Retroviral insertional mutagenesis: tagging cancer pathways.
Slow transforming retroviruses, such as the Moloney murine leukemia virus (M-MuLV), induce tumors upon infection of a host after a relatively long latency period. The underlying mechanism leading to cell transformation is the activation of proto-oncogenes or inactivation of tumor suppressor genes as a consequence of proviral insertions into the host genome. Cells carrying proviral insertions th...
متن کاملRetroviral insertional mutagenesis identifies genes that collaborate with NUP98-HOXD13 during leukemic transformation.
The t(2;11)(q31;p15) chromosomal translocation results in a fusion between the NUP98 and HOXD13 genes and has been observed in patients with myelodysplastic syndrome (MDS) or acute myelogenous leukemia. We previously showed that expression of the NUP98-HOXD13 (NHD13) fusion gene in transgenic mice results in an invariably fatal MDS; approximately one third of mice die due to complications of se...
متن کاملAAV and Insertional Mutagenesis.
editorial I n this issue of Molecular Therapy, David Rus-sell provides an invited commentary on data presented at the tenth annual meeting of the American Society of Gene Therapy that strongly suggested that adenovirus-associated virus (AAV) vector insertion could in certain models be linked to the development of cancer. 1 A short report describing the data that are the subject of this commenta...
متن کاملRetroviral Elements and Their Hosts: Insertional Mutagenesis in the Mouse Germ Line
The inbred mouse is an invaluable model for human biology and disease. Nevertheless, when considering genetic mechanisms of variation and disease, it is important to appreciate the significant differences in the spectra of spontaneous mutations that distinguish these species. While insertions of transposable elements are responsible for only approximately 0.1% of de novo mutations in humans, th...
متن کاملTumor suppressor gene identification using retroviral insertional mutagenesis in Blm-deficient mice.
Retroviral insertional mutagenesis preferentially identifies oncogenes rather than tumor suppressor (TS) genes, presumably because a single retroviral-induced mutation is sufficient to activate an oncogene and initiate a tumor, whereas two mutations are needed to inactivate a TS gene. Here we show that TS genes can be identified by insertional mutagenesis when the screens are performed in Blm-d...
