Abstract
BACKGROUND Prostate cancer (PCa) is becoming the most common malignancy in men worldwide. We investigated the effect of astragaloside IV combined with PESV on the gut microbiota and metabolite of PCa mice and the process of treating PCa. METHODS Nude mice were genetically modified to develop tumors characteristic of PCa. The treatment of PCa mice involved the administration of a combination of astragaloside IV and peptides derived from scorpion venom (PESV). Feces were collected for both 16 S rDNA and metabolic analysis. Fecal supernatant was extracted and used for fecal transplantation in PCa mice. Tumor development was observed in both PCa mice and nude mice. Tumor histopathology was examined, and the expression of inflammatory factors and the AGE-RAGE axis in PCa tissues were analyzed. RESULTS PCa mice treated with Astragaloside IV in combination with PESV showed a significant reduction in tumor volume and weight, and stabilization of gut microbiota and metabolites. At the Genus level, significant differences were observed in Porphyromonas, Corynebacterium, Arthromitus and Blautia, and the differential metabolites were PA16_016_0, Astragaloside+, Vitamin A acid, Nardosinone, a-Nortestoster, D-Pantethine, Hypoxanthine, Pregnenolone, cinnamic acid, Pyridoxa, Cirtruline and Xanthurenate. There was a correlation between gut microbiota and metabolites. After the fecal transplantation, tumor growth was effectively suppressed in the PCa mice. Notably, both the mRNA and protein levels of the receptor for advanced glycation end products (RAGE) were significantly decreased. Furthermore, the expression of inflammatory factors, namely NF-κB, TNF-α, and IL-6, in the tumor tissues was significantly attenuated. Conversely, upregulation of RAGE led to increased inflammation and reversed tumor growth in the mice. CONCLUSION Astragaloside IV combined with PESV could treat PCa by intervening in gut microbiota composition and metabolite by targeting RAGE.

Abstract
OBJECTIVE Baicalin (BC) is a flavonoid reported to have various pharmacological activities, including antioxidant, anti-cancer, anti-inflammatory, anti-allergy, immune regulation, and anti-diabetic. This study examines the probable mechanism for gestational diabetes mellitus (GDM) brought on by streptozotocin (STZ) and the impact of BC on fetal development via AGEs (advanced serum glycation end products) and RAGE (the role of advanced glycation end products). MATERIAL AND METHOD STZ has been used in the current experimental study to induce diabetes mellitus in pregnant animals (gestational diabetes mellitus). GDM pregnant animals were separated into five groups and were treated with BC in a dose-dependent pattern for 19 days. At the end of the experiment, the fetus and blood samples were drawn from all the pregnant rats to assess the biochemical parameter as well as AGE-RAGE. RESULT Administration of BC at varying doses leads to enhancement in the weight of the fetus body and placenta while gestational diabetic pregnant animals induced by STZ had a lower weight of the fetus body and placenta. The dose-dependent pattern of BC also enhanced fasting