[PMID: 37371762 DOI: 10.3390/biomedicines11061667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/31/2023] [Accepted: 06/06/2023] [Indexed: 06/29/2023] Open
Abstract
Recently, research has greatly expanded the knowledge of the endocannabinoid system (ECS) and its involvement in several therapeutic applications. Cannabinoid receptors (CBRs) are present in nearly every mammalian tissue, performing a vital role in different physiological processes (neuronal development, immune modulation, energy homeostasis). The ECS has an essential role in metabolic control and lipid signaling, making it a potential target for managing conditions such as obesity and diabetes. Its malfunction is closely linked to these pathological conditions. Additionally, the immunomodulatory function of the ECS presents a promising avenue for developing new treatments for various types of acute and chronic inflammatory conditions. Preclinical investigations using peripherally restricted CBR antagonists that do not cross the BBB have shown promise for the treatment of obesity and metabolic diseases, highlighting the importance of continuing efforts to discover novel molecules with superior safety profiles. The purpose of this review is to examine the roles of CB1R and CB2Rs, as well as their antagonists, in relation to the above-mentioned disorders.

Liraglutide Attenuates Hepatic Oxidative Stress, Inflammation, and Apoptosis in Streptozotocin-Induced Diabetic Mice by Modulating the Wnt/ β-Catenin Signaling Pathway. Mediators Inflamm 2023; 2023:8974960. [PMID: 36756089 PMCID: PMC9899592 DOI: 10.1155/2023/8974960] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 11/19/2022] [Accepted: 12/27/2022] [Indexed: 02/01/2023] Open
Abstract
Liraglutide has been extensively applied in the treatment of type 2 diabetes mellitus and also has hepatoprotective effects. However, the role of liraglutide treatment on liver injury in a mouse model of type 1 diabetes mellitus (T1DM) induced by streptozotocin (STZ) and its underlying mechanisms remain to be elucidated. In the present study, diabetes was initiated in experimental animals by single-dose intraperitoneal inoculation of STZ. Forty female C57BL/6J mice were equally assigned into five groups: diabetic group, insulin+diabetic group, liraglutide+diabetic group, insulin+liraglutide+diabetic group, and control group for eight weeks. Diabetic mice exhibited a significantly elevated blood glucose level and decreased body weight, and morphological changes of increased steatosis and apoptosis were observed in the liver compared with the control. Furthermore, a significant increase in the levels of malondialdehyde and inflammatory markers such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin 1β (IL-1β) and the proapoptotic proteins caspase-3 and Bax were observed in the livers of diabetic mice, together with marked increases in antioxidants superoxide dismutase (SOD) and glutathione peroxidase (GPX) as well as antiapoptotic protein Bcl-2, all of which were significantly mitigated by treatment with liraglutide, insulin, and their combinations. Interestingly, liraglutide monotherapy showed better efficacy in ameliorating liver injury in T1DM mice than insulin monotherapy, similar to the combined drug therapy. Furthermore, the expression of Wnt/β-catenin signaling pathway-associated molecules was upregulated in the liver of mice treated with liraglutide or insulin. The results of the present study suggested that liraglutide improves T1DM-induced liver injury and may have important implications for the treatment of nonalcoholic fatty liver disease (NAFLD) in patients with T1DM.

Abstract
In the modern era, sleep deprivation (SD) is one of the most common health problems that has a profound influence on an individual's quality of life and overall health. Studies have identified the possibility that lack of sleep can stimulate inflammatory responses. NLRP3 inflammasome, a key component of the innate immune responses, initiates inflammatory responses by enhancing proinflammatory cytokine release and caspase-1-mediated pyroptosis. In this study, NLRP3 modification, its proinflammatory role, and potential targeted therapies were reviewed with regard to SD-induced outcomes. A growing body of evidence has showed the importance of the mechanistic connections between NLRP3 and the detrimental consequences of SD, but there is a need for more clinically relevant data. In animal research, (i) some animals show differential vulnerability to the effects of SD compared to humans. (ii) Additionally, the effects of sleep differ depending on the SD technique employed and the length of SD. Moreover, paying attention to the crosstalk of all the driving factors of NLRP3 inflammasome activation such as inflammatory responses, autonomic control, oxidative stress, and endothelial function is highly recommended. In conclusion, targeting NLRP3 inflammasome or its downstream pathways for therapy could be complicated due to the reciprocal and complex relationship of SD with NLRP3 inflammasome activation. However, additional research is required to support such a causal claim.

