New advances of adiponectin in regulating obesity and related metabolic syndromes

Obesity and related metabolic syndromes have been recognized as important disease risks,in which the role of adipokines cannot be ignored.Adiponectin(ADP)is one of the key adipokines with various beneficial effects,including improving glucose and lipid metabolism,enhancing insulin sensitivity,reducing oxidative stress and inflammation,promoting ceramides degradation,and stimulating adipose tissue vascularity.Based on those,it can serve as a positive regulator in many metabolic syndromes,such as type 2 diabetes(T2D),cardiovascular diseases,non-alcoholic fatty liver disease(NAFLD),sarcopenia,neurodegenerative diseases,and certain cancers.Therefore,a promising therapeutic approach for treating various metabolic diseases may involve elevating ADP levels or activating ADP receptors.The modulation of ADP genes,multimerization,and secretion covers the main processes of ADP generation,providing a comprehensive orientation for the development of more appropriate therapeutic strategies.In order to have a deeper understanding of ADP,this paper will provide an all-encompassing review of ADP.

Study on the Correlation between Adiponectin and Bone Mineral Density in Postmenopausal Women from Guangxi Zhuang Autonomous Region

Objectives: To explore the relationship between adiponectin (APN) and bone mineral density in this Zhuang ethnic group, thus providing a basis underpinning the prevention and treatment of osteoporosis (OP). Methods: Zhuang women over 50 years old in Guangxi Zhuang Autonomous Region were included in the study. The broadband ultrasound attenuation (BUA) was adopted as the reference to calculate the T value. Quantitative ultrasonic bone density was measured on the right. Body composition measuring instrument was used to measure weight, fat, and muscle mass. Plasma APN level was detected by ELISA and blood lipids were detected by enzymatic method. Results: Plasma APN level was found with significant differences in the normal bone mineral density group, bone mineral density reduction group, and osteoporosis group (P β = −0.176, P = 0.001) when the partial correlation coefficient of APN is −0.210. Elevated APN was an independent risk factor for bone mineral density reduction (OR = 1.191, 95%CI: 1.004 - 1.407, P = 0.04) and OP (OR = 1.1337, 95%CI: 1.137 - 1.572, P Conclusion: Increased APN in postmenopausal women of Zhuang is an independent risk factor for OP. The application of APN in the OP screening and prevention of middle-aged and ageing Zhuang women still needs further research.

Growth hormone improves insulin resistance in visceral adipose tissue after duodenal-jejunal bypass by regulating adiponectin secretion

BACKGROUND The mechanism of improvement of type 2 diabetes after duodenal-jejunal bypass(DJB)surgery is not clear.AIM To study the morphological and functional changes in adipose tissue after DJB and explore the potential mechanisms contributing to postoperative insulin sensitivity improvement of adipose tissue in a diabetic male rat model.METHODS DJB and sham surgery was performed in a-high-fat-diet/streptozotocin-induced diabetic rat model.All adipose tissue was weighed and observed under microscope.Use inguinal fat to represent subcutaneous adipose tissue(SAT)and mesangial fat to represent visceral adipose tissue.RNA-sequencing was utilized to evaluate gene expression alterations adipocytes.The hematoxylin and eosin staining,reverse transcription-quantitative polymerase chain reaction,western blot,and enzyme-linked immunosorbent assay were used to study the changes.Insulin resistance was evaluated by immunofluorescence.RESULTS After DJB,whole body blood glucose metabolism and insulin sensitivity in adipose tissue improved.Fat cell volume in both visceral adipose tissue(VAT)and SAT increased.Compared to SAT,VAT showed more significantly functional alterations after DJB and KEGG analysis indicated growth hormone(GH)pathway and downstream adiponectin secretion were involved in metabolic regulation.The circulating GH and adiponectin levels and GH receptor and adiponectin levels in VAT increased.Cytological experiment showed that GH stimulated adiponectin secretion and improve insulin sensitivity.CONCLUSION GH improves insulin resistance in VAT in male diabetic rats after receiving DJB,possibly by increasing adiponectin secretion.

Adiponectin orchestrates testosterone suppression in biological pathways

This current review highlights adiponectin engagement with AdipoR1 and AdipoR2 which subsequently triggers pathways such as AMPK,PPARα,and MAPK,thereby modulating testicular steroidogenesis.Adiponectin's actions on Leydig and adrenal cells inhibit androgen secretion by suppressing the steroidogenic acute regulatory protein(StAR).Given that StAR facilitates cholesterol to testosterone conversion,AMPK inhibits this process by modulating cholesterol transport and suppressing StAR expression through multiple avenues.Furthermore,adiponectin-induced PPARαactivation impedes mitochondrial cholesterol influx,further modulating androgen biosynthesis.The suppressive influence of PPARαon steroidogenic genes,notably StAR,is evident.Collectively,adiponectin signalling predominantly attenuates androgen production,ensuring metabolic and reproductive equilibrium.Imbalances,as seen in conditions like hypogonadism and obesity-related infertility,highlight their crucial roles and potential clinical interventions for reproductive disorders.

