Modulation of the crosstalk between Keap1/Nrf2/HO-1 and NF-κB signaling pathways by Tomatidine protects against inflammation/oxidative stress-driven fulminant hepatic failure in mice. Int Immunopharmacol 2024; 130:111732. [PMID: 38402834 DOI: 10.1016/j.intimp.2024.111732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 02/09/2024] [Accepted: 02/18/2024] [Indexed: 02/27/2024]
Abstract
Fulminant hepatic failure (FHF) is the terminal phase of acute liver injury, which is characterized by massive hepatocyte necrosis and rapid hepatic dysfunction in patients without preexisting liver disease. There are currently no therapeutic options for such a life-threatening hepatic failure except liver transplantation; therefore, the terminal phase of the underlying acute liver injury should be avoided. Tomatidine (TOM), asteroidal alkaloid, may have different biological activities, including antioxidant and anti-inflammatory effects. Herein, the lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-induced FHF mouse model was established to explore the protective potential of TOM and the underlying mechanisms of action. TOM pretreatment significantly inhibited hepatocyte necrosis and decreased serum aminotransferase activities in LPS/D-GalN-stimulated mice. TOM further increased the level of different antioxidant enzymes while reducing lipid peroxidation biomarkers in the liver. These beneficial effects of TOM were shown to be associated with targeting of NF-κB signaling pathways, where TOM repressed NF-κB activation and decreased LPS/D-GalN-induced TNF-α, IL-6, IL-1β, and iNOS production. Moreover, TOM prevented LPS/D-GalN-induced upregulation of Keap1 expression and downregulation of Nrf2 and HO-1 expression, leading to increased Nrf2-binding activity and HO-1 levels. Besides, TOM pretreatment repressed LPS/D-GalN-induced upregulation of proliferating cell nuclear antigen (PCNA) expression, which spared the hepatocytes from damage and subsequent repair following the LPS/D-GalN challenge. Collectively, our findings revealed that TOM has a protective effect on LPS/D-GalN-induced FHF in mice, showing powerful antioxidant and anti-inflammatory effects, primarily mediated via modulating Keap1/Nrf2/HO-1 and NF-κB/TNF-α/IL-6/IL-1β/iNOS signaling pathways.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 120:155059. [PMID: 37672856 DOI: 10.1016/j.phymed.2023.155059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 07/28/2023] [Accepted: 08/29/2023] [Indexed: 09/08/2023]
Abstract
BACKGROUND Fulminant hepatic failure (FHF) lacks efficient therapies notwithstanding increased comprehending of the inflammatory response and oxidative stress play crucial roles in the pathogenesis of this type of hepatic damage. Trilobatin (TLB), a naturally occurring food additive, is endowed with anti-inflammation and antioxidant properties. PURPOSE In current study, we evaluated the effect of TLB on FHF with a mouse model with d-galactosamine/lipopolysaccharide (GalN/LPS)-induced FHF and LPS-stimulated Kupffer cells (KCs) injury. METHODS Mice were randomly divided into seven groups: control group, TLB 40 mg/kg + control group, GalN/LPS group, TLB 10 mg/kg + GalN/LPS group, TLB 20 mg/kg + GalN/LPS group, TLB 40 mg/kg + GalN/LPS group, bifendate 150 mg/kg + GalN/LPS group. The mice were administered intragastrically TLB (10, 20 and 40 mg/kg) for 7 days (twice a day) prior to injection of GalN (700 mg/kg)/LPS (100 µg/kg). The KCs were pretreated with TLB (2.5, 5, 10 μM) for 2 h or its analogue (10 μM) or COX2 inhibitor (10 μM), and thereafter challenged by LPS (1 μg/ml) for 24 h. RESULTS TLB effectively rescued GalN/LPS-induced FHF. Furthermore, TLB inhibited TLR 4/NLRP3/pyroptosis pathway, and caspase 3-dependent apoptosis pathway, along with reducing excessive cellular and mitochondrial ROS generation and enhancing mitochondrial biogenesis. Intriguingly, TLB directly bound to COX2 as reflected by transcriptomics, molecular docking technique and surface plasmon resonance assay. Furthermore, TLB failed to attenuate LPS-induced inflammation and oxidative stress in KCs in the absence of COX2. CONCLUSION Our findings discover a novel pharmacological effect of TLB: protecting against FHF-induced pyroptosis and apoptosis through mediating ROS/TLR4/NLRP3 signaling pathway and reducing inflammation and oxidative stress. TLB may be a promising agent with outstanding safety profile to treat FHF.

