Abstract:

Objective To analyze the differentially expressed genes and key proteins in T cells between acute and chronic idiopathic thrombocytopenic purpura (ITP) in children and provide the basis for the prevention and therapies of this disease. Methods Microarray gene chip data from T cells of children with acute or chronic ITP were downloaded from the GEO Database. The gene expression profiles,gene function,and protein interaction network were analyzed by R,QOE,Networkanalyst,GCBI,and GenClip. Results The gene expression profiles between these two groups were significantly different. Among the 54 675 genes analyzed,there were 457 (0.84%) differentially expressed genes between these two groups. In the protein interaction networks among top 20 differentially expressed genes,the core was JUN(down-regulated) and ITCH(up-regulated),which were both related to the tumor necrosis factor signaling pathway;differentially expressed genes were mainly related to the activation and tolerance of T cell. Conclusions The gene expression profiles differ between acute and chronic ITP patients,suggesting that the gene transcription profile plays a regulatory role in the different stages of ITP. JUN and ITCH may play a role in predict the progression of ITP and may exert their biological functions by regulating the tumor necrosis factor signaling pathway.
