  1. A role for CPT1A to prevent blood vessel permeability revealed by in depth proteomics OmicsDI

    ID: PXD001186

    Date Released: 01-28-2015

    Description: embled into a fully formed network. Inhibition of CPT1A in ECs, a limiting enzyme in FAO, results in disruption of this network. Acute CPT1A inhibition reduces cellular ATP levels and oxygen consumption, which can be restored replenishing the tricarboxylic acid cycle (TCAc). Phosphoproteomic changes upon acute CPT1A inhibition evoked those triggered by thrombin, a potent inducer of EC permeability through calcium signaling. Indeed, CPT1A inhibition increased EC permeability and vascu...

    ID: E-GEOD-35862

    Description: expression of carnitine palmitoyltransferase 1A (CPT1A) decreased. We showed that PAX3-FKHR binds directly and specifically to a paired-domain binding-site in the CPT1A promoter region, indicating that CPT1A is a novel direct transcriptional target of PAX3-FKHR. Furthermore, downregulating CPT1Adecreased cell motility in ARMS cells, indicating that CPT1A is a downstream effector of PAX3-FKHR-mediated cell migration and metastasis. Conclusions: Taken together, we have identified CPT1A as a novel direct transcriptional target of PAX3-FKHR and revealed the novel function of CPT1A in promoting cell motility. CPT1A may represent a novel therapeutic target for the treatment of ARMS. Identification of transcription targets of PAX3-FKHR in human alveolar rhabdomyosarcoma: By stably knocking down PAX3-FKHR in human alveolar rhabdomyosarcoma cell line Rh30 and comparing the gene expression profile of the knockdown clone (KD) to the parental Rh30, transcription targets of PAX3-FKHR have been identified. Gene expression in parental Rh30 cells was compared to that in either Rh30 cells stably expressing shRNA targeting PAX3-FKHR (KD) or control non-targeting shRNA (CON), in duplicate....

  11. Blood gene expression reveals reduced circadian rhythmicity in individuals resistant to sleep deprivation ArrayExpress

    ID: E-GEOD-56931

    Description: ting for circadian effects, two genes (SREBF1 and CPT1A, both involved in lipid metabolism) exhibited small, but significant, linear changes in expression with the duration of SD (FDR<5%). The main change with SD was a reduction in the amplitude of the diurnal rhythm of expression of normally cycling probe sets. This reduction was noticeably higher in behaviourally resistant subjects than sensitive subjects, at any given p-value. Furthermore, blood cell type enrichment analysis showed that the expression pattern difference between sensitive and resistant subjects is mainly found in cells of myeloid origin, such as monocytes. Individual differences in behavioural effects of sleep deprivation are associated with differences in diurnal amplitude of gene expression for genes that show circadian rhythmicity. Blood draws were done every 4 hours during a 3-day (+1 baseline day) study: 24-hour normal baseline (6 time points: day 1 8hr, 12hr, 16hr, 20hr, day 2 0hr, 4hr), 38 hours of continuous ...

    Access Type: download

    dataset.description: transcripts, including ANGPTL4, PDK4, PLIN2, and CPT1A. The increase in both PDK4 and ANGPTL4 RNA expression was abolished in the presence of either PPARδ antagonist GSK0660 or GSK3787. The induction of PDK4 by LPCs was blocked with siRNA against PPARD. The activation of PPARδ transcriptional activity by LPC was shown as PPARδ-dependent luciferase reporter gene expression and enhanced DNA binding of the PPARδ/RXR dimer. On a functional level, further results show that the LPC-mediated activation of PPARδ can reduce fatty acid-induced inflammation and ER stress in human skeletal muscle cells. The protective effect of LPC was prevented in the presence of the PPARδ antagonist GSK0660. Taking together...

    ID: E-GEOD-17254

    Description: many represented known PPARα targets, including CPT1A, HMGCS2, FABP, ACSL, and ADFP. Several genes were identified that were specifically induced by PPARα in human (MBL2, ALAS1, CYP1A1, TSKU) or mouse (Fbp2, lgals4, Cd36, Ucp2, Pxmp4). Furthermore, several putative novel PPARα targets were identified that were commonly regulated in both species, including CREB3L3, KLF10, KLF11 and MAP3K8. Our results suggest that PPARα activation has a major impact on gene regulation in human hepatocytes. Importantly, the role of PPARα as master regulator of hepatic lipid metabolism is generally well-conserved between mouse and human. Overall, however, PPARα regulates a mostly divergent set of genes in mouse and human hepatocytes.

