further evaluation of the antagonistic interaction of the tgfs revealed it to be dose-dependent in that maximally effective doses of tgf alpha ( 10 ng/ml ) partially overcame the stimulation of aromatase activity brought about by relatively low ( less than 0.3 ng/ml ) but not higher ( greater than 1 ng/ml ) concentrations of tgf beta , thereby shifting the tgf beta dose-response curve to the right .
