[PMID: 38725697 PMCID: PMC11077335 DOI: 10.1002/agm2.12301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/24/2024] [Accepted: 03/28/2024] [Indexed: 05/12/2024] Open
Abstract
Circadian rhythms are oscillations in physiology and behavior caused by the circadian regulator. Cryptochromes, Periods, and Bmal1 are circadian clock genes that have been linked to aging and cancer. Human pathologies alter circadian clock gene expression, and transgenic rats with clock gene defects progress to cancer and age prematurely. In the growth of age-linked pathologies and carcinogenesis, cell proliferation and genome integrity play critical roles. The relationship concerning the cell cycle regulation and circadian clock is discussed in this article. The circadian clock controls the behavior and countenance of many main cell cycle and cell cycle check-point proteins, and cell cycle-associated proteins, in turn, control the activity and expression of circadian clock proteins. The circadian clock can be reset by DNA disruption, providing a molecular mechanism for mutual control amid the cell cycle and the clock. This circadian clock-dependent regulation of cell proliferation, composed with other circadian clock-dependent physiological functions including metabolism control, genotoxic and oxidative stress response, and DNA repair, unlocks new avenues for studying the processes of aging and carcinogenesis.

Abstract
A decline in immune response, exhibited in the form of immunosenescence and inflammaging, is an age-associated disturbance of the immune system known to predispose the elderly to a greater susceptibility to infection and poor vaccine response. Polysaccharides and polyphenols from botanicals are known for their immune modulation effects. Here we evaluated a standardized mushroom-based composition, UP360, from Aloe barbadensis, Poria cocos, and Rosmarinus officinalis, as a natural nutritional supplement for a balanced immune response in an accelerated aging mouse model. Immunosenescence was induced by continual subcutaneous injection of D-galactose (D-gal) at a dose of 500 mg/kg/day to CD-1 mice. UP360 was administered at oral doses of 200 and 400 mg/kg to the mice starting on the 5th week of D-gal injection. The study lasted for a total of 9 weeks. All mice were given a quadrivalent influenza vaccine at 3 µg/animal via intramuscular injection 14 days before the end of the study. A group of D-gal-treated mice treated at 400 mg/kg/day UP360 was kept without vaccination. Whole blood, serum, spleen homogenate, and thymus tissues were used for analysis. UP360 was found to improve the immune response as evidenced by stimulation of innate and adaptive immune responses, increase antioxidant capacity as reflected by augmented SOD and Nrf2, and preserve vital immune organs, such as the thymus, from aging-associated damage. The findings depicted in this report show the effect of the composition in activating and maintaining homeostasis of the immune system both during active infections and as a preventive measure to help prime the immune system. These data warrant further clinical study to explore the potential application of the mushroom-based composition as an adjunct nutritional supplement for a balanced immune response.

Abstract
Methyl Ganoderate E (MGE) is a triterpenoid derived from Ganoderma lucidum (Reishi), an edible mushroom, commonly processed into food forms such as soups, drinks, culinary dishes, and supplements. MGE has been shown to inhibit 3T3-L1 murine adipocyte differentiation when combined with other G. lucidum triterpenes. However, the specific effect of MGE on biological processes remains unknown. In this study, we present the first evidence of MGE's anti-aging effect in Caenorhabditis elegans. Through our screening process using the UPRER regulation ability, we evaluated a library of 74 pure compounds isolated from G. lucidum, and MGE exhibited the most promising results. Subsequent experiments demonstrated that MGE extended the lifespan by 26% at 10 μg ml-1 through daf-16, hsf-1, and skn-1-dependent pathways. MGE also enhanced resistance to various molecular stressors, improved healthspan, increased fertility, and reduced the aggregation of alpha-synuclein and amyloid-beta. Transcriptome data revealed that MGE promoted processes associated with proteolysis and neural activity, while not promoting cell death processes. Collectively, our findings suggest that G. lucidum MGE could be considered as a potential anti-aging intervention, adding to the growing list of such interventions.

Abstract
Gastrointestinal (GI) cancer is the most common cancer in the world and one of the main causes of cancer-related death. Clinically, surgical excision and chemotherapy are the main treatment methods for GI cancer, which is unfortunately accompanied with serious adverse reactions and drug toxicity, bringing irreversible damage to patients and seriously affecting the quality of life. Ganoderma lucidum (G. lucidum) has a long history of medicinal and edible use in China. Its bioactive compounds mainly include polysaccharides, triterpenes, and proteins, which have potential anti-tumor activities by inhibiting proliferation, inducing apoptosis, inhibiting metastasis, and regulating autophagy. Currently, there is no in-depth review on the anti-tumor effect of G. lucidum in GI cancer. Therefore, this review is an attempt to compile the basic characteristics, anti-GI caner mechanisms, and clinical application of G. lucidum, aiming to provide a reference for further research on the role of G. lucidum in the prevention and treatment of GI cancer from the perspective of traditional Chinese and western medicine.

