Effect of IGF-I gene therapy on serum PRL levels. Serum PRL was measured in blood samples serially taken from Experimental day -23 to Experimental day 7. The number of rats used was 5 for all groups except for group E₂ + RAd-IGF-I where 7 animals were assessed Asterisks indicate significant differences from serum PRL on experimental day 0 (vector injection); *: P < 0.05; **: P < 0.01. Other details are as in Fig. 3
