Adropin increases with swimming exercise and exerts a protective effect on the brain of aged rats. Exp Gerontol 2022; 169:111972. [PMID: 36216130 DOI: 10.1016/j.exger.2022.111972] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 09/14/2022] [Accepted: 09/26/2022] [Indexed: 12/15/2022]
Abstract
Adropin is a protein in the brain that decreases with age. Exercise has a protective effect on the endothelium by increasing the level of adropin in circulation. In this study, whether adropin, whose level in the brain decreases with age, may increase with swimming exercise, and exhibit a protective effect was investigated. Young and aged male Sprague Dawley rats were submitted to 1 h of swimming exercise every day for 8 weeks. Motor activity parameters were recorded at the end of the exercise or waiting periods before the animals were euthanized. Increased motor functions were observed in only the young rats that exercised regularly. Adropin levels in the plasma, and the adropin and VEGFR2 immunoreactivities and p-Akt (Ser473) levels in the frontal cortex were significantly increased in the aged rats that exercised regularly. It was also observed that the BAX/Bcl2 ratio and ROS-RNS levels decreased, while the TAC levels increased in the aged rats that exercised regularly. The results of the study indicated that low-moderate chronic swimming exercise had protective effects by increasing the level of adropin in the frontal cortex tissues of the aged rats. Adropin is thought to achieve this effect by increasing the VEGFR2 expression level and causing Akt (Ser473) phosphorylation. These results indicated that an exercise-mediated increase in endogenous adropin may be effective in preventing the destructive effects of aging on the brain.

Abstract
One of the global alarming prevalent metabolic diseases is Type 2 diabetes mellitus (T2DM) than other diabetes and sustains a substantial burden on public and healthcare systems. This study attempts to endeavor the beneficial effect of chitosan stabilized nanoparticles Ch-SeNPs on combating diabetic nephropathy (DN) after induction of T2DM in rats (DN.STZ-induced T2D). High-fat diet (HFD) and STZ were used for the induction of T2DM in rats, and then they were treated with either metformin alone (MEF) (500 mg/kg b.wt.) or combined with (Ch-SeNPs) (2 mg Se/kg b.wt.) for eight weeks. The microvascular complications in renal tissue of diabetic rats were pronounced by the prevalence of microalbuminuria and elevated levels of urea, creatinine, and BUN. Pronounced oxidative stress with enhanced inflammatory response. In the urine of diabetic rats, a marked increase in Kim 1, β2-microglobulin, and urinary albumin. Renal morphological alterations were observed in all groups upon induction of T2DM, except for the Ch-SeNPs/MEF group showed noticeable improvements. The expression levels of Aldo-keto reductase AKr1B1, profibrotic protein transforming growth factor-β1 (TGF-β1), nestin, desmin, and vimentin, were up-regulated in the diabetic group. Significant down-regulation of their expression and restored antioxidant capacity was observed in the combined-treated group than single treated ones. Ch-SeNPs helped limit the prevalence of TNF-α, IL-6, and IL-1β while used after T2DM induction by STZ and HFD. Ch-SeNPs/MEF co-therapy could effectively guard the kidneys and reduce the renal tissue injury via inhibiting oxidative stress and restoring glucose hemostasis, which indicates a promising line for treating T2DM nephropathy.

Brain Behav 2021; 11:e01988. [PMID: 33471970 PMCID: PMC7994679 DOI: 10.1002/brb3.1988] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 11/05/2020] [Accepted: 11/20/2020] [Indexed: 12/12/2022] Open
Abstract
PURPOSE One of the most frequent complications associated with diabetes mellitus is apoptosis within the brain which can lead to cognitive disorders. Exercise is considered the best non-pharmacological approach to reduce the severity and extent of cell death through poorly-understood mechanisms. The aim of this study was to investigate the effects of voluntary complex and regular wheel running on the levels of 8-oxoguanine DNA glycosylase (OGG1 ), semaphorin 3B (sema3B), hydrogen peroxide (H2 O2 ), and apoptosis in the hippocampus of diabetic rats. METHODS 48 Wistar male rats were randomly divided into 6 groups: healthy control (C), diabetes control (D), regular wheel running + diabetes (RWD), complex wheel running + diabetes (CWD), healthy regular wheel running (RW), and healthy complex wheel running (CW). The diabetic rat model was produced by intraperitoneal injection of streptozotocin (STZ). The protocol encompassed a 4-week voluntary running training regimen on regular and complex wheel running apparatus. The rats were sacrificed 48 hr after the last training session. To measure the protein concentrations within the hippocampus, ELISA has been utilized. One-way ANOVA was used to compare the groups. RESULTS There were no significant differences in OGG1 protein levels between the groups. H2 O2 level in the D group was significantly higher than the C group (p = .002), while this in RWD and CWD groups was considerably lower than the D group (p = .002 and p = .003, respectively). In the D group, the levels of apoptosis and Sema3B were significantly (p = .001 and p = .007, respectively) higher than C, RWD (p = .001, p = .0001, respectively), and CWD groups (p = .001, p = .006, respectively). Nevertheless, there were not any significant differences between RWD and CWD groups. CONCLUSION The increased levels of Sema3B, H2O2, and apoptosis within the hippocampus associated with diabetes could be noticeably restored by both types of voluntary wheel running protocols.

