Flaxseed Oil ( Linum usitatissimum) Prevents Cognitive and Motor Damage in Rats with Hyperammonemia. Nutrients 2023; 15:4550. [PMID: 37960203 PMCID: PMC10647672 DOI: 10.3390/nu15214550] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 10/25/2023] [Accepted: 10/25/2023] [Indexed: 11/15/2023] Open
Abstract
Hyperammonemia is characterized by the excessive accumulation of ammonia in the body as a result of the loss of liver detoxification, leading to the development of hepatic encephalopathy (HE). These metabolic alterations carry cognitive and motor deficits and cause neuronal damage, with no effective treatment at present. In this study, we aimed to evaluate the effect of two subacute oral administrations of flaxseed oil (0.26 and 0.52 mL/kg) on short- and long-term memory, visuospatial memory, locomotor activity, motor coordination, and the neuronal morphology of the prefrontal cortex (PFC) via tests on Wistar rats with hyperammonemia. The goal was to identify its role in the regulation of cerebral edema, without liver damage causing cerebral failure. In contrast with an ammonium-rich diet, flaxseed oil and normal foods did not cause cognitive impairment or motor alterations, as evidenced in the short-term and visuospatial memory tests. Furthermore, the flaxseed oil treatment maintained a regular neuronal morphology of the prefrontal cortex, which represents a neuroprotective effect. We conclude that the oral administration of flaxseed oil prevents cognitive and motor impairments as well as neuronal alterations in rats with hyperammonemia, which supports the potential use of this oil to ameliorate the changes that occur in hepatic encephalopathy.

Abstract
INTRODUCTION In this study, the effects of omega-3 fatty acids were examined in a rat model of spinal cord injury. METHODS The rats were classified into sham, control, spinal cord injury plus 50 mg/kg Omega-3 fatty acids and spinal cord injury plus 100 mg/kg Omega-3 fatty acids. The levels of oxidative, apoptotic, and inflammatory markers were examined in each of these groups. RESULTS Altered lipid peroxidation, reduced glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (Gpx), and catalase were normalized. Omega-3 fatty acid supplementation decreased tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) levels by >50%. TNF-α and IL-6 mRNA expression were reduced. Caspase-3, p53, bax, and pro-NGF mRNA expression levels were increased by 1.3-, 1.4-, 1.2-, and 0.9-fold, respectively, whereas bcl-2 mRNA expression was decreased by 0.77-fold in control rats. Omega-3 fatty acid supplementation decreased p53, caspase-3, bax, and pro-NGF mRNA expression by >40%, while the level of bcl-2 mRNA expression was increased by 286.9%. Omega-3 fatty acid supplementation decreased caspase-3 and p53 protein expression by >30%. CONCLUSION Taken together, our results suggested that omega-3 fatty acid supplementation reduced oxidative stress, apoptosis, and the levels of inflammatory markers in ischemia-reperfusion-induced rats.

Abstract
Omega-3 fatty acids are gaining attention as a therapeutic agent of many diseases. Their protective effect in a variety of diseases has been demonstrated. To the best of our knowledge, this is the first study on omega-3 fatty acids related to acute cold-restraint stress (CRS) induced hepatic dysfunction in rats. Forty adult male Sprague-Dawley albino rats were used and classified into: control, omega-3 group, each rat was pretreated with omega-3 fatty acids; CRS group, rats were subjected to acute CRS for 6 hr; and CRS group pretreated with omega-3 fatty acids. Serum was obtained to determine corticosterone (CORT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and tumor necrosis factor-α (TNF-α) levels. Hepatic malondialdehyde (MDA) and total antioxidant capacity (TAC) levels were measured. Also, liver tissues were taken for histological examination and immunohistochemical assessment of the apoptotic marker, caspase-3. Results showed that pretreatment of stressed rats with omega-3 fatty acids led to significant decrease in hepatic MDA and increase in TAC levels. They reduced serum levels of CORT, ALT, AST, and TNF-α. Also, they improved liver damage and suppressed hepatic caspase-3 expression. In conclusion, pretreatment of stressed rats with omega-3 fatty acids has ameliorated stress-induced liver damage due to their antioxidant, anti-inflammatory, and antiapoptotic effects. So, they can be used to minimize stress complications on the liver.

Abstract
The targeting protein for Xenopus kinesin-like protein 2 (TPX2) has been demonstrated to be associated with the tumourigenesis of many cancers. In the present study, we investigated the role and preliminary mechanism of TPX2 in the resistance of lung squamous carcinoma to radiation therapy. The results showed that SK-MES-1R and NCI-H226R cells were more resistant to X-ray irradiation than the parental cells (SK-MES-1 and NCI-H226). Moreover, TPX2 was upregulated in the radioresistant cells compared with the parental cells. TPX2 knockdown significantly decreased TPX2 expression in SK-MES-1 cells, while TPX2 overexpression increased TPX2 expression in NCI-H226 cells compared with the corresponding control cells. TPX2 knockdown enhanced the radiosensitivity of SK-MES-1 and promoted cell apoptosis following exposure to irradiation, whereas TPX2 overexpression decreased the radiosensitivity of NCI-H226 and inhibited cell apoptosis. In in vivo studies, the combination of TPX2 knockdown and irradiation significantly inhibited tumour growth, decreased tumour weight, downregulated TPX2 expression in tumour tissue and induced cell apoptosis in nude mice, while TPX2 overexpression exerted an opposite effect. Our results indicated that TPX2 was correlated with cell radioresistance and it might be served as a therapeutic target to enhance cell radiosensitivity in the radiation therapy of lung squamous carcinoma.

Abstract
The microbial population residing within the human gut represents one of the most densely populated microbial niche in the human body with growing evidence showing it playing a key role in the regulation of behavior and brain function. The bidirectional communication between the gut microbiota and the brain, the microbiota-gut-brain axis, occurs through various pathways including the vagus nerve, the immune system, neuroendocrine pathways, and bacteria-derived metabolites. This axis has been shown to influence neurotransmission and the behavior that are often associated with neuropsychiatric conditions. Therefore, research targeting the modulation of this gut microbiota as a novel therapy for the treatment of various neuropsychiatric conditions is gaining interest. Numerous factors have been highlighted to influence gut microbiota composition, including genetics, health status, mode of birth, and environment. However, it is diet composition and nutritional status that has repeatedly been shown to be one of the most critical modifiable factors regulating the gut microbiota at different time points across the lifespan and under various health conditions. Thus the microbiota is poised to play a key role in nutritional interventions for maintaining brain health.
