1 The synergistic activation of Raf-1 kinase by phorbol myristate acetate and hydrogen peroxide in NIH3T3 cells. Tetradecanoylphorbol Acetate v-raf-leukemia viral oncogene 1 Mus musculus
2 We have previously demonstrated that a 33kDa C-terminal fragment of c-Raf-1 underwent a mobility shift in response to hydrogen peroxide (H(2)O(2)) and phorbol myristate acetate (PMA), respectively. Tetradecanoylphorbol Acetate v-raf-leukemia viral oncogene 1 Mus musculus
3 We have previously demonstrated that a 33kDa C-terminal fragment of c-Raf-1 underwent a mobility shift in response to hydrogen peroxide (H(2)O(2)) and phorbol myristate acetate (PMA), respectively. Tetradecanoylphorbol Acetate v-raf-leukemia viral oncogene 1 Mus musculus
4 Interestingly, H(2)O(2) produced synergistic increase of PMA-stimulated Raf-1 kinase activation after simultaneous treatment of PMA and H(2)O(2). Tetradecanoylphorbol Acetate v-raf-leukemia viral oncogene 1 Mus musculus
5 Interestingly, H(2)O(2) produced synergistic increase of PMA-stimulated Raf-1 kinase activation after simultaneous treatment of PMA and H(2)O(2). Tetradecanoylphorbol Acetate v-raf-leukemia viral oncogene 1 Mus musculus
6 Taken together, our data suggest that the synergistic activation of Raf-1 kinase in response to PMA and H(2)O(2) occurs via mechanisms that involve an interaction of Raf-1 kinase and PKC-epsilon, along with a transient phosphorylation of both Raf-1 kinase and PKC.

7 Taken together, our data suggest that the synergistic activation of Raf-1 kinase in response to PMA and H(2)O(2) occurs via mechanisms that involve an interaction of Raf-1 kinase and PKC-epsilon, along with a transient phosphorylation of both Raf-1 kinase and PKC.