insulin (FINS), high-density lipoprotein (HDL), serum insulin, and hepatic glycogen. It also significantly enhanced the content of the antioxidant profile and pro-inflammatory cytokines and modulated the gene expression (VCAM- 1, p65, EGFR, MCP-1, 1NOX2, and RAGE) in various tissues in gestational diabetes mellitus pregnant rats. CONCLUSION Baicalin demonstrated the potential impact on the embryo's development via the AGE-RAGE signaling pathway in STZ-induced GDM pregnant animals.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gleditsiae sinensis fructus Pills (GF) is a famous classical prescription, that is regularly combined with Jujubae fructus (JF) for the treatment of chronic bronchitis (CB) in the clinic. While the clinical efficacy of this combination prescription is clearly established, the active ingredients and molecular mechanisms remain unclear. AIM OF THE STUDY To elucidate the mechanisms of action of Gleditsiae sinensis fructus Pills combined with Jujubae fructus (GF&JF) against CB based on network pharmacology and experimental verification. MATERIALS AND METHODS The potential targets of GF&JF involved in therapeutic activity against CB were predicted based on network pharmacology and an "ingredients-targets" network constructed. The Metascape database was used for Module, GO functional and KEGG signaling pathway enrichment analyses of potential targets. Molecular docking was applied to simulate the binding activities of key candidate active ingredients to core targets. For experimental verification, a CB model was established through smoking and nasal cavity drip of lipopolysaccharide. Related inflammatory factors, including TNF-α, TGF-β, IL-6 and IL-8 in serum, and IL-4 IL-8, IFN-γ and IL-10 in bronchoalveolar lavage fluid (BALF), were detected using ELISA. Hematoxylin and eosin (H&E) and Masson staining were performed to observe pathological changes in lung and tracheal tissue. The expression of related proteins and mRNAs in the lung tissue were detected using immunohistochemistry (IHC), quantitative real-time PCR, and western blot. RESULTS In network pharmacology, 36 common targets of GF&JF for CB were screened and the key targets and main signaling pathways identified. The active ingredients quercetin and stigmasterol in GF&JF had more targets for CB, which displayed good binding activity to IL-6, VEGFA, and EGFR, as established from molecular docking results. In vivo, GF&JF effectively inhibit the inflammatory response in CB mice and improved pathological changes in lung and tracheal tissue. In terms of the key proteins of the AGE-RAGE signaling pathway, GF&JF induced significant down-regulation of IL-6, ICAM-1, VCAM-1, EGFR, CASPASE-3, AGEs and RAGE proteins in lung tissue as well as mRNA expression of IL-6, ICAM-1, VCAM-1, EGFR, AGEs and RAGE. CONCLUSIONS The GF&JF combination exerts a good therapeutic effect in CB model mice, which may be attributed to inhibition of the inflammatory response as well as regulation on the expression of AGE-RAGE signaling pathway. In addition, quercetin and stigmasterol appear to be the main active ingredients of GF&JF in the treatment of CB.

