Abstract
Coenzyme A (CoA) is an essential cofactor required for over a hundred metabolic reactions in the human body. This cofactor is synthesized de novo in our cells from vitamin B5, also known as pantothenic acid, a water-soluble vitamin abundantly present in vegetables and animal-based foods. Neurodegenerative disorders, cancer, and infectious diseases have been linked to defects in de novo CoA biosynthesis or reduced levels of this coenzyme. There is now accumulating evidence that CoA limitation is a critical pathomechanism in cardiac dysfunction too. In the current review, we will summarize our current knowledge on CoA and heart failure, with emphasis on two primary cardiomyopathies, phosphopantothenoylcysteine synthetase and phosphopantothenoylcysteine decarboxylase deficiency disorders biochemically characterized by a decreased level of CoA in patients' samples. Hence, we will discuss the potential benefits of CoA restoration in these diseases and, more generally, in heart failure, by vitamin B5 and its derivatives pantethine and 4'-phosphopantetheine.

Heliyon 2024; 10:e24007. [PMID: 38268590 PMCID: PMC10806266 DOI: 10.1016/j.heliyon.2024.e24007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 12/13/2023] [Accepted: 01/02/2024] [Indexed: 01/26/2024] Open
Abstract
Introduction Lipopolysaccharide (Lps) is an essential component responsible for the virulence of gram-negative bacteria. Lps can cause damage to many organs, including the heart, kidneys, and lungs. Dexpanthenol (Dex) is an agent that exhibits anti-oxidative and anti-inflammatory effects and stimulates epithelialization. In this study, we aimed to investigate the effects of Dex on Lps-induced cardiovascular toxicity. Methods Rats were divided into four groups: control, Lps (5 mg/kg, intraperitoneal), Dex (500 mg/kg, intraperitoneal), and Lps + Dex. The control group received saline intraperitoneally (i.p.) once daily for three days. The Lps group received saline i.p. once daily for three days and a single dose of Lps i.p. was administered on the third day. The Dex group received Dex i.p. once daily for three days and saline on the third day. The Lps + Dex group received Dex i.p. once daily for three days and a single dose of Lps i.p. on the third day. Heart and aortic tissues were taken for biochemical, histopathological, immunohistochemical, and genetic analysis. Results Lps injection caused histopathological changes in both heart and aortic tissues and significantly increased total oxidant status and oxidative stress index levels. Interleukin-6, and Tumor necrosis factor-α mRNA expressions were significantly altered in heart and aorta, likely do to the anti-inflammatory and antioxidative effects of Dex. Furthermore, Dex affected Caspase-3 and Hypoxia-inducible factor 1-α staining patterns. Conclusions Our results show that Dex treatment has a protective effect on Lps-induced cardiac and endothelial damage in rats by reducing inflammation, oxidative stress, and apoptosis.

Abstract
Methotrexate is a familiar chemotherapeutic preferred in a wide range of clinical fields such as leukemia, psoriasis, rheumatoid arthritis, neoplastic and autoimmune disorders. However, methotrexate therapy has limitations as it causes severe side effects from which liver damage is the most important one. Several antioxidant compounds have been studied against methotrexate related liver toxicity, but dexpanthenol has not been experienced. Vitamin B5-derived dexpanthenol is a usual therapeutic having a potent anti-inflammatory and antioxidant effect. In this study, we aimed to evaluate the ameliorating effect of dexpanthenol against methotrexate-induced hepatotoxicity. We performed our experiments on Wistar albino rats divided randomly into four groups involving control, dexphantenol, dexpanthenol + methotrexate and methotrexate applied animals. After this experimental work on rats, for the first time, we showed dexpanthenol improvement effect on ROS-caused hepatotoxicity initiated by methotrexate administration in terms of liver tissue antioxidant/oxidant enzymes, liver function tests, and histological changes. We suggest that dexpanthenol might be applied during methotrexate treatment in order to reduce the liver toxicity. However, further studies are needed to find out the optimal dose regimen and to understand the mechanism of action.

