Introduction: The rising prevalence of musculoskeletal pathologies in developed countries has caused a dramatic impact on social welfare. Amidst these musculoskeletal pathologies is Rheumatoid arthritis (RA), a chronic systemic autoimmune disease that mostly affects the synovium. RA metabolic-associated alterations, including distorted adipokine production, enhance RA inflammatory environment. Among the altered adipokines, visfatin is particularly involved in RA inflammation and catabolism and stands out as an essential enzyme linked to critical cell features.
Areas covered: We discuss the potential mechanism supporting the contribution of visfatin to RA and the association between RA and obesity. We discuss the repurposing of cancer-tested drugs to inhibit visfatin in the context of RA. Additionally, we address the possibility of combining these drugs with current RA therapy. Finally, we explore the future of visfatin as an RA biomarker or therapeutic target.
Expert opinion: Inhibition of visfatin has become an interesting therapeutic approach for RA pathology. Such a feat has already been attained in oncology using small molecule inhibitors, which suggest that a similar course of action would be worth pursuing in the RA context. Visfatin will become an important biomarker and therapeutic target for RA. 相似文献
目的:探讨慢性左心衰竭患者血浆内脏脂肪素与高敏 C 反应蛋白(hs-CRP)的水平变化。方法选取慢性左心衰竭患者(心力衰竭组)及同期健康体检者(对照组)各60例,分别检测血浆内脏脂肪素、hs-CRP 水平。结果心力衰竭组患者血浆内脏脂肪素低于对照组( P <0.01),hs-CRP 高于对照组( P <0.01);Ⅲ~Ⅳ级心力衰竭患者血浆内脏脂肪素低于Ⅰ~Ⅱ级患者( P <0.01),hs-CRP 高于Ⅰ~Ⅱ级患者( P <0.01)。结论慢性左心衰竭患者存在血浆内脏脂肪素降低及 hs-CRP 升高,随着病情加重变化更为明显,检测血浆内脏脂肪素与 hs-CRP 可作为评估慢性左心衰竭病情严重程度的辅助指标。 相似文献
ObjectiveInterferon-γ (IFN-γ) plays an important role in apoptosis and was shown to increase the risk of diabetes.Visfatin, an adipokine, has anti-diabetic, anti-tumor, and regulating inflammatory properties. In this study we investigated the effect of visfatin on IFN-γ-induced apoptosis in rat pancreatic β-cells. MethodsThe RINm5F (rat insulinoma cell line) cells exposed to IFN-γ were treated with or without visfatin. The viability and apoptosis of the cells were assessed by using MTT and flow cytometry. The expressionsof mRNA and protein were detected by using real-time PCR and western blot analysis. ResultsThe exposure of RINm5F cells to IFN-γ for 48 h led to increased apoptosis percentage of the cells. Visfatin pretreatment significantly increased the cellviability and reduced the cell apoptosis induced by IFN-γ. IFN-γ-induced increase in expression of p53 mRNA and cytochrome c protein, decrease in mRNA and protein levels of anti-apoptotic protein Bcl-2 were attenuated by visfatin pretreatment. Visfatin alsoincreasedAMPK and ERK1/2phosphorylation and the anti-apoptotic action of visfatin was attenuated by the AMPK and ERK1/2 inhibitor. ConclusionThese results suggested that visfatin protected pancreatic islet cells against IFN-γ-induced apoptosis via mitochondria-dependent apoptotic pathway. The anti-apoptotic action of visfatin is mediated by activation of AMPK and ERK1/2 signaling molecules. 相似文献
