A fluorinated peptide with high serum- and lipid-tolerence for the delivery of siRNA drugs to treat obesity and metabolic dysfunction
Biomaterials. 2022 Apr 28;285:121541. doi: 10.1016/j.biomaterials.2022.121541. Online ahead of print.ABSTRACTObesity is the major risk factor for metabolic diseases such as fatty liver, hyperlipidemia and insulin resistance. Beige fat has been recognized as a therapeutic target considering its great potential to burn energy. Since the evolutionary discovery of RNA interference and its utilization for gene knockdown in mammalian cells, a remarkable progress has been achieved in siRNA-based therapeutics. However, efficient delivery of siRNA into adipose tissues or differentiated adipocytes is challenging due to high lipid co...

CD98 siRNA-loaded nanoparticles decrease hepatic steatosis in mice
Non-alcoholic fatty liver disease (NAFLD) is characterized by excessive lipid hepatic accumulation. Here, we investigated whether a reduction of CD98 expression mediated by CD98 siRNA-loaded nanoparticles (NPs) could attenuate liver disease markers in a mouse model of NAFLD. NPs were generated using a double emulsion/solvent evaporation technique. Mice fed a high fat diet for 8 weeks to induce fatty liver were treated with vein tail injections of CD98 siRNA-loaded NPs. In vitro, HepG2 treated with CD98 siRNA-loaded NPs showed significant downregulation of CD98 leading to a significant decrease of major pro-inflammatory cytokines and markers.

Tangshen Formula Alleviates Hepatic Steatosis by Inducing Autophagy Through the AMPK/SIRT1 Pathway
Conclusion In conclusion, the present study demonstrated that autophagy was involved in relieving the effects of TSF against NAFLD, which were mediated by the AMPK/SIRT1 pathway (Figure 7D). These findings may improve our current understanding of the role of TSF in treating hepatic steatosis and provide an experimental basis for the clinical application of TSF in NAFLD and its related metabolic syndrome. Ethics Statement This study was carried out in accordance with the recommendations in the Guide for the Care and Use of Laboratory Animals of the National Institutes of Health. The protocol was approved by the Ethics Co...

Glucagon‐like peptide‐1 (GLP‐1) preserves non‐alcoholic fatty liver disease (NAFLD) through inhibition of the endoplasmic reticulum (ER) stress‐associated pathway
ConclusionGLP‐1 protected against non‐alcoholic fatty liver disease by inactivating the ER stress‐associated apoptosis pathway. In addition, the effect was possibly related to the signaling pathway of ERp46. This article is protected by copyright. All rights reserved.

Inhibition of citrate cotransporter Slc13a5/mINDY by RNAi improves hepatic insulin sensitivity and prevents diet-induced non-alcoholic fatty liver disease in mice
Conclusions We show that inducible mINDY inhibition improved hepatic insulin sensitivity and prevented diet-induced non-alcoholic fatty liver disease in adult C57BL6/J mice. These effects did not depend on changes of body weight or body composition. Graphical abstract

Cytochrome P450 1A1 (CYP1A1) Catalyzes Lipid Peroxidation of Oleic Acid-Induced HepG2 Cells
AbstractNonalcoholic fatty liver disease (NAFLD) is a chronic hepatic disease associated with excessive accumulation of lipids in hepatocytes. As the disease progresses, oxidative stress plays a pivotal role in the development of hepatic lipid peroxidation. Cytochrome P450 1A1 (CYP1A1), a subtype of the cytochrome P450 family, has been shown to be a vital modulator in production of reactive oxygen species. However, the exact role of CYP1A1 in NAFLD is still unclear. The aim of this study was to investigate the effects of CYP1A1 on lipid peroxidation in oleic acid (OA)-treated human hepatoma cells (HepG2). We found that the...

Effect of celastrol on toll ‑like receptor 4‑mediated inflammatory response in free fatty acid‑induced HepG2 cells.
Effect of celastrol on toll‑like receptor 4‑mediated inflammatory response in free fatty acid‑induced HepG2 cells. Int J Mol Med. 2018 Jul 12;: Authors: Han LP, Sun B, Li CJ, Xie Y, Chen LM Abstract Toll‑like receptor 4 (TLR4)‑mediated immune and inflammatory signaling serves a pivotal role in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). Our previous study demonstrated that celastrol treatment was able to improve hepatic steatosis and inhibit the TLR4 signaling cascade pathway in type 2 diabetic rats. The present study aimed to investigate the effects of celastrol on trigly...

CYP1A2 contributes to alcohol-induced abnormal lipid metabolism through the PTEN/AKT/SREBP-1c pathway.
In this study, we aimed to explore the role of CYP1A2 in lipid metabolism abnormalities induced by alcohol and to investigate the underlying mechanisms. L02 cells were treated with siRNA-CYP1A2 or fluvoxamine and then stimulated with 100 mM ethanol for 24 h. The levels of ALT and TGs in the siRNA-CYP1A2 and fluvoxamine groups were significantly lower than those in the normal control group after ethanol treatment, and the expression of SREBP-1c was decreased when CYP1A2 was inhibited, suggesting that CYP1A2 may contribute to alcohol-induced irregular lipid metabolism by regulating sterol regulatory element-binding prote...

Isoquercitrin activates the AMP-activated protein kinase (AMPK) signal pathway in rat H4IIE cells
Conclusions: Isoquercitrin appears to regulate AMPK activation, thereby enhancing AdipoR1 expression, suppressing SREBP-1 and FAS expressions, and resulting in the regulation of lipid accumulation. These results suggest that isoquercitrin is a novel dietary compound that can be potentially be used to prevent lipid metabolic disorder and nonalcoholic fatty liver disease.
