Abstract
The specific miRNA regulation triggered by enzyme-treated soybean protein in response to well-known stressors, such as the prophylactic use of the antimicrobial oxytetracycline, remains unknown. Hence, this study aimed to evaluate the regulatory changes of hepatic miRNAs induced by oxytetracycline and enzyme-treated soybean protein in largemouth bass dietary formulations. The experiment was designed with three groups: the normal control (NC), the oxytetracycline exposure treatment group (OTC), and the pre-treatment with enzyme-treated soybean protein before oxytetracycline exposure group (ETSP). miRNA sequencing was employed to characterize the differences between these groups. In conclusion, the NC group exhibited up-regulation of 13 host miRNAs and down-regulation of 1 miRNA compared to the OTC group, whereas the ETSP group showed an increasing trend of 36 host miRNAs and a decreasing trend of 13 host miRNAs compared to the OTC group. Nine miRNAs were identified as prudential targets for enzyme-treated soy protein, protecting the largemouth bass liver from oxytetracycline. Furthermore, gene ontology analysis revealed nine key miRNAs that mediate signaling pathways with significant differences. The cellular lipid metabolic process was identified as the most important biological process, and the propanoate metabolism pathway was highlighted as significant. These results will facilitate further exploration of the mechanism by which enzyme-treated soy protein alleviates the effects of oxytetracycline on largemouth bass in water environments.

Oxytetracycline-induced oxidative liver damage by disturbed mitochondrial dynamics and impaired enzyme antioxidants in largemouth bass (Micropterus salmoides). AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2023; 261:106616.

Abstract
Oxytetracycline (OTC), a commonly used tetracycline antibiotic in aquaculture, has been found to cause significant damage to the liver of largemouth bass (Micropterus salmoides). This study revealed that OTC can lead to severe histopathological damage, structural changes at the cellular level, and increased levels of reactive oxygen species (ROS) in M. salmoides. Meanwhile, OTC impairs the activities of antioxidant enzyme (such as T-SOD, CAT, GST, GR) by suppressing the activation of MAPK/Nrf2 pathway. OTC disrupts mitochondrial dynamics and mitophagy through via PINK1/Parkin pathway. The accumulation of damaged mitochondria, combined with the inhibition of the antioxidant enzyme system, contributes to elevated ROS levels and oxidative liver damage in M. salmoides. Further investigations demonstrated that an enzyme-treated soy protein (ETSP) dietary supplement can help maintain mitochondrial dynamic balance by inhibiting the PINK1/Parkin pathway and activate the MAPK/Nrf2 pathway to counteract oxidative damage. In summary, these findings highlight that exposure to OTC disrupts mitochondrial dynamics and inhibits the antioxidant enzyme system, ultimately exacerbating oxidative liver damage in M. salmoides. We propose the use of a dietary supplement as a preventive measure against OTC-related side effects, providing valuable insights into the mechanisms of antibiotic toxicity in aquatic environments.

Abstract
Autoimmune liver disease is a chronic liver disease caused by an overactive immune response in the liver that imposes a significant health and economic cost on society. Due to the side effects of existing medicinal medications, there is a trend toward seeking natural bioactive compounds as dietary supplements. Currently, dietary polyphenols have been proven to have the ability to mediate gut-liver immunity and control autoimmune liver disease through modulating the intestinal microenvironment. Based on the preceding, this Review covers the many forms of autoimmune liver illnesses, their pathophysiology, and the modulatory effects of polyphenols on immune disorders. Finally, we focus on how polyphenols interact with the intestinal milieu to improve autoimmune liver disease. In conclusion, we suggest that dietary polyphenols have the potential as gut-targeted modulators for the prevention and treatment of autoimmune liver disease and highlight new perspectives and critical issues for future pharmacological applications.

Abstract
Quercetin is a kind of flavonoid compounds that comes from nature and is widely existed in the daily diet. Previous studies have found that quercetin has many effects such as anti-inflammatory, anti-oxidation and anti-cancer. Both in vivo and in vitro experiments have demonstrated that quercetin can exert anti-tumor effects by altering cell cycle progression, inhibiting cell proliferation, promoting apoptosis, inhibiting angiogenesis and metastasis progression, and affecting autophagy. This review summarizes the evidence for the pharmacological potential and inhibition of quercetin on cancers, supporting the viewpoint that quercetin should be adequately considered as a therapeutic agent against various cancers.

