Table 3. Relative expression of GnRH and gonadotropin mRNA with brief photostimulation.

	SD	PT Day 2	PT Day 4	PT Day 10
GnRH	3.46 ± 1.1	3.93 ± 1.3	3.38 ± 0.8	3.62 ± 1.3
FSHβ	3.96 ± 1.6	2.65 ± 0.8	1.55 ± 0.3	4.00 ± 0.8
LHβ	0.23 ± 0.1	0.31 ± 0.1	0.35 ± 0.1	0.15 ± 0.0

Relative real time PCR expression data of gene of interest normalized to HPRT-1 reference gene expression in Siberian hamster ovaries for 14 weeks of short photoperiod exposure (SD), or 2, 4, or 8 days post transfer to LD after 14 weeks of SD exposure (PT Day 2, 4, 8). Data are presented as mean ± SEM; no significant differences were noted between any groups.
