Abstract
Chronic liver injury due to various etiological factors results in excess secretion and accumulation of extracellular matrix proteins, leading to scarring of liver tissue and ultimately to hepatic fibrosis. If left untreated, fibrosis might progress to cirrhosis and even hepatocellular carcinoma. Thymoquinone (TQ), an active compound of Nigella sativa, has been reported to exhibit antioxidant, anti-inflammatory and anticancer activities. Therefore, the effect of TQ against thioacetamide (TAA)-induced liver fibrosis was assessed in rats. Fibrosis was induced with intraperitoneal administration of TAA (250 mg/kg b.w.) twice a week for 5 weeks. TQ (20 mg/kg b.w.) and silymarin (50 mg/kg b.w.) were orally administered daily for 5 weeks separately in TAA administered groups. Liver dysfunction was reported by elevated liver enzymes, increased oxidative stress, inflammation and fibrosis upon TAA administration. Our study demonstrated that TQ inhibited the elevation of liver marker enzymes in serum. TQ administration significantly increased antioxidant markers, such as superoxide dismutase, catalase, glutathione, glutathione peroxidase and glutathione reductase in the liver tissue of rats. Further, TQ significantly attenuated liver fibrosis, as illustrated by the downregulation of TAA-induced interleukin-β, tumour necrosis factor-α, inducible nitric oxide synthase and fibrosis markers like transforming growth factor-β (TGF-β), α-smooth muscle actin, collagen-1, Smad3 and 7. Therefore, these findings suggest that TQ has a promising hepatoprotective property, as indicated by its potential to effectively suppress TAA-induced liver fibrosis in rats by inhibiting oxidative stress and inflammation via TGF-β/Smad signaling.

Abstract
Carcinogenic food-borne liver fluke infections are a serious epidemiological threat worldwide. The major complications of Opisthorchis felineus infection are chronic inflammation and biliary intraepithelial neoplasia. Although evidence has accumulated that increased reactive oxygen species production is observed in liver fluke infection, a direct relationship between the oxidative stress and biliary intraepithelial neoplasia has not been shown. Quinones and SkQ1, a derivative of plastoquinone, have been demonstrated to be cytoprotective in numerous liver injuries due to their potent antioxidant properties. This study is aimed to assess the level of biliary intraepithelial neoplasia in O. felineus-infected hamsters after treatment with mitochondria-targeted SkQ1. SkQ1 significantly reduced the biliary intraepithelial neoplasia, which was accompanied by a decrease in lipid and DNA oxidation byproducts, mRNA expression and level of proteins associated with inflammation (TNF-α, CD68) and fibrogenesis (CK7, αSMA), and was also associated with an activation of the Keap1-Nrf2 pathway. Thus, a direct relationship was found between oxidative stress and the severity of biliary intraepithelial neoplasia in O. felineus-infected hamsters. The hepatoprotective effect of plastoquinone-derivative SkQ1 was established; therefore, this compound is a promising agent in complex therapy in the treatment of opisthorchiasis.

Abstract
BACKGROUND AND AIMS Efficacy evaluations with preclinical magnetic resonance imaging (MRI) are uncommon, but MRI in the preclinical phase of drug development provides information that is useful for longitudinal monitoring. The study aim was to monitor the protective effectiveness of silymarin with multiparameter MRI and biomarkers in a thioacetamide (TAA)-induced model of liver injury in rats. Correlation analysis was conducted to assess compare the monitoring of liver function by MRI and biomarkers. METHODS TAA was injected three times a week for 8 weeks to generate a disease model (TAA group). In the TAA and silymarin-treated (TAA-SY) groups, silymarin was administered three times weekly from week 4. MR images were acquired at 0, 2, 4, 6, and 8 weeks in the control, TAA, and TAA-SY groups. RESULTS The area under the curve to maximum time (AUCtmax) and T2* values of the TAA group decreased over the study period, but the serological markers of liver abnormality increased significantly more than those in the control group. In the TAA-SY group, MRI and serological biomarkers indicated attenuation of liver function as in the TAA group. However, pattern changes were observed from week 6 to comparable levels in the control group with silymarin treatment. Negative correlations between either AUCtmax or T2* values and the serological biomarkers were observed. CONCLUSIONS Silymarin had hepatoprotective effects on TAA-induced liver injury and demonstrated the usefulness of multiparametric MRI to evaluate efficacy in preclinical studies of liver drug development.

