Antisense display: a new method for functional gene screen and its application to angiogenesis-related gene isolation.
2006
: We have developed an antisense-oriented method for functional gene screening, which we termed “antisense display.” After evaluation in a cell-free system, we applied this method to a cellular system for isolating angiogenesis-related genes and came across a gene previously not described in humans. A screen of 10 mer antisense repertoire led to the identification of a unique ‘angiostatic’ antisense, and the gene corresponding to it was found to be preferentially expressed in vascular endothelial cells, coding for a putative type-2 membrane protein containing Rab-GAP/TBC and EF-hand-like domains. We named it vascular Rab-GAP/TBC domain-containing protein (VRP). The results obtained thus indicate that the antisense display method is useful for the isolation of functional genes responsible for phenotypes concerned.
