Tetrahydroxy stilbene glucoside rejuvenates aging hematopoietic stem cells with predilection for lymphoid differentiation via AMPK and Tet2. J Adv Res 2024:S2090-1232(24)00170-X. [PMID: 38704089 DOI: 10.1016/j.jare.2024.04.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 03/26/2024] [Accepted: 04/26/2024] [Indexed: 05/06/2024] Open
Abstract
INTRODUCTION Aging of hematopoietic stem cells (HSCs) has emerged as an important challenge to human health. Recent advances have raised the prospect of rejuvenating aging HSCs via specific medical interventions, including pharmacological treatments. Nonetheless, efforts to develop such drugs are still in infancy until now. OBJECTIVES We aimed to screen the prospective agents that can rejuvenate aging HSCs and explore the potential mechanisms. METHODS We screened a set of natural anti-aging compounds through oral administration to sub-lethally irradiated mice, and identified 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside (TSG) as a potent rejuvenating agent for aging HSCs. Then naturally aged mice were used for the follow-up assessment to determine the HSC rejuvenating potential of TSG. Finally, based on the transcriptome and DNA methylation analysis, we validated the role of the AMP-activated protein kinase (AMPK)-ten-eleven-translocation 2 (Tet2) axis (the AMPK-Tet2 axis) as the underlying mechanisms of TSG for ameliorating HSCs aging. RESULTS TSG treatment not only significantly increased the absolute number of common lymphoid progenitors (CLPs) along with B lymphocytes, but also boosted the HSCs/CLPs repopulation potential of aging mice. Further elaborated mechanism research demonstrated that TSG supplementation restored the stemness of aging HSCs, as well as promoted an epigenetic reprograming that was associated with an improved regenerative capacity and an increased rate of lymphopoiesis. Such effects were diminished when the mice were co-treated with an AMPK inhibitor, or when it was performed in Tet2 knockout mice as well as senescent cells assay. CONCLUSION TSG is effective in rejuvenating aging HSCs by modulating the AMPK- Tet2 axis and thus represents a potential candidate for developing effective HSC rejuvenating therapies.

Abstract
Neuropsychiatric disorders are anticipated to be a leading health concern in the near future, emphasizing an outstanding need for the development of new effective therapeutics to treat them. Stilbenes, with resveratrol attracting the most attention, are an example of multi-target compounds with promising therapeutic potential for a broad array of neuropsychiatric and neurological conditions. This review is a comprehensive summary of the current state of research on stilbenes in several neuropsychiatric and neurological disorders such as depression, anxiety, schizophrenia, autism spectrum disorders, epilepsy, traumatic brain injury, and neurodegenerative disorders. We describe and discuss the results of both in vitro and in vivo studies. The majority of studies concentrate on resveratrol, with limited findings exploring other stilbenes such as pterostilbene, piceatannol, polydatin, tetrahydroxystilbene glucoside, or synthetic resveratrol derivatives. Overall, although extensive preclinical studies show the potential benefits of stilbenes in various central nervous system disorders, clinical evidence on their therapeutic efficacy is largely missing.

Huannao Yicong decoction ameliorates cognitive deficits in APP/PS1/tau triple transgenic mice by interfering with neurotoxic interaction of Aβ-tau. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116985. [PMID: 37532075 DOI: 10.1016/j.jep.2023.116985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 07/27/2023] [Accepted: 07/30/2023] [Indexed: 08/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huannao Yicong decoction (HYD) has been used in the study of AD for many years, which consists of Polygonum multiflorum Thunb., Panax ginseng C.A.Mey., Acorus gramineus Aiton, Coptis chinensis Franch., and Conioselinum acuminatum (Franch.) Lavrova. Previous studies have found that HYD could reduce β-Amyloid (Aβ) deposition and tau hyperphosphorylation which are the two critical pathological factors of AD. However, the mechanism of the neurotoxic interaction between Aβ and tau in AD remains unclear. Thus, the underlying mechanisms for HYD improving cognitive function of AD by interfering with the neurotoxic interaction between Aβ and tau remain to be explored. AIM OF THE STUDY The main objective of this study is to clarify the specific mechanisms of HYD on interfering with the neurotoxic interaction between Aβ and tau of AD both in vivo and in vitro. MATERIALS AND METHODS APP/PS1/tau triple transgenic mice were randomly divided into 4 groups, namely model group, memantine group, HYD low-dose group (HYD-L), and HYD high-dose group (HYD-H) with 28 mice in each group, while 28 C57BL/6J mice as the control group. Gavage was applied to all the mice daily for 24 weeks. SH-SY5Y model cells overexpressing Aβ and tau proteins as the intervention object in vitro experiments. Morris water maze was used to observe the learning and memory ability of APP/PS1/tau mice. Aβ deposition was detected by immunohistochemistry, and the levels of Aβ1-40 and Aβ1-42 were detected by enzyme-linked immunosorbent assay (ELISA). Neurofibrillary tangles (NFTs) were observed by silver staining and the levels of phosphorylated tau proteins were detected by Western blot. The GSK-3β and CDK-5 mRNA expression were detected by real-time polymerase chain reaction (RT-PCR). Besides, the levels of PSD95, GluR1, NR2A, and NR2B were detected by Western blot. Meanwhile, cell experiments were performed to further verify the effect of HYD on tau phosphorylation related kinases (GSK-3β, CDK-5, and PP2A), which further to clarify the mechanism of HYD intervention on the neurotoxic interaction between Aβ and tau. RESULTS HYD improved the learning and memory ability of APP/PS1/tau mice. HYD decreased the levels of Aβ1-40 and Aβ1-42 and inhibited tau hyperphosphorylation, which reduced Aβ deposition and NFTs forming. In addition, HYD inhibited the activity of kinases GSK-3β and CDK-5, and enhancing the activity of kinase PP2A. Moreover, HYD inhibited the overexpression of NR2A and NR2B, and increased the expression of GluR1 and postsynaptic density protein-95 (PSD95). CONCLUSIONS HYD can improve the cognitive deficits by interfering with the neurotoxic interaction between Aβ and tau. In addition, HYD can inhibit the overactivation of NMDARs and increase the levels of GluR1 and PSD95, which may play a role in alleviating neuronal excitotoxicity and improving synaptic function.

