We have previously demonstrated that hybrid adeno-associated viral (AAV) vectors bearing nonhomologous inverted terminal repeats (ITRs) enhance directional intermolecular recombination and the efficiency of dual-AAV vector trans-splicing in cultured cells. Using hybrid-ITR vectors carrying two exons of a lacZ minigene, we demonstrate that this dual-vector(More)
The expression of the alpha-myosin heavy chain (MHC) gene is restricted primarily to cardiac myocytes. To date, several positive regulatory elements and their binding factors involved in alpha-MHC gene regulation have been identified; however, the mechanism restricting the expression of this gene to cardiac myocytes has yet to be elucidated. In this study,(More)
In the presence of complementing adeno-associated virus type 2 (AAV-2) Rep proteins, AAV-2 genomes can be pseudotyped with the AAV-5 capsid to assemble infectious virions. Using this pseudotyping strategy, the involvement of the ubiquitin-proteasome system in AAV-5 and AAV-2 capsid-mediated infections was compared. A recombinant AAV-2 (rAAV-2) proviral(More)
The relatively small package capacity (less than 5 kb) of adeno-associated virus (AAV) vectors has been effectively doubled with the development of dual-vector heterodimerization approaches. However, the efficiency of such dual-vector systems is limited not only by the extent to which intermolecular recombination occurs between two independent vector(More)
Tripeptidyl aldehyde proteasome inhibitors have been shown to effectively increase viral capsid ubiquitination and transduction of recombinant adeno-associated virus type 2 (rAAV-2) and rAAV-5 serotypes. In the present study we have characterized a second class of proteasome-modulating agents (anthracycline derivatives) for their ability to induce rAAV(More)
Recombinant adeno-associated virus type 5 (rAAV-5) is known to efficiently transduce airway epithelia via apical infection. In contrast, rAAV-2 has been shown to be inherently ineffective at transducing airway epithelia from the apical surface. However, tripeptide proteasome inhibitors (such as LLnL) can dramatically enhance rAAV-2 transduction from the(More)
We previously reported that spliceosome-mediated RNA trans-splicing (SMaRT), using recombinant adeno-viral vectors expressing pre-trans-splicing molecules (PTMs), could partially restore cystic fibrosis trans-membrane conductance regulator (CFTR) chloride channel activity to polarized human ⌬F508 CF airway epithelia. Although these studies proved that SMaRT(More)
The choice of adeno-associated virus serotypes for clinical applications is influenced by the animal model and model system used to evaluate various serotypes. In the present study, we sought to compare the biologic properties of rAAV2/1, rAAV2/2, and rAAV2/5 transduction in polarized human airway epithelia using viruses purified by a newly developed common(More)
Recombinant adeno-associated virus (rAAV) vectors possess the unique ability to introduce genetic alterations at sites of homology in genomic DNA through a mechanism thought to predominantly involve homologous recombination. We have investigated the efficiency of this approach using a mutant enhanced green fluorescent protein (eGFP) fluorescence recovery(More)
Aim of this article is to clarify the potential use of EEG signal in modern information age. The basic principle of Brain Computer Interface (BCI) lies in the connection of brain waves with output device through some interface. BCI technology represents a communication interface between brain and computer. To sense electric signal from the brain, it is(More)
