Photoperiod regulates genes encoding melanocortin 3 and serotonin receptors, and secretogranins expressed in the dmpARC of the Siberian hamster

ABSTRACT: The mechanism(s) involved in the regulation of the seasonal-appropriate body weight of the Siberian hamster is currently unknown. We have identified photoperiodically regulated genes including VGF in a sub-region of the arcuate nucleus termed the dorsomedial posterior arcuate (dmpARC). Gene expression changes in this nucleus so far account for a significant number of those reported as photoperiodically regulated and are therefore likely to contribute to seasonal physiological responses of the hamsters. The present study was conducted to identify additional genes expressed in the dmpARC regulated by photoperiod that could be involved in regulating the activity of this nucleus with respect to seasonal physiology of the Siberian hamster.
