Abstract
Cisplatin is a widely used chemotherapeutic agent for the treatment of various cancers. However, the clinical use of cisplatin is limited by its cardiotoxic side effects. The primary mechanisms implicated in this cardiotoxicity include mitochondrial dysfunction, oxidative stress, inflammation, and apoptotic. Numerous natural compounds (NCs) have been introduced as promising protective factors against cisplatin-mediated cardiac damage. The current review summarized the potential of various NCs as cardioprotective agents at the molecular levels. These compounds exhibited potent antioxidant and anti-inflammatory effects by interaction with the PI3K/AKT, AMPK, Nrf2, NF-κB, and NLRP3/caspase-1/GSDMD pathways. Generally, the modulation of these signaling pathways by NCs represents a promising strategy for improving the therapeutic index of cisplatin by reducing its cardiac side effects.

Abstract
Malignant glioma is the deadliest form of brain cancer. Zingerone (ZO), a polyphenolic compound found in ginger, offers pharmacological properties that make it a promising agent for containing the growth of glioma cells. The present study was conducted to understand the efficacy of ZO in containing the growth of C6 glioma cells. The study also assessed the prophylactic role of ZO on rat brain glioma induced by C6 cell lines by addressing its antioxidative action on biochemical, behavioral, and histoarchitectural indices. For dose optimization, the animals were pretreated with different doses of ZO for a period of 2 weeks before the inoculation of glioma cells (1 × 105 /10 µL phosphate-buffered saline) in the caudate region of rat brain and the treatment with ZO continued for 4 more weeks post implantation. In vitro studies were done to assess the radical scavenging activity of ZO and also to determine its effects on viability of C6 glioma cells at different concentrations. Glioma-bearing rats showed significant alterations in memory; exploratory and muscular activities which were appreciably improved upon simultaneous supplementation of ZO administered at a dose of 50 mg/kg body weight and were also visible even at a higher dose. Glioma-bearing rats revealed a significant increase in reactive oxygen species, protein carbonyl contents, and lipid peroxidation, but showed a significant decrease in reduced glutathione and antioxidative enzymes in the brain tissue. Interestingly, all the biochemical indices and altered brain histoarchitecture displaying cellular atypia and hyperplasia showed appreciable improvement when supplemented with ZO at a dose of 50 mg/kg body weight.

BinMowyna MN. Zingerone attenuates intestinal injury and colitis caused by a high-fat diet through Nrf2 signaling regulation. Saudi J Biol Sci 2023; 30:103775. [PMID: 37766888 PMCID: PMC10519856 DOI: 10.1016/j.sjbs.2023.103775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 07/31/2023] [Accepted: 08/05/2023] [Indexed: 09/29/2023] Open
Abstract
This study examined the protective effect of Zingerone against a high-fat diet (HFD)-induced intestinal damage. Control and HFD rats were treated with the vehicle or Zingerone (100 mg/kg, orally) (n = 8 rats/groups). An extra group, HFD + Zingerone + brusatol (an Nrf2 inhibitor). This study treatment lasted four weeks. Zingerone reduced the nuclear levels of NF-B p65 in control and HFD-fed rats while increasing SOD, CAT, GSH, levels of mRNA, cytoplasmic levels, and Nrf2 nuclear levels. Zingerone treatment attenuated the duodenal epithelial damage and maintained the mucosal barrier by reducing plasma FITC-DX and serum LPS in rats fed with HFD. Concomitantly, it lowered the duodenal MDA, TNF-α, IL-6, and IL-1β levels. These impacts included changes in body weight, duodenal lipid levels, and Keap-1 expression, a natural Nrf2 inhibitor. We concluded that Zingerone reduces HFD-induced duodenal injury. These findings support Zingerone's clinical applicability against various inflammatory diseases of the intestine.

Abstract
Zingerone is a flavor phytochemical present in ginger, a flowering plant belonging to the Zingiberaceae family used as a condiment and herbal remedy. It possesses anti-inflammatory, antioxidant, and anti-apoptotic properties and also exhibits protective effects against radiation, chemicals, biological toxins, and oxidative stress. The current comprehensive literature review was performed in order to assess the therapeutical and protective properties of zingerone against various chemical and natural toxins by considering the mechanisms of action. Extensive searches were performed on Scopus, Web of Science, PubMed, and Google Scholar databases. Zingerone lessens oxidative stress, inflammation, apoptosis, and oxidative DNA damage by increasing the activities of superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and glutathione peroxidase (GPX). It prevents alginate production, which increases the cell's susceptibility to macrophages, serum, and antibiotics and dramatically lowers the generation of proinflammatory cytokines brought on by lipopolysaccharide (LPS). Cytokine production, MAPK, and NF-κB activation are all inhibited dose-dependently by zingerone. Zingerone also reduces 8-OHdG over-expression in the liver tissue and the expression of NADPH oxidase 4 (NOX4), inflammatory cytokines (e.g., IFN-γ, IL-17, IL-6, COX-2, TNF-α, and iNOS mRNA level), decreases macrophage inflammatory protein cytokines and eliminates free radicals. It also suppresses matrix metalloproteinase-2 (MMP-2) and MMP-9 during tumor progression, showing its anti-angiogenic activity. Strong radioprotective properties of zingerone are demonstrated against radiation-induced toxicity. The authors hope this review gives researchers some insight into conducting novel clinical and preclinical studies on pharmaceutical applications and the efficiency of zingerone in cancer treatment, and drug adverse effects.

