(a) Northern blot of Ucp1 mRNA expression in wt and Per1−/−;Per2m/m BAT in 24hr LD cycles. (b) A summary of three independent Northern blot analyses described in (a) (±SEM). (c) Ucp1 mRNA expression in wt and Per1−/−;Per2m/m BAT in 24hr DD cycles. (d) A summary of three independent Northern blot analyses described in (c) (±SEM). (e) Per2 and Bmal1 expression in wt and Per1−/−;Per2m/m BAT in 24hr LD cycles. Summaries of (f) Per2 and (g) Bmal1 mRNA expression in 24hr LD cycles from three independent experiments (±SEM). (h) Per2, Bmal1 and Ucp1 mRNA expression in BAT from untreated (Control) wt mice and wt mice treated with one cycle of jet-lag (Shift). (i) A summary of three independent Northern blot analyses described in (h) (±SEM). (j) Ucp1 mRNA expression in BAT from age-matched control wt mice and wt mice treated with 10 months of chronic jet-lag. (k) A summary of Ucp1 mRNA expression from three independent Northern blot analyses described in (j).