The significance of thymoquinone administration on liver toxicity of diazinon and cholinesterase activity; a recommendation for prophylaxis among individuals at risk. BMC Complement Med Ther 2022; 22:321. [PMID: 36464690 PMCID: PMC9720986 DOI: 10.1186/s12906-022-03806-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 11/22/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Diazinon (DZN), a widely used chemical herbicide for controlling agricultural pests, is an important organophosphorus pesticide and an environmental pollutant which induces toxic effects on living organisms during long-term exposure. Thymoquinone (TQ) is a phytochemical bioactive compound with antioxidant and anti-inflammatory properties. We aimed to evaluate the protective effects of TQ against DZN-induced hepatotoxicity through alleviating oxidative stress and enhancing cholinesterase (ChE) enzyme activity. METHODS Rats were randomly divided into six groups (n = 8); a negative control group receiving corn oil; a group only receiving DZN (20 mg/kg/day); a group treated with TQ (10 mg/kg/day), and three treatment groups as TQ + DZN, receiving different doses of TQ (2.5, 5, and 10 mg/kg/day). All experimental animals were orally treated for 28 consecutive days. The levels of superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), alanine transaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and lactic acid dehydrogenase (LDH) were determined. In addition, ChE activity and histopathological changes were evaluated. RESULTS The results showed that DZN decreased GSH level (p < 0.01) and SOD activity (p < 0.01) in parallel to an increase in MDA level (p < 0.01) and increased the activity of AST, ALT, ALP, and LDH (p < 0.01) in comparison to the negative control group. Our findings demonstrated that TQ administration could diminish hepatotoxicity and reduce oxidative damage in DZN-treated rats, which could be linked to its antioxidant and free radical scavenging properties. It was also observed that TQ 10 mg/kg remarkably increased the activity of acetylcholinesterase, butyrylcholinesterase, and SOD enzymes, elevated GSH, decreased MDA, and reduced pathological alternations of the liver induced by DZN. CONCLUSION Thymoquinone 10 mg/kg increased the activity of plasma and blood cholinesterases and reduced DZN-induced alternations of the liver. Improvement of butyryl- and acetylcholinesterase activity suggests that maybe TQ supplement could be beneficial as pre-exposure prophylaxis among farm workers spraying pesticides.

Abstract
The protective effects of chlorogenic acid (CGA) against liver injury were evaluated by its reduction in carbon tetrachloride (CCl4)-induced hepatic damage in ICR mice. The animals were orally given CGA (60, 100, and 200 mg/kg, respectively) or silymairn (200 mg/kg) daily with 0.3% CCl4 administration (3 mL/kg, dissolved in olive oil) after medicament treatment on the 7th day. Compared with the normal group, CCl4 caused severe impairment in liver according to the evidence of significant reduction in the level of total albumin and expansion (p < 0.05) of the activities in aspartate aminotransferase (AST) and alanine aminotransferase (ALT), cholesterol, triglyceride (TG), and total albumin in serum, decreased the level of glutathione (GSH), and diminished the activities of catalase, superoxide dismutase (SOD), glutathione reductase (GSH-Rd), and glutathione peroxidase (GSH-Px) in liver while increasing the level of hepatic thiobarbituric acid-reactive substances (TBARS). However, oral administration of CGA or silymarin could significantly (p < 0.05) decrease the serum levels of AST, ALT, cholesterol, TG, and total albumin and elevated the serum total albumin and the activities of GSH, catalase, SOD, GSH-Rd, and GSH-Px while leading to decline the TBARS in liver compared with CCl4-intoxicated group. Moreover, histopathology displayed that CGA decreased the formation of lesions in liver resulted from CCl4. The outcomes indicate that CGA shows the efficiency hepatoprotective consequences for CCl4-incited liver injuries in mice by the elevation of the activities of antioxidant enzymes and hindrance of lipid peroxidation.

Abstract
Thymoquinone (TQ; 2-isopropyl-5-methylbenzo-1, 4-quinone), the main active constituent of Nigella sativa, has been proven to have great therapeutic properties in numerous in vivo and in vitro models. Nevertheless, this molecule is not yet in clinical trials, largely because of its poor bioavailability and hydrophobicity. This review examines the different activities of TQ, as well as various combination therapies, nanotechnologies and clinical trials involving TQ. The TQ nanoparticle formulation shows better bioavailability than free TQ, and it is time for clinical trials of these formulations to realize the potential of TQ as a therapeutic.

