| abstractText | Growth factors induce the sequential expression of cellular genes whose products are thought to mediate long-term responses to the growth factors. In mouse 3T3 fibroblastic cells, the first genes to be expressed (immediate-early genes) are activated within minutes after the addition of platelet-derived growth factor, fibroblast growth factor, or serum. By cDNA cloning, we have identified genes that are activated after a delay of a few hours and several hours prior to serum-induced DNA replication. Activation of these delayed early response genes requires new protein synthesis, presumably the synthesis of immediate-early transcription factors described previously. Partial or complete sequencing of 13 different delayed early cDNAs, representing about 40% of the 650 primary cDNA isolates, revealed that 8 were related to known gene sequences and 5 were not. Among the former are cDNAs encoding nonhistone chromosomal proteins [HMGI(Y) and HMGI-C], adenine phosphoribosyltransferase (APRT), a protein related to human macrophage migration inhibitory factor (MIF), a protein of the major intrinsic protein (MIP) family homologous to the integral membrane protein of human erythrocytes, and cyclin CYL1. In 3T3 cells, the delayed early gene response to growth factors appears to be at least as complex as the immediate-early gene response previously described. |
