Herwig A, Wilson D, Logie TJ, Boelen A, Morgan PJ, Mercer JG, Barrett P. Photoperiod and acute energy deficits interact on components of the thyroid hormone system in hypothalamic tanycytes of the Siberian hamster. Am J Physiol Regul Integr Comp Physiol 296: R1307–R1315, 2009. First published March 18, 2009; doi:10.1152/ajpregu.90755.2008 (http://ajpregu.physiology.org/cgi/content/full/296/5/R1307).

In the original Figure 1A, the lower left panel was mistakenly a copy of the one on the lower right. The corrected figure appears below with its original legend.

Quantification of type II (D2) and III (D3) deiodinase (Dio2 and Dio3) mRNA expression in the 3rd ventricular tanycyte layer of Siberian hamster in long-day (LD) or short-day (SD) photoperiod with or without 48 h of starvation. A and C: representative autoradiographs of coronal brain sections from each of the 4 treatment conditions hybridized with a probe for Dio2 and Dio3. B and D: quantification of autoradiograph signals for Dio2 and Dio3 mRNA expression. Expression was normalized to the highest value obtained for each probe. Solid bars, ad libitum-fed hamsters; gray bars, fold-restricted (48-h-starved) animals. *P < 0.05; ***P < 0.001 by 2-way ANOVA and Tukey's post hoc test for Dio2 and by t-test for Dio3.

Quantification of VGF, neuropeptide Y (NPY), and thyrotropin-releasing hormone (TRH) mRNA expression in the hypothalamus of the Siberian hamster. A: representative autoradiographs of coronal brain sections from each of the treatment conditions hybridized with a probe for VGF. B: quantification of VGF mRNA expression in the dorsal region of the medial posterior area of the arcuate nucleus (dmpARC) of hamsters in the SD photoperiod (no expression in LD) with and without 48 h of starvation. C: autoradiographs of coronal brain sections from each of the treatment conditions hybridized with a probe for NPY. D: quantification of NPY expression in the arcuate nucleus of hamsters held in LD and SD photoperiods with and without 48 h of starvation. E: autoradiographs of coronal brain sections from each of the treatment conditions hybridized with a probe for TRH. F: quantification of TRH mRNA expression in the paraventricular nucleus. Expression was normalized to the highest value for each probe. Solid bars, ad libitum-fed hamsters; gray bars, starved hamsters. *P < 0.05; ***P < 0.001 by 2-way ANOVA and Tukey's post hoc test.
