- Abstract
- A relatively high mutation rate is probably a major factor in the
evolutionary success of retroviruses, because it generates the
genetic diversity that helps them to cope with changes in the
environment. When using recombinant retroviruses as vectors for
gene transfer and gene therapy, it is important to consider the
implications of this biological characteristic. Until now, the mutation
rate has been studied by using noneukaryotic genes as reporters.
Here we report point mutations in the human glucose-6-phosphate
dehydrogenase (hG6PD) gene transferred by Moloney murine
leukemia virus-based vectors into murine bone marrow cells and
NIH 3T3 murine fibroblasts. After bone marrow transplantation, we
observed an hG6PD with abnormal electrophoretic mobility for 2 out
of 34 mice. Next, we studied this phenomenon quantitatively and
found 1 electrophoretically abnormal hG6PD variant among 93
independently isolated NIH 3T3 clones, from which we estimate a
mutation rate of 1.4 x 10(-5) per base pair per replication cycle.
Mutations in the transferred gene can thus contribute to the
impairment of the effectiveness of retrovirus-mediated gene transfer. (literal)
