A brief exposure of quiescent (Go) WI-38 human fibroblasts to the tumor promoter TPA results in an increase in the mRNA levels of c-fos protooncogene. The same effect is produced by exposing to TPA human diploid fibroblasts WI38 synchronized in S phase by treatment with 2.5 mM hydroxyurea. Induction of c-fos mRNA in response to TPA occurs also during the progression of synchronized WI38 throughout the second and third cell cycle, but it is not associated with measurable changes in the cell cycle progression of these cells. These findings suggest that TPA induction of c-fos mRNA levels in proliferating cells is a stimulus specific rather than a function specific event.

Abstract
A brief exposure of quiescent (Go) WI-38 human fibroblasts to the tumor promoter TPA results in an increase in the mRNA levels of c-fos protooncogene. The same effect is produced by exposing to TPA human diploid fibroblasts WI38 synchronized in S phase by treatment with 2.5 mM hydroxyurea. Induction of c-fos mRNA in response to TPA occurs also during the progression of synchronized WI38 throughout the second and third cell cycle, but it is not associated with measurable changes in the cell cycle progression of these cells. These findings suggest that TPA induction of c-fos mRNA levels in proliferating cells is a stimulus specific rather than a function specific event.
