Abstract

Background: Rheumatoid arthritis (RA) is one complex chronic autoimmune disease, resulting body pain and badly affect the health of RA patients. Zinc finger and BTB domain containing 16 (ZBTB16) has been reported to participate into many diseases including osteoarthritis and osteoporosis.

Objective: To verify the regulatory functions of ZBTB16 in RA progression keep dimness.

Methods: The mRNA expressions were tested through RT-qPCR. The protein expressions were evaluated through western blot. The pathological changes of synovial tissues were determined through HE staining. The erosion and destruction of bone tissues were examined through safranin-O/fast green staining. The levels of TNF-α, IL-1β, IL-6 and MMP-3 were testified through ELISA. The fluorescence intensity of proteins was assessed through IF assay.

Results: Firstly, it was uncovered that ZBTB16 expression was markedly reduced in the synovium tissues of RA patients through analyzing GSE55235 expression profile by GEO2R online tool. Next, ZBTB16 expression was down-regulated in synovial tissues of RA patients. Moreover, ZBTB16 can alleviate the degree of paw swelling in CIA mice. ZBTB16 improved the pathological changes of synovial tissues in CIA mice. The levels of inflammatory factors and matrix metalloproteinase were increased in CIA mice, but these impacts were reversed after ZBTB16 amplification. ZBTB16 can relieve pannus in CIA mice. Besides, the triggered GRK2/HIF-1α pathway in CIA mice can be retarded after ZBTB16 overexpression.

Conclusion: ZBTB16 exerted anti-angiogenic effects in RA by blocking GRK2/HIF-1α pathway. This work hinted that ZBTB16 may be one useful target for RA treatment.

ZBTB16通过调节HIF-1α途径在类风湿关节炎中发挥抗血管生成作用。
背景:类风湿关节炎(Rheumatoid arthritis, RA)是一种复杂的慢性自身免疫性疾病,可引起全身疼痛,严重影响RA患者的健康。锌指和BTB结构域16 (ZBTB16)参与骨关节炎、骨质疏松等多种疾病的发生。目的:验证ZBTB16在类风湿关节炎进展中的调控作用。方法:采用RT-qPCR检测mRNA表达。western blot检测蛋白表达。HE染色观察滑膜组织的病理变化。通过红花素- o /快绿染色检测骨组织的侵蚀和破坏情况。ELISA法检测TNF-α、IL-1β、IL-6、MMP-3水平。IF法测定蛋白的荧光强度。结果:首先,通过GEO2R在线工具分析GSE55235表达谱,发现ZBTB16在RA患者滑膜组织中的表达明显降低。接下来,ZBTB16在RA患者滑膜组织中的表达下调。此外,ZBTB16还能减轻CIA小鼠足部肿胀程度。ZBTB16改善了CIA小鼠滑膜组织的病理改变。炎症因子和基质金属蛋白酶水平在CIA小鼠中升高,但这些影响在ZBTB16扩增后被逆转。ZBTB16对CIA小鼠有明显的镇痛作用。此外,ZBTB16过表达可延缓CIA小鼠GRK2/HIF-1α通路的激活。结论:ZBTB16通过阻断GRK2/HIF-1α通路发挥抗RA血管生成作用。这项工作提示ZBTB16可能是治疗类风湿性关节炎的一个有用的靶点。

期刊介绍: Founded in 1972 by Professor A. Oehling, Allergologia et Immunopathologia is a forum for those working in the field of pediatric asthma, allergy and immunology. Manuscripts related to clinical, epidemiological and experimental allergy and immunopathology related to childhood will be considered for publication. Allergologia et Immunopathologia is the official journal of the Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) and also of the Latin American Society of Immunodeficiencies (LASID). It has and independent international Editorial Committee which submits received papers for peer-reviewing by international experts. The journal accepts original and review articles from all over the world, together with consensus statements from the aforementioned societies. Occasionally, the opinion of an expert on a burning topic is published in the "Point of View" section. Letters to the Editor on previously published papers are welcomed. Allergologia et Immunopathologia publishes 6 issues per year and is included in the major databases such as Pubmed, Scopus, Web of Knowledge, etc.
