[PMID: 35400955 PMCID: PMC8980372 DOI: 10.14202/vetworld.2022.383-389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Accepted: 01/18/2022] [Indexed: 11/16/2022] Open
Abstract
Background and Aim: Muscle atrophy is common in Parkinson’s disease (PD). Although myostatin has been implicated in muscle atrophy, its expression in PD skeletal muscle has not been investigated. Therefore, this study aimed to elucidate the influence of PD induction and exercise training on myostatin expression in the gastrocnemius skeletal muscle. Materials and Methods: Thirty albino mice were randomly selected and separated into three groups of 10 mice each: Sedentary control, sedentary PD (SPD), and exercised PD (EPD). 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine and probenecid were used to induce chronic parkinsonism in the PD groups. Immunohistochemistry was used to investigate the expression of myostatin and nuclear factor kappa B (NF-kB) in gastrocnemius muscles of all three groups. Results: Myostatin expression and NF-kB nuclear localization, indicative of its activation, were significantly (p<0.01) higher in gastrocnemius skeletal muscle in the SPD group than in the control and EPD groups. Concomitantly, the average cross-sectional area of gastrocnemius muscle fibers in the SPD albino mice was significantly smaller (p<0.01) than in the control and EPD groups, indicating muscle atrophy. Conclusion: The present data are the first to indicate a correlation between PD induction and myostatin overexpression and NF-kB activation in the gastrocnemius muscle, potentially promoting the muscle atrophy commonly seen in PD. Additionally, the current data are the first to indicate the beneficial effects of exercise training on PD-associated myostatin overexpression, NF-κB activation, and muscle atrophy. Thus, our data are the first to suggest that myostatin and NF-κB might be regarded as potential therapeutic targets in an attempt to ameliorate skeletal muscle abnormalities commonly observed in PD.

Abstract
Parkinson's disease (PD) is a progressive disabling brain disorder. Physical exercise has been shown to alleviate the symptoms of PD and, consequently, improve patient quality of life. Exercise mechanisms involved in beneficial effects on PD have been widely investigated. This study aims to systematically review the literature on the use of treadmill exercise in PD animal models. The study was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Searches were conducted in MEDLINE, EMBASE, and ISI databases. In total, 78 studies were included. The dopaminergic system, behavior, neuroplasticity, neuroinflammation, mitochondria, and musculoskeletal systems were some of the outcomes evaluated by the selected studies. Based on the systematic review center for laboratory animal experimentation (SYRCLE) RoB tool, the methodologies revealed a high risk of bias and lack of information about study design, which needs attention for data reproducibility. This review can guide future studies that aim to fill existing gaps regarding the effects of treadmill exercise in PD animal models.

Abstract
BACKGROUNDWe have shown elevated levels of p53 and active caspase-3 in the heart with Parkinson disease (PD). The main aim of this study is to examine the effect of treadmill training on the cardiac expression of p53 and active caspase-3 in the mouse with induced Parkinsonism. METHODS Thirty randomly selected normal albino mice were equally divided into the following 3 groups: sedentary control (SC), sedentary Parkinson diseased (SPD), and exercised Parkinson diseased (EPD). 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and probenecid (MPTP/p) were used to induce chronic Parkinson disease in the SPD and EPD animals. The expression of p53 and active caspase-3 was investigated, using immunohistochemistry, in the heart in each animal group. RESULTS Both p53 and active caspase-3 expression was significantly (p value < 0.05) reduced in the PD heart following endurance exercise training. CONCLUSION Our present data suggest that chronic exercise training reduced PD-induced upregulation of p53 and active caspase-3 in the heart. Thus, our study suggests that inhibiting p53 and/or active caspase-3 may be considered as a therapeutic approach to ameliorate PD cardiomyopathy.

Abstract
As life expectancy has increased, particularly in developed countries, due to medical advances and increased prosperity, age-related neurological diseases and mental health disorders have become more prevalent health issues, reducing the well-being and quality of life of sufferers and their families. In recent decades, due to reduced work-related levels of physical activity, and key research insights, prescribing adequate exercise has become an innovative strategy to prevent or delay the onset of these pathologies and has been demonstrated to have therapeutic benefits when used as a sole or combination treatment. Recent evidence suggests that the beneficial effects of exercise on the brain are related to several underlying mechanisms related to muscle–brain, liver–brain and gut–brain crosstalk. Therefore, this review aims to summarize the most relevant current knowledge of the impact of exercise on mood disorders and neurodegenerative diseases, and to highlight the established and potential underlying mechanisms involved in exercise–brain communication and their benefits for physiology and brain function.

