Fig.1 - Effect of PrRP treatment (a) or anti-PrRP treatment (b) on pituitary mRNA levels of PRL in goldfish (N = 4-10). Messenger RNA levels were examined by Northern blots and were expressed as the ratio to GAPDH mRNA (arbitrary units). Typical results of Northern blots for each transcript are presented. Significant differences (p < 0.05) are indicated by asterisks. The levels significanlty increased by PrRP treatment but decreased by anti-PrRP treatment.
