gene expression is the major molecular signature in FSHD skeletal muscle

Project description:Facioscapulohumeral dystrophy (FSHD) is caused by decreased epigenetic repression of the D4Z4 macrosatellite array and recent studies have shown that this results in the expression of low levels of the DUX4 mRNA in skeletal muscle. Several other mechanisms have been suggested for FSHD pathophysiology and it remains unknown whether DUX4 expression can account for most of the molecular changes seen in FSHD. Since DUX4 is a transcription factor, we used RNA-seq to measure gene expression in muscle cells transduced with DUX4, and in muscle cells and biopsies from control and FSHD individuals. We show that DUX4 target gene expression is the major molecular signature in FSHD muscle together with a gene expression signature consistent with an immune cell infiltration. In addition, one unaffected individual without a known FSHD-causing mutation showed expression of DUX4 target genes. This individual has a sibling with FSHD and also without a known FSHD-causing mutation, suggesting the presence of yet unidentified modifier locus for DUX4 expression and FSHD. These findings demonstrate that expression of DUX4 accounts for the majority of the gene expression changes in FSHD skeletal muscle together with an immune cell infiltration. RNA-seq for muscle cells and biopsies from control and FSHD individuals.

Food-associated Lactiplantibacillus plantarum C9O4 reverts inflammation and apoptosis in intestinal epithelial cells: a proteomic insight

Project description:Nowadays, Western diets and lifestyle lead to an increasing occurrence of chronic gut inflammation, that represents an emerging health concern with still a lack of successful therapies. Fermented foods, and their associated Lactic Acid Bacteria, have recently regained popularity for their probiotic potential including the maintenance of gut homeostasis by modulating the immune and inflammatory response. Our study aims to investigate the cross-talk between the food-borne strain Lactiplantibacillus plantarum C9O4 and intestinal epithelial cells in an in vitro inflammation model. Cytokines profile shows the ability of C9O4 to significantly reduce levels of IL-2, IL-5, IL-6, and IFN-γ. Proteomic functional analysis reveals an active host-microbe interaction that highlights an immunoregulatory role of C9O4, able to revert both the detrimental effects of IFN-γ through the JAK/STAT pathway and the apoptosis process in inflamed cells. These results suggest a promising therapeutic role of fermented food-associated microbes for the management of gastrointestinal inflammatory diseases.

Gene expression profiling of HUVEC after stimulation with an inflammatory mediator cocktail

Project description:To understand the transcripts regulated by inflammation and how this regulation may differ between different individuals, the transcriptome of HUVECs stimulated with inflammatory mediators was examined in 9 different individuals. In the study present here, HUVEC isolates from 9 different individuals were cultured until passage 4 in fully supplemented growth conditions. Passage 4 HUVEC isolates were then treated with a cocktail of inflammatory mediators (10ng/ml TNF-α, Il-1β, Il-8) for a period of 24 hours prior to RNA extraction. RNA was extracted and hybridised onto CodeLink microarrays. The expression profiles in the inflammatory mediator treated condition were examined along side a superset of the same biological replicates that were untreated (also submitted), to facilitate assessment of the resting transcriptome.

Engineering of human myotubes towards a mature metabolic and contractile phenotype

Project description:Skeletal muscle mediates the beneficial effects of exercise, thereby improving insulin sensitivity and reducing the risk for type 2 diabetes. Current skeletal-muscle-models in vitro are incapable of fully recapitulating its physiological functions especially regarding exercise. Supplementation of IGF1, a growth factor secreted by myofibers in vivo, might help to overcome these limitations. Primary human CD56-positive myoblasts were differentiated into myotubes in the presence/absence of IGF1 in serum-free medium for 10 days. Daily collected samples were analyzed by proteomics, qRT-PCR and myotube contractibility via electrical-pulse-stimulation (EPS). Mitochondrial respiration and glucose uptake were measured. IGF1-supported differentiation formed thicker multinucleated myotubes showing physiological contraction upon EPS following day 6 while myotubes without IGF1 were almost incapable of contraction. IGF1-treatment upregulated particularly muscle-specific proteins that contribute to myofibril and sarcomere assembly, striated muscle contraction, and ATP production. Elevated PPARGC1A, MYH7 and reduced MYH1/2 suggest a switch towards a more oxidative phenotype in line with elevated mitochondrial respiration. IGF1-treatment also upregulated expression of GLUT4 and increased insulin-dependent glucose uptake. To conclude, utilizing IGF1, we engineered human myotubes that recapitulate the physiological traits of skeletal muscle in vivo vastly superior to established protocols. This novel model enables investigation of exercise on a molecular level, drug screening and interorgan-crosstalk by transfer to organ-on-chip.
