To investigate the effects of AdipoRon on fatty liver syndrome (FLS) in chicken, we used a corticosterone (CORT)-induced fatty liver model in Cobb broilers in vivo and fat emulsion-induced model in Leghorn male hepatoma cells (LMH) in vitro. In the in vivo study, eighteen 33-day-old male Cobb broilers were randomly assigned to three groups: control group (CONT, vehicle), corticosterone-treated group (CORT, 4 mg/kg), and corticosterone with AdipoRon-treated group (CORT-AR, 4 mg/kg and 0.2 mg/kg, 1 time/1 day) for 5 days. The results showed AdipoRon reduced CORT-induced increase in liver crude fat content (p < 0.05), increased protein expressions of peroxisome proliferator-activated receptor α (PPARα) (p < 0.05) and adiponectin (ADPN) (p < 0.05), and suppressed the protein expressions of Acetyl-CoA carboxylase 1 (ACC) (p < 0.05) and phosphorylated c-Jun N-terminal kinase 1 (p-JNK1) (p < 0.05) in the liver. In the in vitro study, LMH cells were divided into control (CN), fat emulsion (FE, 10%), and FE + AdipoRon (4 μM) group (FE-AR). AdipoRon reduced FE-induced lipid accumulation (p < 0.05), decreased the protein expression of ACC and tumor necrosis factor-alpha (TNF-α), and enhanced PPARα, the phosphorylation of adenosine 5′-monophosphate-activated protein kinase (AMPK), and carnitine palmitoyl transferase 1 (CPT-1) (p < 0.05). In conclusion, AdipoRon effectively reduces hepatic lipid deposition in CORT-induced FLS broilers, likely through PPARα activation and inhibition of lipid synthesis via ACC downregulation.

As Type 2 Diabetes Mellitus (T2DM) has become one of the most severe public health burdens worldwide, it is of great importance to realize early screening and sensitive diagnosis. Adiponectin is widely recognized as a prominent biomarker of T2DM, which holds superior accuracy and sensitivity for early diagnosis owing to its inverse correlation in the reversible prodromal stage of the disease. This study presents a novel and reusable electrochemical immunosensor chip for adiponectin detection to facilitate early warning and intervention of T2DM. Adiponectin antibodies are immobilized on the working electrode, where the surface is modified by gold nanoparticles (AuNPs). The measurements show a high sensitivity of 3.03 μA/decade over 14 regeneration cycles, along with a broad linear range of 0.5–25,000 ng/mL and a low limit of detection (LOD) of 0.0093 ng/mL. Integrating the sensing unit into a flow cell not only enables low reagent consumption and continuous-flow operation, but also allows the immunosensor to demonstrate excellent repeatability, reproducibility, and strong anti-interference capability. Finally, the proposed immunosensor delivers precise measurements of real blood samples, which provides a foundation for future studies and practical applications in T2DM clinical diagnosis.

Polyetheretherketone (PEEK)-based implants have become popular in hard tissue orthopedic and dental field. However, its inherent bio-inertness limited its applications for bone repair/substitution of osteoporosis patients, with poor osteogenesis capability. In order to ameliorate their bioactivity, the 3D porous PEEK substrate was created by sulfonate processing, and the substrate was subsequently incorporated with strontium (Sr) through a hydrothermal reaction in Sr(OH) 2 solutions. The adiponectin (APN) protein membrane was deposited on the substrate via polydopamine-assisted deposition. Surface characterization results disclosed that the nanostructures had been formed on sPEEK-Sr-APN surafces, and APN coatings on the substrates could adjust Sr release rate and further mediate cell-material interactions. in vitro experiments indicated that the cellular effects (proliferation and differentiation) of MC3T3-E1 were significantly increased with Sr/APN coordinated regulation. This study provides bioactive Sr and APN as promising active components for bio-functional bone regeneration/substitution, and optimizes the osteointegration of PEEK implants in clinic.

