Biochim Biophys Acta Gen Subj 2024; 1868:130564. [PMID: 38272191 DOI: 10.1016/j.bbagen.2024.130564] [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: 12/05/2023] [Revised: 01/01/2024] [Accepted: 01/12/2024] [Indexed: 01/27/2024]
Abstract
Selenium (Se) is involved in many physiopathologic processes in humans and animals and is strongly associated with the development of heart disease. Lipopolysaccharides (LPS) are cell wall components of gram-negative bacteria that are present in large quantities during environmental pollution. To investigate the mechanism of LPS-induced cardiac injury and the efficacy of the therapeutic effect of SeMet on LPS, a chicken model supplemented with selenomethionine (SeMet) and/or LPS treatment, as well as a primary chicken embryo cardiomyocyte model with the combined effect of SeMet / JAK2 inhibitor (INCB018424) and/or LPS were established in this experiment. CCK8 kit, Trypan blue staining, DCFH-DA staining, oxidative stress kits, immunofluorescence staining, LDH kit, real-time fluorescence quantitative PCR, and western blot were used. The results proved that LPS exposure led to ROS explosion, hindered the antioxidant system, promoted the expression of the JAK2 pathway, and increased the expression of genes involved in the pyroptosis pathway, inflammatory factors, and heat shock proteins (HSPs). Upon co-treatment with SeMet and LPS, SeMet reduced LPS-induced pyroptosis and inflammation and restored the expression of HSPs by inhibiting the ROS burst and modulating the antioxidant capacity. Co-treatment with INCB018424 and LPS resulted in inhibited of the JAK2 pathway, attenuating pyroptosis, inflammation, and high expression of HSPs. Thus, LPS induced pyroptosis, inflammation, and changes in HSPs activity by activating of the JAK2 / STAT3 / A20 signaling axis in chicken hearts. Moreover, SeMet has a positive effect on LPS-induced injury. This work further provides a theoretical basis for treating cardiac injury by SeMet.

A review of the epidemiological and laboratory evidence of the role of aluminum exposure in pathogenesis of cardiovascular diseases. ENVIRONMENTAL RESEARCH 2024; 242:117740. [PMID: 38007081 DOI: 10.1016/j.envres.2023.117740] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 11/13/2023] [Accepted: 11/18/2023] [Indexed: 11/27/2023]
Abstract
The objective of the present study was to review the epidemiological and laboratory evidence on the role of aluminum (Al) exposure in the pathogenesis of cardiovascular diseases. Epidemiological data demonstrated an increased incidence of cardiovascular diseases (CVD), including hypertension and atherosclerosis in occupationally exposed subjects and hemodialysis patients. In addition, Al body burden was found to be elevated in patients with coronary heart disease, hypertension, and dyslipidemia. Laboratory studies demonstrated that Al exposure induced significant ultrastructural damage in the heart, resulting in electrocardiogram alterations in association with cardiomyocyte necrosis and apoptosis, inflammation, oxidative stress, inflammation, and mitochondrial dysfunction. In agreement with the epidemiological findings, laboratory data demonstrated dyslipidemia upon Al exposure, resulting from impaired hepatic lipid catabolism, as well as promotion of low-density lipoprotein oxidation. Al was also shown to inhibit paraoxonase 1 activity and to induce endothelial dysfunction and adhesion molecule expression, further promoting atherogenesis. The role of Al in hypertension was shown to be mediated by up-regulation of NADPH-oxidase, inhibition of nitric oxide bioavailability, and stimulation of renin-angiotensin-aldosterone system. It has been also demonstrated that Al exposure targets cerebral vasculature, which may be considered a link between Al exposure and cerebrovascular diseases. Findings from other tissues lend support that ferroptosis, pyroptosis, endoplasmic reticulum stress, and modulation of gut microbiome and metabolome are involved in the development of CVD upon Al exposure. A better understanding of the role of the cardiovascular system as a target for Al toxicity will be useful for risk assessment and the development of treatment and prevention strategies.

