Project description:The TRIB1 locus has been associated with lipid dysfunction. The underlying mechanisms were investigated by examining the transcription landscape in response to TRIB1 suppression in human primary hepatocytes. Primary hepatocytes from 3 distinct donors were exposed for 48 h to an antisense nucleotide targeting TRIB1 or a control nucleotide. The resulting impacts on the transcription profile were assessed using Human Transcriptome 2.0 microarrays (Affymetrix).

Project description:Genome-wide expression profiling has been performed in malignant HepG2 cells and compared to the expression in normal human hepatocytes. 56 ucRNAs, representing 11% of all ucRNAs analyzed, were aberrantly and significantly (p<0.05) expressed in malignant HepG2 cells compared to non-malignant human hepatocytes.

Project description:Objective - The TRIB1 locus has been linked to hepatic triglyceride metabolism in mice and to plasma triglycerides and coronary artery disease (CAD) in humans. The lipid associated SNPs identified by genome-wide association studies (GWAS) are located ~ 30 kb downstream from TRIB1 suggesting complex regulatory effects on genes or pathways relevant to hepatic triglyceride metabolism. The goal of this study was to investigate the functional relationship between common SNPs at the TRIB1 locus and plasma lipid traits. Methods & Results - Characterization of the risk locus reveals that it encompasses a gene, TRIB1 associated locus (TRIBAL) comprised of a well conserved promoter region and an alternatively spliced transcript. Bioinformatic analysis and re-sequencing identified a single nucleotide polymorphism (SNP), rs2001844, within the promoter region that associates with increased plasma triglycerides, reduced HDL-C and CAD risk. Furthermore, we show that rs2001844 is an expression trait locus (eQTL) for TRIB1 expression in blood and alters TRIBAL promoter activity in a reporter assay model. The TRIBAL transcript has features typical of long noncoding RNAs (lncRNA), including poor sequence conservation. Modulation of TRIBAL expression had limited impact on either TRIB1 or lipid regulatory genes mRNA levels in human hepatocyte models. In contrast, TRIB1 knockdown markedly increased TRIBAL expression in HepG2 cells and primary human hepatocytes. Conclusions - These studies demonstrate an interplay between a novel locus,TRIBAL, and TRIB1. TRIBAL is located in the GWAS identified risk locus, responds to altered expression of TRIB1, harbors a risk SNP that is an eQTL for TRIB1 expression and associates with plasma triglyceride concentrations. Transcriptome changes to TRIBAL downregulation (48 h) Huh7 were exposed to non-target or TRIBAL-specific antisense oligonucleotides for 48 h in normal (low glucose DMEM, 10% serum, Pen-Strep)