Abstract
Diabetic peripheral neuropathy (DPN) is a common nerve disorder of diabetes. The aim of this study was to explore the protective effects of tropisetron in DPN. Type 1 diabetes was created by a single injection of streptozotocin (50 mg/kg, ip). Tropisetron (3 mg/kg, ip) was administered daily for 2 weeks. Our analysis showed that nerve fibers and their myelin sheaths were thinned with decreased myelinated fiber number in diabetic animals. The intensity of Bcl-2 staining decreased and the intensity of Bax staining increased in the sciatic nerves of diabetic rats by using immunohistochemical staining. Furthermore, diabetes significantly increased tumor necrosis factor-alpha, interleukin 1-β (TNFα and IL-1β) and Bax/Bcl-2 ratio in sciatic nerves of rats. However, intraperitoneal injection of tropisetron significantly reversed these alterations induced by diabetes. These findings suggest that tropisetron attenuates diabetes-induced peripheral nerve injury through its anti-inflammatory and anti-apoptotic effects, and may provide a novel therapeutic strategy to ameliorate the process of peripheral neuropathy in diabetes.

Abstract
Apoptosis is the main pathological aspect of neuronal injury after cerebral ischemia-reperfusion (I/R) injury. However the detailed molecular mediators are still under debate. The aim of this study is to explore the effect of cerebral I/R on miR-23a/TGF-β-activated kinase 1 binding protein 3 (TAB3)/nuclear factor kappa B (NF-κB)/p53 axis in rat hippocampus alone and in combination with chlorogenic acid (CGA). Common carotid artery occlusion (CCAO) was performed by nylon monofilament for 20 min to establish a model of ischemic brain injury. CGA (30 mg/kg) was administered intraperitoneally (ip), 10 min prior to ischemia and 10 min before reperfusion. Examination of hippocampus neurons by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining showed that the number of apoptotic neurons was elevated at 24 h after reperfusion. At the molecular levels, I/R injury resulted in an increased protein expression of p53 with a concomitant upregulation of cleaved-caspase3/phosphorelated-caspase3 ratio and cytochrome c level. Further miR-23b gene expression was significantly downregulated after 24 h of reperfusion. Also, we observed increased TAB3 and NF-κB protein expressions after 24 h following CCAO. Treatment with CGA significantly reduced the apoptotic damage and also reversed miR-23b gene expression, TAB3 and NF-κB protein expressions in hippocampus neurons in I/R rats. In conclusion our data suggest that miR-23b/TAB3/NF-κB/p53 axis could play a regulatory role in hippocampus cell death, which provide a new target for novel therapeutic interventions during transit ischemic stroke. It also demonstrated that CGA could reverse these molecular alterations indicating an effective component against hippocampus apoptotic insult following acute I/R injury.

Abstract
Background: Ondansetron is a preferred anti-emetic in critical care to treat nausea and vomiting, and has historically been considered a largely safe option. A recent pharmacoepidemiology study reported that ondansetron may be associated with an increased risk for acute kidney injury (AKI). Methods: We interrogated the High-Density Intensive Care (HiDenIC-15) database containing intensive care data for 13 hospitals across Western Pennsylvania between Oct 2008-Dec 2014. AKI was defined using the Kidney Disease, Improving Global Outcomes 2012 guidelines. Ondansetron use was considered as receiving any form of ondansetron within 24 h of admission. The subsequent 48 h (hours 25-72 after admission) were analyzed for outcomes. Primary outcome was development of AKI; secondary outcomes included 90-day mortality and time to AKI. Propensity-matched, multivariate logistic regression was applied for both outcomes. Comparator groups were metoclopramide and prochlorperazine using the same exposure criteria. Results:AKI occurred in 965 (5.6%), 12 (3.0%), and 61 (6.5%) patients receiving ondansetron, prochlorperazine, and metoclopramide, respectively. In the adjusted analysis, no anti-emetic was associated with a significant change in the odds of developing AKI. Ondansetron was associated with a 5.48% decrease (CI -6.17--4.79) in death within 90 days of ICU-admission, which was independent of AKI status; an effect not seen with other anti-emetics. Anti-emetic usage was not associated with a change in the time to first AKI. Conclusion:Anti-emetic usage did not alter AKI risk. Ondansetron was associated with a significant decrease in 90-day mortality that was not seen by other anti-emetics, which requires further exploration.

