Aerobic Exercise Ameliorates Cognitive Disorder and Declined Oxidative Stress via Modulating the Nrf2 Signaling Pathway in D-galactose Induced Aging Mouse Model. Neurochem Res 2024:10.1007/s11064-024-04164-2. [PMID: 38839706 DOI: 10.1007/s11064-024-04164-2] [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: 10/14/2023] [Revised: 03/03/2024] [Accepted: 05/22/2024] [Indexed: 06/07/2024]
Abstract
The aim of this research was to explore the potential of treadmill exercise in preventing brain aging and neurodegenerative diseases caused by oxidative stress, by studying its effects on D-galactose-induced mice and the mechanisms involved. The results showed that C57BL/6 mice induced with D-gal exhibited cognitive impairment and oxidative stress damage, which was ameliorated by treadmill exercise. The Morris water maze also showed that exercise improved cognitive performance in aging mice and alleviated hippocampal and mitochondrial damage. The study also found that treadmill exercise increased the expression of nuclear factor Nrf2, p-GSK3β, HO-1, NQO1, BDNF, and Bcl-2 proteins while decreasing the expression of Bax. Furthermore, there was a substantial increase in the levels of CAT, GSH-PX and SOD in the serum, along with a decrease in MDA levels. The outcomes propose that aerobic exercise has the potential to hinder oxidative stress and cell death in mitochondria through the modulation of the Nrf2/GSK3β signaling pathway, thus improving cognitive impairment observed in the aging model induced by D-galactose. It appears that treadmill exercise could potentially serve as an effective therapeutic approach to mitigating brain aging and neurodegenerative diseases triggered by oxidative stress.

Neuroprotective activity of green synthesized silver nanoparticles against methamphetamine-induced cell death in human neuroblastoma SH-SY5Y cells. Sci Rep 2023; 13:11867. [PMID: 37481580 PMCID: PMC10363122 DOI: 10.1038/s41598-023-37917-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Accepted: 06/29/2023] [Indexed: 07/24/2023] Open
Abstract
The present study aimed to investigate the neuroprotective activity of the black peel pomegranate extract, and silver nanoparticles (AgNPs) biosynthesized using the extract. We pretreated the human neuroblastoma SH-SY5 cells with the extract and AgNPs and evaluated the neuroprotective activity of these agents against methamphetamine (Meth) cytotoxicity. The NPs were spherical with 19 ± 8 nm size, - 28 mV surface charge, and 0.20 PDI. Meth killed the cells by increasing proapoptotic (Bax, PTEN, AKT, PI3K, NF-κB, P53, TNF-α, Cyt C, and Cas 3) and decreasing the antiapoptotic genes (Bcl-2) expression. Exposure to Meth caused DNA fragmentation and increased the intercellular ROS and malondialdehyde (MDA) levels while reducing the mitochondrial membrane potential (MMP). A 4-h pretreatment of the cells with the extract and AgNPs could retain the viability of the cells above 80% by increasing the Bcl-2 expression up to fourfold and inhibiting the cell death pathways. ROS, MDA, and MMP levels in the pretreated cells were close to the control group. The percentage of necrosis in cells pretreated with the extract and AgNPs declined to 32% and 8%, respectively. Our promising findings indicated that AgNPs could reduce Meth-induced oxidative stress and prevent necrotic and apoptotic cell death by regulating related genes' expression.

Low and high dose methamphetamine differentially regulate synaptic structural plasticity in cortex and hippocampus. Front Cell Neurosci 2022; 16:1003617. [PMID: 36406748 PMCID: PMC9666390 DOI: 10.3389/fncel.2022.1003617] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 10/19/2022] [Indexed: 03/24/2024] Open
Abstract
Psychostimulants, such as methamphetamine (METH) can induce structural remodeling of synapses by remodeling presynaptic and postsynaptic morphology. Escalating or long-lasting high dose METH accounts for neurodegeneration by targeting multiple neurotransmitters. However, the effects of low dose METH on synaptic structure and the modulation mechanism remain elusive. This study aims to assess the effects of low dose (2 mg/kg) and high dose (10 mg/kg) of METH on synaptic structure alternation in hippocampus and prefrontal cortex (PFC) and to reveal the underlying mechanism involved in the process. Low dose METH promoted spine formation, synaptic number increase, post-synaptic density length elongation, and memory function. High dose of METH induced synaptic degeneration, neuronal number loss and memory impairment. Moreover, high dose, but not low dose, of METH caused gliosis in PFC and hippocampus. Mechanism-wise, low dose METH inactivated ras-related C3 botulinum toxin substrate 1 (Rac1) and activated cell division control protein 42 homolog (Cdc42); whereas high dose METH inactivated Cdc42 and activated Rac1. We provided evidence that low and high doses of METH differentially regulate synaptic plasticity in cortex and hippocampus.

Jia D, Xu Y. Effects of an 8-week Baduanjin intervention combined with low-carbohydrates diet among overweight people who struggle with drug addiction. Front Public Health 2022; 10:989519. [PMID: 36339240 PMCID: PMC9633992 DOI: 10.3389/fpubh.2022.989519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 09/30/2022] [Indexed: 11/12/2022] Open
Abstract
Background Prior studies have consistently revealed that a combination of physical activity with caloric restriction results in a reduction in body weight in the general population. Both overweight and drug abuse are risk factors for poor physiological health, and poor mental health has been associated with drug abuse and unhealthy body mass index (BMI). However, the effects of low-carbohydrates diet (LC) combined with mind-body exercise intervention on improving anthropometric characteristics, lipid metabolism, quality of life, and craving among overweight people who struggle with drug addiction have yet to be clarified. Methods Fifty-four eligible male patients were randomly assigned to the control group (CON; n = 18), the Baduanjin intervention group (BA, 60 min × 5 times/week, 8 weeks; n = 18), and the Baduanjin combined with LC intervention group (LC; n = 18). We compared the anthropometric characteristics, blood biochemical parameters, quality of life, and drug craving responses between the three groups at baseline (week 0), week 4, and week 8. Results After repeated measurements in the general linear model, both the BA and LC groups exerted significant effects on decreasing waist circumference, BMI, body weight, hip circumference, body fat percentage, total cholesterol level, and triglyceride level (P < 0.05). There was no significant difference in the HDL-C level observed among the BA and LC groups at 8 weeks (P > 0.05); however, there was an overall upwards trend. A significant change in trends in the quality of life scale score was determined in the three groups (P < 0.001). The three groups showed reductions in visual analog scale score distribution over time (P < 0.05). Conclusions Either Baduanjin or an 8-week Baduanjin combined with LC can significantly reduce anthropometric characteristics and body composition, enhance the quality of life, and reduce craving in overweight/obese patients. Baduanjin combined with LC is particularly effective in improving lipid metabolism.