Abstract
Cannabidiol (CBD), the most abundant nonpsychoactive constituent of Cannabis sativa plant, is a promising potential pharmacotherapy for the treatment of diabetes and associated comorbidities. Previous studies have shown the potential of CBD to prevent diabetes in mice, the precise mechanisms of action remain unclear. The purpose of this study was to explore the mechanism of CBD alleviating hyperglycemia. The results demonstrated that CBD reduced blood glucose of STZ-induced diabetic mice without causing hypoglycemia. To elucidate the possible mechanisms of CBD effect, RNA-seq analysis was performed on high glucose-induced human mesangial cells (HMCs). By cluster analysis of differential genes, the results showed that advanced glycation end products-receptor of advanced glycation endproducts (AGE-RAGE) pathway-related genes CCL2 and interleukin-1β (IL-1β) play an important role in the biological of CBD. The expression of CCL2 and IL-1β were significantly increased in HMCs. Whereas, treatment with CBD decreased the expression of CCL2 and IL-1β. In addition, CBD significantly reduced AGE-RAGE levels in high glucose-induced HMCs. Similar results were confirmed in diabetic mice. In conclusion, we discovered for the first time that CBD ameliorates hyperglycemia partly through AGE-RAGE mediated CCL2/IL-1β pathway.

Abstract
BACKGROUND Fuzi-Gancao herb couple is one of the most common herb couples involved in the TCM formula, which was used for the treatment of chronic diseases. The herb couple has a hepatoprotective effect. However, its main components and therapeutic mechanism are not yet clear. This study aims to elucidate the therapeutic effect and mechanism of the Fuzi-Gancao herb couple on NAFLD from animal experiments, network pharmacology, and molecular docking. METHODS 60 Male C57BL/6 mice (20 g ± 2 g) were randomly divided into six groups including the blank group (n=10) and NALFD group (n=50). The mice of the NALFD group were fed with a high-fat diet for 20 weeks to establish the NAFLD model and the NALFD mice were randomly divided into five groups including positive group (berberine), model group and F-G groups with three dosages (0.257, 0.514, 0.771 g/kg) (n=10). After 10 weeks of administration, the serum was collected for the analysis of ALT, AST, LDL-c, HDL-c, and TC, and liver tissues were collected for pathological analysis. The TCMAS database was used to collect the main components and targets of the Fuzi-Gancao herb couple. The GeneCards database was used to collect NAFLD-related targets, and the key targets were obtained by intersecting with herbal targets. The disease-component-target relationship diagram was constructed by Cytoscape 3.9.1. The obtained key targets were imported into the String database to obtain the PPI network, and imported into the DAVID database for KEGG pathway analysis and GO analysis. Finally, the key targets and key gene proteins were imported into Discovery Studio 2019 for molecular docking verification. RESULTS In this study, H-E staining indicated the pathological changes of liver tissue in Fuzi-Gancao groups were significantly improved, and the levels of AST, ALT, TC, HDL-c, and LDL-c in serum of Fuzi-Gancao groups decreased in a dose-dependent manner, compared with the model group. 103 active components and 299 targets in the Fuzi-Gancao herb couple were confirmed in the TCMSP database and 2062 disease targets in NAFLD were obtained. 142 key targets and 167 signal pathways were screened, such as the AGE-RAGE signaling pathway in diabetic complications, HIF-1 signaling pathway, IL-17 signaling pathway, TNF signaling pathway, and so on. The main bioactive ingredients of Fuzi-Gancao herb couple in the treatment of NAFLD are quercetin, kaempferol, naringenin, inermine, (R)-norcoclaurine, isorhamnetin, ignavine, 2,7-Dideacetyl-2,7-dibenzoyl-taxayunnanine F, glycyrol mainly involving IL6, AKT1, TNF, TP53, IL1B, VEGFA and other core targets. Molecular docking analysis indicated that there is a good affinity between the key components and the key targets. CONCLUSION This study preliminarily explained the main components and mechanism of the Fuzi-Gancao herb couple in the treatment of NAFLD and provided an idea for subsequent research.

Abstract
PURPOSE Type 2 diabetic (T2D) patients have liver and adipose tissue microcirculation disturbances associated with metabolic dysfunction and disease progression. However, the potential role of aerobic training on hepatic and white adipose tissue (WAT) microcirculation and the underlying mechanisms have not been elucidated to date. Therefore, we investigated the role of aerobic training on liver and WAT microcirculation and AGE-RAGE modulation in T2D mice. METHODS The control group (CTL) was fed standard chow, and T2D was induced by feeding male C57BL/6 a high-fat, high-carbohydrate diet for 24 weeks. In the following 12 weeks, mice underwent aerobic training (CTL EX and T2D EX groups), or were kept sedentary (CTL and T2D groups). We assessed metabolic parameters, biochemical markers, oxidative damage, the AGE-RAGE axis, hepatic steatosis, hepatic stellate cells activation (HSC) and liver and WAT microcirculation. RESULTS Hepatic microcirculation was improved in T2D EX mice which were associated with improvements in body, liver and fat mass, blood pressure, hepatic steatosis and fibrosis, and decreased HSC and AGE-RAGE activation. In contrast, improvement in WAT microcirculation, that is, decreased leukocyte recruitment and increased perfusion, was associated with increased catalase antioxidant activity. CONCLUSION Physical training improves hepatic and adipose tissue microcirculatory dysfunction associated with T2D, likely due to downregulation of AGE-RAGE axis, decreased HSC activation and increased antioxidant activity.

