We found that rs1015164 marks variation in an activating transcriptionfactor 1 binding site that controls expression of the antisense long noncodingRNA (lncRNA) CCR5AS. Knockdown or enhancement of CCR5AS expression resulted ina corresponding change in CCR5 expression on CD4+ T cells. CCR5AS interferedwith interactions between the RNA-binding protein Raly and the CCR5 3' untranslatedregion, protecting CCR5 messenger RNA from Raly-mediated degradation. Reductionin CCR5 expression through inhibition of CCR5AS diminished infection of CD4+ Tcells with CCR5-tropic HIV in vitro. These data represent a rare determinationof the functional importance of a genome-wide disease association whereexpression of a lncRNA affects HIV infection and disease progression. 推荐理由: 这篇文章代表了全基因组疾病关联的功能重要性的罕见确定,其中lncRNA的表达影响HIV感染和疾病进展。 end |