Abstract
Hyperglycemia-induced oxidative stress plays important roles in the development of non-alcoholic fatty liver disease (NAFLD), which is a common complication in diabetic patients. The Nrf2-Keap1 pathway is important for cell antioxidant protection, while its role in exogenous antioxidant mediated protection against NAFLD is unclear. We thus, postulated that antioxidant treatment with allopurinol (ALP) may attenuate diabetic liver injury and explored the underlying mechanisms. Control (C) and streptozotocin (STZ)-induced diabetes rats (D) were untreated or treated with ALP for 4 weeks starting at 1 week after diabetes induction. Serum levels of alanine aminotransferase (ALT) and aspartate transaminase (AST), production of lipid peroxidation product malondialdehyde (MDA), and serum superoxide dismutase (SOD) were detected. Liver protein expressions of cleaved-caspase 3, IL-1β, nuclear factor-erythroid-2-related factor-2 (Nrf2), heme oxygenase-1 (HO-1), P62, Kelch-like ECH-associated protein 1 (Keap1), and LC3 were analyzed. In vitro, cultured rat normal hepatocytes BRL-3A were grouped to normal glucose (5.5 mM, NG) or high glucose (25 mM, HG) and treated with or without allopurinol (100 µM) for 48 h. Rats in the D group demonstrated liver injury evidenced as increased serum levels of ALT and AST. Diabetes increased apoptotic cell death, enhanced liver protein expressions of cleaved-caspase 3 and IL-1β with concomitantly increased production of MDA while serum SOD content was significantly reduced (all P < 0.05 vs C). In the meantime, protein levels of Nrf2, HO-1, and P62 were reduced while Keap1 and LC3 were increased in the untreated D group as compared to control (P < 0.05 vs C). And all the above alterations were significantly attenuated by ALP. Similar to our findings obtained from in vivo study, we got the same results in in vitro experiments. It is concluded that ALP activates the Nrf2/p62 pathway to ameliorate oxidative stress and liver injury in diabetic rats.

Abstract
Background Ginkgo biloba extract 50 (GBE50) has a variety of pharmacological functions such as anti-inflammatory, antioxidant and maintenance of glucose and lipid metabolism homeostasis. However, the therapeutic effects and mechanisms of GBE50 on non-alcoholic fatty liver disease (NAFLD) remain unknown. Therefore, in this study, we evaluated the therapeutic effects of GBE50 in NAFLD by using a high-fat diet (HFD) mice model. Methods C57BL/6J mice were fed a HFD diet for 15 weeks and were given respectively 25, 50, and 100 mg/kg GBE50 daily by gavage from 3 to 15 weeks. After the administration, blood samples and liver tissues were collected for biochemical detection, histological measurement, immunohistochemistry and Western blot, respectively. Results We found that GBE50 treatment could ameliorate insulin resistance (IR), glucose intolerance, lipid accumulation, hepatic steatosis and liver injury in HFD-fed mice. Further mechanism exploration discovered that the hepatoprotective effects of GBE50 on NAFLD may be related to the strengthening of IRS-1 signal activation and the weakening of NF-κB, Akt and endoplasmic reticulum stress signals activation. Conclusion GBE50 is a potentially powerful therapeutic agent for the treatment of NAFLD.

Abstract
Liver failure is a severe clinical syndrome with high mortality. 5-Hydroxytryptamine 3 receptor antagonists (5-HT3RAs) can reduce liver damage in animal models. We investigated whether 5-HT3RAs may improve the prognosis of liver failure. We analyzed the 28 and 90 days mortality of liver failure patients in relation to the use of 5-HT3RAs using data from a tertiary hospital in northwest China. According to the use of 5-HT3RAs, 419 patients with liver failure (46 acute, 93 sub-acute, 44 chronic, 236 acute on chronic) were divided into 5-HT3RA group (n = 105) and control group (n = 314). 5-HT3RAs were associated with decreased 28 days (HR 0.18, 95% CI 0.10-0.34, p < 0.001) and 90 days (HR 0.21, 95% CI 0.13-0.33, p < 0.001) mortality. After propensity score matching (PSM) (n = 67 in each group), 5-HT3RAs were still significantly associated with reduced 28 days (HR 0.10, 95%CI 0.04-0.26, p < 0.001) and 90 days (HR 0.16, 95%CI 0.08-0.31, p < 0.001) mortality. 5-HT3RA group patients had significantly higher 28 and 90 days survivals than controls both before and after PSM (all p < 0.001). This study shows that 5-HT3RAs are associated with increased survival of liver failure patients and thus may be used to treat liver failure if the findings are confirmed by additional studies.

