this is seemingly due to differential regulation of fos gene expression , not only at the transcriptional and/or post-transcriptional level ( transient or sustained fos rna induction by egf or tgf beta in el2 cells ) , but also at the translational level ( fos protein ( s ) induction by tgf beta in el2 but not nih-3t3 fibroblasts , possibly related to the stimulatory vs inhibitory effect of this factor on the growth of the former vs the latter line ) .