Abstract
BACKGROUND Liver damage is a global health concern associated with a high mortality rate. Sodium benzoate (SB) is a widely used preservative in the food industry with a wide range of applications. However, there's a lack of scientific reports on its effect on lipopolysaccharide-induced hepatic dysfunction. OBJECTIVE The present study investigated the influence of SB on lipopolysaccharide (LPS)-induced liver injury. MATERIALS AND METHODS Twenty-eight rats were randomly allocated into four groups: control (received distilled water), SB (received 600 mg/kg), LPS (received 0.25 mg/kg), and LPS + SB (received LPS, 0.25 mg/kg, and SB, 600 mg/kg). SB was administered orally for 14 days while LPS was administered intraperitoneally for 7 days. RESULTS Administration of SB to rats with hepatocyte injury exacerbated liver damage with a significant increase in the activities of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). We also observed that SB aggravated LPS-mediated hepatic oxidative stress occasioned by a marked decrease in antioxidant status with a concomitant increase in lipid peroxidation. Furthermore, LPS - mediated increase in inflammatory biomarkers as well as histological deterioration in the liver was exacerbated following the administration of SB to rats. CONCLUSION Taken together, the study provides experimental evidence that SB exacerbates hepatic oxidative stress and inflammation in LPS-mediated liver injury.

Scavenging of reactive oxygen species can adjust the differentiation of tendon stem cells and progenitor cells and prevent ectopic calcification in tendinopathy. Acta Biomater 2022; 152:440-452. [PMID: 36108965 DOI: 10.1016/j.actbio.2022.09.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 08/31/2022] [Accepted: 09/05/2022] [Indexed: 11/22/2022]
Abstract
Tendinopathy is a common disorder that leads to pain and impaired quality of life. Recent studies revealed that osteogenic differentiation of tendon stem/progenitor cells (TSPCs) played an important role in the pathogenesis of tendon calcification and tendinopathy. In this study, we found that the growth hormone-releasing hormone agonist (GA) can prevent matrix degradation and osteogenic differentiation in TSPCs. As oxidative stress is a key factor in the osteogenic differentiation of TSPCs, we used bovine serum albumin/heparin nanoparticles (BHNPs), which have biocompatibility and drug loading capacity, to scavenge reactive oxygen species (ROS) and achieve sustained release of GA at the site of inflammation. The newly developed BHNPs@GA had a synergetic effect on reducing ROS production in TSPCs. In addition, BHNPs@GA effectively inhibited tendon calcification and promoted collagen formation in a rat model of tendinopathy. Focusing on the ROS underlying the differentiation and dedifferentiation of TSPCs, this work demonstrated that sustained release of GA targeting ROS and ectopic ossification is a practical therapeutic strategy for treating tendinopathy. STATEMENT OF SIGNIFICANCE: Osteogenic differentiation of tendon stem/progenitor cells (TSPCs) plays an important role in the pathogenesis of ectopic calcification in tendinopathy. In this study, we found that growth hormone-releasing hormone agonist (GA) can reduce reactive oxygen species (ROS) production and adjust TSPCs differentiation. Bovine serum albumin/heparin nanoparticles (BHNPs) were developed to encapsulate GA and achieve sustained release of GA at the site of inflammation. The developed compound, BHNPs@GA, with a synergistic effect of inhibiting ROS and thus, can effectively adjust TSPCs differentiation, inhibit tendon calcification, and promote collagen formation in tendinopathy. This study highlighted the role of ROS underlying the differentiation and dedifferentiation of TSPCs in tendinopathy, and findings may help to identify new therapeutic targets and develop novel strategy for treating tendinopathy.