Abstract
BACKGROUND AND AIMS Atherosclerosis as a chronic inflammatory disorder of the arterial wall is the main leading cause of the cardiovascular disease (CVD). Caspase-dependent pyroptosis plays a pivotal role in the pathogenesis of CVD. Selenium (Se) is an important component of the antioxidant defense and plays a crucial role in cardiovascular health. This study aimed to investigate the effects of daily consumption of sodium selenite and Se-enriched yeast on the expression of pyroptosis-related genes, and biomarkers of oxidative stress in patients with atherosclerosis. METHODS AND RESULTS In this randomized, double-blinded, placebo-controlled clinical trial, 60 patients with atherosclerosis were recruited. Participants received 200 μg/day of sodium selenite, Se-enriched yeast, or placebo for 8 following weeks. The pyroptosis-related genes' mRNA expression in peripheral blood mononuclear cells (PBMCs) was assessed before and after the intervention. Also, the levels of superoxide dismutase (SOD), malondialdehyde (MDA), nitric oxide (NO), and glutathione peroxidases (GPX) were measured at baseline and following the intervention. Following sodium selenite and Se-enriched yeast supplementation, the relative expression levels of TLR4, ASC, NLRP3, and NF-κB1 were significantly downregulated (p < 0.05). Furthermore, the changes in GPX were significantly increased after selenite and yeast supplementation (p < 0.05). Also, selenite and yeast consumption caused a statistically significant decrease in the change of MDA level (p < 0.05). CONCLUSION In summary, these findings showed that Se supplementation may reduce inflammation through down-regulation of some pro-inflammatory genes, improving antioxidant defenses in atherosclerosis patients. Further research is required to come to a definite conclusion of selenium supplementation on the CVD risk. This study was registered on the Iranian Registry of Clinical Trials website (identifier: RCT20110123005670N28; https://www.irct.ir/).

Abstract
Aluminum (Al) is an abundant metal with wide application in our daily lives including medicine, industry, cosmetics, and packaging. After entrance to the body, aluminum binds to transferrin and reaches different tissues. Al is a metalloestrogen that can lead to oxidative stress (OxS) and endocrine disruption. No detailed study can be found addressing the effect of Al on the ovary and granulosa cells (GCs). In this study, the focus is on the treated ovaries and GCs of NMRI mice exposed to low, middle, and high doses of aluminum chloride (AlCl3) via in vitro and in vivo assays. The steroidogenic, proliferative, apoptotic, and autophagic-related genes were examined. Up-regulated expression of steroidogenic and proliferative genes was detected. The observed apoptotic and autophagic genes had variable expression. Interrupted ovarian structure, disrupted folliculogenesis, presence of Call-Exner bodies, overexpression of steroidogenic gene, and unbalanced apoptosis/autophagy and proliferation resembled features of granulosa cell tumor (GCT).

Abstract
Aluminium, a substance found in large amounts in nature, has been widely used for various purposes, especially food additives. The effects of long-term and excessive exposure to aluminium on human health are receiving increasing attention. The extensive human use of aluminium food additives can also cause aluminium to enter the ecosystem, where it has significant impacts on insects. This study explored the cytotoxicity and changes in gene expression under aluminium potassium sulfate toward Spodoptera frugiperda 9 cells. We found that high concentrations of aluminium resulted in cell enlargement and cell membrane breakage, decreased cell vitality, and apoptosis. Through RNA-Seq transcriptomics, we found that aluminium ions may inhibit the expression of regulatory-associated protein of mTOR, tdIns-dependent protein kinase-1, and small heat shock proteins (heat shock 70 kDa protein and crystallin alpha B), leading to changes in mTOR-related pathways (such as the longevity regulation pathway and PI3K-Akt signalling pathway), and promoting cell apoptosis. On the other hand, aluminium ions lead to the overexpression of GSH S-transferase, prostaglandin-H2 D-isomerase and pyrimidodiazepine synthase, and induce intracellular oxidative damage, which ultimately affects cell growth and apoptosis through a series of cascade reactions.

Abstract
Selenium is closely related to the occurrence of heart disease, and an appropriate amount of selenium can alleviate inflammatory changes caused by various factors. Lipopolysaccharide (LPS), as a specific component of the cell wall of Gram-negative bacteria, is often used to construct various inflammatory models. In order to explore the effect of selenium on LPS-induced myocardial inflammation in chickens, we chose 4-month-old laying hens to be fed with a selenium-rich diet containing 0.5 g kg-1 Se, and injected LPS into the abdominal cavity at the age of 8 months to establish an inflammation model. We observed the myocardial tissue lesions by light microscopy, and detected miR-128-3p, p38MAPK, and NF-κB pathway-associated inflammatory factors and Th1/Th2 related factors by qRT-PCR and Western blot. The results showed that LPS stimulation inhibited miR-128-3p, which increased the expression of p38MAPK and NF-κB, while the expression of TNF-α, IL-1, PTGE, COX-2 and iNOS increased. Additionally, the expression of IL-4 and IL-6 increased and IFN-γ decreased, suggesting an imbalance of Th1/Th2. We also found that LPS treatment not only increased the content of H2O2 and MDA in the myocardium, but also increased the expression of HSP60, HSP70 and HSP90, while the activity of SOD, GPX and CAT and the content of GSH decreased. Interestingly, the addition of selenium can alleviate the changes in the above indicators. Finally, we concluded that selenium inhibits the occurrence of oxidative stress and ultimately alleviates myocardial inflammation induced by LPS through the miR-128-3p-p38MAPK-NF-κB pathway.
