The host factor LSF represses the human immunodeficiency virus type 1 long terminal repeat (LTR) by mediating recruitment of histone deacetylase. We show that pyrrole-imidazole polyamides targeted to the LTR can specifically block LSF binding both in vitro and within cells via direct access to chromatin, resulting in increased LTR expression.
宿主因子LSF通过介导组蛋白去乙酰化酶的募集来抑制1型人类免疫缺陷病毒(HIV-1)的长末端重复序列(LTR)。我们发现,靶向LTR的吡咯-咪唑聚酰胺能够通过直接作用于染色质,在体外和细胞内特异性地阻断LSF的结合,从而导致LTR表达增加。