This study explored the possible connection between the insulin resistance-targeting protein adipokine lipocalin-2 (LCN-2) and NF-κB signaling pathway in the inflammatory microenvironment in PCOS-IR model rats to determine the pharmacological mechanism of modified Cangfu Daotan decoction (MCDD) intervention for PCOS-IR. We used a high-fat diet (42 days) combined with letrozole (1 mg/kg/day, 42 days) to establish a PCOS-IR rat model. From the third week after modeling, the rats were given continuous administration of MCDD (high dose with 31.68 g/kg, medium dose with 15.84 g/kg, and low dose with 7.92 g/kg) for 28 days. Serum, ovarian tissue, liver, and adipose tissue were collected after the last gavage. Enzyme-linked immunosorbent assay, hematoxylin-eosin (HE) staining, Masson staining, qRT-PCR, and Western blot experiments were performed to detect various indicators. Our results showed that MCDD could reduce body weight and abdominal fat weight; restore normal estrous cycle and ovarian function; alleviate fatty liver; regulate HOMA-IR and OGTT index; reduce serum inflammatory factor levels, LCN-2 level, and gene expression; and regulate the insulin signal transduction and NF-κB pathways in PCOS-IR rats. Thus, MCDD may play a role in improving ovarian function in PCOS-IR rats by downregulating NF-κB/LCN-2 proteins and upregulating the gene expression of Insr/Irs-1/Glut4 in the insulin signaling pathway in the inflammatory environment.

Both gut microbes and environmental contamination may cause metabolic disorders and obesity. However, the relationships among gut microbes, environmental contamination and obesity remain obscure. The drinking water on a national scale (31 cities in China) contained nanocolloid-pattern contamination at the mg/L level, a concentration that is 10- to 100-fold higher than commonly reported pollutants. Exposure to nanocolloids (environmentally related dose, 0.15 mg/kg) for three weeks increased the body weight and leptin levels of mice and decreased the expression of adiponectin. Nanocolloids increased the ratio of Firmicutes to Bacteroidetes, a typical obesity-related phenomenon, in the obese individuals. Oral administration of resveratrol verified the role of gut microbes in the tendency toward obesity induced by nanocolloids. The ratio of Firmicutes to Bacteroidetes is positively correlated with body weight and leptin levels. Compared to the control, the levels of triglycerides and high-density lipoprotein cholesterol were up- and downregulated by the tested nanocolloids at 0.15 mg/kg, respectively. Long-chain fatty acids, lipid metabolites and the expression of lipid synthesis-related genes (Fas, Srebp-1 and ACC-1) were also significantly increased by nanocolloids. The present study provides new insights that improve our understanding the risks of obesity associated with drinking water contamination that are mediated by gut microbes.

Purpose Myricetin, a dietary flavonoid, is effective in the treatment of obesity and insulin resistance by increasing glucose transport and lipogenesis in adipocyte and diminishing systemic inflammation in obesity. However, it has not been revealed yet whether myricetin is associated with brown adipose tissue (BAT) activation that tightly mediates systemic energy metabolism. Therefore, this study assessed whether myricetin activated brown adipose tissue in db/db mouse. Methods Myricetin (400 mg/kg) in distilled water was fed daily by oral gavage to leptin receptor-deficient db/db male mice at 4 weeks of age for 14 weeks. Body weight change, glucose intolerance test, blood lipid profile and BAT activation using PET-CT were assessed. Results After myricetin treatment for 14 weeks, systemic insulin resistance and hepatic steatosis were significantly improved in db/db mice with body weight reduction and myricetin led to decreased adipocity, improved plasma lipid profiles and increased energy expenditure. Myricetin activated BAT by upregulating thermogenic protein expression and activating mitochondrial biogenesis, eventually increasing heat dissipation in skin after cold exposure. In iWAT, myricetin induced beige formation, increased thermogenic protein expression and activated mitochondrial biogenesis. Consistently, thermogenic gene expression was upregulated when myricetin was introduced in C 3 H 10 T 1/2 cells during brown adipocytes differentiation. Moreover, the expression level of adiponectin was significantly increased in C 3 H 10 T 1/2 cells, adipose tissues and plasma after myricetin treatment. Conclusions These results highlight that myricetin prevents obesity and systemic insulin resistance by activating BAT and increasing adiponectin expression in BAT.

Camellia sinensis L. O. Kuntze has traditionally been used in Asian countries as a stimulant, a diuretic, and to prevent obesity. Studies in green tea are well-documented in literature, though the potential of fruit from the plant has never been studied in details. In the present study, the anti-adipogenic effect of aqueous extract of green tea seed cake extract (GTE) were analysed in-vitro and the anti-obesity effects were determined in-vivo in murine model fed high-fat and high-carbohydrate diets. We found that GTE inhibited the lipid accumulation in 3T3-L1 adipocyte and significantly lowered body weight, body fat-pad weights, blood lipid, glucose, insulin, and leptin levels in mice fed high-fat and high-carbohydrate diets. GTE suppressed the expression of important adipogenic genes (PPARγ, C/EBPα, SREBP, LPL, aP2 and leptin) and lipid metabolism genes (FAS). Furthermore, GTE induced the levels of adiponectin in serum and adipose tissue, as well as AMP-activated protein kinase (AMPK) in liver tissue. These results suggested that GTE ameliorates its anti-obesity effect through multiple cells signaling pathways in diets induced obesity in mice.

