Increased accumulation of the advanced glycation endproduct Ne(carboxymethyl) lysine in the intramyocardial vasculature in patients with epicarditis. Int J Exp Pathol 2024; 105:48-51. [PMID: 38062984 PMCID: PMC10951421 DOI: 10.1111/iep.12499] [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: 08/08/2023] [Revised: 10/24/2023] [Accepted: 10/31/2023] [Indexed: 03/21/2024] Open
Abstract
Advanced glycation end-products (AGEs) are implicated in the pathogenesis of vascular disease. In previous studies we have found increased deposition of N(e)-(carboxymethyl)lysine (CML) in intramyocardial vasculature in the heart in acute myocardial infarction and myocarditis. It is known that the process of inflammation plays a role in the formation of AGEs. In this study we have explored the presence of CML (a major AGE) in the heart of patients with epicarditis using a monoclonal anti-CML antibody. Nine patients with epicarditis (n = 9) died and their hearts were used for this study, control were hearts from patients who died from conditions unrelated to heart disease and without signs of myocarditis or epicarditis CML deposition and complement were significantly increased in patients with epicarditis compared to control hearts. Thus epicarditis increases CML depositions in the intramyocardial vasculature.

Unlocking the miRNA-34a-5p/TGF-β and HMGB1/PI3K/Akt/mTOR crosstalk participate in the enhanced cardiac protection of liraglutide against isoproterenol-induced acute myocardial injury rat model. Int Immunopharmacol 2024; 127:111369. [PMID: 38101219 DOI: 10.1016/j.intimp.2023.111369] [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: 10/03/2023] [Revised: 11/07/2023] [Accepted: 12/10/2023] [Indexed: 12/17/2023]
Abstract
Liraglutide (LIRA), a drug used to treat type 2 diabetes mellitus that belongs to the glucagon-like peptide-1 class, has recently drawn attention for its potential cardioprotective properties because of its anti-oxidative and anti-inflammatory properties. This current investigation was designed to assess the impact of LIRA on myocardial injury induced by isoproterenol (ISO). The experiment included 24 male Wistar rats in total, and they were divided into four groups: Control, LIRA (200 µg/kg/12 hrs., S.C.), ISO (85 mg/kg, S.C.), and ISO + LIRA. To assess the results, various biochemical and histopathological analyses were carried out. The findings showed elevated serum enzyme levels, a sign of cardiac injury. ISO-treated rats showed an upregulation of oxidative stress and inflammatory biomarkers like MDA, MPO, nitrites, NADPH oxidase, TNF-α, IL-1β, IL-6, 8-Hydroxyguanosine (8-OHdG), and TGF-β, as well as altered gene expressions like TLR-1 and miRNA-34a-5p. According to western blotting analysis, protein levels of AKT, PI3K, and mTOR were obviously enhanced. Additionally, ISO-treated samples showed altered tissue morphology, elevated caspase 3, and decreased Bcl2 concentrations. The levels of these dysregulated parameters were significantly normalized by LIRA therapy, demonstrating its cardioprotective function against ISO-induced myocardial injury in rats. This protective mechanism was linked to anti-inflammatory properties, redox balance restoration, and modulation of the miRNA-34a-5p/TGF-β pathway.

Abstract
Valproic acid (VPA) is a commonly used drug for management of epilepsy. Prolonged VPA administration increases the risk of hepatotoxicity. Liraglutide is a glucagon-like peptide 1 receptor (GLP-1R) agonist that act as a novel antidiabetic drug with broad-spectrum anti-inflammatory and antioxidant effects. This study tested the protective effect of liraglutide against VPA-induced hepatotoxicity elucidating the possible underlying molecular mechanisms. Forty adult male rats were allocated in to four equally sized groups; Group I (control group) received oral distilled water and subcutaneous normal saline for 2 weeks followed by subcutaneous normal saline only for 2 weeks. Group II (liraglutide group) received subcutaneous liraglutide dissolved in normal saline daily for 4 weeks. Group III (valproic acid-treated group) received sodium valproate dissolved in distilled water for 2 weeks. Group IV (Combined valproic acid & liraglutide treated group) received valproic acid plus liraglutide daily for 2 weeks which was continued for additional 2 weeks after valproic acid administration. The hepatic index was calculated. Serum AST, ALT, GGT, and ALP activities were estimated. Hepatic tissue homogenate MDA, GSH, SOD, HMGB1, MAPK, RIPK1, and RIPK3 levels were evaluated using ELISA. However, hepatic RAGE and MLKL messenger RNA expression levels using the QRT-PCR technique. Hepatic NF-κB and TNF-α were detected immunohistochemically. Results proved that liraglutide coadministration significantly decreased liver enzymes, MDA, HMGB1, MAPK, RIPK1 RIPK3, RAGE, and MLKL with concomitant increased GSH and SOD in comparison to the correspondent values in VPA-hepatotoxicity group. Conclusions: Liraglutide's protective effects against VPA-induced hepatotoxicity are triggered by ameliorating oxidative stress, inflammation, and necroptosis.