Abstract
One of the proposed mechanisms for the development of diabetic nephropathy (DN) is the increase of end products of advanced glycosylation (AGEs), which bind to its receptor (RAGE), favoring nephron cellular damage. An isoform of this receptor is soluble RAGE (sRAGE), which can antagonize AGE-altered intracellular signaling. It has known that green tea extract (GTE) increases the expression of sRAGE, but it is unknown whether this could improve kidney function. The objective of this study was to evaluate the effect of the administration of GTE on the concentrations of sRAGE, renal function, and metabolic profile in patients with type 2 diabetes mellitus (T2DM) and DN. A randomized, double-blinded, placebo-controlled clinical trial was carried out in 39 patients who received GTE (400 mg every 12 h) or placebo for 3 months. sRAGE levels, renal function, and metabolic parameters were determined before and after the intervention. In the GTE group, there were statistically significant increase on sRAGE (320.55 ± 157.63 pg/mL vs. 357.59 ± 144.99 pg/mL; P = .04) and glomerular filtration rate (GFR; 66.44 ± 15.17 mL/min/1.73 m2 vs. 71.70 ± 19.33 mL/min/1.73 m2; P = .04), and a statistically significant decrease in fasting serum glucose (7.62 ± 3.00 mmol/L vs. 5.86 ± 1.36 mmol/L; P ≤ .01) and triacylglycerols (1.91 ± 0.76 mmol/L vs. 1.58 ± 0.69; P = .02). Administration of GTE increases the serum concentration of sRAGE and the GFR and decreases the concentration of fasting serum glucose and triacylglycerols. The study was registered in ClinicalTrials.gov with the identifier NCT03622762.

Abstract
Stroke is one of the leading causes of death worldwide. Hemorrhagic transformation (HT) is a common serious complication of ischemic stroke (IS) and is related to poor prognosis. Hyperglycemia after stroke is associated with the occurrence of HT and seriously affects the clinical treatment of stroke. Our previous experiments demonstrated that the Xiao-Xu-Ming decoction effective components group (XXMD), which is a Chinese medicine formula reconstituted by active ingredients, has multiple pharmacological effects in the treatment of IS. However, the effects of XXMD on HT after IS remain unclear. Thus, we investigated the preventive effects of XXMD on hyperglycemia-induced HT and further explored the underlying mechanism. Acute hyperglycemia combined with the electrocoagulation cerebral ischemia model was used to establish the HT model. XXMD (37.5, 75, 150 mg/kg/d) was given by gavage for 5 days. Network pharmacology was used to predict potential targets and pathways of XXMD in HT occurrence, and further studies confirmed the related targets. The results showed that hyperglycemia aggravated neurological deficits and blood-brain barrier (BBB) disruption, leading to intracerebral hemorrhage. Pretreatment with XXMD improved neurological function and BBB integrity and inhibited HT occurrence. Network pharmacology revealed that AGE-RAGE-mediated neuroinflammation may be associated with hyperglycemia-induced HT. Further studies confirmed that hyperglycemia activated the AGE-RAGE signaling pathway, increased the expression of HMGB1, TLR4 and p-p65, and induced the release of inflammatory factors and neutrophil infiltration, leading to HT. XXMD could inhibit AGE-RAGE-mediated neuroinflammation. These findings indicated that pretreatment with XXMD alleviated hyperglycemia-induced HT, which may be associated with the inhibition of AGE-RAGE-mediated neuroinflammation. Therefore, XXMD may be a potential therapeutic drug for HT.

