Differential involvement of ERK1-2 and p38MAPK activation on Swiss 3T3 cell proliferation induced by prostaglandin F2α
Prostaglandin F2α (PGF2α) induces cyclin D1 expression and DNA synthesis in Swiss 3T3 cells. In order to assess which signaling mechanisms are implicated in these processes, we have used both a pharmacological approach and interfering mutants. We demonstrate that PGF2α induces extracellular-signal-r...
