文摘Emerging evidence highlights the potential of bioactive compounds,particularly polyphenols,as adjunctive therapeutic agents in the treatment of pancreatic cancer(PC),one of the most aggressive malignancies.This review focuses on epigallocatechin gallate(EGCG)and resveratrol due to their extensively documented anticancer activity,favorable safety profiles,and their unique ability to modulate multiple signaling pathways relevant to pan-creatic tumorigenesis.Among polyphenols,these two have shown superior anti-cancer activity,epigenetic regulatory effects,and synergy with standard chemotherapies in preclinical pancreatic cancer models.Resveratrol exhibits anti-proliferative effects by modulating key signaling pathways,including phosphatidylinositol 3 kinase(PI3K)/protein kinase B(Akt),nuclear factor kappa-B(NF-κB),and tumor protein 53(p53).EGCG exerts anti-cancer activity by targeting multiple cellular processes,such as oxidative stress reduction,and suppression of inflammatory mediators like Interleukin-6(IL-6)and Tumor Necrosis Factor-α(TNF-α).Both EGCG and resveratrol exert anti-pancreatic cancer effects partly through direct interactions with cell surface receptors and modulation of intracellular cascades.EGCG targets the 67 kDa laminin receptor(67LR),which is overexpressed in pancreatic cancer cells,triggering apoptosis,cyclic guanosine monophosphate(cGMP)production and activation of the PKCδ/acid sphingomyelinase(ASM)cascade.Resveratrol inhibits insulin-like growth factor-1 receptor(IGF-1R)activation of the PI3K/Akt and Wnt signaling pathways,while concurrently activating tumor suppressor p53.These interactions suppress proliferation,promote apoptosis,and reduce epithelial-mesenchymal transition(EMT),thereby limiting tumor progression.Both polyphenols enhance chemosensitivity and reduce resistance to conventional therapies,including gemcitabine,by modulating drug transporters and apoptotic pathways.Furthermore,their epigenetic influence,particularly via DNA methylation and histone modification,suggests a broader role in pancreatic cancer prevention.Understanding the roles and mechanisms of resveratrol and EGCG in pancreatic cancer provides valuable insights into novel treatment strategies.The integration of polyphenols into conventional therapeutic approaches may offer new hope for improving patient outcomes.

文摘Gut microbiota regulate the activation of adipose browning,which promote energy dissipation and combat diet-induced obesity.Pomegranate peel polyphenols(PPPs)have been shown to reduce obesity,regulate lipid metabolism in adipose tissue,and modulate the composition of gut microbiota in animal fed high-fat diet(HFD).However,the role of gut microbiota in the improvement of obesity by PPPs has not been elucidated.In current study,we applied antibiotics to inhibit gut microbiota in mice fed HFD and treated with PPPs.The results showed that the inhibition of gut microbiota impair the effect of PPPs on reducing obesity and promoting adipose browning,and change the fecal metabolomic profiles in respond to PPPs.Moreover,the inhibition of gut microbiota supressed the promotive effects of PPPs on the levels of Akkermansia and microbiota-related metabolites,such as urolithin A,short-chain fatty acids(SCFAs),and bile acids(BAs),which were associated with activating adipose browning.Therefore,our results suggested that the presence of gut microbiota is essential for PPPs to ameliorate HFD-induced obesity.The related bacteria or metabolites generated by the interaction between PPPs and microbiota promote adipose browning and facilitate the beneficial effects of PPPs.

文摘The aim of this study was to explore the mechanism of action of sea buckthorn polyphenols in the treatment of hyperlipidemia through network pharmacology and molecular docking.The TCMSP pharmacology database was used to screen the polyphenols present in sea buckthorn,and then the SwissTargetPrediction and Uniprot databases were used to obtain the potential targets of sea buckthorn polyphenols,which were supplemented by the literature.In total,7 polyphenols and 154 potential targets were obtained.Through GeneCards,OMIM database,1358 hyperlipidemia-related targets were collected.We found that there were 101 targets at the intersection of components and diseases.Through GO and KEGG enrichment analysis,27 core targets were obtained,which were AKT1,TNF,TP53,IL-6,etc.in order of degree value.174 pathways were obtained from KEGG enrichment analysis,including AGE-RAGE signaling pathway in diabetic complications,fl uid shear stress and atherosclerosis,lipid and atherosclerosis,etc.The molecular docking of the main components to the targets was performed using OpenBabelGUI,AutoDockTools-1.5.6 software.Finally,the results were visualized using Cytoscape 3.9.1 software.The molecular docking results showed that sea buckthorn polyphenols have good binding ability with the key targets.Among them,such as quercetin and kaempferol,have good binding ability with TNF,TP53 and IL-6.For example,TNF binds to quercetin with a binding energy of-5.34 kcal/mol and to kaempferol with a binding energy of-6.22 kcal/mol;TP53 binds to kaempferol with a binding energy of-5.32 kcal/mol;IL-6 binds to quercetin with a binding energy of-5.62 kcal/mol,etc.Therefore,the network pharmacology study showed that the treatment of hyperlipidemia by sea buckthorn polyphenols can be realized by multi-component-multi-target-multi-pathway together,which provides some reference for the later study of sea buckthorn polyphenols in the treatment of hyperlipidemia.

文摘[Objective] The aim was to study the antioxidant effect of polyphenols from pomegranate peel in vivo. [Method] The Kunming rats were randomly divided into a control group, a low-dose group, a middle-dose group and a high-dose group,n=10; the protein content, the activities of the superoxide dismutase（SOD） and the glutathione peroxidase（GSH-PX）, the content of the maleic dialdehyde（MDA） in serum and liver tissue of the rats from different groups were determined. [Result]The polyphenols of pomegranate peel could increase protein content, activities of superoxide dismutase（SOD） and glutathione peroxidase（GSH-PX） in serum and liver tissue, and decrease the maleic dialdehyde（MDA） content simultaneously. [Conclusion] Polyphenols of pomegranate peel have strong antioxidant activity in vivo.