Exercise preconditioning alleviates ischemia-induced memory deficits by increasing circulating adiponectin

Cerebral ischemia is a major health risk that requires preventive approaches in addition to drug therapy.Physical exercise enhances neurogenesis and synaptogenesis,and has been widely used for functional rehabilitation after stroke.In this study,we determined whether exercise training before disease onset can alleviate the severity of cerebral ischemia.We also examined the role of exercise-induced circulating factors in these effects.Adult mice were subjected to 14 days of treadmill exercise training before surgery for middle cerebral artery occlusion.We found that this exercise pre-conditioning strategy effectively attenuated brain infarct area,inhibited gliogenesis,protected synaptic proteins,and improved novel object and spatial memory function.Further analysis showed that circulating adiponectin plays a critical role in these preventive effects of exercise.Agonist activation of adiponectin receptors by Adipo Ron mimicked the effects of exercise,while inhibiting receptor activation abolished the exercise effects.In summary,our results suggest a crucial role of circulating adiponectin in the effects of exercise pre-conditioning in protecting against cerebral ischemia and supporting the health benefits of exercise.

Boiogito Increases the Synthesis and Secretion of Adiponectin by Promoting Differentiation in Cultured Human Adipocytes

Boiogito (BOT) ameliorates insulin resistance and diabetes in several animal models;however, the underlying mechanisms for these in vivo effects remain unclear. Thiazolidine derivatives, which are peroxisome proliferator-activated receptor γ (PPARγ) agonists for the treatment of type II diabetes, promote adiponectin production by inducing adipocyte differentiation, thereby reducing insulin resistance. This study aimed to evaluate the effect of BOT on adipocyte differentiation using cultured human visceral preadipocytes (HVPAds) compared with the thiazolidine derivative troglitazone (TRG). We investigated the effects of BOT (0.125 - 1 mg/mL) and TRG (10 μM) on the differentiation of adipocytes treated with or without tumor necrosis factor-α (TNF-α: 5 ng/mL). On day 14 of culture, the following adipocyte differentiation marker levels were measured: intracellular lipids, extracellular (i.e., medium) adiponectin, and intracellular differentiation-related genes (PPARγ, CCAAT/enhancer binding protein, adiponectin, differentiation cluster 36, glucose transporter type 4). BOT and TRG increased factors associated with differentiation including lipid, adiponectin, and differentiation-related gene expression levels compared with the controls. The increases in these differentiation markers were inhibited by the PPARγ antagonist GW9662 (20 μM). Furthermore, TNF-α decreased all differentiation marker levels. The decreases in differentiation markers were inhibited by BOT and TRG;however, these inhibitory effects were blocked by GW9662. The results suggest that BOT increases the synthesis and secretion of adiponectin by promoting differentiation similar to TRG. This study is the first to demonstrate that adipocyte differentiation-promoting activity is a mechanism for the beneficial effects of BOT on diabetes and insulin resistance.

Adiponectin as a therapeutic target for diabetic foot ulcer

The global burden of diabetic foot ulcers(DFUs)is a significant public health concern,affecting millions of people worldwide.These wounds cause considerable suffering and have a high economic cost.Therefore,there is a need for effective strategies to prevent and treat DFUs.One promising therapeutic approach is the use of adiponectin,a hormone primarily produced and secreted by adipose tissue.Adiponectin has demonstrated anti-inflammatory and antiatherogenic properties,and researchers have suggested its potential therapeutic applications in the treatment of DFUs.Studies have indicated that adiponectin can inhibit the production of pro-inflammatory cytokines,increase the production of vascular endothelial growth factor,a key mediator of angiogenesis,and inhibit the activation of the intrinsic apoptotic pathway.Additionally,adiponectin has been found to possess antioxidant properties and impact glucose metabolism,the immune system,extracellular matrix remodeling,and nerve function.The objective of this review is to summarize the current state of research on the potential role of adiponectin in the treatment of DFUs and to identify areas where further research is needed in order to fully understand the effects of adiponectin on DFUs and to establish its safety and efficacy as a treatment for DFUs in the clinical setting.This will provide a deeper understanding of the underlying mechanisms of DFUs that can aid in the development of new and more effective treatment strategies.
