Examples of retroviral

retroviral
It is not known whether a retroviral insertional event alone is sufficient to initiate transformational changes, or whether additional precipitants are required.
The issue of the integration preferences of retroviral vectors is considered further in the context of insertional mutagenesis below.
Furthermore, it is likely that the retroviral vectors employed for these studies were less than optimal for expression in primitive cells.
Deciphering the molecular mechanisms of integration site selection might have practical applications in improving the safety of retroviral vectors for use in human gene therapy.
Retroviral infection of whole embryos is more efficient than of cultured neural tubes presumably because the viral particles can easily infect neighboring cells.
This limits retroviral infection to dividing cells and can result in poor transduction efficiency in slowgrowing tumours.
Retroviral vectors are the most widely used viral vectors in clinical trials at present.
These include retroviral vectors, adenoviral vectors and adeno-associated viral vectors.
Sequence-targeted retroviral insertion should provide a way to obviate these negative effects in future studies.
Retroviral replication requires the activities of three viral enzymes: reverse transcriptase, integrase and protease.
The electroporation system complements the retroviral system, insofar as it allows for efficient genetic modification of postmitotic cells and mitotic cells.
Attempts to improve the design of retroviral vecto rs have focused on post-transcriptional mechanisms of gene regulation.
The results from about 30 brain tumor patients treated with retroviral-based gene therapy were available at the closure date.
Chromosomal position and activation of retroviral genomes inserted into the germ line of mice.