Basic Properties of a New Polymer Gel for 3D-Dosimetry at High Dose-Rates Typical for FFF Irradiation Based on Dithiothreitol and Methacrylic Acid (MAGADIT): Sensitivity, Range, Reproducibility, Accuracy, Dose Rate Effect and Impact of Oxygen Scavenger. Polymers (Basel) 2019; 11:polym11101717. [PMID: 31635117 PMCID: PMC6835276 DOI: 10.3390/polym11101717] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 09/27/2019] [Accepted: 10/10/2019] [Indexed: 12/18/2022] Open
Abstract
The photon induced radical-initiated polymerization in polymer gels can be used for high-resolution tissue equivalent dosimeters in quality control of radiation therapy. The dose (D) distribution in radiation therapy can be measured as a change of the physical measurement parameter T2 using T2-weighted magnetic resonance imaging. The detection by T2 is relying on the local change of the molecular mobility due to local polymerization initiated by radicals generated by the ionizing radiation. The dosimetric signals R2 = 1/T2 of many of the current polymer gels are dose-rate dependent, which reduces the reliability of the gel for clinical use. A novel gel dosimeter, based on methacrylic acid, gelatin and the newly added dithiothreitol (MAGADIT) as an oxygen-scavenger was analyzed for basic properties, such as sensitivity, reproducibility, accuracy and dose-rate dependence. Dithiothreitol features no toxic classification with a difference to THPC and offers a stronger negative redox-potential than ascorbic acid. Polymer gels with three different concentration levels of dithiothreitol were irradiated with a preclinical research X-ray unit and MR-scanned (T2) for quantitative dosimetry after calibration. The polymer gel with the lowest concentration of the oxygen scavenger was about factor 3 more sensitive to dose as compared to the gel with the highest concentration. The dose sensitivity (α = ∆R2/∆D) of MAGADIT gels was significantly dependent on the applied dose rate D˙ (≈48% reduction between D˙ = 0.6 Gy/min and D˙ = 4 Gy/min). However, this undesirable dose-rate effect reduced between 4–8 Gy/min (≈23%) and almost disappeared in the high dose-rate range (8 ≤ D˙≤ 12 Gy/min) used in flattening-filter-free (FFF) irradiations. The dose response varied for different samples within one manufacturing batch within 3%–6% (reproducibility). The accuracy ranged between 3.5% and 7.9%. The impact of the dose rate on the spatial integrity is demonstrated in the example of a linear accelerator (LINAC) small sized 5 × 10 mm2 10 MV photon field. For MAGADIT the maximum shift in the flanks in this field is limited to about 0.8 mm at a FFF dose rate of 15 Gy/min. Dose rate sensitive polymer gels likely perform better at high dose rates; MAGADIT exhibits a slightly improved performance compared to the reference normoxic polymer gel methacrylic and ascorbic acid in gelatin initiated by copper (MAGIC) using ascorbic acid.

Abstract
Reactive oxygen species (ROS) have been shown to have a role in inflammation. We investigated whether Forsythia suspensa extract (FSE) could exert its antioxidant potential against lipopolysaccharide (LPS)-induced inflammatory liver injury in rats. Rats were orally fed FSE once daily for 7 consecutive days prior to LPS (Escherichia coli, serotype O55:B5) injection. LPS treatment caused liver dysfunction as evidenced by massive histopathological changes and increased serum alanine aminotransferase and aspartate aminotransferase activities which were ameliorated by FSE pretreatment. FSE attenuated LPS-induced depletion of cytosolic nuclear factor-erythroid 2-related factor 2 (Nrf2) and suppression of Nrf2 nuclear translocation in liver, and the generation of ROS and malondialdehyde in serum and liver. FSE increased the Nrf2-mediated induction of heme oxygenase-1 in liver, as well as superoxide dismutase and glutathione peroxidase activities in serum and liver. Importantly, FSE attenuated LPS-induced nuclear factor-кB (NF-кB) nuclear translocation in liver, and subsequently decreased tumor necrosis factor-α, interleukin (IL)-1β and IL-6 levels in serum and liver, which were associated with FSE-induced activation of Nrf2 in liver. These results indicate that the protective mechanisms of FSE may be involved in the attenuation of oxidative stress and the inhibition of the NF-кB-mediated inflammatory response by modulating the Nrf2-mediated antioxidant response against LPS-induced inflammatory liver injury.

Abstract
To inhibit hepatic ischemia/reperfusion injury, we developed polyethylene glycol (PEG) conjugated (PEGylated) cysteine-modified lysine dendrimers with multiple reduced thiols, which function as scavengers of reactive oxygen species (ROS). Second, third, and fourth generation (K2, K3, and K4) highly branched amino acid spherical lysine dendrimers were synthesized, and cysteine (C) was conjugated to the outer layer of these lysine dendrimers to obtain K2C, K3C, and K4C dendrimers. Subsequently, PEG was reacted with the C residues of the dendrimers to obtain PEGylated dendrimers with multiple reduced thiols (K2C-PEG, K3C-PEG, and K4C-PEG). Radiolabeled K4C-PEG ((111)In-K4C-PEG) exhibited prolonged retention in the plasma, whereas (111)In-K2C-PEG and (111)In-K3C-PEG rapidly disappeared from the plasma. K4C-PEG significantly prevented the elevation of plasma alanine aminotransferase (ALT) activity, an index of hepatocyte injury, in a mouse model of hepatic ischemia/reperfusion injury. In contrast, K2C-PEG, K3C-PEG, l-cysteine, and glutathione, the latter two of which are classical reduced thiols, hardly affected the plasma ALT activity. These findings indicate that K4C-PEG with prolonged circulation time is a promising compound to inhibit hepatic ischemia/reperfusion injury.

