From: Insulin-like growth factor (IGF)-I obliterates the pregnancy-associated protection against mammary carcinogenesis in rats: evidence that IGF-I enhances cancer progression through estrogen receptor-α activation via the mitogen-activated protein kinase pathway

Groups Body weight (g) at MNU injection (mean ± SEM) Body Wt. (g) at Sacrifice (mean ± SEM)
P-Un 286 ± 3.2 (n = 7) 303 ± 3.5 (n = 6)
P-IGF-I 286 ± 6.2 (n = 7) 317 ± 4.5 (n = 6)
AMV 293 ± 5.4 (n = 7) 309 ± 9.6 (n = 6)
  1. Body weight at the time of N-methyl-N-nitrosourea (MNU) injection and just before the animals were killed at the termination of the experiment for untreated parous rats (P-Un), parous rats treated with insulin-like growth factor-I (P-IGF-I), and untreated virgin rats that were age matched with the parous animals (AMV).