[PMID: 37727368 PMCID: PMC10506875 DOI: 10.1155/2023/5536933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 08/25/2023] [Accepted: 09/01/2023] [Indexed: 09/21/2023] Open
Abstract
Background Cytokine storm syndrome (CSS) is a major cause of morbidity and mortality in people suffering from hyperinflammatory status, which diverse etiological factors, including pathogens, therapeutic interventions, malignancies, and autoimmune disorders, can instigate. Since there is limited research on the antioxidant properties of fraxin and no studies have investigated its potential as an anticytokine storm agent, it is important to note that most studies have primarily focused on proinflammatory cytokines such as IL-1β, IL-6, and TNFα during cytokine storm. However, little research discusses the role of chemokines, particularly IL-8, during cytokine storms. Therefore, further investigation is warranted into the role of fraxin as an anticytokine storm agent and the involvement of IL-8 in cytokine storms. The present study examines the preventive efficacy of fraxin and the combination of fraxin and dexamethasone (FD) in mitigating lipopolysaccharide-induced systemic inflammation in mice caused by Escherichia coli, 055: B5. Methods Five groups of ten mice were randomly assigned: LPS only group (5 mg/kg, intraperitoneally i.p.), control (normal saline N.S. 1 ml/kg, i.p.), concentrations were selected based on previous literature, fraxin (120 mg/kg, i.p.), dexamethasone (5 mg/kg, i.p.), fraxin + dexamethasone (FD) (60 mg/kg + 2.5 mg/kg, i.p.), administered one hour before LPS injection (5 mg/kg,i.p.), animals were euthanized next day, and interleukin-8 (IL-8) was quantified in serum using an enzyme-linked immunosorbent assay. The liver and heart tissues underwent histopathological analysis to assess morphological changes. For data analysis using ANOVA and Tukey post hoc tests, the Kruskal-Wallis and Mann-Whitney U tests were employed to analyze the histological results. Results A significant decline in IL-8 levels was recorded in the treatment groups almost to the same degree (p < 0.001), and the percentage of inhibition of IL-8 for fraxin, dexamethasone, and FD was 93%.92.4%, and 93%, respectively, compared to the LPS-only group. Histopathological scores were significantly reduced in liver and heart tissue (P < 0.05). Conclusions All interventions used in this study significantly reduced interleukin-8 (IL-8) levels and reduced LPS-induced liver and cardiac damage. The combination (FD) did not result in an evident superiority of either agent. More research is required to identify the possible usefulness of these agents in treating hyperinflammatory diseases, such as cytokine storms, in future clinical practice.

Abstract
Doxorubicin (DOX), which is used as a chemotherapeutic agent in the treatment of tumors, has limited use due to its toxicity in various organs and tissues. One of the organs where DOX has a toxic effect is the lung. DOX shows this effect by increasing oxidative stress, inflammation, and apoptosis. Dexpanthenol (DEX), a homologue of pantothenic acid, has anti-inflammatory, antioxidant, and anti-apoptotic properties. Therefore, the purpose of our investigation was to explore how DEX could counteract the harmful effects of DOX on the lungs. Thirty-two rats were used in the study, and 4 groups were formed (control, DOX, DOX + DEX, and DEX). In these groups, parameters of inflammation, ER stress, apoptosis, and oxidative stress were evaluated by immunohistochemistry, RT-qPCR, and spectrophotometric methods. In addition, lung tissue was evaluated histopathologically in the groups. While CHOP/GADD153, caspase-12, caspase-9, and Bax gene expressions increased in the DOX group, Bcl-2 gene expression levels significantly decreased. In addition, changes in Bax and Bcl-2 were supported immunohistochemically. There was a significant increase in oxidative stress parameters and a significant decrease in antioxidant levels. In addition, an increase in inflammatory marker (TNF-α and IL-10) levels was determined. There was a decrease in CHOP/GADD153, caspase-12, caspase-9, and Bax gene expressions and an increase in Bcl-2 gene expression in the DEX-treated group. In addition, it was determined that there was a decrease in oxidative stress levels and inflammatory findings. The curative effect of DEX was supported by histopathological findings. As a result, it was experimentally determined that DEX has a healing effect on oxidative stress, ER stress, inflammation, and apoptosis in lung damage caused by DOX toxicity.

Abstract
BACKGROUND There are few data on caspase‑9 (intrinsic apoptosis pathway initiating caspase) in septic patients. Higher serum caspase‑9 levels in septic patients than in healthy subjects have been found. However, there are no data on the prognosis of septic patients and blood caspase‑9 concentrations. Therefore, the objective of this study was to analyze the potential association between blood caspase‑9 concentrations and prognosis in septic patients. METHODS Three Spanish hospitals participated in the recruitment of septic patients admitted to intensive care units in this observational and prospective study. Serum caspase‑9 concentrations were determined at the time of sepsis diagnosis. The 30-day mortality was the outcome variable. RESULTS Higher Acute Phisiology and Chronic Health Evaluation(APACHE)-II (p < 0.001), Sepsis-related Organ Failure Assessment score (SOFA) (p < 0.001), serum lactic acid levels (p = 0.001), serum caspase‑9 levels (p < 0.001), age (p < 0.001), International normalized ratio (INR) (p = 0.001), rate of septic shock (p = 0.001), Activated partial thromboplastin time (aPTT) (p = 0.03), rate of diabetes mellitus (p = 0.04), and lower platelet counts (p = 0.01) were found in non-surviving (n = 80) than in surviving patients (n = 134). Multiple logistic regression analysis showed an association between serum caspase‑9 concentrations and mortality (Odds Ratio (OR) = 1.985; 95% Confidence Interval (CI) = 1.359-2.900; p < 0.001) regardless of age, SOFA, lactic acid and septic shock and history of diabetes mellitus. No significant differences were found when we compared area under ROC curves of serum caspase‑9 with SOFA (p = 0.92) and with lactic acid (p = 0.59). CONCLUSIONS The main novel finding of our study was the association between blood caspase‑9 concentrations and septic patient prognosis. However, our study showed some limitations (for example, the absence of data in respect to execution of Surviving Sepsis Campaign bundles); thus, more research could be interesting to confirm our preliminary findings.

