Abstract
Nonenzymatic glycation of proteins is accelerated in the context of elevated blood sugar levels in diabetes. Vitamin and mineral deficiencies are strongly linked to the onset and progression of diabetes. The antiglycation ability of various water- and fat-soluble vitamins, along with trace minerals like molybdenum (Mo), manganese (Mn), magnesium (Mg), chromium, etc., have been screened using Bovine Serum Albumin (BSA) as in vitro model. BSA was incubated with methylglyoxal (MGO) at 37 °C for 48 h, along with minerals and vitamins separately, along with controls and aminoguanidine (AG) as a standard to compare the efficacy of the minerals and vitamins. Further, their effects on renal cells' (HEK-293) antioxidant potential were examined. Antiglycation potential is measured by monitoring protein glycation markers, structural and functional modifications. Some minerals, Mo, Mn, and Mg, demonstrated comparable inhibition of protein-bound carbonyl content and ß-amyloid aggregation at maximal physiological concentrations. Mo and Mg protected the thiol group and free amino acids and preserved the antioxidant potential. Vitamin E, D, B1 and B3 revealed significant glycation inhibition and improved antioxidant potential in HEK-293 cells as assessed by estimating lipid peroxidation, SOD and glyoxalase activity. These results emphasize the glycation inhibitory potential of vitamins and minerals, indicating the use of these micronutrients in the prospect of the therapeutic outlook for diabetes management.

Vitamin E (α-Tocopherol) Does Not Ameliorate the Toxic Effect of Bisphenol S on the Metabolic Analytes and Pancreas Histoarchitecture of Diabetic Rats. TOXICS 2023; 11:626.

Abstract
This study investigated whether the coadministration of vitamin E (VitE) diminishes the harmful effects provoked by plasticizer bisphenol S (BPS) in the serum metabolites related to hepatic and renal metabolism, as well as the endocrine pancreatic function in diabetic male Wistar rats. Rats were divided into five groups (n = 5-6); the first group was healthy rats (Ctrl group). The other four groups were diabetic rats induced with 45 mg/kg bw of streptozotocin: Ctrl-D (diabetic control); VitE-D (100 mg/kg bw/d of VitE); BPS-D (100 mg/kg bw/d of BPS); The animals from the VitE + BPS-D group were administered 100 mg/kg bw/d of VitE + 100 mg/kg bw/d of BPS. All compounds were administered orally for 30 days. Body weight, biochemical assays, urinalysis, glucose tolerance test, pancreas histopathology, proximate chemical analysis in feces, and the activity of antioxidants in rat serum were assessed. The coadministration of VitE + BPS produced weight losses, increases in 14 serum analytes, and degeneration in the pancreas. Therefore, the VitE + BPS coadministration did not have a protective effect versus the harmful impact of BPS or the diabetic metabolic state; on the contrary, it partially aggravated the damage produced by the BPS. VitE is likely to have an additive effect on the toxicity of BPS.

Design and Investigation of New Water-Soluble Forms of α-Tocopherol with Antioxidant and Antiglycation Activity Using Amphiphilic Copolymers of N-Vinylpyrrolidone. Pharmaceutics 2023; 15:pharmaceutics15051388. [PMID: 37242630 DOI: 10.3390/pharmaceutics15051388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 04/26/2023] [Accepted: 04/28/2023] [Indexed: 05/28/2023] Open
Abstract
Water-soluble forms of α-tocopherol (TP) as an effective antioxidant were obtained by encapsulating it into nanoparticles (NPs) of amphiphilic copolymers of N-vinylpyrrolidone with triethylene glycol dimethacrylate (CPL1-TP) and N-vinylpyrrolidone with hexyl methacrylate and triethylene glycol dimethacrylate (CPL2-TP) synthesized by radical copolymerization in toluene. The hydrodynamic radii of NPs loaded with TP (3.7 wt% per copolymers) were typically ca. 50 or 80 nm depending on copolymer composition, media, and temperature. Characterization of NPs was accomplished by transmission electron microscopy (TEM), IR-, and 1H NMR spectroscopy. Quantum chemical modeling showed that TP molecules are capable to form hydrogen bonds with donor groups of the copolymer units. High antioxidant activity of both obtained forms of TP has been found by the thiobarbituric acid reactive species and chemiluminescence assays. CPL1-TP and CPL2-TP effectively inhibited the process of spontaneous lipid peroxidation as well as α-tocopherol itself. The IC50 values of luminol chemiluminescence inhibition were determined. Antiglycation activity against vesperlysine and pentosidine-like AGEs of TP water-soluble forms was shown. The developed NPs of TP are promising as materials with antioxidant and antiglycation activity and can be used in various biomedical applications.