Abstract
Growing evidence has shown the beneficial influence of exercise on humans. Apart from classic cardioprotection, numerous studies have demonstrated that different exercise regimes provide a substantial improvement in various brain functions. Although the underlying mechanism is yet to be determined, emerging evidence for neuroprotection has been established in both humans and experimental animals, with most of the valuable findings in the field of mental health, neurodegenerative diseases, and acquired brain injuries. This review will discuss the recent findings of how exercise could ameliorate brain function in neuropathological states, demonstrated by either clinical or laboratory animal studies. Simultaneously, state-of-the-art molecular mechanisms underlying the exercise-induced neuroprotective effects and comparison between different types of exercise will be discussed in detail. A majority of reports show that physical exercise is associated with enhanced cognition throughout different populations and remains as a fascinating area in scientific research because of its universal protective effects in different brain domain functions. This article is to review what we know about how physical exercise modulates the pathophysiological mechanisms of neurodegeneration.

Abstract
Active caspase-3-mediated apoptosis has been implicated in the pathogenesis of
harmaline-induced tremor. The aim of this study is to illustrate the impact of
tremor induction on the expression of factors mediating the cell surface death
receptor–dependent apoptosis. A total of 20 normal Wistar rats were randomly
selected and equally divided into control and experimental groups. Tremor was
induced in the experimental group by injecting the rats with a single dose of
harmaline (50 mg/kg). After that, cerebellar tissues were evaluated by
immunohistochemistry to examine the expression of tumor necrosis factor α
(TNF-α) and active caspase-8 in the 2 groups of animals. TNF-α and active
caspase-8 expression was significantly higher in cerebella from experimental
rats compared with that in those from the control rats (P
value < .01). Thus, our present data suggest the association of tremor
induction with the cerebellar overexpression of TNF-α and active caspase-8,
correlative with Purkinje cell (PC) loss indicated by loss of calbindin
immunoreactivity, indicating the induction of the cell surface death
receptor–mediated apoptosis.

Abstract
BACKGROUND Skeletal muscle atrophy has been reported in patients with Parkinson disease (PD). The purpose of this study was to examine the potential implication of interleukin 1 beta (IL-1β), tumor necrosis factor alpha (TNFα), and nuclear factor kappa B (NF kappa B) in skeletal muscle atrophy following PD induction. MATERIAL AND METHODS Chronic Parkinsonism was induced in 10 albino mice by MPTP/probenecid treatment, while 10 other albino mice remained without treatment and were subsequently used as controls. Gastrocnemius muscles were examined for the expression of IL-1β and TNF-α, as well as the nuclear localization of NF kappa B, indicative of its activation, using immunohistochemistry in the 2 different groups. RESULTS IL-1β and TNF-α expression and NF kappa B nuclear localization were significantly higher in the PD skeletal muscle compared with those in the controls (P value <0.01). CONCLUSIONS The present data are indicative of an association of PD with IL-1β and TNF-α upregulation and NF kappa B activation in gastrocnemius muscles, potentially promoting the atrophy frequently observed in PD.

Abstract
Parkinson's disease is caused by damage to substantia nigra dopaminergic neurons. Factors such as oxidative stress, inflammatory factors, and acetylcholinesterase activity may induce this disease. On the other hand, crocin-one of the active ingredients of saffron-has anti-oxidant and anti-inflammatory properties. This study was performed to evaluate the protective effect of crocin to decrease dopaminergic neuron damage and Parkinson's disease complications induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). A set of 24 male BALB/c Mice were divided randomly into four groups: (1) MPTP group receiving 30 mg/kg MPTP for 5 days; (2) MPTP + crocin group receiving 30 mg/kg MPTP for 5 days and 30 mg/kg crocin for 15 days; (3) NS group receiving normal saline for 5 days; and (4) NSIG group receiving normal saline intraperitoneally for 5 days and also normal saline by gavage for 15 days. After the treatment period, pole and hanging motor tests were performed in all groups. Then, the brains of all the animals were removed and fixed in formalin, prepared according to routine histologic methods and cut into sections of 5 µm thickness. Prepared sections were stained by immunohistochemistry techniques and toluidine blue to detect tyrosine-hydroxylase (TH)-positive neurons and dark neurons, respectively. Finally, the mean number of these cells were calculated by stereological methods and compared with the statistical tests in different groups. The results showed a significant increase in the time taken for the animal to fall from the pole in the MPTP group in comparison with other groups (P < 0.001). The time taken for them to stay on the wire in the hanging test decreased significantly in the MPTP group compared to the other groups (P < 0.001).,while in the MPTP + crocin group, the time to falling decreased (P < 0.05) and the time staying on the wire increased (P < 0.001) compared to the MPTP group. The number of TH-positive neurons in the MPTP group also decreased significantly in comparison with saline and MPTP + crocin groups (P < 0.001). The number of dark neuron sin the MPTP group increased significantly as compared with saline and the MPTP + Crocin groups (P < 0.001). Our results showed that crocin improves MPTP-induced Parkinson's disease complications and decreases cell death in the substantia nigra.
