CD13/APN induction is modulated by inhibitors of signaling intermediates.
KS1767 cells in 1% serum were incubated with (+) or without (−) bFGF and the indicated chemical inhibitors of signal transduction intermediates: PD98059, MEK inhibitor; wortmannin, PI-3K inhibitor; and manumycin A, Ras inhibitor. Total cellularCD13/APN mRNA or control 28S levels were assessed after 24 hours.