Abstract
Diabetes mellitus is a common metabolic disorder associated with chronic complications including a state of mild to moderate cognitive impairment, in particular psychomotor slowing and reduced mental flexibility, not attributable to other causes, and shares many symptoms that are best described as accelerated brain ageing. A common theory for aging and for the pathogenesis of this cerebral dysfunctioning in diabetes relates cell death to oxidative stress in strong association to inflammation, and in fact nuclear factor κB (NFκB), a master regulator of inflammation and also a sensor of oxidative stress, has a strategic position at the crossroad between oxidative stress and inflammation. Moreover, metabolic inflammation is, in turn, related to the induction of various intracellular stresses such as mitochondrial oxidative stress, endoplasmic reticulum (ER) stress, and autophagy defect. In parallel, blockade of autophagy can relate to proinflammatory signaling via oxidative stress pathway and NFκB-mediated inflammation.

Abstract
Diabetes is a disease characterized by poor glycemic control for which risk of the type 2 form increases with age. A rise in blood glucose concentration causes increased oxidative stress which contributes to the development and progression of diabetes-associated complications. Studies have shown that primary antioxidants or genetic manipulation of antioxidant defenses can at least partially ameliorate this oxidative stress and consequentially, reduce severity of diabetic complications in animal models. Data from humans is less clear and will be summarized in this review. We highlight results from studies performed to investigate the role of vitamin E in preventing diabetes-induced oxidative damage in cell culture, animal models, and human participants, and summarize evidence testing whether this nutrient has an effect on outcomes related to the diabetic complications of nephropathy, retinopathy, and neuropathy. The most compelling evidence for an effect of vitamin E in diabetes is on protection against lipid peroxidation, whereas effects on protein and DNA oxidation are less pronounced. More studies are required to make definitive conclusions about the effect of vitamin E treatment on diabetes complications in human subjects.

Abstract
This review will focus on the impact of hyperglycemia-induced oxidative stress in the development of diabetes-related neural dysfunction. Oxidative stress occurs when the balance between the production of reactive oxygen species (ROS) and the ability of cells or tissues to detoxify the free radicals produced during metabolic activity is tilted in the favor of the former. Although hyperglycemia plays a key role in inducing oxidative stress in the diabetic nerve, the contribution of other factors, such as endoneurial hypoxia, transition metal imbalances, and hyperlipidemia have been also suggested. The possible sources for the overproduction of ROS in diabetes are widespread and include enzymatic pathways, auto-oxidation of glucose, and mitochondrial superoxide production. Increase in oxidative stress has clearly been shown to contribute to the pathology of neural and vascular dysfunction in diabetes. Potential therapies for preventing increased oxidative stress in diabetic nerve dysfunction will be discussed.

Abstract
BACKGROUND alpha-Lipoic acid is a potent antioxidant that improves renal function in diabetes by lowering glycemia, however, the mechanisms by which alpha-lipoic acid exerts its antioxidant effects are not completely understood. METHODS Metabolic parameters, renal function, and morphology, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity and subunit expression were analyzed in nondiabetic and streptozotocin-induced diabetic rats fed normal rat chow (control) with or without alpha-lipoic acid (30 mg/kg body weight) for 12 weeks. RESULTS Blood glucose was increased with diabetes (nondiabetic + control 89 +/- 3 mg/dL and diabetic + control 336 +/- 28 mg/dL) and was similar with alpha-lipoic acid treatment (diabetic +alpha-lipoic acid 351 +/- 14 mg/dL). In contrast, alpha-lipoic acid attenuated albuminuria (nondiabetic + control 8.9 +/- 1.3 mg/day; diabetic + control 28.1 +/- 4.6 mg/day; and diabetic +alpha-lipoic acid 17.8 +/- 1.2 mg/day) associated with diabetes. Similarly, alpha-lipoic acid attenuated glomerulosclerosis (nondiabetic + control 0.22 +/- 0.01; diabetic + control 0.55 +/- 0.04; diabetic +alpha-lipoic acid 0.36 +/- 0.03), tubulointerstitial fibrosis (nondiabetic + control 0.42 +/- 0.18; diabetic + control 1.52 +/- 0.05; diabetic +alpha-lipoic acid 1.10 +/- 0.05), superoxide anion (O(.-) (2)) generation (nondiabetic +control 15.8 +/- 1.7; diabetic +control 87.1 +/- 3.5; diabetic +alpha-lipoic acid 25.5 +/- 3.3 RLU/mg protein), and urine 8-isoprostane (8-iso) excretion (nondiabetic + control 7.4 +/- 1.4; diabetic + control 26.0 +/- 4.5; diabetic +alpha-lipoic acid 19.6 +/- 5.6 ng/day) associated with diabetes. alpha-Lipoic acid also reduced kidney expression of NADPH oxidase subunits p22phox and p47phox. Surprisingly, alpha-lipoic acid appears to cause pro-oxidant effects in nondiabetic animals, resulting in increased albuminuria (nondiabetic +alpha-lipoic acid 14.2 +/- 1.2 mg/day), increase in plasma creatinine levels (nondiabetic + control 59 +/- 6; diabetic + control 68 +/- 6; nondiabetic +alpha-lipoic acid 86 +/- 9; diabetic +alpha-lipoic acid 69 +/- 7 mumol/L), exacerbated glomerulosclerosis and tubulointerstitial fibrosis, increased O(.-) (2) generation, up-regulated p22phox and p47phox expression and increased 8-iso excretion. CONCLUSION We conclude that alpha-lipoic acid improves albuminuria and pathology in diabetes by reducing oxidative stress, while in healthy animals, alpha-lipoic acid may act as a pro-oxidant, contributing to renal dysfunction.

