The Rs12569232 SNP Association with Vogt-Koyanagi-Harada Disease and Behcet's Disease is Probably Mediated by Regulation of Linc00467 Expression

Purpose: To investigate whether the rs12569232 SNP association with Vogt-Koyanagi-Harada disease and Behcet's disease is mediated by regulation of Linc00467 expression. Methods: The expression of linc00467 was detected by real-time PCR. Adenovirus carrying the linc00467 was transduced into CD4(+)T cells and the effect on cell viability was measured by the CCK-8 test. Human proteome microarray and starBase 2.0 were used to identify the binding proteins of linc00467 and RNA Immunoprecipitation (RIP) was used to confirm the identity of bound proteins. Results: The rs12569232 was associated with the expression of linc00467. The expression of linc00467 was up-regulated in PBMCs and CD4(+)T cells from VKH disease and BD patients. Over-expression of linc00467 increased cell viability of CD4(+)T cells. HUR was the common binding protein identified by the two methods and confirmed by RIP. Conclusions: The rs12569232 association with VKH disease and BD may be mediated via regulating the expression of linc00467.