Abstract
Arsenic is a common environmental pollutant and poses a serious threat to human and animal health. In this study, we used the ducks to mimic arsenic trioxide (ATO) exposure and investigated the mechanism of cardiac toxicity. The results indicated that ATO inhibited the body and organ growth of ducks, led to an increase in LDH content, and caused obvious deformity, ischemia infarction. It is found that ATO exacerbated the swell of mitochondrial and the contraction of cell nuclei in the heart of ducks through transmission electron microscopy (TEM). ATO also induced an increase in MDA content; inhibited the activation of the Nrf 2 pathway; downregulated the expression of mRNA and protein of Nrf 2, HO-1, and SOD-1; and upregulated the expression of mRNA and protein of Keap 1. At the same time, ATO induced apoptosis which not only upregulated the expression levels of mRNA and proteins (Caspase 3, Cyt-C, P53, Bax) but also decreased the mRNA and protein expression level of Bcl-2. These results indicated that ATO can lead to oxidative stress and apoptosis in the heart of ducks. In general, our research shows that ATO triggers mitochondrial dysfunction, oxidative stress, and apoptosis via Nrf 2/Caspase 3 signaling pathway in the heart of ducks.

Abstract
Aging is an inevitable physiological process associated with an imbalance in the oxidative defense system. Angelica sinensis, a kind of traditional Chinese medicine (TCM), has anti-oxidant effects and has been considered as a potential supplement in anti-aging treatment. Nevertheless, it has the disadvantages of slow efficacy and long duration of treatment. Fermentation, as an efficient biotechnological approach, is beneficial for improving the nutritional capacity of the material. Fermented TCMs are considered to be more effective. In this study, fermented Angelica sinensis (FAS) and non-fermented Angelica sinensis (NFAS) were used to investigate changes in the chemical constituents. Furthermore, the improvement effect of FAS on D-galactose-induced aging in mice and the potential mechanisms were explored. The results revealed that FAS and NFAS had different constituents under the influence of fermentation, such as 3-phenyllactic acid, L-5-hydroxytryptophan, taxifolin and methyl gallate. These elevated constituents of FAS might help increase the ability of FAS to improve aging. The aging model was established by intraperitoneal injection of D-galactose (2.5 g kg-1 day-1) for 44 days, and FAS (3 g kg-1 day-1) was administered daily by oral gavage after 2 weeks of induction with D-galactose. FAS was observed to significantly ameliorate changes associated with liver aging, such as reduction of MDA, AGEs and 8-OHdG. The contents of pro-inflammatory cytokines containing TNF-α, IL-1β and IL-6 were significantly suppressed in the FAS group. In addition, FAS activated Nrf2 signaling better than NFAS, improved the expression of Nrf2, HO-1, NQO1, GCLC, GCLM and GSS, and further increased the activities of SOD, CAT and other antioxidant enzymes in the liver. Simultaneously, it had a certain repair effect on the liver tissues of mice. The intestinal microbiota analysis showed that FAS could regulate the microbiota imbalance caused by aging, increase the ratio of Firmicutes/Bacteroidetes by 95% and improve the relative abundance of beneficial bacteria related to Nrf2 signaling, such as Lactobacillus. Besides, fecal metabolite analysis identified uric acid as an evidential metabolite, suggesting that FAS participates in purine metabolism to improve aging. Therefore, the regulation of intestinal microbiota and metabolism may be one of the important mechanisms of FAS in alleviating hepatic oxidative stress via the gut-liver axis. The results of this study could provide information for the future development of postbiotic products that may have beneficial effects on the prevention or treatment of aging.