Abstract
The phenylpropanoid metabolism is the source of a vast array of specialized metabolites that play diverse functions in plant growth and development and contribute to all aspects of plant interactions with their surrounding environment. These compounds protect plants from damaging ultraviolet radiation and reactive oxygen species, provide mechanical support for the plants to stand upright, and mediate plant-plant and plant-microorganism communications. The enormous metabolic diversity of phenylpropanoids is further expanded by chemical modifications known as "decorative reactions", including hydroxylation, methylation, glycosylation, and acylation. Among these modifications, glycosylation is the major driving force of phenylpropanoid structural diversification, also contributing to the expansion of their properties. Phenylpropanoid glycosylation is catalyzed by regioselective uridine diphosphate (UDP)-dependent glycosyltransferases (UGTs), whereas glycosyl hydrolases known as β-glucosidases are the major players in deglycosylation. In this article, we review how the glycosylation process affects key physicochemical properties of phenylpropanoids, such as molecular stability and solubility, as well as metabolite compartmentalization/storage and biological activity/toxicity. We also summarize the recent knowledge on the functional implications of glycosylation of different classes of phenylpropanoid compounds. A balance of glycosylation/deglycosylation might represent an essential molecular mechanism to regulate phenylpropanoid homeostasis, allowing plants to dynamically respond to diverse environmental signals.

Abstract
Alzheimer's disease (AD), also known as senile dementia, is the most common degenerative disease of the central nervous system. Neuroinflammation is currently believed to be a crucial factor in the progression of AD, while its exact mechanism remains unclear. In this study, we demonstrated that AD transgenic mice exhibited cognitive deficits accompanied by the elevated serum and brain inflammation. Treating with a natural active ingredient tetrahydroxy stilbene glucoside (TSG) from the Chinese herb Polygonum multiflorum that has been well known for its unique anti-aging effect, learning-memory ability of AD mice was distinctly improved. Meanwhile, it was observed that the expressions of serum inflammatory cytokines and the activation of microglia in cerebral cortex and hippocampus were suppressed after TSG treatment, which was probably attributable to the decrease of cyclic GMP-AMP synthase (cGAS) and stimulator of interferon genes (STING) triggered immune response and NLRP3 inflammasome activation. Furthermore, cell culture experiments employing LPS combined with IFN-γ induced microglia activation showed that TSG reversed the polarization status of M1-type microglia to restore the quiescence, and cGAS-STING elevation was observed in the activated microglia and normalized by TSG incubation. In addition, TSG suppressed the production of inflammatory cytokines such as IL-1β, IL-6, TNF-α, IFN-α and IFN-β, as well as the expression of IFN regulatory proteins such as IFIT1 and IRF7 in the LPS/IFN-γ-stimulated inflammatory response in BV2 cell. Finally, it was also verified that TSG are, in part, through a cGAS-STING dependent pathway and triggered NLRP3 inflammasome activation to inhibit neuroinflammation through interfering with cGAS-STING inhibitors. Taken together, our findings highlight the health benefits of TSG and its potential application in preventing cognitive disorders by inhibiting neuroinflammation through cGAS-STING signaling pathway in AD.

