Expression regulated by Growth Factors/ cytokines
Comment Divergence of intracellular signaling pathways and early response genes of two closely related fibroblast growth factors, FGF8 and FGF18, in bovine ovarian granulosa cells. Jiang Z 2013 et al. Fibroblast growth factors (FGFs) modulate ovarian function, including FGF8 and FGF18. These FGFs activate the same receptors, although FGF18 is unusual in that it increases apoptosis in ovarian granulosa cells whereas the 'typical' response to FGF is increased proliferation. The objective of the present study was to determine which early response genes and pathways are activated by FGF8 and FGF18 in bovine granulosa cells. FGF8 increased abundance of mRNA encoding the FGF-responsive genes SPRY1, SPRY2, SPRY4, NR4A1 and NR4A3 whereas FGF18 did not. FGF8 increased but FGF18 decreased levels of mRNA encoding the growth arrest associated protein, GADD45B. FGF8 increased ERK1/2 phosphorylation but FGF18 did not. Microarray analysis identified EGR1, FOS, FOSL1, BAMBI, XIRP1 and PLK2 as other FGF8 immediate-early response genes, and FGF18 stimulated EGR1, FOSL1, BAMBI and PLK2, but not FOS or XIRP1. This study demonstrates that FGF8 and FGF18 signal through divergent pathways in ovarian granulosa cells, despite reportedly similar receptor activation patterns. /////////////////////////
