Pancreatic β-cell apoptosis caused by apolipoprotein C3-rich low-density lipoprotein is attenuated by kansuinine A through oxidative stress inhibition

Dyslipidemia exacerbates pancreatic β-cell apoptosis, heightening the risk of type 2 diabetes (T2DM). Kansuinine A (KA), a diterpene from Euphorbia roots, exhibits antiapoptotic properties, suggestive of its therapeutic potential against T2DM. In this study, we evaluated the protective effects of KA against apolipoprotein C3 (ApoC3)-rich low-density lipoprotein (LDL) (AC3RL)-induced β-cell apoptosis and its underlying mechanism of action. ApoE-/- mice fed a high-fat diet and treated with KA demonstrated improved glucose and insulin tolerance, enhanced antioxidant capacity, and reduced pancreatic β-cell apoptosis. In rat pancreatic β-cells (RIN-m5F) exposed to AC3RL, KA significantly improved cell viability, suppressed oxidative stress, and mitigated apoptosis by downregulating lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) expression and inhibiting the IκB kinase β (IKKβ)/Inhibitor of κB alpha (IκB⍺)/Nuclear Factor kappa B(NF-κB) signaling pathway. Molecular docking and pathway analyses revealed the interactions of KA with key targets involved in oxidative stress and apoptosis. These findings highlight the ability of KA to counteract AC3RL-induced β-cell dysfunction, offering promise as a potential intervention for dyslipidemia-driven diabetes.

Ginseng in delaying brain aging: Progress and Perspectives

BACKGROUND

The Shennong Bencao Jing (Shennong's Classic of Materia Medica) records that Panax ginseng C. A. Mey (ginseng) 'lightens the body and prolongs life'. Many investigations have documented that ginseng exerts neuroprotective effects by mitigating the aging of the brain. However, a comprehensive review of the impacts of ginseng on brain aging remains lacking.

PURPOSE

This study aims to review the advances in ginseng research regarding its role in delaying brain aging, focusing on its bioactive constituents, underlying mechanisms and potential side effects. The findings provide scientific pieces of evidence to support the medical utilization of ginseng in the delaying senescence and the management of aging-related diseases.

METHODS

This review includes studies on ginseng and brain aging in humans, retrieved from English-language research articles published between 2017 and the present in the PubMed and Web of Science databases. The work focused on ginseng, brain aging, and aging-related diseases, utilizing keywords such as "Ginseng", "Brain aging", "central nervous system", "intracellular homeostasis", "peripheral system", etc. RESULTS: Ginseng comprises a varied spectrum of biologically bioactive constituents, such as ginsenosides, Maillard reaction products, ginseng polysaccharides, volatile oils, amino acids, proteins, etc. These components work to contribute to their significant medicinal value. Based on the traditional Chinese medicine (TCM) theory that "the heart and brain are interconnected, the liver and brain are mutually supportive, the brain and spleen are related, the brain and lung are linked, and the brain and kidney work in harmony," we summarize that ginseng may sustain neural homeostasis through both central and peripheral perspectives. Additionally, the potential toxic side effects of ginseng are minimal.

CONCLUSION

Ginseng and its bioactive constituents exhibit considerable promise in delaying brain aging and treating neurodegenerative diseases. Future research should prioritize exploring the direct targets of ginseng and its active ingredients, and work toward establishing precise drug-target-efficacy relationships. This approach will facilitate the translation of these findings into clinically viable therapeutic approaches.

Ginsenoside, a potential natural product against liver diseases: a comprehensive review from molecular mechanisms to application

Liver disease constitutes a significant cause of global mortality, with its pathogenesis being multifaceted. Identifying effective pharmacological and preventive strategies is imperative for liver protection. Ginsenosides, the major bioactive compounds found in ginseng, exhibit multiple pharmacological activities including protection against liver-related diseases by mitigating liver fat accumulation and inflammation, preventing hepatic fibrosis, and exerting anti-hepatocarcinogenic effects. However, a comprehensive overview elucidating the regulatory pathways associated with ginsenosides in liver disease remains elusive. This review aims to consolidate the molecular mechanisms through which different ginsenosides ameliorate distinct liver diseases, alongside the pathogenic factors underlying liver ailments. Notably, ginsenosides Rb1 and Rg1 demonstrate significantly effective in treating fatty liver, hepatitis, and liver fibrosis, and ginsenosides CK and Rh2 exhibit potent anti-hepatocellular carcinogenic effects. Their molecular mechanisms underlying these effects primarily involve the modulation of AMPK, NF-κB, TGF-β, NFR2, JNK, and other pathways, thereby attenuating hepatic fat accumulation, inflammation, inhibition of hepatic stellate cell activation, and promoting apoptosis in hepatocellular carcinoma cells. Furthermore, it provides insights into the safety profile and current applications of ginsenosides, thereby facilitating their clinical development. Consequently, ginsenosides present promising prospects for liver disease management, underscoring their potential as valuable therapeutic agents in this context.