Basic Clin Pharmacol Toxicol 2021; 128:669-676. [PMID: 33523585 DOI: 10.1111/bcpt.13565] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 01/18/2021] [Accepted: 01/27/2021] [Indexed: 11/28/2022]
Abstract
Numerous documents have been stated that tropisetron, an antagonist of the 5-HT3 receptor and α7nAChR agonist, modulates immune responses. However, the mechanistic basis for this aspect of tropisetron action is largely unknown. Here, the immuno-modulatory effects of tropisetron are investigated, focusing on the possible molecular targets and the mechanisms. Aside from the well-characterized role in immune signalling, JAK2/STAT3, TLR2 and TLR4 are signal transducers linked to both immuno-modulatory actions of acetylcholine and serotonin. Therefore, we evaluated their involvement in the immunoregulatory effects of tropisetron. To test the hypothesis, we assessed the expression of pro-/anti-inflammatory cytokines including TNF-α, IL-1β, IL-17 and IL-10 following tropisetron treatment in lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMCs) derived from healthy subjects. Tropisetron up-regulates the transcription of TLR2, TLR4, JAK2 and STAT3 genes. Tropisetron also increases the expression of target pro-inflammatory cytokines, although considerably suppresses the pro-inflammatory cytokines (IL-1β, IL-17 and TNF-α) levels in media. Tropisetron notably promotes both IL-10 gene expression and secretion. These findings confirm the antiphlogistic properties of tropisetron. The present data also shed light on a new aspect of tropisetron immune-modulatory action that engaged TLR2, TLR4 and JAK2/STAT3 signalling cascades.

[PMID: 33047279 PMCID: PMC7736377 DOI: 10.1007/s12192-020-01170-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 09/29/2020] [Accepted: 10/01/2020] [Indexed: 12/21/2022] Open
Abstract
Tropisetron is a 5-HT3 receptor antagonist that exerts protective effect against DN. The aim of this study was to investigate the possible molecular mechanisms associated with the renoprotective effects of tropisetron in STZ-induced diabetic rats. Animals were subdivided into 5 equal groups; control, tropisetron, diabetes, tropisetron + diabetes, and glibenclamide + diabetes (n = 7). For induction of type 1 diabetes, a single injection of STZ (55 mg/kg, i.p.) was administered to the animals. Diabetic rats were treated with tropisetron (3 mg/kg) and glibenclamide (1 mg/kg) for 2 weeks. According to the conducted analysis, diabetes led to renal dysfunction (reduction in glomerular filtration rate and urine urea and creatinine as well as elevation in plasma urea and creatinine) and abnormalities in antioxidant defense system (reduction in TAC and elevation in MDA), compared with the control group, which was prevented by tropisetron treatment. Reverse transcription-quantitative polymerase chain reaction and western blotting analysis demonstrated that SIRT1 gene expression decreased while FOXO3a and NF-κB gene expression as well as phosphorylated FOXO3a/total FOXO3a protein ratios and claudin-1 protein level increased in the kidney of diabetic rats compared with the control group. Herein, the results of this research showed that tropisetron treatment reversed these changes. Besides, all these changes were comparable with those produced by glibenclamide as a positive control. Hence, tropisetron ameliorated renal damage due to diabetic nephropathy possibly by suppressing oxidative stress and alteration of SIRT1, FOXO3a, and claudin-1 levels.

J Cardiovasc Thorac Res 2020; 12:195-202.