  19. The impact of PPARα activation on whole genome gene expression in human precision-cut liver slices ArrayExpress

    ID: E-GEOD-71731

    Description: e classical PPARα targets PLIN2, VLDLR, ANGPTL4, CPT1A and PDK4 are robustly induced by PPARα activation. Transcriptomics analysis indicated that 617 genes were upregulated and 665 genes were downregulated by PPARα activation (q value<0.05). Many genes induced by PPARα activation were involved in lipid metabolism (ACSL5, AGPAT9, FADS1, SLC27A4), xenobiotic metabolism (POR, ABCC2, CYP3A5) or the unfolded protein response, whereas most of the downregulated genes were involved in immune-related pathways. Among the most highly repressed genes upon PPARα activation were several chemokines (e.g. CXCL9-11, CCL8, CX3CL1, CXCL6), interferon γ-induced genes (e.g. IFITM1, IFIT1, IFIT2, IFIT3) and numerous other immu...

Many genes induced by PPARα activation were involved in lipid metabolism (ACSL5, AGPAT9, FADS1, SLC27A4), xenobiotic metabolism (POR, ABCC2, CYP3A5) or the unfolded protein response, whereas most of the downregulated genes were involved in immune-related pathways. Among the most highly repressed genes upon PPARα activation were several chemokines (e.g. CXCL9-11, CCL8, CX3CL1, CXCL6), interferon γ-induced genes (e.g. IFITM1, IFIT1, IFIT2, IFIT3) and numerous other immu...

  39. Blood gene expression reveals reduced circadian rhythmicity in individuals resistant to sleep deprivation OmicsDI

    ID: E-GEOD-56931

    Date Released: 10-03-2014

    Description: ting for circadian effects, two genes (SREBF1 and CPT1A, both involved in lipid metabolism) exhibited small, but significant, linear changes in expression with the duration of SD (FDR<5%). The main change with SD was a reduction in the amplitude of the diurnal rhythm of expression of normally cycling probe sets. This reduction was noticeably higher in behaviourally resistant subjects than sensitive subjects, at any given p-value. Furthermore, blood cell type enrichment analysis showed that the expression pattern difference between sensitive and resistant subjects is mainly found in cells of myeloid origin, such as monocytes. Individual differences in behavioural effects of sleep deprivation are associated with differences in diurnal amplitude of gene expression for genes that show circadian rhythmicity. Blood draws were done every 4 hours during a 3-day (+1 baseline day) study: 24-hour normal baseline (6 time points: day 1 8hr, 12hr, 16hr, 20hr, day 2 0hr, 4hr), 38 hours of continuous ...

    Description: g PEPCK, FBP1, IRS1, IRS2, AKT2 ADIPOR1, PDK4 and CPT1A. Our findings suggest a novel mechanism for the regulation of HGP by TCF7L2, and provide a possible explanation for the association of TCF7L2 polymorphisms with the incidence of T2DM. two samples: TCF7L2 ChIP-Seq and Input DNA...

  41. Transcription profiling by array of human primary hepatocytes after treatment with pirinixic acid OmicsDI

    ID: E-GEOD-17251

    Date Released: 07-28-2015

    Description: ny represented known PPARalpha targets, including CPT1A, HMGCS2, FABP, ACSL, and ADFP. Several genes were identified that were specifically induced by PPARalpha in human (MBL2, ALAS1, CYP1A1, TSKU) or mouse (Fbp2, lgals4, Cd36, Ucp2, Pxmp4). Furthermore, several putative novel PPARalpha targets were identified that were commonly regulated in both species, including CREB3L3, KLF10, KLF11 and MAP3K8. Our results suggest that PPARalpha activation has a major impact on gene regulation in human hepatocytes. Importantly, the role of PPARalpha as master regulator of hepatic lipid metabolism is generally well-conserved between mouse and human. Overall, however, PPARalpha regulates a mostly divergent set of genes in mouse and human hepatocytes. Experiment Overall Design: Primary hepatocytes from 6 human subjects were treated with the PPARalpha agonist Wy14643 for 6 and 24 hours, and gene expression profiling was performed using Affymetrix GeneChips. Human hepatocytes and Hepatocyte Culture Medium Bulletkit were purchased from Lonza Bioscience (Verviers, Belgium). Primary hepatocytes were isolated from surgical liver biopsies obtained from six individual donors who underwent surgery after informed consent was obtained for surgery with subsequent use of samples in experiments. Hepatocytes were isolated with two-step collagenase perfusion method and th...

Overall, however, PPARα regulates a mostly divergent set of genes in mouse and human hepatocytes. Experiment Overall Design: Primary hepatocytes from 6 mice from 6 different strains were treated with the PPARα agonist Wy14643 for 6 and 24 hours, and gene expression profiling was performed using Affymetrix GeneChips. Mouse primary hepatocytes were isolated by two-step collagenase perfusion from 6 different strains of mouse; NMRI, SV129, FVB, DBA, BALB/C and C57BL/6J. Cells were plated on collagen-coated six-well plates. Viability was determined by Trypan Blue exclusion, and was at least 75%. Hepatocytes were suspended in William's E medium (Lonza Bioscience, Verviers, Belgium) supplemented with 10...
