Kat Publishes Manuscript in Hormones and Behavior

Kat’s manuscript on the role of adrenal melatonin type 1 (MT1) receptors in regulating seasonal plasticity in social behavior was recently published in Hormones and Behavior! In this study, Kat showed that overexpressing MT1 receptors in the adrenal glands and exposure to short-day (SD) photoperiods caused similar changes in social behavior, including increased aggression and decreased investigation and self-grooming, in male hamsters. Conversely, timed melatonin administration, but not adrenal MT1 overexpression, was necessary to induce SD-like reductions in body and reproductive tissue mass. Taken together, her results suggest that adrenal MT1 receptor signaling modulates social behavior, but not energetics or reproduction in seasonally breeding species.