Abstract
In the present study we investigated the effects of a long-term treatment with vitamin E, an antioxidant vitamin, insulin or their combination on cataracts of streptozotocin (STZ)-induced diabetic rats fed a high cholesterol diet. Each rat was checked for cataracts at 0, 1, 2, 4, 8, 12 and 15 weeks after STZ injection. Cataracts were observed from 8 weeks in the control diabetic rats and their incidence of catarats increased to 100% by 12 weeks. The incidence of cataracts in rats treated with vitamin E, insulin and their combination was first seen at 12 weeks and 56%, 20% and 10%, respectively, at 12 weeks and 78%, 50% and 20%, respectively, at 15 weeks. The preventive effects of either agent alone and their combination on the cataracts were in agreement with those obtained by histopathological evaluation of eyeballs. The combined treatment with both agents markedly improved hyperglycemia, hyperlipidemia and increased serum lipid peroxide levels. These results indicate that the combined treatment with vitamin E and insulin is useful in preventing the development and progression of diabetic cataracts.

Abstract
In the present study, we investigated the effects of a long-term treatment with vitamin E, an antioxidant vitamin, insulin, or their combination on renal damage in streptozotocin (STZ)-induced diabetic rats fed a high cholesterol diet. Increases in urinary albumin and lipid peroxide (LPO) excretions were observed in these diabetic rats, when both urinary parameters were measured at 8 and 15 weeks after STZ administration. Daily treatment with vitamin E, insulin, or their combination markedly suppressed the increase in the 24 h urinary albumin and lipid peroxide excretions. Furthermore, glycogen degeneration of distal tubules, fatty degeneration of glomerular endothelium and hypertrophy of glomeruli and mesangium were observed in the kidneys of the diabetic animals when histopathological evaluation was performed at 4, 8, and 15 weeks (glomerular and mesangial hypertrophy were observed only at 15 weeks). Combined vitamin E and insulin treatment was the most effective at suppressing these renal histopathological changes. These results indicate that combined vitamin E and insulin treatment additively prevents the development and progression of renal damage in diabetic rats. Possible mechanisms for the preventive effect of this combined treatment are discussed.

Abstract
Oxidative stress results from a cell or tissue failing to detoxify the free radicals that are produced during metabolic activity. Diabetes is characterized by chronic hyperglycemia that produces dysregulation of cellular metabolism. This review explores the concept that diabetes overloads glucose metabolic pathways, resulting in excess free radical production and oxidative stress. Evidence is presented to support the idea that both chronic and acute hyperglycemia cause oxidative stress in the peripheral nervous system that can promote the development of diabetic neuropathy. Proteins that are damaged by oxidative stress have decreased biological activity leading to loss of energy metabolism, cell signaling, transport, and, ultimately, to cell death. Examination of the data from animal and cell culture models of diabetes, as well as clinical trials of antioxidants, strongly implicates hyperglycemia-induced oxidative stress in diabetic neuropathy. We conclude that striving for superior antioxidative therapies remains essential for the prevention of neuropathy in diabetic patients.
