A novel approach to repositioning memantine for metabolic syndrome-induced steatohepatitis: Modulation of hepatic autophagy, inflammation, and fibrosis. Life Sci 2023; 319:121509. [PMID: 36822316 DOI: 10.1016/j.lfs.2023.121509] [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: 11/23/2022] [Revised: 02/07/2023] [Accepted: 02/16/2023] [Indexed: 02/25/2023]
Abstract
AIMS This study investigated the possible hepatoprotective effects of memantine, compared to pioglitazone, in rat steatohepatitis, emphasizing its role in modulating hepatic autophagy. MAIN METHODS Metabolic syndrome (MetS) was provoked in adult male Wistar rats by a high fructose/fat/salt regimen for eight weeks. Then, rats were administered either memantine or pioglitazone daily for 10 weeks (both at 20 mg/kg, orally). An oral glucose tolerance test (OGTT) was done at the end of the study, and serum liver enzymes, lipids, and fasting blood glucose were measured. Also, hepatic contents of inflammatory, oxidative, and autophagy markers were quantified. Additionally, histopathological examinations of general hepatic structure and glycogen content were performed. KEY FINDINGS Compared to the MetS rats, memantine normalized fasting serum insulin, Homeostatic Model Assessment (HOMA-IR), serum lipids, and liver enzymes (ALT and AST). Memantine also markedly reduced hepatic inflammatory markers; NF-κB and TNF-α. In addition, hepatic NRF2 and GSH were augmented, while hepatic MDA was reduced by memantine. Interestingly, livers of the memantine group showed elevated Beclin1 and LC3 and reduced p62 contents compared to the MetS group indicating that memantine preserved hepatic autophagy. Histopathological examination revealed that memantine ameliorated hepatic steatosis and inflammation. Pioglitazone also mitigated most of the steatohepatitis-related changes, however, memantine was more effective in most of the studied parameters. SIGNIFICANCE The hepatoprotective effect of memantine against steatohepatitis is mediated, at least partly, through conserving hepatic autophagy along with anti-inflammatory, antioxidant, and anti-fibrotic effects.

Abstract
Introduction Alzheimer's disease is the most common form of dementia and closely related to aging. Qi-Fu-Yin is widely used to treat dementia, but its anti-aging effects is unknown. Methods We used 11-month-old APP/PS1 transgenic mice for behavioral tests to observe the changes in cognitive function and age-related symptoms after Qi-Fu-Yin treatment. Fecal samples were collected for 16sRNA sequencing and metagenomic sequencing. Differences among the groups of intestinal microbiota and the associations with aging and intestinal microbiota were analyzed based on the results. Results Here we found that Qi-Fu-Yin improved the ability of motor coordination, raised survival rate and prolonged the survival days under cold stress stimulation in aged APP/ PS1 transgenic mice. Our data from 16sRNA and metagenomic sequencing showed that at the Family level, the intestinal microbiota was significantly different among wild-type mice, APP/PS1 transgenic mice and the Qi-Fu-Yin group by PCA analysis. Importantly, Qi-Fu-Yin improved the functional diversity of the major KEGG pathways, carbohydrate-active enzymes, and major virulence factors in the intestinal flora of APP/PS1 transgenic mice. Among them, the functions of eight carbohydrate-active enzymes (GT2_Glycos_transf_2, GT4, GT41, GH2, CE1, CE10, CE3, and GH24) and the functions of top three virulence factors (defensive virulence factors, offensive virulence factors and nonspecific virulence factors) were significantly and positively correlated with the level of grasping ability. We further indicated that the Qi-Fu-Yin significantly reduced the plasma levels of IL-6. Conclusion Our results indicated that the effects of Qi-Fu-Yin anti-aging of APP/PS1 transgenic mice might be through the regulation of intestinal flora diversity, species richness and the function of major active enzymes.

Abstract
Stress affects many organs in addition to the brain, including the liver. We assessed the effects on the liver of blocking N-methyl-d-aspartate (NMDA) glutamate receptors with memantine in acute and repeated restraint stress. Forty-two male albino rats were divided into 7 groups; control, acute restraint stress (ARS), ARS + memantine, repeated restraint stress, repeated restraint + memantine, and positive control groups. We measured serum iron, zinc, alanine transferase and aspartame transferase, hepatic malondialdehyde, tumor necrosis factor-α (TNF-α), glutathione peroxidase, superoxide dismutase, metallothionein content, zinc transporter ZRT/IRT-like protein 14 mRNA expression, and hepcidin expression. We conducted a histopathological evaluation via histological staining and immunostaining for glial fibrillary acidic protein and synaptophysin expression, both of which are markers of hepatic stellate cell (HSC) activation. Both ARS and repeated stress increased markers of hepatic cell injury, oxidative stress, and HSC activation. Blocking NMDA with memantine provided a hepatoprotective effect in acute and repeated restraint stress and decreased hepatic cell injury, oxidative stress, and HSC activation.

Abstract
Psychological stresses are associated with cardiovascular diseases to the extent that cardiovascular diseases are among the most important group of psychosomatic diseases. The longstanding association between stress and cardiovascular disease exists despite a large ambiguity about the underlying mechanisms. An array of possibilities have been proposed including overactivity of the autonomic nervous system and humoral changes, which then converge on endothelial dysfunction that initiates unwanted cardiovascular consequences. We review some of the features of the two most important stress-activated systems, i.e., the humoral and nervous systems, and focus on alterations in endothelial function that could ensue as a result of these changes. Cardiac and hematologic consequences of stress are also addressed briefly. It is likely that activation of the inflammatory cascade in association with oxidative imbalance represents key pathophysiological components of stress-induced cardiovascular changes. We also review some of the commonly used animal models of stress and discuss the cardiovascular outcomes reported in these models of stress. The unique ability of animals for adaptation under stressful conditions lessens the extrapolation of laboratory findings to conditions of human stress. An animal model of unpredictable chronic stress, which applies various stress modules in a random fashion, might be a useful solution to this predicament. The use of stress markers as indicators of stress intensity is also discussed in various models of animal stress and in clinical studies.