Abstract
This work explored influences of protocatechuic acid (PCA) on type 2 diabetes (T2D)-associated hepatic insulin resistance and other metabolic, hepatic and vascular irregularities using the rat model of high fat diet (HFD)+high fructose+low dose streptozotocin (STZ). Twenty-four male Wister rats were used. Twelve rats were ad libitum supplied with HFD and high fructose drinking water (25 % w/v) for 60 days. On day 30, they received a single injection of STZ (35 mg/kg, i.p). On day 32, they were divided into two subgroups (n = 6/each): T2D + PCA, received PCA (100 mg/kg/day, orally) and T2D, received PCA vehicle till the end of experiment. Rats provided with regular diet and fructose-free drinking water, with or without PCA treatment, served as PCA and control groups (n = 6/each), respectively. PCA treatment significantly reduced the elevated levels of fasting glycemia and insulin, AUCOGTT, AUCITT, and HOMA-IR index, while it boosted HOMA-β and insulinogenic index values in T2D rats. PCA ameliorated serum lipid levels and hepatic function parameters and mitigated hepatosteatosis in T2D rats. Mechanistically, PCA mitigated hepatic lipid peroxidation and restored reduced glutathione (GSH) and superoxide dismutase (SOD) to near-normal levels. Moreover, PCA enhanced hepatic protein levels of P-AKTser473 and hepatic mRNA expression of insulin receptor substrate 1 (IRS1), phosphatidylinositol 3 kinase (PI3K)-p85 and AKT2. Furthermore, PCA ameliorated aortic oxidative stress in T2D rats, possibly via reducing serum levels of advanced glycation end products (AGEs) and diminishing vascular expression of RAGE and NOX4 mRNA. Collectively, PCA may improve hepatic insulin resistance and vascular oxidative status by modulating IRS1/PI3K/AKT2 and AGE-RAGE-NOX4 pathways, respectively.

Abstract
This study aimed to elucidate the key mechanisms and effects of the functional component of green tea, epigallocatechin gallate (EGCG) on a diabetic mouse model. The detected relationship between compounds and genes recorded in the STITCH database highlighted an interaction network between the direct target genes of EGCG and the known diabetes-related genes, which was made apparent through the analysis of gene-gene interactions and signaling pathways, revealing that a key AGE-RAGE signaling pathway in diabetes was enriched in the network. By means of systematic supplementary analyses on diabetic mice, provided evidence suggested that EGCG could significantly enhance the morphology of pancreatic tissues in diabetic mice and downregulate the blood glucose level in a clear dose effect manner, and increased insulin receptor (IR), insulin receptor substrate (IRS1 and IRS2) expression in the liver. Through the detection of protein expression, EGCG was observed to possess the ability to downregulate the accumulation of AGE-RAGE in pancreatic tissues as well as in the transcription factor nuclear factor-κB (NF-κB), which represents a potentially significant method by which EGCG influences diabetes. The results of this study provided evidence indicating that EGCG can effectively improve the morphology of pancreatic tissues, but notably reduce blood glucose levels in diabetic mice, which may be related to its inhibition of AGE-RAGE signaling pathway and activation of transcription factor NF-κB pathway.

Abstract
Dendritic cells (DCs) are critical antigen-presenting cells which are the initiators and regulators of the immune response. Numerous studies support the idea that dietary sugars influence DC functions. Increased consumption of fructose has been thought to be the leading cause of metabolic disorders. Although evidence supports their association with immune dysfunction, the specific mechanisms are not well understood. Fructose is one of the main dietary sugars in our diet. Therefore, here we compared the effect of fructose and glucose on the functions of human DCs. High levels of D-fructose compared to D-glucose led to activation of DCs in vitro by promoting interleukin (IL)-6 and IL-1β production. Moreover, fructose exposed DCs also induced interferon (IFN)-γ secretion from T cells. Proinflammatory response of DCs in high fructose environment was found to be independent of the major known metabolic regulators or glycolytic control. Instead, DC activation on acute exposure to fructose was via activation of receptor for advanced glycation end product (RAGE) in response to increased accumulation of advanced glycation end products (AGE). However, chronic exposure of DCs to high fructose environment induced a shift towards glycolysis compared to glucose cultured DCs. Further investigations revealed that the AGEs formed by fructose induced increased levels of inflammatory cytokines in DCs compared to AGEs from glucose. In summary, understanding the link between metabolic changes and fructose-induced DC activation compared to glucose has broad implications for immune dysfunction associated with metabolic disorders.

