On the other hand, contrast-enhanced imaging (Fig. 3b) illustrated peripheral rim enhancement of live tumor (13.49 ± 4.85 g for Ad-CMV-HA-SSTR2 + A II, 15.49 ± 8.37 g for Ad-CMV-HA-SSTR2, and 14.99 ± 7.64 g for Ad-CMV-GFP; mean ± SD) and lack of enhancement of the necrotic center (22.61 ± 6.94 g for Ad-CMV-HA-SSTR2 + A II, 27.38 ± 21.21 g for Ad-CMV-HA-SSTR2, and 14.50 ± 1.29 g for Ad-CMV-GFP; mean ± SD). This evidence concerns the gene SSTR2 and neoplasm.