Abstract
Introduction: microRNAs (miRs) play a critical role in both physiological and pathological processes. Recent studies have shown that garlic and exercise training have many beneficial effects in different disorders including cardiovascular disease. However, their mechanisms have not been fully understood. This study sought to investigate the impact of garlic and voluntary training alone or together on themiR-126 and miR-210 gene expressions and cardiac angiogenesis. Methods: Male Wistar rats were divided into four groups (n=7): (1) Control, (2) Garlic, (3) Exercise, and (4) Garlic+ Exercise. Animals were gavaged with raw fresh garlic homogenate (250 mg/kg body weight/day) or were subjected to voluntary training alone or together for about 6 weeks. The expressions of miR-126 and miR-210 in the heart tissue were measured by real-time PCR and lipid profile in serum was assessed by enzymatic kits. Angiogenesis was determined by immuno staining detection of PECAM-1 and CD31 in the heart tissue. Results: Garlic and exercise up-regulated myocardial miR-126 (P < 0.01), miR-210 (P < 0.001)expressions, and angiogenesis (P < 0.001) which was evidenced by higher CD31 expression. Besides, combination of garlic and exercise amplified their effects on those parameters (P < 0.001). Moreover, both voluntary exercise and garlic alone (P < 0.01) or together (P < 0.001) markedly modulated serum lipid profile. Conclusion: Voluntary exercise and garlic treatment for 6 weeks enhanced myocardial angiogenesis. These alterations were partly due to the increment of miR-126 and miR-210 expressions in the heart tissue in relation to improvement in lipid profile.

Abstract
Testicular damage contributes to cyclosporine A (CsA) induced male infertility. However, the exact underlying molecular mediators involved in CsA-induced testis disorder remains unclear. The present study aimed to characterize the role of mir-34a/sirt-1 in CsA induced testicular injury alone or in combination with curcumin. A total of twenty-eight male Wistar rats were subdivided into four groups: control (Con), sham, cyclosporine A (CsA), cyclosporineA + curcumin (CsA + cur). The animals received cyclosporine A (30 mg/kg) and curcumin (40 mg/kg) for 28 days by oral gavage. At the end of the experiment, CsA administration significantly resulted in a decrease in testis weight and testis coefficient. The molecular analysis demonstrated that CsA exposure increased 8-OHdg and Nox4 protein contents in the testis tissue. TUNEL staining indicated that CsA caused the number of apoptotic cells to increase in the testes of male rats. In addition, exposure to CsA resulted in an increased expression of Bax, and a decreased expresion in that of Bcl-2, with a concomitant up-regulation of the Bax/Bcl-2, c-Caspase-3/p-Caspase-3 ratio and cytochrome c level. Meanwhile, exposure to CsA increased the expression of mir-34a and decreased sirt-1 protein level in the testis tissue samples compared to the control group. Taken together, our findings suggested that CsA can cause damage to testicular germ cells via oxidative stress and mitochondrial apoptotic pathway, and probably mir-34a/sirt-1 play a crucial role in this process. It also demonstrates that these negative effects of CsA can be reduced by using curcumin as an antioxidant and anti-inflammatory agent.

Abstract
Objectives There is an association between diabetes and liver disorders. Oxidative stress plays a crucial role in the pathology of hepatic abnormalities in diabetes. In this study, the effect of Tropisetron on the oxidative damage and histological alterations in the liver of type 1 diabetes mellitus (DM) were evaluated. Methods Thiry-five male Wistar rats were randomly divided into five experimental groups (n = 7): control (C), tropisetron (T), diabetes (D), diabetes + tropisetron (D + T) and diabetes + glibenclamide (D + G). A single injection of streptozotocin (STZ, 50 mg/kg; i.p) was used to induce diabetes. Tropisetron (3 mg/kg; i.p), as a 5-HT3 receptor antagonist and glibenclamide (1 mg/kg; i.p), as a positive control were given once daily for 2 weeks. Finally, animals were euthanized and liver samples were obtained for histopathological examination and biochemical measurements including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) levels. Results There is a significant increase in MDA (p < 0.001) level and a significant decrease (p < 0.001) in SOD and GPx contents in diabetic animals. Tropisetron attenuated MDA levels (p < 0.001) and enhanced SOD (p < 0.05) and GPx (p < 0.01) activities accompanied by histopathological improvement in the diabetes liver. Similar results were achieved in the rats treated with the standard drug, namely: glibenclamide. Conclusions Our findings indicate that tropisetron mitigates liver damage in the diabetes rats in part by attenuation of oxidative stress.
