From: 7α-Hydroxypregnenolone, a key neuronal modulator of locomotion, stimulates upstream migration by means of the dopaminergic system in salmon

Figure 4

Comparisons of Cyp7b mRNA expression and 7α-OH PREG synthesis among different brain regions of chum salmon Oncorhynchus keta.

Male salmon captured at the pre-spawning ground during upstream migration were used. Each column and vertical line represent the mean ± s.e.m. of six independent samples. *P < 0.05 or **P < 0.01 versus pituitary gland.