Abstract
PURPOSE Sepsis is characterized by an acute inflammatory response to infection, often with multiple organ failures, especially severe lung injury. This study was implemented to probe circular RNA (circRNA) protein tyrosine kinase 2 (circPTK2)-associated regulatory mechanisms in septic acute lung injury (ALI). METHODS A cecal ligation and puncture-based mouse model and an lipopolysaccharides (LPS)-based alveolar type II cell (RLE-6TN) model were generated to mimic sepsis. In the two models, inflammation- and pyroptosis-related genes were measured. RESULTS The degree of lung injury in mice was analyzed by hematoxylin and eosin (H&E) staining and the apoptosis was by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling staining. In addition, pyroptosis and toxicity were detected in cells. Finally, the binding relationship between circPTK2, miR-766, and eukaryotic initiation factor 5A (eIF5A) was detected. Data indicated that circPTK2 and eIF5A were up-regulated and miR-766 was down-regulated in LPS-treated RLE-6TN cells and lung tissue of septic mice. Lung injury in septic mice was ameliorated after inhibition of circPTK2. CONCLUSIONS It was confirmed in the cell model that knockdown of circPTK2 effectively ameliorated LPS-induced ATP efflux, pyroptosis, and inflammation. Mechanistically, circPTK2 mediated eIF5A expression by competitively adsorbing miR-766. Taken together, circPTK2/miR-766/eIF5A axis ameliorates septic ALI, developing a novel therapeutic target for the disease.

Abstract
OBJECTIVE Dexpanthenol (DXP) reportedly protects tissues against oxidative damage in various inflammation models. This study aimed to evaluate its effects on oxidative stress, inflammation, apoptosis, and neurological recovery in an experimental rabbit spinal cord ischemia/reperfusion injury (SCIRI) model. METHODS Rabbits were randomized into 5 groups of 8 animals each: group 1 (control), group 2 (ischemia), group 3 (vehicle), group 4 (methylprednisolone, 30 mg/kg), and group 5 (DXP, 500 mg/kg). The control group underwent laparotomy only, whereas other groups were subjected to spinal cord ischemia by aortic occlusion (just caudal to the 2 renal arteries) for 20 min. After 24 h, a modified Tarlov scale was employed to record neurological examination results. Malondialdehyde and caspase-3 levels and catalase and myeloperoxidase activities were analyzed in tissue and serum samples. Xanthine oxidase activity was measured in the serum. Histopathological and ultrastructural evaluations were also performed in the spinal cord. RESULTS After SCIRI, serum and tissue malondialdehyde and caspase-3 levels and myeloperoxidase and serum xanthine oxidase activities were increased (P < 0.05-0.001). However, serum and tissue catalase activity decreased significantly (P < 0.001). DXP treatment was associated with lower malondialdehyde and caspase-3 levels and reduced myeloperoxidase and xanthine oxidase activities but increased catalase activity (P < 0.05-0.001). Furthermore, DXP was associated with better histopathological, ultrastructural, and neurological outcome scores. CONCLUSIONS This study was the first to evaluate antioxidant, anti-inflammatory, antiapoptotic, and neuroprotective effects of DXP on SCIRI. Further experimental and clinical investigations are warranted to confirm that DXP can be administered to treat SCIRI.

Abstract
Sepsis is capable of causing systemic infections resulting in multiple organ damage. Dexpanthenol (DXP) has been reported to protect against kidney and liver injury. Therefore, this paper attempts to explore the role of DXP in sepsis-induced kidney and liver injury. A mice model of sepsis was established using the cecal ligation and puncture (CLP) method. The expressions of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6 and monocyte chemoattractant protein (MCP)-1 in the serum of mice were measured utilizing enzyme linked immunosorbent assay (ELISA). Additionally, the damage of kidney and liver tissues in CLP-induced mice was determined by their respective commercial kits, western blot, and hematoxylin–eosin (HE) staining kits. The apoptosis of kidney and liver tissues in CLP-induced mice was assessed by means of terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and western blot. It was observed that DXP decreased the expressions of TNF-α, IL-1β, IL-6, and MCP-1 in the serum of CLP-induced mice, attenuated the functional impairment, pathological damage, inflammation, and cell apoptosis of kidney tissue. Meanwhile, DXP decreased the functional impairment of liver in CLP-induced mice, reduced the levels of inflammatory factors and antioxidant enzymes, attenuated liver pathological damage, and decreased cell apoptosis in liver tissues. In conclusion, DXP attenuates inflammatory damage and apoptosis in kidney and liver organs in a sepsis model.

