Proteomic analysis of the effects of Shenzhu Tiaopi granules on model rats with type 2 diabetes mellitus

ABSTRACT: In total, 5856 proteins were identified via proteomics analysis, 97 of which were significantly differentially expressed in the liver and affected fatty acid metabolism, unsaturated fatty acid biosynthesis, the peroxisome proliferator-activated receptor (PPAR) signalling pathway, pyruvate metabolism, and terpenoid backbone biosynthesis. Screening identified 10 target proteins, including perilipin‐2 (Plin2), Pdk4, farnesyl diphosphate synthase (Fdps) and Fdft1. Among these, the key proteins were Plin2 and Fdps, which were found to be associated with the PPAR signalling pathway and terpenoid backbone biosynthesis via the relationship networks

Sesamin alleviates lipid accumulation induced by oleic acid in HepG2 cells

Project description:Sesamin, a special compound present in sesame and sesame oil, has been reported the role in regulating blood lipids and improving liver function, while the underlying mechanisms remain unclear. This study aims to explore its potential mechanisms in regulating lipid metabolism. HepG2 cells were treated with oleic acid to establish an in vitro high-fat cell model to simulate impaired hepatocytes under lipid metabolism disorders.Differentially expressed genes during the sesame intervention were screened by RNA sequencing (RNA seq) and validated using real-time quantitative PCR and Western blot.The data showed that sesamin significantly upregulated the mRNA levels of genes involved in fatty acid metabolism processes such as ETFB, ACAT2, FADS2, FABP1, ACOT1, and those involved in cholesterol metabolism processes such as FDPS, PCSK9, and DHCR7, and downregulated the mRNA levels of CYP24A1 and GGT5 involved in fatty acid metabolism, as well as MVK involved in cholesterol synthesis. Sesamin significantly down-regulated the protein levels of NOTCH1, CD36, SOX4, and FABP1. In summary, sesamin alleviates lipid accumulation in HepG2 by regulating lipid metabolism, with potential mechanisms involving steroid biosynthesis, unsaturated fatty acid biosynthesis, fat digestion and absorption, fatty acid metabolism, Notch signaling pathway, and PPAR signaling pathway.

Real-time quantitative PCR analysis of fatty acid metabolism genes of liver tissue from wild-type and PPAR? (-/-) mice exposed to 2,4-dinitrotoluene (fatty acid)

Project description:2,4-dinitrotoluene (2,4-DNT), a nitroaromatic used in industrial and explosive manufacturing processes, is known to contaminate artillery ranges, demilitarization areas and munitions manufacturing facilities. Previous transcriptomic and lipidomic studies identified energy metabolism as a principle biochemical process affected by 2,4-DNT where up-stream effects on PPAR? signaling were hypothesized as themolecular initiating event for these effects. Here, the validity of this hypothetical adverse outcome pathway (AOP) was assessed by testing the hypothesis that 2,4-DNT-induced perturbations in PPAR? signaling and resultant downstream deficits in energy metabolism, especially from lipids, would result in organism-level impacts on exercise endurance. PPAR? knock-out (-/-) and wild-type (WT) mice were exposed for 14 days to vehicle or 2,4-DNT at a dose (134 mg/kg/day) that did not exhibit overt systemic toxicity. Mice performed an exercise challenge (forced swim) 1 day after the last dose. 2,4-DNT decreased swim times in WT and PPAR? (-/-) mice, but the effect was significantly less in PPAR? (-/-) mice indicating the critical of PPAR? in mediating 2,4-DNT-induced energy metabolism deficits. 2,4-DNT caused down-regulation of transcripts involved in fatty acid metabolism, gluconeogenesis, triacylglycerol catabolism, and the pentose phosphate pathway, and 2,4-DNT treated wild-type mice had decreased serum trigylcerides and increased serum glucose versus 2,4-DNT treated PPAR? (-/-) mice. Our results support the hypothesis that 2,4-DNT perturbs PPAR? signaling as a molecular initiating event therefore impacting energy metabolism, especially lipid metabolism, producing reduced exercise endurance in mice. RNA was isolated from liver tissue of vehicle or 2,4-DNT treated wild-type or PPAR? (-/-) mice (n=6) and RT-PCR performed to analyze genes involved in fatty acid metabolism

Transcription profiling of lung and liver from low and high dose Perfluorooctanoic Acid exposed fetuses