Abstract
The ability of quercetin to reverse an established cirrhosis has not yet been investigated. Therefore, the aim of this study was to examine the efficacy of this flavonoid in reversing experimental cirrhosis. Cirrhosis was induced by intraperitoneal administration of TAA (200 mg/kg of body weight) three times per week for 8 weeks or by intraperitoneal petrolatum-CCl4 (400 mg/kg of body weight) administration three times per week for 8 weeks. To determine the capacity of quercetin to prevent liver fibrosis, the flavonoid (50 mg/kg of body weight, p.o.) was administered daily to rats during the CCl4 or TAA treatment. To evaluate the ability of quercetin to reverse the previously induced cirrhosis, we first treated rats with CCl4 for 8 weeks, as previously described and then the flavonoid was administered for four more weeks. We found that the liver anti-inflammatory and antinecrotic effects of quercetin are associated with its antioxidant properties, to the ability of the flavonoid to block NF-κB activation and in consequence to reduce cytokine IL-1. The ability of quercetin to reverse fibrosis may be associated with the capacity of the flavonoid to decrease TGF-β levels, hepatic stellate cell activation, and to promote degradation of the ECM by increasing metalloproteinases. The main conclusion is that quercetin, in addition to its liver protective activity against TAA chronic intoxication, is also capable of reversing a well-stablished cirrhosis by blocking the prooxidant processes and by downregulating the inflammatory and profibrotic responses.

Free Radic Biol Med 2015; 85:12-23.

Abstract
Quercetin, one of the most abundant dietary flavonoids, is reported to have protective function against various hepatotoxicant-induced hepatotoxicity. The present study aims to investigate the critical role of the nuclear factor erythroid 2-related factor 2 (Nrf2) antioxidative signaling pathway in the protection of quercetin against hepatotoxicity. Quercetin prevented the cytotoxicity induced by a variety of hepatotoxicants including clivorine (Cliv), acetaminophen (APAP), ethanol, carbon tetrachloride (CCl4), and toosendanin (TSN) in human normal liver L-02 cells. Quercetin induced the nuclear translocation of Nrf2, along with the increased expression of the antioxidant responsive element (ARE)-dependent genes like catalytic or modify subunit of glutamate-cysteine ligase (GCLC/GCLM), and heme oxygenase-1 (HO-1). In addition, the HO-1 inhibitor zinc protoporphyrin (ZnPP) and the GCL inhibitor L-buthionine-(S,R)-sulfoximine (BSO) both reduced the hepatoprotection induced by quercetin. Quercetin had no effect on kelch-like ECH-associated protein-1(Keap1) expression, but molecular docking results indicated the potential interaction of quercetin with the Nrf2-binding site in Keap1 protein. Quercetin increased the expression of p62, and p62 siRNA decreased quercetin-induced hepatoprotection. Quercetin induced the activation of c-Jun N-terminal kinase (JNK) in hepatocytes. JNK inhibitor SP600125 and JNK siRNA both reduced quercetin-induced hepatoprotection. SP600125 and JNK siRNA decreased the increased p62 expression induced by quercetin. In addition, SP600125 also decreased the increased mRNA and protein expression of GCLC, GCLM, and HO-1 induced by quercetin. Taken together, our present study demonstrates that quercetin prevents hepatotoxicity by inducing p62 expression, inhibiting the binding of Keap1 to Nrf2, and thus leading to the increased expression of antioxidative genes dependent on Nrf2. Meanwhile, our study indicates that JNK plays some regulation in this process.

