IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2024; 27:170-179. [PMID: 38234664 PMCID: PMC10790299 DOI: 10.22038/ijbms.2023.72553.15780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 09/26/2023] [Indexed: 01/19/2024]
Abstract
Objectives This study focused on the evaluation of antioxidant and antidiabetic activities of polyherbal extract (PHE), containing Cassia absus (L.), Gymnema sylvestre (R. Br.), Nigella sativa (L.), and Piper nigrum (L.), in alloxan-induced diabetes model. Materials and Methods In vitro, HPLC characterization, DPPH scavenging assay, and α-amylase inhibition test were conducted. In vivo, acute oral toxicity of PHE was assessed. Alloxan-induced diabetic Wistar rats (n=6) were orally treated with PHE (200, 400, and 600 mg/kg/day) and glibenclamide (GLB; 10 mg/kg/day) for six consecutive weeks. Then, biochemical biomarkers, oxidative stress parameters, histopathological examination, and mRNA expression levels (RT-qPCR) were determined. Results The presence of polyphenols in PHE was confirmed in correlation to marked DPPH scavenging (IC50: 1.60 mg/ml) and α-amylase inhibition (IC50: 0.82 mg/ml). PHE demonstrated no toxicity in rats up to a dose of 2000 mg/kg. In diabetic rats, PHE dose-dependently ameliorated the serum levels of glucose, insulin, glycated hemoglobin A1c (HbA1c), leptin, and glucokinase (GCK). Also, PHE substantially alleviated serum inflammatory markers (TNF-α and CRP) and oxidative stress indicators (MDA, SOD, and CAT) in pancreatic tissues. PHE, particularly at 600 mg/kg, attenuated cellular oxidative stress via modulating the mRNA expression levels of genes regulating MAPK/JNK (Mapk-8, Traf-4, and Traf-6) and Nrf-2/Keap-1 pathways and promoted insulin signaling through up-regulating insulin signaling cascade (Pdx-1, Ins-1, and Ins-2), as compared to GLB. Furthermore, histopathological findings supported the aforementioned results. Conclusion Our study suggests that polyherbal extract has promising antioxidant and antidiabetic activities by modulating the MAPK/JNK, Nrf-2/Keap-1, and insulin signaling pathways.

Rep Biochem Mol Biol 2023; 12:159-172. [PMID: 37724153 PMCID: PMC10505469 DOI: 10.52547/rbmb.12.1.159] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 02/12/2023] [Indexed: 09/20/2023]
Abstract
Background Serum and glucocorticoid-induced kinase 1 (SGK1) is an enzyme that may play an important role in ischemic-reperfusion (I/R) injury and myocardial dysfunction. Although many studies have been conducted on individual antioxidants, little attention has been paid to the effects of co-administration of an antioxidant with an SGK1 inhibitor on cardiac function after I/R. Methods This study aimed to determine the effects of gallic acid (as an antioxidant) combined with an SGK1 inhibitor on I/R-induced cardiac dysfunction and inflammation. Sixty male Wistar rats were randomized into 6 groups, pretreated with gallic acid or vehicle for 10 days. Subsequently, the heart was isolated and exposed to I/R. In groups that received the SGK1 inhibitor, the heart was perfused with the SGK1 inhibitor GSK650394, 5 min before induction of ischemia. After that, cardiac function, inflammatory factors, and myocardial damage were evaluated. Results The combination of these two compounds improved cardiac contractility, heart rate, rate pressure product, left ventricular developed pressure, left ventricular systolic pressure, perfusion pressure, and QRS voltage significantly (P < 0.05). In addition, concomitant therapy of these two agents reduced tumor necrosis factor-alpha and interleukin-6, and the activity of creatine kinase-MB, lactate dehydrogenase, and troponin-I (P < 0.05). Conclusion The results indicated that administration of gallic acid with the SGK1 inhibitor may have a potentiating effect on the improvement of cardiac dysfunction and I/R-induced inflammation.