Project description:Exposure to PFOA during gestation altered the expression of genes related to fatty acid catabolism in both the fetal liver and lung. In the fetal liver, the effects of PFOA were robust and also included genes associated with lipid transport, ketogenesis, glucose metabolism, lipoprotein metabolism, cholesterol biosynthesis, steroid metabolism, bile acid biosynthesis, phospholipid metabolism, retinol metabolism, proteosome activation, and inflammation. These changes are consistent with activation of PPAR alpha. Non-PPAR alpha related changes were suggested as well. Experiment Overall Design: Experiment 1: High Dose: Thirty timed-pregnant CD-1 mice were orally dosed from gestation day 1-17 with either 0, 5, or 10 mg/kg/day PFOA in water. At term, fetal lung and liver were collected, total RNA prepared, and samples pooled from three fetuses per litter. Five biological replicates consisting of individual litter samples were then evaluated for treatment group using Affymetrix mouse 430_2 microarrays. Experiment Overall Design: Experiment 2: Low Dose: Thirty timed-pregnant CD-1 mice were orally dosed from gestation day 1-17 with either 0, 1, or 3 mg/kg/day PFOA in water. At term, fetal lung and liver were collected, total RNA prepared, and samples pooled from three fetuses per litter. Five biological replicates consisting of individual litter samples were then evaluated for treatment group using Affymetrix mouse 430_2 microarrays (note one microarray from the lung + 1mg/kg/day dose group was excluded from the study due to high background). Experiment Overall Design: Please note that each dose experiment had separate concurrent controls.

Tonic type 2 immunity controls autoimmunity in the skin

Project description:The existence of immunoregulatory mechanisms that control autoimmunity in non-lymphoid tissues remains unclear. Through transcriptomic and lipidomic analyses, we found that psoriasis is tightly associated with a significant downregulation of fatty acid metabolism and biosynthesis pathways as well as Th2 signature genes. Among lipids-activated transcription factors, LXR and PPAR were required for fatty acid homeostasis and resistance to psoriasis in mice. STAT6 played a role in the homeostatic expression of LXR and PPARγ in the skin. Additionally, innate lymphoid cells established tonic type 2 immunity in normal skin by producing IL-13 continually. Mice lacking tonic type 2 immunity were more susceptible to psoriatic inflammation in vivo. In human skin, inhibiting tonic type 2 immunity worsened psoriasis-like inflammation and IL-17 production, while activating LXR or PPAR inhibited them. Therefore, tonic type 2 immunity is an essential tissue checkpoint that represses autoimmunity and maintains lipid homeostasis in the skin.

Gene expression data from differentiated 3T3-L1 preadipocytes treated with Palmitic Acid, Stearic Acid, Palmitoleic Acid, or Oleic Acid

Project description:Saturated fatty acids (SFA) are widely thought to induce inflammation in adipose tissue (AT), while monounsaturated fatty acids (MUFA) are purported to have the opposite effect; however, it is unclear if individual SFA and MUFA behave similarly. Our goal was to examine adipocyte transcriptional networks regulated by individual SFA (palmitic acid, PA; stearic acid, SA) and MUFA (palmitoleic acid, PMA; oleic acid, OA). Global gene expression was examined in differentiated preadipocytes treated with either 250 μM PA, SA, PMA, or OA for 48 hrs. Individual fatty acid treatments had significant effects on adipocyte gene expression. Functional analyses revealed that PA induced the TLR signalling pathway, while PMA had the opposite effect. SA and OA had similar effects, with increases in key metabolic pathways including mTOR and PPAR signalling, and a reduction in TLR signalling. Ccl5 was validated as a candidate gene that may mediate the differential inflammatory effects of SFA and MUFA in AT. Individual SFA and MUFA trigger distinct transcriptional responses in differentiated preadipocytes, with inflammatory and metabolic pathways particularly sensitive to these fatty acids.

Nordihydroguaiaretic Acid Improves Metabolic Dysregulation and Aberrant Hepatic Lipid Metabolism in Mice by Both PPAR-alpha-Dependent and -Independent Pathways

Project description:To test whether NDGA attenuate dyslipidemia and hepatic steatosis by enhancing fatty acid oxidation through activation of PPAR-α. Using wild type (WT, C57BL/6) fed with chow diet as control, WT mice were either fed with high-fat diet or high-fat diet with NDGA (2.5g/kg food); ob/ob mice were fed with either chow or chow with NDGA (2.5 g/kg food), and maintained on the respective diets for 16 weeks. The expression of lipid metabolism related genes in the liver of these mice were analyzed using Phalanx GPL6845 platform (Mouse OneArray V1). Together with other biochemical/physiological data, our results suggest that the beneficial actions of NDGA on dyslipidemia and hepatic steatosis in ob/ob mice are exerted primarily through enhanced fatty acid oxidation and energy utilization via the activation of PPAR- α receptor activity.

Hepatocyte-specific deletion of SIRT1 alters fatty acid metabolism

Project description:Hepatic metabolic derangements are key components in the development of fatty liver, insulin resistance, and atherosclerosis. SIRT1, a NAD+-dependent protein deacetylase, is an important regulator of energy homeostasis in response to nutrient availability. Here we demonstrate that hepatic SIRT1 regulates fatty acid metabolism by positively regulating PPAR-alpha. Hepatocyte-specific deletion of SIRT1 impairs PPAR-alpha signaling and decreased fatty acid beta-oxidation in the liver. When challenged with a high-fat diet, liver-specific SIRT1 knockout mice develop hepatic steatosis, hepatic inflammation, and endoplasmic reticulum stress. Taken together, our data indicate that SIRT1 plays a vital role in the regulation of hepatic lipid homeostasis.
