Cis–Acting RNA Elements of Human Immunodeficiency Virus
The World Health Organization has indicated that effective control of the HIV/AIDS pandemic is the world’s most urgent public health challenge. The 2009 UNAIDS Global Facts and Figures report estimated that almost 60 million people have been infected with the virus and that 25 million AIDS-related deaths have occurred since the pandemic began in the early 1980s. In 2008, there were approximatel...
متن کاملCis-acting elements in the antigenomic promoter of Nipah virus.
Genome synthesis in paramyxoviruses, including Nipah virus (NiV), is controlled by sequence elements that reside in the non-coding nucleotides at the 5'-trailer (3'-antigenomic) end that make up the antigenomic promoter (AGP). Using a chloramphenicol acetyl transferase-based plasmid-driven minigenome system, the terminal 96 nt of NiV AGP were first mutagenized in blocks of three hexamers to ena...
متن کاملIn vivo protein binding and functional analysis of cis-acting elements in the U3 region of the bovine leukemia virus long terminal repeat.
Bovine leukemia virus (BLV) is a member of the human T-cell leukemia virus (HTLV)/BLV group of retroviruses. These viruses regulate their own transcription by producing Tax, a protein which activates the virus promoter region, the long terminal repeat (LTR). To explore the molecular mechanisms involved in the transactivation, we identified protein binding elements by in vivo footprinting and an...
متن کاملFunctional replacement of the R region of simian immunodeficiency virus-based vectors by heterologous elements.
Substitution of lentiviral cis-acting elements by heterologous sequences might allow the safety of lentiviral vectors to be enhanced by reducing the risk of homologous recombination and vector mobilization. Therefore, a substitution and deletion analysis of the R region of simian immunodeficiency virus (SIV)-based vectors was performed and the effect of the modifications on packaging and transf...
متن کاملcis-acting regulatory regions in the long terminal repeat of simian foamy virus type 1.
Simian foamy virus type 1 (SFV-1), a member of the Spumavirinae subfamily of retroviruses, encodes a transcriptional transactivator (taf) that strongly augments gene expression directed by the viral long terminal repeat (LTR) (A. Mergia, K. E. S. Shaw, E. Pratt-Lowe, P. A. Barry, and P. A. Luciw, J. Virol. 65:2903-2909, 1991). This report describes cis-acting regulatory elements in the LTR that...
