WebJun 1, 1998 · However, the use of HIV-1 vectors raises concerns about their safety. Here we describe a self-inactivating HIV-1 vector with a 400-nucleotide deletion in the 3′ long terminal repeat (LTR). The deletion, which includes the TATA box, abolished the LTR promoter activity but did not affect vector titers or transgene expression in vitro. WebDNA methylation of retroviral promoters and enhancers localized in the provirus 5' long terminal repeat (LTR) is considered to be a mechanism of transcriptional suppression …

Webretroviral long terminal repeats (LTRs) determine mainly the transcriptional level of newly introduced genes in target cells. Most of the cis-acting elements are found within the direct repeat (DR) [5–10]. In addition to in the DR, the elements were also identified in the upstream control region (UCR; the upstream region of the DR) [11–14].
