A bicistronic retrovirus vector containing a picornavirus internal ribosome entry site allows for correction of X-linked CGD by selection for MDR1 expression.

Chronic granulomatous disease (CGD) is an inherited hematologic disorder involving failure of phagocytic cell oxidase to produce superoxide (O2-.), resulting in recurrent infections. The success of retrovirus gene therapy for hematopoietic diseases will be limited both by the efficiency of ex vivo transduction of target cells and by the ability of corrected cells to replace uncorrected cells in...

Development of a rubella virus vaccine expression vector: use of a picornavirus internal ribosome entry site increases stability of expression.

Rubella virus (RUB) is a small plus-strand RNA virus classified in the Rubivirus genus of the family Togaviridae. Live, attenuated RUB vaccines have been successfully used in vaccination programs for over 25 years, making RUB an attractive vaccine vector. In this study, such a vector was constructed using a recently developed RUB infectious cDNA clone (Robo). Using a standard strategy employed ...

Use of an internal ribosome entry site for bicistronic expression of Cre recombinase or rtTA transactivator.

Conditional gene targeting depends on tissue and time specificity of recombination events. Endogenous promoters are often used to drive various transgenic constructs. To avoid the problems associated with reconstituting a specific expression pattern in transgenic animals by this method, we tested the internal ribosome entry site of the encephalomyocarditis virus, to enable linkage of the Cre re...

Duck Hepatitis A virus possesses a distinct type IV internal ribosome entry site element of picornavirus.

Sequence analysis of duck hepatitis virus type 1 (DHV-1) led to its classification as the only member of a new genus, Avihepatovirus, of the family Picornaviridae, and so was renamed duck hepatitis A virus (DHAV). The 5' untranslated region (5' UTR) plays an important role in translation initiation and RNA synthesis of the picornavirus. Here, we provide evidence that the 651-nucleotide (nt)-lon...

Absence of internal ribosome entry site-mediated tissue specificity in the translation of a bicistronic transgene.

The 5' noncoding regions of the genomes of picornaviruses form a complex structure that directs cap-independent initiation of translation. This structure has been termed the internal ribosome entry site (IRES). The efficiency of translation initiation was shown, in vitro, to be influenced by the binding of cellular factors to the IRES. Hence, we hypothesized that the IRES might control picornav...
