Use of cbx4 as target for activation of hiv-1 latent infection

Abstract

The present invention relates to a use of CBX4 as a target for activation of HIV-1 latent infection. The present invention found by research that, inhibiting CBX4 causes a good ability for activation of HIV-1 latent, a knockdown of CBX4 can effectively promote a transcription of LTR of HIV-1; and afterwards the present invention has found that, by the knockdown of CBX4 in a J-lat 10.6 cell model of HIV-1 latent infection, GFP gene expression is up-regulated, and HIV-1 can be effectively activated. An overexpression of the CBX4 protein in TZM-bl cells can effectively decrease a transcriptional activity of LTR of HIV-1. It is found by further detection that, decreased expression of CBX4 protein will reduce a degree of enrichment of H3K9 trimethylation and H3K27 trimethylation of LTR of HIV-1, thereby activating HIV-1 latent infection.