Abstract
Background Inflammation is generally suppressed during hibernation, but select tissues (e.g. lung) have been shown to activate both antioxidant and pro-inflammatory pathways, particularly during arousal from torpor when breathing rates increase and oxidative metabolism fueling the rewarming process produces more reactive oxygen species. Brown and white adipose tissues are now understood to be major hubs for the regulation of immune and inflammatory responses, yet how these potentially damaging processes are regulated by fat tissues during hibernation has hardly been studied. The advanced glycation end-product receptor (RAGE) can induce pro-inflammatory responses when bound by AGEs (which are glycated and oxidized proteins, lipids, or nucleic acids) or damage associated molecular pattern molecules (DAMPs, which are released from dying cells). Methods Since gene expression and protein synthesis are largely suppressed during torpor, increases in AGE-RAGE pathway proteins relative to a euthermic control could suggest some role for these pro-inflammatory mediators during hibernation. This study determined how the pro-inflammatory AGE-RAGE signaling pathway is regulated at six major time points of the torpor-arousal cycle in brown and white adipose from a model hibernator, Ictidomys tridecemlineatus. Immunoblotting, RT-qPCR, and a competitive ELISA were used to assess the relative gene expression and protein levels of key regulators of the AGE-RAGE pathway during a hibernation bout. Results The results of this study revealed that RAGE is upregulated as animals arouse from torpor in both types of fat, but AGE and DAMP levels either remain unchanged or decrease. Downstream of the AGE-RAGE cascade, nfat5 was more highly expressed during arousal in brown adipose. Discussion An increase in RAGE protein levels and elevated mRNA levels of the downstream transcription factor nfat5 during arousal suggest the pro-inflammatory response is upregulated in adipose tissue of the hibernating ground squirrel. It is unlikely that this cascade is activated by AGEs or DAMPs. This research sheds light on how a fat-but-fit organism with highly regulated metabolism may control the pro-inflammatory AGE-RAGE pathway, a signaling cascade that is often dysregulated in other obese organisms.

Abstract
There is growing evidence that chronic hyperglycemia leads to the formation of advanced glycation end products (AGEs) which exerts its effect via interaction with the receptor for advanced glycation end products (RAGE). AGE-RAGE activation results in oxidative stress and inflammation. It is well known that this mechanism is involved in the pathogenesis of cardiovascular disease in diabetes. Kaempferol, a dietary flavonoid, is known to possess antioxidant, anti-apoptotic, and anti-inflammatory activities. However, little is known about the effect of kaempferol on myocardial ischemia-reperfusion (IR) injury in diabetic rats. Diabetes was induced in male albino Wistar rats using streptozotocin (70 mg/kg; i.p.), and rats with glucose level >250 mg/dL were considered as diabetic. Diabetic rats were treated with vehicle (2 mL/kg; i.p.) and kaempferol (20 mg/kg; i.p.) daily for a period of 28 days and on the 28th day, ischemia was produced by one-stage ligation of the left anterior descending coronary artery for 45 min followed by reperfusion for 60 min. After completion of surgery, rats were sacrificed and the heart tissue was processed for biochemical, morphological, and molecular studies. Kaempferol pretreatment significantly reduced hyperglycemia, maintained hemodynamic function, suppressed AGE-RAGE axis activation, normalized oxidative stress, and preserved morphological alterations. In addition, there was decreased level of inflammatory markers (tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and NF-κB), inhibition of active c-Jun N-terminal kinase (JNK) and p38 proteins, and activation of Extracellular signal regulated kinase 1/2 (ERK1/2) a prosurvival kinase. Furthermore, it also attenuated apoptosis by reducing the expression of pro-apoptotic proteins (Bax and Caspase-3), Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) positive cells, and increasing the level of anti-apoptotic protein (Bcl-2). In conclusion, kaempferol attenuated myocardial ischemia-reperfusion injury in diabetic rats by reducing AGE-RAGE/ mitogen activated protein kinase (MAPK) induced oxidative stress and inflammation.
