Abstract
A screening method for identifying new drugs A screening method for identifying a candidate to drug wherein said method 5 comprises the following steps: a) obtaining an expression vector which comprises a gene sequence codifying a naturally occurring pathogenic non-discriminating tRNA synthetase; b) transforming isolated mammalian cells with the expression vector; c) growing the recombinant cells resulting from (b) in a nutrient medium under conditions which allow the expression of the 10 pathogenic tRNA synthetase, resulting the expression of the pathogenic tRNA synthetase into cell death or a decrease in the rate of cell division; d) providing a substance to be tested; and e) analyzing the resulting cell growth, wherein if there is an increase in cell growth, then the substance selectively inhibits the activity of the pathogenic tRNA synthetase and does 15 not affect to its cellular ortholog, resulting that said substance is a candidate to drug.
