  1. Values were obtained from the average of duplicate PCRs run on the same gel and assays were repeated three times for each gene, using a fresh cDNA sample each time. Values are presented as mean ± SEM, n = 3. a Values were obtained by dividing the calculated intensity of 5αR1 or HSO bands (27 cycles) by the calculated intensity of the 18S band (12 cycles). b Values were obtained by dividing the calculated intensity of 5αR2 bands (33 cycles) by the calculated intensity of the 18S band (12 cycles). c Values obtained from very faint bands, calculated as <0.1, were adjusted to 0.1.