Abstract
BACKGROUND Alzheimer's disease (AD) is a neurogenerative disease and remains no effective method for stopping its progress. Ferroptosis and adaptive immunity have been proven to contribute to AD pathogenesis. Salidroside exhibits neuroprotective and immunomodulatory effects. However, the underlying mechanisms linking salidroside, ferroptosis, and adaptive immunity in AD remain uncertain. PURPOSE The objective of this study is to explore the neuroprotective effects and the potential molecular mechanisms of salidroside against neuronal ferroptosis and CD8+ T cell infiltration in senescence-accelerated mouse prone 8 (SAMP8) mice. STUDY DESIGN AND METHODS SAMP8 mice were employed as an AD model and were treated with salidroside for 12 weeks. Behavioral tests, immunohistochemistry, HE and Nissl staining, immunofluorescence, transmission electron microscopy, quantitative proteomics, bioinformatic analysis, flow cytometry, iron staining, western blotting, and molecular docking were performed. RESULTS Treatment with salidroside dose-dependently attenuated cognitive impairment, reduced the accumulation of Aβ plaques and restored neuronal damage. Salidroside also suppressed the infiltration of CD8+T cells, oxidative stress, and inflammatory cytokines, and improved mitochondrial metabolism, iron metabolism, lipid metabolism, and redox in the SAMP8 mice brain. The administration of salidroside decreased iron deposition, reduced TFR1, and ACSL4 protein expression, upregulated SLC7A11, and GPX4 protein expression, and promoted the Nrf2/GPX4 axis activation. CONCLUSION In conclusion, neuronal ferroptosis and CD8+T cells are involved in the process of cognitive impairment in SAMP8 mice. Salidroside alleviates cognitive impairment and inhibits neuronal ferroptosis. The underlying mechanisms may involve the Nrf2/GPX4 axis activation and reduction in CD8+T cells infiltration. This study provides some evidence for the roles of salidroside in adaptive immunity and neuronal ferroptosis in SAMP8 mice.

Abstract
Alzheimer’s disease (AD) is a degenerative disease of the central nervous system that is the most common type of senile dementia. Ferroptosis is a new type of iron-dependent programmed cell death identified in recent years that is different from other cell death forms. Ferroptosis is induced by excessive accumulation of lipid peroxides and reactive oxygen species (ROS) in cells. In recent years, it has been found that ferroptosis plays an important role in the pathological process of AD. Iron dyshomeostasis contribute to senile plaques (SP) deposition and neurofibrillary tangles (NFTs). Iron metabolism imbalance in brain and the dysfunction of endogenous antioxidant systems including system Xc- and glutathione peroxidase (GPX) are closely related to the etiopathogenesis of AD. Dysfunction of nuclear receptor coactivator 4 (NCOA4)-mediated ferritinophagy induced ferroptosis can accelerates the pathological process of AD. In addition, NRF2, through regulating the expression of a considerable number of genes related to ferroptosis, including genes related to iron and glutathione metabolism, plays an important role in the development of AD. Here, we review the potential interaction between AD and ferroptosis and the major pathways regulating ferroptosis in AD. We also review the active natural and synthetic compounds such as iron chelators, lipid peroxidation inhibitors and antioxidants available to treat AD by alleviating iron dyshomeostasis and preventing ferroptosis in mice and cell models to provide valuable information for the future treatment and prevention of AD.

Abstract
Polygonum multiflorum Thunb. (He-shou-wu in Chinese), a Chinese botanical drug with a long history, is widely used to treat a variety of chronic diseases in clinic, and has been given the reputation of “rejuvenating and prolonging life” in many places. 2,3,4′,5-tetrahydroxystilbene-2-O-β-D-glucoside (TSG, C20H22O9) is the main and unique active ingredient isolated from Polygonum multiflorum Thunb., which has extensive pharmacological activities. Modern pharmacological studies have confirmed that TSG exhibits significant activities in treating various diseases, including inflammatory diseases, neurodegenerative diseases, cardiovascular diseases, hepatic steatosis, osteoporosis, depression and diabetic nephropathy. Therefore, this review comprehensively summarizes the pharmacological and pharmacokinetic properties of TSG up to 2021 by searching the databases of Web of Science, PubMed, ScienceDirect and CNKI. According to the data, TSG shows remarkable anti-inflammation, antioxidation, neuroprotection, cardiovascular protection, hepatoprotection, anti-osteoporosis, enhancement of memory and anti-aging activities through regulating multiple molecular mechanisms, such as NF-κB, AMPK, PI3K-AKT, JNK, ROS-NO, Bcl-2/Bax/Caspase-3, ERK1/2, TGF-β/Smad, Nrf2, eNOS/NO and SIRT1. In addition, the toxicity and pharmacokinetics of TSG are also discussed in this review, which provided direction and basis for the further development and clinical application of TSG.