[PMID: 36451797 PMCID: PMC9706316] [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: 06/10/2022] [Revised: 08/12/2022] [Accepted: 08/30/2022] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND AND AIM The brain is one of the most complex and crucial organs of our body. Its health is a matter of concern for all individuals as the number of aged people is increasing gradually in the world. Carica papaya is a ubiquitous plant, and its different parts possess neuroprotective effects against various neurodegenerative diseases. However, its brain anti-aging effects have remained uninvestigated. Therefore, this study has examined the brain anti-aging strength of C. papaya pulp and seeds extracts in D-galactose-induced aging rats. METHODS The rats were intraperitoneally injected with 150 mg/kg of D-galactose for 8 consecutive weeks to induce brain aging. In parallel, the rats of papaya pulp and papaya seed treated groups were injected with 150 mg/kg papaya pulp extract and 150 mg/kg papaya seed extract, respectively. The negative control group was only injected with 0.9% saline, whereas in the rats of the positive control group along with D-galactose 100 mg/kg VC was injected. After the treatment period, different neurobehavioral, neurochemical, and antioxidant analyses were performed to unmask the anti-aging strength of C. papaya pulp and seeds extracts. RESULTS C. papaya pulp and seed extracts significantly improved cognitive learning skills, memory, and muscular strength in aging rats while reducing stress and anxiety levels. Moreover, they enhanced neurotransmitters concentration and reduced oxidative stress. However, the anti-aging effects of C. papaya pulp were more significant than seeds. CONCLUSION These results suggest that both C. papaya pulp and seed extracts possess neuroprotective effects against brain aging or age-related brain deteriorations but the age-protecting capability of C. papaya pulp is higher than C. papaya seeds. Therefore, it could be utilized as a component to design a novel brain anti-aging drug. RELEVANCE FOR PATIENTS Brain aging is a natural process that every individual experiences in his life. The regular consumption of C. papaya can improve the quality of life by protecting neurons from age-related deteriorations.

Acidic oligosaccharide sugar chain combined with hyperbaric oxygen delays D-galactose-induced brain senescence in mice via attenuating oxidative stress and neuroinflammation. Neurosci Res 2022; 185:40-48.

Abstract
Aging is fundamental to neurodegeneration and dementia. Preventing oxidative stress and neuroinflammation are potential methods of delaying the onset of aging-associated neurodegenerative diseases. The acidic oligosaccharide sugar chain (AOSC) and hyperbaric oxygen (HBO) can increase the expression of antioxidants and have a neuroprotective function. In this study, we investigate the ability of AOSC, HBO, and AOSC + HBO to prevent D-gal-induced brain senescence. The Morris water maze and Y-maze test results showed that all three therapies significantly attenuated D-gal-induced memory disorders. A potential mechanism of this action was decreasing elevated levels of oxidative stress and neuroinflammation. The western blot and morphological results showed that all three therapies decreased D-gal-induced neuroinflammation and downregulated inflammatory mediators including the nuclear factor κ-light-chain-enhancer of activated B cells, cyclooxygenase-2, interleukin-1β, and tumor necrosis factor alpha. Taken together, our results indicated that AOSC, HBO, and AOSC + HBO therapies attenuated D-gal-induced brain aging in mice by repressing RAGE/NF-KB-induced inflammation, the activation of astrocytes and microglia, and a decrease in neuronal degeneration. These could be useful therapies for treating age-related neurodegenerative diseases such as Alzheimer's disease. Furthermore, HBO combined with AOSC had a better effect than HBO or AOSC alone.

Metabolomics and biochemical insights on the regulation of aging-related diabetes by a low-molecular-weight polysaccharide from green microalga Chlorella pyrenoidosa. Food Chem X 2022; 14:100316.

Abstract
C. pyrenoidosa polysaccharide (CPP) have hypoglycemic activity and oxidation resistance. CPP prevents oxidative stress and stimulates insulin via affecting phenylpyruvic acid. CPP can regulate the GLP-1R/IL-6R and ZO-1/MMP-2 pathways. CPP activated BCL-6 to promote cell survival in brain.
Globally, aging and diabetes are considered prevalent threats to human health. Chlorella pyrenoidosa polysaccharide (CPP) is a natural active ingredient with multiple health benefits including antioxidant and hypolipidemic activities. In this study, the aging-related diabetic (AD) mice model was established to investigate the underlying hypoglycemic and antioxidant mechanisms of CPP. It improved superoxide dismutase, catalase (CAT), glutathione peroxidase (GSH-px), and malondialdehyde activities in liver and insulin secretion. CAT and GSH-px activity in the brain increased after CPP administration. In addition, through histopathological examinations, it was evident that injuries in the liver, brain, jejunum, and pancreas were restored by CPP. This restoration was likely mediated via the activation of glucagon-like peptide-1 receptor/FOXO-1 (forkhead box O1) pathway concurrent with the inhibition of interleukin-6 receptor/FOXO-1 pathway. Furthermore, metabolomics and correlation analysis revealed that CPP possibly relived AD through changes in insulin levels and declined oxidative stress as regulated by phenylpyruvic acid. These findings suggested that CPP exerted antioxidant and hypoglycemic roles in an AD mice model, thereby providing a sound scientific foundation for further development and utilization of CPP.

