Androgens alter the molecular response to photic stimulation in the delay phase. Bar graphs depict light-induced mPer1 (A) and mPer2 (B) expression in the SCN of INT, GDX, or GDX+DHT mice after a 30-min LP (LP+) at projected CT13.5 and killed 90 min after the start of the LP. LP−, No LP. mPer1 was induced in all groups, but expression was not altered by any of the treatments. In contrast, mPer2 induction was reduced in GDX animals, compared with both INT and GDX+DHT mice. *, P < 0.05. AU, Arbitrary units.
