Iron is indispensable for the viablility of nearly all living organisms, and it is imperative for cells, tissues, and organisms to acquire this essential metal sufficiently and maintain its metabolic stability for survival. Disruption of iron homeostasis can lead to the development of various diseases. There is a robust connection between iron metabolism and infection, immunity, inflammation, and aging, suggesting that disorders in iron metabolism may contribute to the pathogenesis of arthritis. Numerous studies have focused on the significant role of iron metabolism in the development of arthritis and its potential for targeted drug therapy. Targeting iron metabolism offers a promising approach for individualized treatment of arthritis. Therefore, this review aimed to investigate the mechanisms by which the body maintains iron metabolism and the impacts of iron and iron metabolism disorders on arthritis. Furthermore, this review aimed to identify potential therapeutic targets and active substances related to iron metabolism, which could provide promising research directions in this field.

目的:利用无创测量技术提取的中国人群面部皮肤理化参数建立表征皮肤老化表型的新指标。方法:招募100例不同年龄段的健康受试者,通过皮肤无创测试仪器检测皮肤含水量等皮肤参数,进行主成分分析(PCA)和广义线性模型分析(GLM)。结果:相关性分析发现胶原蛋白密度与年龄呈显著负相关(r=-0.31,P<0.01),眼角弹性指标R5(r=-0.612,P<0.0001)等参数明显随年龄增加而降低。广义线性模型建立的SAI与年龄关系更为显著(r=0.699,P<0.0001)。结论:面部皮肤老化主要表现为胶原蛋白流失,弹性降低,皮肤变黑变红,利用无创测量参数和广义线性模型建立的皮肤老化指数可以用来表征面部皮肤复杂的老化特征。

为了寻找特发性肺纤维化(IPF)的潜在治疗靶点,从GEO获取IPF基因芯片数据,用R分析差异表达基因和通路;用STRING和Cytoscape筛选枢纽(HUB)基因;RNA-Seq和单细胞数据验证,肺纤维化小鼠实验验证,筛选具有相关性的基因,分析潜在通路。结果显示:基因芯片数据集GSE10667、GSE53845、GSE48149共116例样本,差异基因132个,主要富集在细胞外基质、胶原等通路。STRING和Cytoscape筛选HUB基因,主要为COL1A1、CXCL12、LEPREL1等基因,其中LEPREL1表达显著下调(GSE10667,P_(adj)=0.00096;GSE53845,P_(adj)=0.0001048;GSE48149,P_(adj)=0.01517)。LEPREL1在RNA-Seq数据集GSE92592(P_(adj)=0.0288)、GSE83717(P_(adj)=0.006268)、GSE150910(P_(adj)=1.9528e-30)中均显著下调;在单细胞数据(GSE135893)中主要在AT2细胞中表达并有下调趋势;在肺纤维化小鼠的RT-qPCR和IHC中也表达显著下调。差异表达基因中有81个与LEPREL1具相关性的基因,主要与细胞黏附、钙离子、胶原形成、Wnt等通路相关。IPF的差异基因主要富集在胶原和细胞外基质通路,且AT2细胞中下调的LEPREL1可能是其潜在治疗靶点。

目的:观察UVB照射引起的基底膜屏障损伤的特征。方法:使用40 mJ/cm^(2)UVB照射HaCaT细胞,通过RNA-seq数据分析研究基底膜屏障相关基因的表达特征。通过透射电镜和免疫荧光染色,在3组离体皮肤组织中观察50 mJ/cm^(2)UVB连续照射3 d后基底膜结构及关键屏障蛋白含量的变化。结果:发现了18个与基底膜相关的基因,其中17个基因表达下调,COL4A4、COL4A5、COL4A6、ITGB1、ITGA3、ITGA4、ITGA6、LAMA5的表达水平下调倍数超过1.5倍(P<0.05),而HPSE的表达上调了2.4倍(P<0.0001)。在离体皮肤组织实验中,UVB照射后观察到基底膜透明层和致密层断裂,半桥粒破坏,完整性和连续性受损,并且整合素蛋白含量下降(P<0.05)。结论:UVB照射会下调基底膜屏障结构相关基因的表达,上调乙酰肝素酶基因表达,造成基底膜结构紊乱以及基底膜关键屏障蛋白降解,使基底膜屏障受损。