GASTROENTEROLOGY AND HEPATOLOGY FROM BED TO BENCH 2023; 16:499-508. [PMID: 37070111 PMCID: PMC10105510 DOI: 10.22037/ghfbb.v16i1.2620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 11/06/2022] [Indexed: 04/19/2023]
Abstract
Aim This study aims to evaluate whether biochemical alterations caused by methylglyoxal (MG), improves by the administration of gallic acid (GA), crocin (Cr), and metformin (MT) in the liver. Background MG is produced naturally through various physiological processes, but high levels of MG cause inflammation in hepatocytes. Normal liver function is essential for maintaining glucose homeostasis. Gallic acid and crocin can reduce inflammation. Methods This experiment was done in 5 weeks. 50 male NMRI mice were randomly divided into 5 groups (n=10): 1) Control, 2) MG (600 mg/Kg/d, p.o.), 3) MG+GA (30 mg/kg/day, p.o.), 4) MG+Cr (60 mg/kg/day, p.o.), 5) MG+MT (150 mg/kg/day, p.o.). After one week of habituation, MG was administered for four weeks. Gallic acid, crocin, and metformin were administered in the last two weeks. Biochemical and histologic evaluations were assessed after plasma collection and tissue sample preparation. Results Gallic acid and crocin-received groups significantly reduced fasting blood glucose, total cholesterol, triglyceride levels, and elevated insulin sensitivity. Administration of MG exerted a marked increase in the levels of hepatic enzymes. Treatment with gallic acid, crocin, and metformin significantly decreased them. The altered levels of inflammatory factors in the diabetic group were significantly improved in the diabetic-treated groups. High levels of steatosis and red blood cells (RBCs) accumulation in the MG group markedly recovered in other treated mice. Conclusion Harmful effects of accumulated MG in the liver of diabetic mice were effectively attenuated by using gallic acid and crocin.

IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2022; 25:1433-1441. [PMID: 36544524 PMCID: PMC9742567 DOI: 10.22038/ijbms.2022.65646.14441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 10/22/2022] [Indexed: 12/24/2022]
Abstract
Objectives In this study, to find scientific evidence for the traditional use of Pergularia tomentosa as an anti-diabetic remedy, the effects of its aqueous extract on streptozotocin-induced diabetes mellitus in rats were evaluated. Materials and Methods Wistar rats were fasted overnight and diabetes mellitus was induced using streptozotocin (50 mg/kg body weight). The rats were randomly and equally divided into four groups (n=5): group I (normoglycaemic control), group II (diabetic rats), group III (diabetic rats treated with 200 mg/kg BW of an aqueous extract of P. tomentosa), group IV (normoglycemic rats treated with 200 mg/kg BW of an aqueous extract of P. tomentosa). Chemical profiling of the aqueous extract was carried out using liquid chromatography coupled with electrospray ionization and multiple-stage linear ion-trap and orbitrap high-resolution mass spectrometry (LC-ESI/LTQOrbitrap/MS/MS). In addition, the quantitative determination of the main cardenolides in the extract was carried out by an analytical approach based on LC coupled to tandem mass spectrometry with ESI source and hybrid triple quadrupole-linear ion trap mass analyzer (LC-ESI/QTrap/MS/MS). Results Aqueous extract of P. tomentosa showed a reasonable reduction in blood glucose level. Probably, the P. tomentosa effect on hyperglycemic and hyperlipidemic diabetic animals was associated with antioxidant properties, triglyceride levels, as well as liver enzymes. Meanwhile, LC-ESI/LTQOrbitrap/MS/MS analysis led to identification of double-linked cardenolides along with cardenolides and flavone glycosides as the main bioactive compounds. Conclusion The extract decreased the glucose level and induced a beneficial effect on the lipid profile, probably due to the presence of cardenolide glycosides.

Crocin attenuates endoplasmic reticulum stress in methylglyoxal-induced diabetic nephropathy in male mice: MicroRNAs alterations and glyoxalase 1-Nrf2 signaling pathways. IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2022; 25:1341-1348. [PMID: 36474578 PMCID: PMC9699949 DOI: 10.22038/ijbms.2022.65824.14479] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 09/26/2022] [Indexed: 01/25/2023]
Abstract
OBJECTIVES Accumulation of methylglyoxal (MGO) occurs in diabetes. MicroRNA-204 is an important intracellular marker in the diagnosis of endoplasmic reticulum stress. Crocin (Crn) has beneficial effects for diabetes, but the effect of Crn on MGO-induced diabetic nephropathy has not been investigated. The current research evaluated the effects of Crn and metformin (MET) on diabetic nephropathy induced by MGO in male mice. MATERIALS AND METHODS In this experimental study, 70 male NMRI mice were randomly divided into 7 groups: control, MGO (600 mg/Kg/d), MGO+Crn (15, 30, and 60 mg/kg/d), MGO+MET (150 mg/kg/d), and Crn60 (60 mg/kg/d). Methylglyoxal was gavaged for four weeks. After proving hyperglycemia, Cr and MET were administered orally in the last two weeks. Biochemical and antioxidant evaluations, microRNA expression, and histological evaluation were assessed. RESULTS The fasting blood glucose, urine albumin, blood urea nitrogen, plasma creatinine, malondialdehyde, Nrf2, miR-204, and miR-192 expression increased in the MGO group. These variables decreased in Crn-treated animals. The decreased levels of superoxide dismutase, catalase, glyoxalase 1, Glutathione, and miR-29a expression in the MGO group improved in the diabetic-treated mice. Histological alterations such as red blood cell accumulation, inflammation, glomerulus diameter changes, and proximal cell damage were also observed. CONCLUSION Our study indicated that Crn and MET attenuated renal damage by inhibiting endoplasmic reticulum stress.
