title: Expression and regulation of prostaglandin F receptor mRNA in rodent osteoblastic cells.
abstract: The ability of prostaglandins to inhibit collagen synthesis and induce prostaglandin G/H synthase in bone cells appears to be mediated by the prostaglandin F2 alpha receptor (FPR). We have identified FPR mRNA in the osteoblastic cell lines, Py1a from rats and MC3T3-E1 from mice, as well as in the stem cell cultures, MN-7 and mouse marrow, using reverse transcriptase-polymerase chain reaction technology (RT-PCR). Expression of FPR mRNA was increased in Pyla, MN-7 and marrow cells with prolonged culture or dexamethasone treatment and decreased after treatment with fluprostenol, a selective FPR agonist.