Abstract
Biological proteins have unlimited potential for use as pharmaceutical products due to their various biological activities, which include non-toxicity, biocompatibility, and biodegradability. Recent scientific advances allow for the development of novel innovative protein-based products that draw on the quality of their innate biological activities. Some of them hold promising potential for novel therapeutic agents/devices for addressing hepatic diseases such as hepatitis, fibrosis, and hepatocarcinomas. This review attempts to provide an overview of the development of protein-based products that take advantage of their biological activity for medication, and discusses possibilities for the therapeutic potential of protein-based products produced through different approaches to specifically target the liver (or hepatic cells: hepatocytes, hepatic stellate cells, liver sinusoidal endothelial cells, and Kupffer cells) in the treatment of hepatic diseases.

Abstract
To establish a rational molecular design for bisphosphonate (BP)-modified proteins for efficient bone targeting, a pharmacokinetic study was performed using a series of alendronate (ALN), a nitrogen-containing BP, modified proteins with various molecular weights and varying degrees of modification. Four proteins with different molecular weight—yeast glutathione reductase (GR; MW: 112,000 Da), bovine serum albumin (BSA; MW: 67,000 Da), recombinant human superoxide dismutase (SOD; MW: 32,000 Da), and chicken egg white lysozyme (LZM; MW: 14,000 Da)—were modified with ALN to obtain ALN-modified proteins. Pharmacokinetic analysis of the tissue distribution of the ALN-modified and unmodified proteins was performed after radiolabeling them with indium-111 (111In) by using a bifunctional chelating agent. Calculation of tissue uptake clearances revealed that the bone uptake clearances of 111In-ALN-modified proteins were proportional to the degree of ALN modification. 111In-GR-ALN and BSA-ALN, the two high-molecular-weight proteins, efficiently accumulated in bones, regardless of the degree of ALN modification. Approximately 36 and 34% of the dose, respectively, was calculated to be delivered to the bones. In contrast, the maximum amounts taken up by bone were 18 and 13% of the dose for 111In-SOD-ALN(32) and LZM-ALN(9), respectively, because of their high renal clearance. 111In-SOD modified with both polyethylene glycol (PEG) and ALN (111In-PEG-SOD-ALN) was efficiently delivered to the bone. Approximately 36% of the dose was estimated to be delivered to the bones. In an experimental bone metastasis mouse model, treatment with PEG-SOD-ALN significantly reduced the number of tumor cells in the bone of the mice. These results indicate that the combination of PEG and ALN modification is a promising approach for efficient bone targeting of proteins with a high total-body clearance.

Abstract
Modification with poly(ethylene glycol) (PEG) is a widely used method for the prolongation of plasma half-life of colloidal carrier systems such as nanoparticles prepared from human serum albumin (HSA). However, the quantification of the PEGylation extent is still challenging. Moreover, the influence of different PEG derivatives, which are commonly used for nanoparticle conjugation, has not been investigated so far. The objective of the present study is to develop a method for the quantification of PEG and to monitor the influence of diverse PEG reagents on the amount of PEG linked to the surface of HSA nanoparticles. A size exclusion chromatography method with refractive index detection was established which enabled the quantification of unreacted PEG in the supernatant. The achieved results were confirmed using a fluorescent PEG derivative, which was detected by photometry and fluorimetry. Additionally, PEGylated HSA nanoparticles were enzymatically digested and the linked amount of fluorescently active PEG was directly determined. All the analytical methods confirmed that under optimized PEGylation conditions a PEGylation efficiency of up to 0.5 mg PEG per mg nanoparticle could be achieved. Model calculations made a 'brush' conformation of the PEG chains on the particle surface very likely. By incubating the nanoparticles with fetal bovine serum the reduced adsorption of serum proteins on PEGylated HSA nanoparticles compared to non-PEGylated HSA nanoparticles was demonstrated using sodium dodecylsulfate polyacrylamide gel electrophoresis. Finally, the positive effect of PEGylation on plasma half-life was demonstrated in an in vivo study in mice. Compared to unmodified nanoparticles the PEGylation led to a four times larger plasma half-life.