Cognitive decline prevention in offspring of Pb +2 exposed mice by maternal aerobic training and Cur/CaCO 3@Cur supplementations: In vitro and in vivo studies. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2021; 209:111785. [PMID: 33348254 DOI: 10.1016/j.ecoenv.2020.111785] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 12/02/2020] [Accepted: 12/07/2020] [Indexed: 06/12/2023]
Abstract
Heavy metals are considered contaminants that hazardously influence the healthy life of humans and animals as they are widely used in industry. Contact of youngsters and women at ages of parturition with lead (Pb+2) is a main related concern, which passes through the placental barricade and its better absorption in the intestine leads to flaws in the fetal developfment. However, the metals threaten animal and human life, in particular throughout developmental stages. Products existing in the nature have a major contribution to innovating chemo-preventives. As a naturally available polyphenol and necessary curcuminoid, curcumin (Cur) is a derivative of the herb Curcuma longa (L.) rhizome, which globally recognized as "wonder drug of life"; however, Cur has a limited clinical use as it is poorly dissolved in water. Therefore, to enhance its clinically relevant parameters, curcumin-loaded calcium carbonate (CaCO3@Cur) was synthesized by one step coprecipitation method as a newly introduced in this research. Initially, its structure was physio chemically characterized using FT-IR, FESEM and DLS equipment and then the cytotoxicity of lead when it was pretreated with Cur/CaCO3@Cur were assessed by MTT assay. Both Cur and CaCO3@Cur diminished the toxic effects of Pb+2 while the most protective effect on the Pb+2 cytotoxicity was achieved by pre-incubation of cells with CaCO3@Cur. Besides, the morphological changes of Pb+2-treated cells that were pre-incubated with or without Cur/CaCO3@Cur were observed by normal and florescent microscopes. A non-pharmacologic method that lowers the hazard of brain damage is exercise training that is capable of both improving and alleviating memory. In the current study, the role of regular aerobic training and CaCO3@Cur was assessed in reducing the risk of brain damage induced by lead nitrate contact. To achieve the mentioned goal, pregnant Balb/C mice were assigned to five groups (six mice/group) at random: negative and positive controls, aerobic training group and Cur and CaCO3@Cur treated (50 mg/kg/b.wt) trained groups that exposed to Pb+2 (2 mg/kg) by drinking water during breeding and pregnancy. With the completion of study, offspring were subjected to the behavioral tasks that was tested by step-through ORT, DLB, MWM and YM tests. As a result, having regular aerobic training and CaCO3@Cur co-administration with lead nitrate could reverse the most defected behavioral indicators; yet, this was not visible for both sexes and it seems that gender can also be a source of different effects in the animal's body. In fact, having regular aerobic training along with CaCO3@Cur supplementation during pregnancy may be encouraging protecting potential agents towards the toxicity of Pb+2 that could be recommended in the areas with high pollution of heavy metals.

Abstract
In this study, the effect of geraniol (50 mg/kg for 30 d), a natural antioxidant and repellent/antifeedant monoterpene, in a rat model of lead acetate-induced (500 ppm for 30 d) liver damage was evaluated. Hepatic malondialdehyde increased in the lead acetate group. Reduced glutathione unchanged, but glutathione S-transferase, glutathione reductase, as well as carboxylesterase activities decreased in geraniol, lead acetate and geraniol + lead acetate groups. 8-OhDG immunoreactivity, mononuclear cell infiltrations and hepatic lead concentration were lower in the geraniol + lead acetate group than the lead acetate group. Serum aspartate aminotransferase and alanine aminotransferase activities increased in the Pb acetate group. In conclusion, lead acetate causes oxidative and toxic damage in the liver and this effect can reduce with geraniol treatment. However, we first observed that lead acetate, as well as geraniol, can affect liver carboxylesterase activity.

Abstract
HL-60 cells, derived from human promyelocytic leukemia, were exposed to continuous wave 900MHz radiofrequency fields (RF) at 120μW/cm2 power intensity for 4h/day for 5 consecutive days to examine whether such exposure is capable damaging the mitochondrial DNA (mtDNA) mediated through the production of reactive oxygen species (ROS). In addition, the effect of RF exposure was examined on 8-hydroxy-2'-dexoyguanosine (8-OHdG) which is a biomarker for oxidative damage and on the mitochondrial synthesis of adenosine triphosphate (ATP) which is the energy required for cellular functions. The results indicated a significant increase in ROS and significant decreases in mitochondrial transcription factor A, mtDNA polymerase gamma, mtDNA transcripts and mtDNA copy number in RF-exposed cells compared with those in sham-exposed control cells. In addition, there was a significant increase in 8-OHdG and a significant decrease in ATP in RF-exposed cells. The response in positive control cells exposed to gamma radiation (GR, which is also known to induce ROS) was similar to those in RF-exposed cells. Thus, the overall data indicated that RF exposure was capable of inducing mtDNA damage mediated through ROS pathway which also induced oxidative damage. Prior-treatment of RF- and GR-exposed the cells with melatonin, a well-known free radical scavenger, reversed the effects observed in RF-exposed cells.