Abstract
Bile duct obstruction and subsequent cholestasis are associated with hepatocellular injury, cholangiocyte proliferation, stellate cell activation, Kupffer cell activation, oxidative stress, inflammation and fibrosis. Flavonoids have been shown to confer beneficial health effects, including hepatoprotection. However, the molecular mechanism of flavonoid-mediated hepatoprotection is incompletely understood. In this study, we report the protective effect of quercetin on cholestatic liver injury. Cholestasis was produced by bile duct ligation (BDL) in male Sprague-Dawley rats for 3 weeks. Daily oral administration of quercetin was started 1 week before injury and lasted for 4 weeks. In comparison with the control group, the BDL group showed liver injury, as evidenced by histological changes, and elevation in serum biochemicals, ductular reaction, fibrosis, inflammation and oxidative stress. These pathophysiological changes were attenuated by daily quercetin supplementation. Quercetin alleviated BDL-induced transforming growth factor beta-1 (TGF-β1), interleukin-1 beta, connective tissue growth factor and collagen expression. The antifibrotic effect of quercetin was accompanied by reductions in α-smooth muscle actin-positive matrix-producing cells and Smad 2/3 activity critical to the fibrogenic potential of TGF-β1. Quercetin also attenuated BDL-induced oxidative stress, leukocyte accumulation, nuclear factor (NF)-κB activation and proinflammatory cytokine production. Further studies demonstrated an inhibitory effect of quercetin on MyD88 and TGF-β-activated kinase-1 critical for linking toll-like receptor (TLR) and NF-κB. Taken together, the hepatoprotective, anti-inflammatory and antifibrotic effects of quercetin seem to be multifactorial. The beneficial effects of daily quercetin supplementation are associated with antioxidative and anti-inflammatory potential as well as down-regulation of NF-κB and TGF-β/Smad signaling, probably via interference with TLR signaling.

Abstract
OBJECTIVE To investigate the protective effect of quercetin (QE), an anti-inflammatory and anti-oxidant agent, on torsion-detorsion induced histopathological changes and blood IMA levels in experimental ovarian ischemia-reperfusion (IR) injury. STUDY DESIGN Twenty-four female Wistar rats were randomly divided into four groups in this study (n=6). Group I, (sham operation); Group II, torsion-detorsion plus saline (IR); Group III, torsion-detorsion plus solvent (dimethylsulfoxide: DMSO, IR+DMSO); Group IV, torsion-detorsion plus 15 mg/kg/bw quercetin (IR+QE) injected intraperitoneally 30 min prior to detorsion. After 3h of reperfusion, the right ovaries were removed surgically. The ovary tissue samples were fixed in 10% formalin solution for histopathological and immunohistochemical examination. Blood samples were obtained at the end of the procedures for each group of animals. RESULTS Ovarian sections in Groups II and III showed higher follicular cell degeneration, hemorrhage, vascular congestion and edema when compared with Group I. Administration of quercetin in rats significantly prevented degenerative changes in the ovary. Significantly less histopathological changes were found in Group IV compared with Groups II and III. Caspase-3 and TUNEL positive cells were detected in the ovarian surface, follicle epithelium, and stromal cells in all experimental groups, and there was a significant increase in Groups II and III compared with Group I (P<0.05). Treatment with quercetin decreased the number of caspase-3 and TUNEL positive cells. IR increased the ischemia modified albumin (IMA) levels in comparison to the sham group (1.06 ± 0.10 ABSU and 0.92 ± 0.08 ABSU, P<0.05). Quercetin administration before IR reduced the levels of IMA (0.93 ± 0.08 ABSU, P<0.05). CONCLUSION Administration of quercetin is effective in preventing tissue damage induced by IR injury in ovaries.

Abstract
PURPOSE To evaluate the effect of bioflavonoid ternatin (TRT) on rat liver regeneration and oxidative stress after 70% partial hepatectomy (PH). METHODS Thirty six young male Wistar rats were randomly assigned to two groups of 18 animals each - control (G1) and experimental (G2) - and were submitted to PH under inhalatory diethylether anesthesia. G1 rats received daily intraperitoneal (ip) injections of saline (NaCl 0.9% solution) 0.1 mL/kg for 14 days; G2 animals received daily ip injections of TRT 0.1% 1.0mg/kg for 14 days. At 36h (T1), 168h (T2) and 336h (T3) post-PH timepoints, a subgroup of six rats in each group was chosen in a randomized way to complementary hepatectomy (CH) and blood samples haversting. Collected material was saved for laboratory analysis (total bilirubin (TB), D-Glucose, glutathione (GSH) and thiobarbituric acid reactive substances (TBARS) and assessment of liver regeneration. RESULTS TRT induced a significant decrease in liver and plasma GSH concentrations; liver regeneration process was not affected. TRT promoted a significant decrease in blood glucose levels 168h after partial hepatectomy compared with controls. TB levels remained unchanged. CONCLUSION Intraperitoneal bioflavonoid ternatin injection in partially hepatectomized rats induces a decrease in oxidative stress and a significant hypoglycemic state, but does not promote any change in the evolution of liver regeneration.

