Figure 4

Testosterone pretreatment (150 ng/ml, 48 h) triggers an increase in sst2A receptor mRNA expression. At the upper panel are shown the representative autoradiograms from one experiment. At the lower panel are depicted the histograms representing the mean ± SEM of optical densities (ODs) measured on corresponding autoradiograms for each determination performed in three independent experiments (see "Materials and Methods"). C = control; T = testosterone-pretreated (150 ng/ml; 48 h); **: p < 0.01 versus "C".
