Abstract Objective: Diabetic nephropathy (DN) is a deleterious microangiopathy of diabetes, constituting a critical determinant of fatality in diabetic patients. This work is purposed to disclose the effects and modulatory mechanism of BTG anti-proliferation factor 2 (BTG2) during the pathological process of DN. Methods: BTG2 expression in kidney tissues of diabetic mice and high glucose (HG)-exposed human proximal tubular cell line HK-2 was assessed with Western blot and RT-qPCR. The diabetic mice model was constructed by streptozotocin injection and confirmed by the blood glucose level beyond 16.7 mmol/L. Hematoxylin and eosin (H&E) staining and measurement of… More >

Abstract In China, Parkinson’s disease (PD) is the second most prevalent central nervous system (CNS) degenerative illness affecting middle-aged and older persons. Movement disorders including resting tremor, bradykinesia, myotonia, postural instability, and gait instability are the predominant clinical symptoms. The two main types of PD are sporadic and familial, with sporadic PD being the more prevalent of the two. The environment, genetics, mitochondrial dysfunction, oxidative stress, inflammation, protein aggregation and misfolding, loss of trophic factors, cell death, and gut microbiota may all have a role in the etiology of PD. PD is inversely connected with other More >

Abstract Background: Diabetes retinopathy (DR) is a complication of diabetes that affects patients’ vision. Previous studies have found blueberry anthocyanins extract (BAE) can inhibit the progression of DR, but its mechanism is not completely clear. Methods: To study the role of BAE in diabetes retinopathy, we treated human retinal endothelial cells (HRCECs) with 30 mM high glucose to simulate the microenvironment of diabetes retinopathy and used BAE to intervene the in vitro high glucose-induced retinopathy model. HRCEC cell viability and apoptosis rates were examined by Cell Counting Kit 8 (CCK-8) assay and flow cytometry assay. The binding… More >

Abstract Introduction: Human chemerin is an adipokine that regulates chemotaxis, inflammation, and glucose metabolism. In addition, accumulating evidence suggests that chemerin promotes apoptosis, autophagy, and pyroptosis. However, there are no data on its impact on eryptosis. The current study aimed to analyze the effects of human active Glu-Ser chemerin on eryptosis in vitro. Materials and Methods: Human chemerin 0-2-10-50 µg/mL was incubated for 24 h with human erythrocytes (hematocrit 0.4%) obtained from eight healthy individuals. Flow cytometry-based determination of phospholipid scrambling, reactive oxygen species (ROS) production, and intracellular Ca levels was performed. To supplement data on ROS and Ca… More >

Abstract Venom snake-derived peptides have multiple biochemical, pharmacological, and toxicological profiles, allowing for the discovery of new medicinal products and therapeutic applications. This review specifically examines the fundamental elements of neuroprotection offered by different oligopeptides derived from snake venom. It also includes a brief evaluation of short peptides that are being considered as potential therapeutic agents. Proline-rich peptides and tryptophyllin family peptides isolated from the crude venom of Viperidae family snakes, specifically Bothrops atrox, Bothrops jararaca, and Bothrops moojeni, have been shown to have pro-survival properties, the ability to reduce oxidative stress, and the ability to promote cell viability More >

Abstract Introduction: Dexamethasone (Dex) caused impaired osteoblast differentiation and oxidative stress (OS) in bone marrow mesenchymal stem cells (BMSCs). This work sought to elucidate the precise molecular pathway through which Dex influences osteogenic differentiation (OD) and OS in BMSCs. Methods: The expression of Runt-related transcription factor 1 (RUNX1) and alpha-2 macroglobulin (A2M) was assessed in Dex-treated BMSCs using qRT-PCR and Western Blot. Following the functional rescue experiments, cell proliferation was determined by MTT assay, reactive oxygen species (ROS) expression by DCFH-DA fluorescent probe, lactate dehydrogenase (LDH), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (Gpx) expression… More >

Abstract Background: As a form of biological therapy, placenta-derived mesenchymal stem cells (PDMSCs) exhibit considerable promise in addressing the complex pathological processes of traumaticbrain injury (TBI) due to their multi-target and multi-pathway mode of action. Material & Methods: This study investigates the protective mechanisms and benefits of PDMSCs in mitigating the effects of controlled cortical impact (CCI) in rats and glutamate-induced oxidative stress injury in HT22 cells in vitro. Our primary objective is to provide evidence supporting the clinical application of PDMSCs. Results: In the in vivo arm of our investigation, we observed a swift elevation of matrix metalloproteinase-9… More > Graphic Abstract

Abstract

Aluminum (Al) toxicity is a considerable factor limiting crop yield and biomass in acidic soil. Tartary buckwheat growing in acidic soil may suffer from Al poisoning. Here, we investigated the influence of Al stress on the growth of tartary buckwheat seedling roots, and the alleviation of Al stress by silicon (Si), as has been demonstrated in many crops. Under Al stress, root growth (total root length, primary root length, root tips, root surface area, and root volume) was significantly inhibited, and Al and malondialdehyde (MDA) accumulated in the root tips. At the same time, catalase (CAT)

Abstract Oxidative stress (OS) is intimately associated with tumorigenesis and has been considered a potential therapeutic strategy. However, the OS-associated therapeutic target for esophageal squamous cell carcinoma (ESCC) remains unconfirmed. In our study, gene expression data of ESCC and clinical information from public databases were downloaded. Through LASSO-Cox regression analysis, a risk score (RS) signature map of prognosis was constructed and performed external verification with the GSE53625 cohort. The ESTIMATE, xCell, CIBERSORT, TIMER, and ImmuCellAI algorithms were employed to analyze infiltrating immune cells and generate an immune microenvironment (IM). Afterward, functional enrichment analysis clarified the underlying… More >

Abstract Background: Anisodine hydrobromide (AT3), an anti-cholinergic agent, could be delivered to the brain across the blood-brain barrier and has been used clinically for the treatment of cerebral ischemia/reperfusion injury. Endothelial dysfunction can be caused by hypoxia/reoxygenation (H/R) via oxidative stress and metabolic alterations. The present study investigated whether AT3 regulates the production of nitric oxide (NO) and reactive oxygen species (ROS), and the HIF-1α pathway via regulation of muscarinic acetylcholine receptors (mAChRs) in brain microvascular endothelial cells after H/R exposure. Methods: Under H/R conditions, hCMEC/D3 cerebral microvascular endothelial cells were treated with AT3. Specific inhibitors… More > Graphic Abstract