Abstract
D-galactose (D-gal) administration causes oxidative disorder and is widely utilized in aging animal models. Therefore, we subcutaneously injected D-gal at 200 mg/kg BW dose to assess the potential preventive effect of thymoquinone (TQ) and curcumin (Cur) against the oxidative alterations induced by D-gal. Other than the control, vehicle, and D-gal groups, the TQ and Cur treated groups were orally supplemented at 20 mg/kg BW of each alone or combined. TQ and Cur effectively suppressed the oxidative alterations induced by D-gal in brain and heart tissues. The TQ and Cur combination significantly decreased the elevated necrosis in the brain and heart by D-gal. It significantly reduced brain caspase 3, calbindin, and calcium-binding adapter molecule 1 (IBA1), heart caspase 3, and BCL2. Expression of mRNA of the brain and heart TP53, p21, Bax, and CASP-3 were significantly downregulated in the TQ and Cur combination group along with upregulation of BCL2 in comparison with the D-gal group. Data suggested that the TQ and Cur combination is a promising approach in aging prevention.

Abstract
Although valproic acid (VPA) is a low-cost and effective drug, it is known to cause organ toxicity via oxidative stress and related process. In present study, we aimed to evaluate the possible protective effects of thymoquinone (TMQ) on VPA-induced testicular toxicity. Male Sprague-Dawley rats were divided into three as control, VPA (500 mg kg-1 day-1 ) for 14 days and VPA plus TMQ (50 mg kg-1 day-1 for 14 days) with seven rats in. Spermatic and interstitial degenerations induced by VPA were ameliorated with TMQ. In VPA group, increased TOS and OSI levels, and decreased TAS level were seen. TMQ reversed these oxidative stress parameters significantly. In Western analysis, VPA was found to increase the expressions of phospho-nuclear factor kappa beta (p-Nf-kB) and Caspase-3. These expressions were decreased by TMQ significantly. Intense immunostaining for p-Nf-kB, Caspase-3 and NADPH oxidase 2 induced by VPA were transformed to moderate immunostaining by TMQ. VPA-induced inflammation and apoptosis that were developed mainly by p-Nf-kB pathway were attenuated by TMQ. TMQ can be a candidate supportive treatment for patients who need long-term and high-dose VPA therapy. TMQ inhibits the Nf-kB activation, and in addition to antioxidant property, it shows anti-inflammatory feature on VPA-induced testicular toxicity.

Abstract
Background: Thymoquinone (TQ) is a safe nutrient isolated from the seeds or volatile oil extract of Nigella sativa. In addition to its benefits in glucose regulation, TQ improves feeding disorders in diabetic animals. Glucagon-like peptide-1 (GLP-1) analogs improve glycemic control and ameliorate obesity or hyperphagia. Therefore, the present study aimed to investigate the role of GLP-1 in TQ-induced anorexia. Method: Type 2 diabetes was induced in rats by nicotinamide and streptozotocin injection. TQ was orally administered to diabetic rats at different doses for 45 days. Following TQ treatment, changes in serum glucose levels, GLP-1 concentration, body weight, food intake, and water intake were determined. To further explore the interaction between GLP-1 and TQ, the inhibitor of dipeptidyl peptidase 4, sitagliptin and the GLP-1 receptor antagonist exendin 9-39 (Ex 9-39) were separately administered to TQ- or vehicle-treated diabetic rats. Results: TQ treatment attenuated hyperglycemia and reduced hyperphagy and water intake in streptozotocin-induced diabetic rats in a dose-dependent manner. Moreover, TQ treatment elevated plasma GLP-1 levels compared to those in control rats. The effects of TQ were enhanced by treatment with sitagliptin and reduced by the injection of Ex 9-39 into the brain. In contrast, similar treatment with another antioxidant (either ascorbic acid or N-acetylcysteine) produced the same anorexic effect as TQ without changing the plasma GLP-1 levels in diabetic rats. Therefore, TQ attenuated hyperphagy while increasing plasma GLP-1 levels and had antioxidant-like effects. Conclusion: TQ increased endogenous GLP-1 levels to reduce hyperphagy in diabetic rats.
