Abstract: | The phorbol ester tumor promoters induce multiple cellular responses in cell culture, including mitogenesis. We have analyzed 3 variants of mouse 3T3 cells mitogenically unresponsive to the phorbol esters for phorbol ester receptors. All resembled control 3T3 cells in their specific [3H]phorbol 12,13-dibutyrate binding. The variants thus appear to be altered at steps distal to receptor occupancy in the mitogenic response to the phorbol esters. |
