Project description:Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic diseases globally and nonalcoholic steatohepatitis is its progressive stage with limited therapeutic options. Here a role for intestinal peroxisome proliferator-activated receptor α (PPARα)-fatty acid binding protein 1 (FABP1) in obesity-associated metabolic syndrome, fatty liver and nonalcoholic steatohepatitis via modulating dietary fat absorption was uncovered. Intestinal PPARα is highly activated accompanied by marked upregulation of FABP1 by high-fat diet (HFD) in mice and obese humans. Intestine-specific PPARα or FABP1 disruption in mice decreases HFD-induced obesity, fatty liver and nonalcoholic steatohepatitis and intestinal PPARα disruption fails to further decrease obesity and NASH. Chemical PPARα antagonism improves metabolic disorders depending on the presence of intestinal PPARα or FABP1. Translationally, GW6471 decreases human PPARα-driven intestinal fatty acid uptake and therapeutically improves obesity in PPARA-humanized, but not Ppara-null, mice. These results suggest that intestinal PPARα-FABP1 axis could be a therapeutic target for NASH.

Project description:Chlorogenic acid (CGA) is a crucial bioactive dietary polyphenol found in plants and serves as the primary ingredient in numerous traditional Chinese medicine preparations. Due to its beneficial impact on treating metabolic syndrome, it has garnered significant attention in medical research. Previous studies have demonstrated that chlorogenic acid possesses antioxidative, antibacterial, antiviral, anti-tumor, lipid-lowering, glucose-lowering, and immunomodulatory properties, indicating its potential role in regulating metabolism. Human embryonic stem cells (hESCs) exhibit self-renewal and multi-directional differentiation capabilities. Any element within the culture system can alter the microenvironment and influence hESC metabolism. Therefore, hESCs provide a valuable and high-throughput model for investigating CGA's regulatory mechanism on metabolism in vitro. While previous studies have explored CGA's important regulatory role in human metabolism, its specific impact on hESCs metabolism remains undisclosed. Metabolites of hESCs are critical targets for enhancing stem cell function regulation. Prior research has emphasized the essential nature of de novo synthesis and β-oxidation of fatty acids for regulating hESCs; however, CGA's roles and mechanisms in regulating fatty acid metabolism within hESCs remain unelucidated. This study utilizes transcriptome analysis combined with epigenetics to investigate CGA's regulation of fatty acid metabolism within hESCs while analyzing the molecular mechanisms involved—providing a theoretical foundation for future regulation of HESC metabolism by CGA and offering potential optimizations for hESCs culture systems.
Project description:In this study, we performed de novo transcriptome assembly for L. japonica, representing transcripts from nine different tissues. A total of 22Gbps clean RNA-seq reads from nine tissues of L. japonica were used, resulting in 243,185 unigenes, with 99,938 unigenes annotated based on homology search using blastx against NCBI-nr protein database. Unsupervised principal component analysis and correlation studies using transcripts expression data from all nine tissues of L. japonica showed relationships between tissues explaining their association at different developmental stages. Homologs for all genes associated with chlorogenic acid, luteolin, and secoiridoid biosynthesis pathways were identified in the L. japonica transcriptome assembly. Expression of unigenes associated with chlorogenic acid were enriched in stem and leaf-2, unigenes from luteolin were enriched in stem and flowers, while unigenes from secoiridoid metabolic pathways were enriched in leaf-1 and shoot apex. Our results showed that different tissues of L. japonica are enriched with sets of unigenes associated with a specific pharmaceutically important metabolic pathways, and therefore, possess unique medicinal properties. Present study will serve as a resource for future attempts for functional characterization of enzyme coding genes within key metabolic processes.
