We aim to explore the effects of peroxisome proliferator-activated receptor δ (PPARδ) subtypes on serum lipid profiles in obese rhesus monkey, especially evaluate the efficacy of investigational new drug (HS00098). Methods: First, a prototype of obese rhesus monkey was established by continuously feeding test animals a high fat diet for 2 months. Fifteen obese rhesus monkeys were randomly divided into 3 groups, and the 2 test groups were treated with GW 501516 and HS00098. The test groups were administered doses of 0.3 mg/kg for 1 month, then with 1 mg/kg for 1 month, and finally with 3 mg/kg for 1 month. The control group received placebo treatment. In each experiment, the body weight of each animal was measured and recorded initially and prior to changing the dose of the drug each month. The total cholesterol, blood glucose, triglyceride, high density lipoprotein cholesterol, low-density lipoprotein cholesterol, serum Apo-A1, Apo-B100 and insulin were tested. Results: The average body weight gain of the GW501516 and HS00098 groups was significantly lower than that of the control group. The group receiving the HS00098 treatment had a higher signifycant increase in high density lipoprotein and apo-A1 (P < 0.05) than the control monkeys, while the total cholesterol, triglycerides, low density lipoproteins, apo-B100, and insulin (P < 0.05 or P < 0.01) were significantly decreased. Compared with GW50-1516, the effects of HS00098 on serum lipid profiles in diet-induced obese rhesus monkeys are more obvious. Conclusion: These results suggested that the investigational drug (HS00098) can effectively reduce body weight, blood lipid and blood sugar levels of diet-induced obese rhesus monkeys.展开更多

Emerging evidence, however, indicates that GLP-1RAs mayalso have therapeutic potential in inflammatory and autoimmune conditions. Thisreview explores the evolving role of GLP-1RAs in managing rheumatic diseases,including osteoarthritis, rheumatoid arthritis, psoriatic arthritis, and systemiclupus erythematosus. Studies suggest that GLP-1RAs reduce inflammation bymodulating immune cell activity, increasing anti-inflammatory cytokine production,shifting macrophage polarization toward an anti-inflammatory phenotype,and enhancing regulatory T-cell function to maintain immune homeostasis. Theseimmunomodulatory effects point toward a promising adjunctive strategy incurrent clinical practice for patients with rheumatic diseases, particularly thosewith metabolic comorbidities. Further clinical trials are warranted to validatethese findings, clarify underlying mechanisms, and assess long-term safety,ultimately paving the way for novel treatment approaches in rheumatology.展开更多

文摘Type 2 diabetes mellitus(T2DM)is one of the most prevalent chronic metabolic disorder characterized by insulin resistance and relative insulin deficiency.PPARδactivation has been reported to have several beneficial effects in alleviating dyslipidemia and insulin resistance.GW501516,a synthetic PPARδagonist,was developed to target hyperlipidemia and reported to alleviating insulin resistance in T2DM.Studies indicate that PPARδactivation by GW501516 can reduce adiposity,enhanceβ-oxidation of fatty acids,and improve insulin sensitivity in T2DM animal models.Despite its therapeutic promise,potential carcinogenic effects also have been reported.Therefore,a comprehensive non-targeted and targeted lipidomics study was carried out to evaluate the regulatory effect of GW501516 in the plasma of db/db mice.The results revealed that GW501516 is effective in reducing the accumulation of lipids in the fatty acid metabolism pathway and lipid classes including triglycerides and phosphatidylglycerols.Furthermore,activation of PPARδby GW501516 demonstrated a beneficial effect on improving circulating cholesterol homeostasis.However,while the levels of hexosylceramides and sphingomyelin were partially reversed,ceramide levels,which are negatively associated with insulin sensitivity,were significantly elevated by GW501516.Despite these mixed outcomes,the study highlights both the promising therapeutic potential of PPARδactivation in metabolic disorders and the safety concerns regarding long-term clinical use.The findings provide valuable insights into the impact of GW501516-induced PPARδactivation on lipid metabolism in T2DM,contributing to a better understanding of its therapeutic potential and risks.
文摘Metabolic dysfunction-associated steatotic liver disease(MASLD)is a highly prevalent liver pathology in need of novel pharmacological treatments to complement lifestyle-based interventions.Nuclear receptor agonists have been under scrutiny as potential pharmacological targets and as of today,resmetirom,a thyroid hormone receptor b agonist,is the only approved agent.The dual PPARαandδagonist elafibranor has also undergone extensive clinical testing,which reached the phase III clinical trial but failed to demonstrate a beneficial effect on MASLD.As alcohol-associated liver disease and MASLD can be interconnected,whether elafibranor might be affective against liver disease caused by alcohol consumption is worth investigating.Writing recently in the World Journal of Gastroenterology,Koizumi et al reported using a mouse model of alcoholassociated liver disease and found that hepatic steatosis,liver fibrosis,and hepatocyte apoptosis were alleviated by administration of elafibranor.Although preclinical in nature,these data support the potential beneficial action of elafibranor in alcohol-induced MASLD,warranting the testing of this molecule in patients with steatotic liver disease caused by alcohol consumption.

文摘BACKGROUND With accumulating evidence showing a benefit in the renal and cardiovascular systems,diabetes guidelines recommend that patients with diabetes and chronic kidney disease(CKD)be treated with sodium-glucose cotransporter-2 inhibitor(SGLT2i)and/or glucagon like peptide-1 receptor agonists(GLP-1RAs)for renal protection.The real-world efficacy of the two medications on the urinary albumin-creatinine ratio(UACR)and estimated glomerular filtration rate(eGFR)remains to be explored.AIM To evaluate the SGLT2i and GLP-1RA application rates and UACR alterations after intervention in a real-world cohort of patients with diabetes.METHODS A cohort of 5482 patients with type 2 diabetes were enrolled and followed up at the Integrated Care Clinic for Diabetes of Peking University First Hospital for at least 6 months.Propensity score matching was performed,and patients who were not recommended for GLP-1RA or SGLT2i with comparable sex categories and ages were assigned to the control group at a 1:2 ratio.Blood glucose,body weight,UACR and eGFR were evaluated after 6 months of treatment in real-world clinical practice.RESULTS A total of 139(2.54%)patients started GLP-1RA,and 387(7.06%)received SGLT2i.After 6 months,the variations in fasting blood glucose,prandial blood glucose,and glycosylated hemoglobin between the GLP-1RA group and the SGLT2i and control groups were not significantly different.UACR showed a tendency toward a greater reduction compared with the control group,although this difference was not statistically significant(GLP-1RA vs control,-2.20 vs 30.16 mg/g,P=0.812;SGLT2i vs control,-20.61 vs 12.01 mg/g,P=0.327);eGFR alteration also showed no significant differences.Significant weight loss was observed in the GLP-1RA group compared with the control group(GLP-1RA vs control,-0.90 vs 0.27 kg,P<0.001),as well as in the SGLT2i group(SGLT2i vs control,-0.59 vs-0.03 kg,P=0.010).CONCLUSION Compared with patients who received other glucose-lowering drugs,patients receiving SGLT2i or GLP-1RAs presented significant weight loss,a decreasing trend in UACR and comparable glucose-lowering effects in realworld settings.
