Kawasaki disease (KD) is an autoimmune disorder that can induce coronary artery
aneurysms, particularly in the case of delayed diagnosis and/or treatment. Early
diagnosis is important for treatment and reduces the risk of heart injury. The
aim of the present study was to identify differentially expressed genes by
comparing the levels of gene expression in human umbilical vein endothelial cells
following treatment with plasma from healthy individuals and patients with acute
or convalescent KD. Following comparison of the control and acute KD groups, 385
up-regulated and 537 down-regulated genes were identified in the acute KD group.
In the convalescent group, 505 and 879 genes were up-regulated and
down-regulated, respectively, relative to the control group. Genes involved in
the immune system and cell growth factors were up-regulated, while genes
functioning in methylation were down-regulated, following treatment with KD
plasma. In addition, five potential candidate molecular markers of KD, C-X-C
motif chemokine ligand 2 (CXCL2), interleukin (IL) 8, tripartite motif containing
58 (TRIM58), immunoglobulin superfamily member 3 (IGSF3) and runt related
transcription factor 1 (RUNX1) were identified by microarray analysis and
verified using quantitative polymerase chain reaction. A significant positive
correlation was identified between the neutrophil polys and expression levels of
four of these candidate genes, including CXCL2, IL8, TRIM58, and IGSF3 (all
P<0.01; R(2)?0.64). However, only CXCL2 expression was significantly positively
correlated with neutrophil polys (P=0.01; R(2)=0.64) and neutrophil bands
(P<0.001; R(2)=0.73). These results indicate that CXCL2 serves a crucial role in
the injury of endothelial cells by KD plasma.
