We also used DDPCR to isolate DESTs from androgen-modulated rat ventral prostate tissue , one of which we characterized and found to correspond to the 3' end of prostatic spermine binding protein mRNA , a known androgen-regulated gene .
 ( RNA: prostatic spermine binding protein mRNA, None) , ( DNA: androgen-regulated gene, None) , ( RNA: 3#$%# end, None) , ( protein: prostatic spermine binding protein, None) , ( DNA: DESTs, None)
