Abstract
Infection of confluent monolayer cultures of African green monkey kidney cells with simian virus 40 results in an enhanced synthesis of nuclear and mitochondrial DNA. This is demonstrated both by an increased rate of incorporation of [(3)H]thymidine into mitochondrial DNA and by detection of increased amounts of mitochondrial DNA in infected cells. With monkey BSC-1 cells, where SV40 infection does not result in a stimulation of nuclear DNA synthesis, no stimulation of mitochondrial DNA synthesis is observed. SV40 infection of mouse 3T3 cells also stimulates nuclear and mitochondrial DNA synthesis.
