Abstract:
Frequent modification such as a point mutation or a deletion of a DNA inserted into retrovirus DNA vector is observed. Activation of onco gene in retroviral genome might be caused by such mechanisms.
Insights
Frequent DNA modifications in retroviral vectors, like point mutations and deletions, may activate oncogenes. This research explores the mechanisms behind these genetic alterations and their potential oncogenic consequences.