[PMID: 35595806 PMCID: PMC9123171 DOI: 10.1038/s41598-022-12206-4] [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: 01/15/2022] [Accepted: 05/03/2022] [Indexed: 11/29/2022] Open
Abstract
We aimed to compare the time-course effect of D-galactose (D-gal)-induced aging, obesity, and their combined effects on bone homeostasis. Male Wistar rats were fed with either a normal diet (ND; n = 24) or a high-fat diet (HFD; n = 24) for 12 weeks. All rats were then injected with either vehicle or 150 mg/kg/day of D-gal for 4 or 8 weeks. Blood was collected to measure metabolic, aging, oxidative stress, and bone turnover parameters. Bone oxidative stress and inflammatory markers, as well as bone histomorphometry were also evaluated. Additionally, RAW 264.7 cells were incubated with either D-gal, insulin, or D-gal plus insulin to identify osteoclast differentiation capacity under the stimulation of receptor activator of nuclear factor κB ligand. At week 4, D-gal-induced aging significantly elevated serum malondialdehyde level and decreased trabecular thickness in ND- and HFD-fed rats, when compared to the control group. At week 8, D-gal-induced aging further elevated advanced glycation end products, increased bone inflammation and resorption, and significantly impaired bone microarchitecture in HFD-fed rats. The osteoclast number in vitro were increased in the D-gal, insulin, and combined groups to a similar extent. These findings suggest that aging aggravates bone dyshomeostasis in the obese condition in a time-dependent manner.

Front Pharmacol 2022; 13:816350.

Abstract
Objective: This work aims to explore the potential targets and underlying therapeutic mechanisms of celastrol in autoimmune hepatitis (AIH) through network pharmacology and experiments on Laboratory Animals. Methods: A drug-target interaction network was constructed to predict the possible targets of celastrol and their potential relationship with the drug; docking studies were also performed for validation. This study used both acute and chronic rodent models of autoimmune hepatitis. Gross appearance of liver and spleen were obtained from murine models, hematoxylin-eosin staining and Sirius red staining were performed to examine hepatic inflammation and fibrosis respectively. By combining molecular docking and enrichment analysis results, the most prominent signaling pathway was selected and further confirmed by Western blot in AIH models administered with celastrol. Results: In total, 82 common targets of celastrol and AIH were obtained from databases, identified by network pharmacology, and adequately enriched. Among them, PIK3R1, SRC, MAPK1, AKT1, and HRAS were selected as the top 5 closely related targets to celastrol. They all performed effectively in molecular docking, with AKT1 and PIK3R1 exhibiting more-prominent binding energy. Subsequently, celastrol administration significantly ameliorated hepatitis and liver fibrosis by reducing AKT1 and PI3K phosphorylation in both acute liver injury and chronic models of autoimmune hepatitis. Conclusion: In summary, celastrol significantly attenuates autoimmune hepatitis by suppressing the PI3K/AKT signaling pathway, confirmed by validated animal models. These findings may help identify the mechanism involved in the anti-inflammatory action of celastrol in autoimmune hepatitis and provide ideas for future comprehensive studies.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 273:113993. [PMID: 33684515 DOI: 10.1016/j.jep.2021.113993] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 02/26/2021] [Accepted: 02/27/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fructus Lycii and Salvia miltiorrhiza Bunge (FS) are popular Chinese herbs for the treatment of retinitis pigmentosa (RP). AIM OF THE STUDY This study was to evaluate protective effects of FS extract on RP and to explore whether FS extract exerts its protective effects via oxidative stress by regulating Nrf2/HO-1 signaling pathway. MATERIAL AND METHODS FS extract were identified by UPLC chromatographic analysis. Rd10 mice as the model of RP, followed by a 4-week FS extract treatment by intragastric administration. After the animal sacrifice, histopathological examination and Scotopic electroretinography (ERG) analysis were assessed. The oxidative stress markers were determined and the expression levels of Nrf2 and HO-1 mRNA were evaluated by qRT-PCR. The expression and distribution of Nrf2 and HO-1 protein were determined by Western blot and immunohistochemistry. RESULTS The morphological changes of Outer nuclear layer (ONL) thickness and number of the ONL were observed with a significant increased, and the functional changes of a-amplitude and b-wave amplitude were measured with a markedly increased. Treatment with FS extract remarkably increased levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and decreased level of malondialdehyde (MDA). Moreover, FS extract up-regulated mRNA and protein expression of Nrf2 and HO-1. CONCLUSIONS This study indicated that FS extract can improve retinal morphology and function, which may have occurred through the regulation of the Nrf2/HO-1 pathway to inhibit the oxidative reaction.