Abstract
Diabetic vascular complications can affect both microvascular and macrovascular. Diabetic microvascular complications, such as diabetic nephropathy, diabetic retinopathy, diabetic neuropathy, and diabetic cardiomyopathy, are believed to be caused by oxidative stress. The Nox family of NADPH oxidases is a significant source of reactive oxygen species and plays a crucial role in regulating redox signaling, particularly in response to high glucose and diabetes mellitus. This review aims to provide an overview of the current knowledge about the role of Nox4 and its regulatory mechanisms in diabetic microangiopathies. Especially, the latest novel advances in the upregulation of Nox4 that aggravate various cell types within diabetic kidney disease will be highlighted. Interestingly, this review also presents the mechanisms by which Nox4 regulates diabetic microangiopathy from novel perspectives such as epigenetics. Besides, we emphasize Nox4 as a therapeutic target for treating microvascular complications of diabetes and summarize drugs, inhibitors, and dietary components targeting Nox4 as important therapeutic measures in preventing and treating diabetic microangiopathy. Additionally, this review also sums up the evidence related to Nox4 and diabetic macroangiopathy.

Abstract
Metabolic diseases, particularly diabetes mellitus (DM), are significant global public health concerns. Despite the widespread use of standard-of-care therapies, cardiovascular disease (CVD) remains the leading cause of death among diabetic patients. Early and evidence-based interventions to reduce CVD are urgently needed. Large clinical trials have recently shown that sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) ameliorate adverse cardiorenal outcomes in patients with type 2 DM. These quite unexpected positive results represent a paradigm shift in type 2 DM management, from the sole importance of glycemic control to the simultaneous improvement of cardiovascular outcomes. Moreover, SGLT2i is also found to be cardio- and nephroprotective in non-diabetic patients. Several mechanisms, which may be potentially independent or at least separate from the reduction in blood glucose levels, have already been identified behind the beneficial effect of these drugs. However, there is still much to be understood regarding the exact pathomechanisms. This review provides an overview of the current literature and sheds light on the modes of action of novel antidiabetic drugs, focusing on inflammation, oxidative stress, and fibrosis.

Front Pharmacol 2022; 13:979300. [PMID: 36353481 PMCID: PMC9639785 DOI: 10.3389/fphar.2022.979300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 09/29/2022] [Indexed: 11/23/2022] Open
Abstract
Background: Diabetes mellitus leads to endothelial dysfunction and accumulation of oxygen radicals. Sulfasalazine-induced Nrf2 activation reduces oxidative stress in vessels. Thus, in the present study, we investigated the effects of sulfasalazine on endothelial dysfunction induced by high glucose. We also ascribed the underlying mechanism involved in glucose-induced endothelial dysfunction. Methods: For this experiment we used 80 Wistar Albino rats thoracic aorta to calculate the dose response curve of noradrenaline and acetylcholine. Vessels were incubated in normal and high glucose for 2 h. To investigate glucose and sulfasalazine effects the vessels of the high glucose group were pre-treated with sulfasalazine (300 mM), JNK inhibitor (SP600125), and ERK inhibitor (U0126) for 30 min. The dose response curve was calculated through organ bath. The eNOS, TAS, TOS, and HO-1 levels were estimated by commercially available ELISA kits. Results: In the high glucose group, the Emax for contraction was significantly higher (p < 0.001), and Emax for relaxation was lower than that of control. These functional changes were parallel with the low levels of eNOS (p < 0.05). High glucose vessel treated with sulfasalazine showed low Emax value for contraction (p < 0.001) however, the Emax for relaxation was significantly high (p < 0.001) when compared to high glucose group. In the JNK group, Emax for contraction and relaxation was inhibited (p < 0.001) compared to sulfasalazine treated vessels. HO—1 enzyme levels were significantly low (p < 0.01) with sulfasalazine but higher with ERK inhibitor (p < 0.05). Conclusion: High glucose induced endothelial dysfunction and sulfasalazine reduced damage in high glucose vessels by activating eNOS, antioxidant effect through HO-1 enzymes and particularly inducing Nrf2 via the ERK and JNK pathways.
