Table 1. Effect of treatment with GHRH antagonists JMR-132 (10 μg/day) and JV-1-38 (20 μg/day) on tumor weight and on tumor burden in PC3 cells xenografted into nude mice.

Treatment groups and the number of evaluable animals	Tumor weight, mg (% inhibition)	Tumor burden, μg/g body weight (% inhibition)
Control (n = 10)	756 ± 101	24.59 ± 3.26
JMR-132 (n = 6)	235 ± 140 (68)*	10.15 ± 4.08 (58)*
JV-1-38 (n = 6)	270 ± 102 (64)*	8.40 ± 3.08 (66)*

Values are mean ± SE.

^*P < 0.05 vs. Control.
