Prostaglandin F2 alpha (PGF2 alpha) triggers protein kinase C (PKC) and tyrosine kinase activity in cultured mammalian cells.
Prostaglandin F2 alpha (PGF2 alpha) added to confluent resting Swiss 3T3 cells triggers tyrosine kinase (PTK) activation characterized by the phosphorylation of a set of 75, 86, 110 and 140 kD proteins. PGF2 alpha induces this event independently of PKC activation. However, both PKC and PTK activities appear to act concertedly to cause mitogenesis. Here we discuss their relevance in the control of mammalian cell division.