Bamboo shoot is a healthy food rich in dietary fiber (DF). However, its highly insoluble DF and fibrous texture limit its application in industrially processed foods. To achieve industrial processing of bamboo shoot, cellulase was used to improve the physical characteristics of bamboo shoot DF in this study. After enzymatic hydrolysis, the content of soluble DF (SDF) of bamboo shoot increased by 99.28% (from 5.53% to 11.02%) significantly ( p < 0.01). At the same time, the effect of enzymatic-modified bamboo SDF (EMBSDF) on streptozotocin-induced type 2 diabetes rats was explored. Results demonstrated that the high dose of EMBSDF (312.8 mg/kg) treated rats showed significant improvements in terms of glucose tolerance and insulin sensitivity ( p < 0.01) compared with the diabetes rats. Meantime, it was observed that the levels of glucagon-like peptide-1, adiponectin and interleukin-4 of high dose of EMBSDF compared with diabetes rats were increased ( p < 0.01) by 57.79%, 159.13%, and 6.17%, respectively. The tumor necrosis factor-α, C-reactive protein, and leptin levels were decreased ( p < 0.01) by 62.89%, 31.53%, and 7.84%, respectively. Furthermore, apparent kidney and pancreas histology improvements were found in high-dose and mid-dose EMBSDF-treated diabetes rats. These results indicated that the modified DF significantly improved diabetes.

Obesity has become a worldwide public health problem and continues to be one of the leading causes of chronic diseases. Obesity treatment is challenged by large drug doses, high administration frequencies and severe side effects. Herein, we propose an antiobesity strategy through the local administration of HaRChr fiber rods loaded with chrysin and grafted with hyaluronic acid and AtsFRk fiber fragments loaded with raspberry ketone and grafted with adipocyte target sequences (ATSs). The hyaluronic acid grafts double the uptake levels of HaRChr by M1 macrophages to promote phenotype transformation from M1 to M2 through upregulating CD206 and downregulating CD86 expressions. ATS-mediated targeting and sustained release of raspberry ketone from AtsFRk increase the secretion of glycerol and adiponectin, and Oil red O staining shows much fewer lipid droplets in adipocytes. The combination treatment with AtsFRk and the conditioned media from HaRChr-treated macrophages elevates adiponectin levels, suggesting that M2 macrophages may secrete anti-inflammatory factors to stimulate adipocytes to produce adiponectin. Diet-induced obese mice showed significant weight losses of inguinal (49.7%) and epididymal (32.5%) adipose tissues after HaRChr/AtsFRk treatment, but no effect was observed on food intake. HaRChr/AtsFRk treatment reduces adipocyte volumes, lowers serum levels of triglycerides and total cholesterol and restores adiponectin levels to those of normal mice. In the meantime, HaRChr/AtsFRk treatment significantly elevates the gene expression of adiponectin and interleukin-10 and downregulates tissue necrosis factor-α expression in the inguinal adipose tissues. Thus, local injection of cell-targeting fiber rods and fragments demonstrates a feasible and effective antiobesity strategy through improving lipid metabolism and normalizing the inflammatory microenvironment.

It is clinical reported that YangXue QingNao Wan (YXQNW) combined with donepezil can significantly improve the cognitive function of AD patients. However, the mechanism is not clear. A network pharmacology approach was employed to predict the protein targets and affected pathways of YXQNW in the treatment of AD. Based on random walk evaluation, the correlation between YXQNW and AD was calculated; while a variety of AD clinical approved Western drugs were compared. The targets of YXQNW were enriched and analyzed by using the TSEA platform and MetaCore. We proved that the overall correlation between YXQNW and AD is equivalent to clinical Western drugs, but the mechanism of action is very different. Firstly, YXQNW may promote cerebral blood flow velocity by regulating platelet aggregation and the vasoconstriction/relaxation signal pathway, which has been verified by clinical meta-analysis. Secondly, YXQNW may promote Aβ degradation in the liver by modulating the abnormal glucose and lipid metabolisms via the adiponectin-dependent pathway, RXR/PPAR-dependent lipid metabolism signal pathway, and fatty acid synthase activity signal pathway. We also verified whether YXQNW indeed promoted Aβ degradation in hepatic stellate cells. This work provides a novel scientific basis for the mechanism of YXQNW in the treatment of AD.