Abstract
BACKGROUND The aim of this study was to evaluate the preventive and therapeutic potential of hyperbaric oxygen therapy (HBO) on the liver tissue against bile duct ligation (BDL)-induced oxidative damage and fibrosis in rats. MATERIALS AND METHODS We divided 32 adult male Sprague Dawley rats into four groups: sham, sham plus HBO, BDL, and BDL plus HBO; each group contained eight animals. We placed the sham plus HBO and BDL plus HBO groups in an experimental hyperbaric chamber in which we administered pure oxygen at 2.5 atmospheres absolute 100% oxygen for 90 min on 14 consecutive days. RESULTS The application of BDL clearly increased the tissue malondialdehyde level, myeloperoxidase activity, and hydroxyproline content and decreased the antioxidant enzymes (superoxide dismutase and catalase activities) and glutathione level. Hyperbaric oxygen therapy treatment significantly decreased the elevated tissue malondialdehyde level, myeloperoxidase activity, and hydroxyproline content and increased the reduced superoxide dismutase and catalase activities and glutathione level in the tissues. The changes demonstrating the bile duct proliferation and fibrosis in expanded portal tracts include the extension of proliferated bile ducts into lobules, mononuclear cells, and neutrophil infiltration into the widened portal areas were observed in BDL group. Treatment of BDL with HBO attenuated alterations in liver histology. Alpha smooth muscle actin, cytokeratin-positive ductular proliferation, and the activity of terminal deoxynucleotidyl transferase 2'-deoxyuridine, 5'-triphosphate nick end labeling in the BDL decreased with HBO treatment. CONCLUSIONS The data indicate that HBO attenuates BDL-induced oxidative injury, hepatocytes damage, bile duct proliferation, and fibrosis. The hepatoprotective effect of HBO is associated with antioxidative potential.

Abstract
The goal of this study was to evaluate the possible protective effects of melatonin against cholestatic oxidative stress, liver damage and hepatocyte apoptosis in the common rats with bile duct ligation (BDL). A total of 24 male Wistar albino rats were divided into three groups: control, BDL and BDL + received melatonin; each group contains eight animals. Melatonin-treated BDL rats received daily melatonin 100 mg/kg/day via intraperitoneal injection. The application of BDL clearly increased the malondialdehyde (MDA) levels and decreased the superoxide dismutase (SOD) and glutathione (GSH) activities. Melatonin treatment significantly decreased the elevated tissue MDA levels and increased the reduced SOD and GSH enzyme levels in the tissues. The changes demonstrate that the bile duct proliferation and fibrosis in expanded portal tracts include the extension of proliferated bile ducts into lobules, mononuclear cells and neutrophil infiltration into the widened portal areas as observed in the BDL group. The data indicate that melatonin attenuates BDL-induced cholestatic liver injury, bile duct proliferation and fibrosis. The α-smooth muscle actin (α-SMA) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-positive cells in the BDL were observed to be reduced with the melatonin treatment. These results suggest that administration of melatonin is a potentially beneficial agent to reduce liver damage in BDL by decreasing oxidative stress.

Abstract
PURPOSE To investigate the possible protective role of the bioflavonoid ternatin (TTN) when administered before induction of ischemia/reperfusion injury in rat testis. METHODS Thirty-six Wistar rats were randomly assigned to 3 groups (n=12), divided in 2 subgroups (n=6). Saline 2.0ml (G-1), dimethylsulfoxide (DMSO) 3% solution (G-2) or TTN 12 mg/kg/dose (G-3) was administered ip. to all rats, respectively, 21, 12 and 1 hour before torsion. Anesthetized rats were subjected to ischemia (3 hours) induced by 720º torsion of the spermatic cord. Right testis and arterial blood samples were collected at the end of ischemia (T-0), and 3 hours later (T-3) for assessment of testis malonaldehyde (MDA), reduced glutathione (GSH), and plasma total antioxidant power (TAP). RESULTS MDA decreased significantly (p<0,001) in G-2 and G-3 in T-0 and T-3 timepoints. Additional decrease in MDA was seen in G-3 after 3 hours of reperfusion (T-3). GSH increased significantly in G-2 (p<0.001) and G-3 (p<0.05) at the end the ischemia (T-0). A significant increase in GSH was seen 3 hours after testis detorsion (T-3) in G-2 rats. TAP values remained unchanged. CONCLUSION The data provides in vivo evidence of the antiperoxidative and antioxidative properties of TTN in torted rat testis.

