ABSTRACT
Objective To explore the functional activity of rs6858698 and its effect on susceptibility to chronic lymphocytic leukemia.Methods Luciferase reporter assay was used to detect the regulatory activity of rs6858698-Containing fragment.CRISPR/Cas9 system was employed to construct stable cell line with point mutation at rs6858698 locus.RNA-seq was used to identify differentially expressed genes between wildtype cells and mutant cells.Real-time quantitative PCR(RT-qPCR)and CRISPR interference(CRISPRi)assays were used to validate the results of RNA-seq.Results The rs6858698 -Containing region with allele C showed significantly higher enhancer activity than the region containing allele G.A total of 140 differentially expressed genes were identified in HEK293T cells after changing the allele from G to C,These genes are mainly enriched in nine bio-logical processes, including epigenetic modification.Conclusions rs6858698 has regulatory activity, which can affect the individual susceptibility to chronic lymphocytic leukemia by influencing the expression of genes related to the epigenetic modification.
