Eve-3: A liver enriched suppressor of Ras/MAPK signaling

Abstract

Background/Aims: The developed liver is able to tightly control cellular proliferation, rapidly switching from quiescence to growth in response to specific stimuli. This suggests that growth inhibitors may be involved in the control of liver growth. We analyzed the role of the Spred-family of growth inhibitors in the liver. Methods: We screened human EST databases for Spred-related sequences. Clones were isolated, sequenced, epitope-tagged and expressed. Subcellular localization of clones were determined and their effects on cellular signaling pathways analysed using specific antibodies. Cell cycle progression assays and protein interaction studies were initiated. Organ distribution of trans..