Abstract
The aim of this study was to examine the preventive and therapeutic effects of thymoquinone (TQ) against cholestatic oxidative stress and liver damage in common bile duct ligated rats. A total of 24 male Sprague-Dawley rats were divided into three groups: control, bile duct ligation (BDL) and BDL + received TQ; each group contain 8 animals. The rats in TQ treated groups were given TQ (50 mg/kg body weight) once a day orally for 2 weeks starting 3 days prior to BDL operation. To date, no more biochemical and histopathological changes on common bile duct ligated rats by TQ treatment have been reported. The application of BDL clearly increased the tissue hydroxyproline (HP) content, malondialdehyde (MDA) levels and decreased the antioxidant enzyme [superoxide dismutase (SOD), glutathione peroxidase (GPx)] activities. TQ treatment significantly decreased the elevated tissue HP content, and MDA levels and raised the reduced of SOD, and GPx enzymes in the tissues. The changes demonstrating the bile duct proliferation and fibrosis in expanded portal tracts include the extension of proliferated bile ducts into lobules, mononuclear cells, and neutrophil infiltration into the widened portal areas were observed in BDL group. Treatment of BDL with TQ attenuated alterations in liver histology. The immunopositivity of alpha smooth muscle actin and proliferating cell nuclear antigen in BDL were observed to be reduced with the TQ treatment. The present study demonstrates that oral administration of TQ in bile duct ligated rats maintained antioxidant defenses and reduces liver oxidative damage and ductular proliferation. This effect of TQ may be useful in the preservation of liver function in cholestasis.

Abstract
The aim of this study was designed to evaluate the possible protective effects of quercetine (QE) on the neuronal injury in the frontal cortex after chronic toluene exposure in rats. The rats were randomly allotted into one of the three experimental groups, namely, groups A (control), B (toluene treated) and C (toluene-treated with QE), where each group contains 10 animals. Control group received 1 ml of normal saline solution, and toluene treatment was performed by the inhalation of 3000 ppm toluene in an 8-h/day and 6-day/week order for 12 weeks. The rats in QE-treated group was given QE (15 mg/kg body weight) once a day intraperitoneally for 12 weeks, starting just after toluene exposure. Tissue samples were obtained for histopathological investigation. To date, no histopathological changes of neurodegeneration in the frontal cortex after chronic toluene exposure in rats by QE treatment have been reported. In this study, the morphology of neurons in the QE treatment group was well protected. Chronic toluene exposure caused severe degenerative changes, shrunken cytoplasm and extensively dark picnotic nuclei in neurons of the frontal cortex. We conclude that QE therapy causes morphologic improvement in neurodegeneration of frontal cortex after chronic toluene exposure in rats. We believe that further preclinical research into the utility of QE may indicate its usefulness as a potential treatment on neurodegeneration after chronic toluene exposure in rats.

Abstract
The aim of this study was to evaluate the possible protective effects of caffeic acid phenethyl ester (CAPE) against cholestatic oxidative stress and liver damage in the common bile duct ligated rats. A total of 18 male Sprague-Dawley rats were divided into three groups: control, bile duct ligation (BDL) and BDL + received CAPE; each group contain 6 animals. The rats in CAPE treated groups were given CAPE (10 μmol/kg) once a day intraperitoneally (i.p) for 2 weeks starting just after BDL operation. The changes demonstrating the bile duct proliferation and fibrosis in expanded portal tracts include the extension of proliferated bile ducts into lobules, inflammatory cell infiltration into the widened portal areas were observed in BDL group. Treatment of BDL with CAPE attenuated alterations in liver histology. The proliferating cell nuclear antigen and the activity of TUNEL in the BDL were observed to be reduced with the QE treatment. The application of BDL clearly increased the tissue hydroxyproline (HP) content, malondialdehyde (MDA) levels and decreased the antioxidant enzyme (superoxide dismutase (SOD), glutathione peroxidase (GPx)) activities. CAPE treatment significantly decreased the elevated tissue HP content, and MDA levels and raised the reduced of SOD, and GPx enzymes in the tissues. The data indicate that CAPE attenuates BDL-induced cholestatic liver injury, bile duct proliferation, and fibrosis. The hepatoprotective effect of CAPE is associated with antioxidative potential.
