GH and PRL transcripts analyzed in healthy cohorts of four different mouse strains.

<p>Linear regression analyses of PRL (y-axis) and GH (x-axis) transcript levels in brain RNAs from (A) FVB/NCr, (B) C57Bl/6J, (C) B6.I, and (D) FVB-TgMo<i>Prnp</i>^a(4053) mice are presented in the left-hand panels. Covariance (y-axis) versus correlation coefficient plots are shown in the right-hand panels; the co-regulated (outlier) behavior of PRL-GH and chorionic gonadotrophin alpha-chain (CGA) + PRL-GH is indicated within circled data points.