Abstract
Diabetes mellitus (DM) provokes reproductive impairments through endocrine disturbance, sperm deficits, and testicular oxidative inflammation. The study investigated the reproductive protective effects of resveratrol (RSV) against testicular oxidative inflammation, sperm/endocrine deficits, and insulin resistance in streptozotocin- (STZ-, 65 mg/kg) induced DM rat model. Male rats were randomly divided into 4 groups (
): control, DM, RSV (150 mg/kg bw, orally), and RSV+DM group (21 days). The nontreated DM rats showed marked decreases in serum insulin, reproductive hormones (T, LH, and FSH), and lipid profile levels compared to control. The homeostatic index of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI) were adversely modulated. Sperm count and motility were profoundly decreased, whereas sperm abnormality was significantly increased. The testicular activities of catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), and malondialdehyde (MDA) level, along with inflammatory cytokines (TNF-α, IL-6, IL-4, and IL-10) were significantly dysregulated. The DM induced histopathological lesions compared to control rats. Interestingly, the RSV administration to DM rats attenuated the altered reproductive parameters, restored antioxidant mechanism, and anti-inflammatory responses with improved insulin resistance. RSV could prevent DM-induced reproductive deficits and insulin resistance via modulating oxidative stress-mediated testicular inflammation in rats.

Abstract
Diabetes is the most prevalent disorder in the world characterized by uncontrolled high blood glucose levels and nephropathy is one of the chief complications allied with hyperglycemia. Vanillic acid; the main bioactive compound derived from natural sources such as vegetables, fruits and plants possesses various pharmacological activities such as antioxidant, anti-inflammatory and anti-proliferative. The current study was designed to investigate the antidiabetic and renoprotective effects of vanillic acid by its various pharmacological activities. Streptozotocin (50 mg/kg)/nicotinamide (110 mg/kg) was used to induce diabetes in rats. Oral administration of vanillic acid once daily for 6 weeks (25, 50 and 100 mg/kg) significantly reduced the hyperglycemia, increased liver enzymes and normalized lipid profile that was altered in diabetic rats. Moreover, vanillic acid attenuated the impaired renal function as evidenced by a reduction in serum creatinine, urea, uric acid and urinary microproteinuria levels with a concomitant increase in urinary creatinine clearance in the nephropathic rats. Diabetic rats showed a marked increase in thiobarbituric acid reactive substances (TBARS) and superoxide anion generation (SAG) along with decreased reduced glutathione (GSH) in the renal tissue which was ameliorated in the vanillic acid-treated rats. Histopathologically, vanillic acid treatment was associated with reduced damage with normalized structural changes in renal tissue. Furthermore, treatment groups showed the suppression of upregulation of nuclear factor (NF)-κB, tumor necrosis factor (TNF)-α, cyclo-oxygenase (COX)-2 and up-regulation of Nuclear factor-erythroid 2-related factor 2 (Nrf-2) in the renal tissue. In conclusion, vanillic acid's ameliorative impact on diabetic nephropathic rats may be attributed to its powerful free radical scavenging property, down-regulation of NF-κB, TNF-α, COX-2 and up-regulation of Nrf-2 proteins in renal tissue.