A Review of the Therapeutic Potential of Ginseng and Its Bioactive Components in Nonalcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease (NAFLD) is the major cause of chronic liver disease worldwide, with no universally recognized effective treatments currently available. In recent years, ginseng and its principal active components, such as ginsenosides, have shown potential protective effects in the treatment of these liver diseases. In NAFLD, studies have demonstrated that ginseng can improve hepatic lipid metabolism, reduce inflammatory responses, and inhibit oxidative stress and fibrosis, thereby attenuating the progression of NAFLD. Additionally, ginseng inhibits oxidative stress by scavenging free radicals and enhancing antioxidant enzyme activities, and it can impede fibrosis by interfering with the fibrotic signaling pathways. These combined effects contribute to attenuating the progression of NAFLD. These findings highlight the promise of ginseng as a potential therapeutic candidate for the treatment of NAFLD. However, despite the significant efficacy of ginseng in human NAFLD treatment, the number and quality of clinical studies remain limited, with a lack of large-scale, multicenter clinical trials to confirm these effects. Moreover, the pharmacokinetic properties of different ginsenosides, optimal therapeutic dosages, and the safety of long-term use require further investigation. This review summarizes the existing evidence on the mechanisms of action of ginseng and its active components in human NAFLD, assesses their potential as therapeutic options, and proposes future research directions to provide stronger scientific support for clinical application. Additionally, we performed a network pharmacology analysis of ginseng in relation to NAFLD to identify and investigate potential targets of ginseng in the treatment of NAFLD. This analysis aims to provide a theoretical foundation for the development of ginseng -based drugs for combating NAFLD.

Bioinformatics study of the potential therapeutic effects of ginsenoside Rh3 in reversing insulin resistance

Background

In recent years, the incidence of insulin resistance is increasing, and it can cause a variety of Metabolic syndrome. Ginsenosides have been clinically proven to improve fat metabolism and reduce insulin resistance, but their components and mechanism of action are still unclear.

Objective

Ginsenoside, a bioactive compound derived from ginseng, exhibits significant potential in treating obesity, diabetes, and metabolic disorders. Despite evidence supporting its efficacy in ameliorating insulin resistance (IR) in obesity, the specific bioactive components and underlying mechanisms remain obscure. In this study, we endeavored to elucidate the potential molecular targets and pathways influenced by ginsenoside Rh3 (GRh3) to ameliorate IR in liver tissue. We employed a comprehensive approach that integrates system pharmacology and bioinformatics analysis.

Materials and methods

Our methodology involved the identification of candidate targets for GRh3 and the profiling of differentially expressed genes (DEGs) related to IR in individuals with insulin resistance. The coalescence of candidate targets and DEGs facilitated the construction of a "GRh3-targets-disease" network for each tissue type, ultimately yielding 38 shared target genes. Subsequently, we conducted pathway enrichment analysis, established protein-protein interaction (PPI) networks, and identified hub targets among the GRh3 targets and IR-related DEGs. Additionally, we conducted animal experiments to corroborate the role of these hub targets in the context of GRh3.

Results

Our investigation identified a total of 38 overlapping targets as potential candidates. Notably, our analysis revealed crucial hub targets such as EGFR, SRC, ESR1, MAPK1, and CASP3, alongside implicated signaling pathways, including those related to insulin resistance, the FoxO signaling pathway, the PPAR signaling pathway, and the IL-17 signaling pathway. This study establishes a robust foundation for the mechanisms underlying GRh3's efficacy in mitigating IR. Furthermore, these results suggest that GRh3 may serve as a representative compound within the ginsenoside family.

Conclusion

This study elucidates the potential molecular targets and associated pathways through which GRh3 ameliorates IR, showcasing its multifaceted nature, spanning multiple targets, pathways, and mechanisms. These findings establish a robust foundation for subsequent experimental inquiries and clinical applications.

Effects of plant natural products on metabolic-associated fatty liver disease and the underlying mechanisms: a narrative review with a focus on the modulation of the gut microbiota

Metabolic-associated fatty liver disease (MAFLD) is a chronic liver disease characterized by the excessive accumulation of fat in hepatocytes. However, due to the complex pathogenesis of MAFLD, there are no officially approved drugs for treatment. Therefore, there is an urgent need to find safe and effective anti-MAFLD drugs. Recently, the relationship between the gut microbiota and MAFLD has been widely recognized, and treating MAFLD by regulating the gut microbiota may be a new therapeutic strategy. Natural products, especially plant natural products, have attracted much attention in the treatment of MAFLD due to their multiple targets and pathways and few side effects. Moreover, the structure and function of the gut microbiota can be influenced by exposure to plant natural products. However, the effects of plant natural products on MAFLD through targeting of the gut microbiota and the underlying mechanisms are poorly understood. Based on the above information and to address the potential therapeutic role of plant natural products in MAFLD, we systematically summarize the effects and mechanisms of action of plant natural products in the prevention and treatment of MAFLD through targeting of the gut microbiota. This narrative review provides feasible ideas for further exploration of safer and more effective natural drugs for the prevention and treatment of MAFLD.