Abstract
Sepsis was characterized via an acute inflammatory response to infection, often accompanying by multiple organ failure, particularly lung damage. Circular RNA (circRNA) played an important role in the pathology of a variety of diseases. However, the role of circRNA in sepsis-induced lung injury (LI) remained unknown. This study was to explore the expression and role of circVMA21 in sepsis LI and the possible molecular mechanism. The results manifested circVMA21 and CD2-associated protein (CD2AP) were down-regulated in lung tissue and lipopolysaccharide (LPS)-treated BEAS-2B, while microRNA (miR)-497-5p was up-regulated. A large number of deaths in rats after surgery of 72 h were caused via cecal ligation-perforation surgery, W/D value and Bax positive cells were increased, LI was caused, cell apoptosis, tumor necrosis factor-α, Interleukin (IL)-1β and IL-6 expression were promoted and Bcl-2 positive cells were decreased. Overexpression of circVMA21 ameliorated these phenomena. In addition, LPS-induced apoptosis and inflammation of BEAS-2B cells was improved via overexpression of circVMA21, while overexpression of miR-497-5P was opposite. Apoptosis, inflammation, and oxidative damage of BEAS-2B cells were aggravated via knockdown of circVMA21, but it was reversed by knockdown of miR-497-5p or overexpression of CD2AP. Mechanistically, CircVMA21 mediated CD2AP expression through competitive adsorption of miR-497-5p. In conclusion, this work showed circVMA21 improved LI in sepsis rats by targeting miR-497-5p/CD2AP axis, suggesting that circVMA21 may be a novel therapeutic target for sepsis-induced LI.

Abstract
Heart failure (HF) is a plague of the aging population in industrialized countries that continues to cause many deaths despite intensive research into more effective treatments. Although the therapeutic arsenal to face heart failure has been expanding, the relatively short life expectancy of HF patients is pushing towards novel therapeutic strategies. Heart failure is associated with drastic metabolic disorders, including severe myocardial mitochondrial dysfunction and systemic nutrient deprivation secondary to severe cardiac dysfunction. To date, no effective therapy has been developed to restore the cardiac energy metabolism of the failing myocardium, mainly due to the metabolic complexity and intertwining of the involved processes. Recent years have witnessed a growing scientific interest in natural molecules that play a pivotal role in energy metabolism with promising therapeutic effects against heart failure. Among these molecules, B vitamins are a class of water soluble vitamins that are directly involved in energy metabolism and are of particular interest since they are intimately linked to energy metabolism and HF patients are often B vitamin deficient. This review aims at assessing the value of B vitamin supplementation in the treatment of heart failure.

The protective role of fosfomycin in lung injury due to oxidative stress and inflammation caused by sepsis. Life Sci 2021; 279:119662. [PMID: 34081989 DOI: 10.1016/j.lfs.2021.119662] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Revised: 05/02/2021] [Accepted: 05/24/2021] [Indexed: 11/22/2022]
Abstract
AIM Early and prompt treatment of sepsis by effective antibiotics against susceptible organisms may be lifesaving. However, increased antibiotic resistance and side effects of chemotherapeutic agents limiting their tolerability result in a restricted use of medications. This has led to an increased search for solution oriented novel treatments and therapeutic targets, as well as investigations on the pathogenesis and physiology of sepsis. In this study, we aimed to examine the antioxidant and anti-inflammatory effects of fosfomycin in sepsis resulting from other causes. MAIN METHODS Sprague Dawley rats were assigned into three groups. Randomly selected control rats received intraperitoneal saline solution only. Only caecal puncture and ligation were carried out in the caecal ligation and puncture (CLP) group, while in the CLP + fosfomycin group (CLP + FOS), together with sepsis due to caecal puncture and ligation, 500 mg/kg of FOS was administered intraperitoneally (i.p.). KEY FINDINGS As compared to the control group, elevated TBARS and TNF-α levels as well as increased expression of NF-kB/p65 and TLR-4 and reduced -SH levels were found in the lung tissue of CLP rats. On the other hand, TBARS and TNF-α levels were reduced and NF-kB/p65 and TLR-4 expressions were decreased together with increase in total -SH levels among CLP + FOS (500 mg/kg i.p.) rats. SIGNIFICANCE FOS treatment may represent a promising agent in terms of reducing the sepsis-related lung injury due to its antimicrobial effects as well as its antioxidant and anti-inflammatory properties.