Abstract
Diabetes mellitus is an oxidative stress-related disease characterized by hyperglycemia and a variety of complications, including nephropathy. Vitamin D has variable functions extending beyond the calcium metabolism to prevent oxidative tissue damage. We aimed to investigate whether vitamin D supplements could enhance Glibenclamide's effectiveness in treating diabetes and minimize the risk of associated pathology. Wistar rats were divided into normal control (n = 10) and diabetic (n = 30), where animals received two low doses of Streptozotocin 30 mg/kg/BW intraperitoneally to develop diabetes. The diabetic rats were then randomly divided into three equal groups: untreated, treated with Glibenclamide (0.6 mg/kg), and treated with Glibenclamide and Vitamin D3 (500 IU/kg). After eight weeks, the animals were sacrificed, and blood samples and kidney tissues were collected to evaluate biochemical, anti-oxidant, and pro-inflammatory cytokine levels and histological and immunohistochemical changes. Diabetic animals had significantly increased fasting blood glucose, lipid profile, blood urea, serum creatinine, and Malondialdehyde levels, whereas serum insulin, albumin, and the anti-oxidant enzymes superoxide dismutase and catalase were significantly decreased compared to normal control (p < 0.01). Furthermore, some renal histological changes were observed together with significantly increased immunoreactivity of anti-p53, anti-TNF-α, and anti-IL-6 antibodies when compared to the normal control. All abnormal parameters improved significantly with Glibenclamide therapy (p < 0.01), but combination therapy with vitamin D produced a much better result. In conclusion, vitamin D supplementation along with anti-diabetic medication can help prevent or reduce the severity of diabetic nephropathy due to its potent antioxidant, anti-inflammatory, and anti-apoptotic properties.

Abstract
OBJECTIVES Literature findings have instituted the role of hyperglycemia-induced oxidative stress and inflammation in the pathogenesis of cognitive derangement in diabetes mellitus (DM). Hyperoside (HYP) is a flavanone glycoside reported to possess diverse pharmacological benefits such as antioxidant and anti-inflammatory properties. The study explored whether HYP could mitigate DM-induced cognitive dysfunction and further elucidate on potential molecular mechanism in rats. METHODS Streptozotocin/high-fat diet-induced diabetic rats were treated orally with HYP (50, 200 and 400 mg/kg/day) for six consecutive weeks. The blood glucose and serum insulin levels, Morris water maze test, intraperitoneal glucose tolerance test, and brain acetylcholinesterase (AChE) activity were determined. The brain expression of inflammatory nuclear factor-kappa B (NF-κB), tumour necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6), as well as superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH), total antioxidant capacity (TAC), malondialdehyde (MDA), lipid profile and caspase-3 activity were estimated. RESULTS DM evoked hyperlipidemia, hypoinsulinemia, cognitive dysfunction by markedly increased AChE and reduction in learning and memory capacity. Brain activities of SOD and CAT, and levels of TAC and GSH were considerably depressed, whereas levels of IL-1β, IL-6, TNF-α, NF-κB, caspase-3 and MDA were prominently increased. Interestingly, the HYP treatment dose-dependently abrogated the altered cognitive and biochemical parameters. DISCUSSION The results suggested that hyperoside prevents DM-induced cognitive dysfunction, neuroinflammation and oxidative stress via antioxidant, anti-inflammatory and antiapoptotic mechanisms in rats.

Abstract
BACKGROUND Nephropathy is a frontline complication of diabetes mellitus (DM) associated with impaired redox-inflammatory networks. The study investigated the antidiabetic and nephroprotective potentials of PCR against diabetic nephropathy (DN) in rats. METHODS DN was induced in rats using a combination of a high fructose solution for 4 weeks and an intraperitoneal injection of streptozotocin (35 mg/kg). Diabetic rats were treated with PCR (100 and 400 mg/kg body weight) for 8 weeks. Serum biochemical parameters as well as renal oxidative stress parameters, proinflammatory cytokines, Western blot and histopathological analyses were evaluated. RESULTS There were significant increases in fasting blood glucose, urinary albumin, serum creatinine, blood urea nitrogen (BUN), total cholesterol (TC), triglycerides (TG), and low-density lipoproteins (LDL-C) levels in diabetic rats compared to the non-diabetic control rats. DM-induced DN prominently depressed renal superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities, whereas renal malondialdehyde (MDA) level was markedly increased. Furthermore, renal inflammatory cytokines, IL-1β, IL-6, TNF-α and TGF-β, were considerably elevated compared to non-diabetic control rats. Additionally, DN rats showed a significant increase in renal fibrosis, as evidenced by increased expression of TGF-β1, collagen-1, fibronectin and alpha-smooth muscle actin (α-SMA) in the kidneys. Histopathological lesions were consistent with tubule thickening and glomerular hypertrophy. Conversely, PCR treatment exerted significant attenuation of hyperglycemia, dyslipidemia and renal oxidative stress indicators. The increased renal levels of IL-1β, IL-6, TNF-α and TGF-β were also notably reversed dose-dependently with alleviation of nephropathic histology. Furthermore, PCR reduced the expression of α-SMA, fibronectin, collagen-1 and TGF-β1 in the renal tissues. CONCLUSION Our results suggest that PCR displayed antidiabetic and nephroprotective effects against DN by impeding oxidative stress and inflammation. As such, PCR has potentials as a food supplement for alleviating renal dysfunction caused by diabetes.
