Title: Melatonin Increases Serum Insulin-Like Growth Factor-I in Male Syrian Hamsters*
Abstract: Male Syrian hamsters maintained on a 14-h light, 10-h dark photoperiod were injected once daily (1-2 h before lights out) with melatonin (25 μg), once every other day with Tα (5 fig every other day), or melatonin every day plus T4 every other day. Hamsters which received melatonin injections, with or without T4, had serum levels of insulin-like growth factor that were increased 2-fold. The results suggest that melatonininduced changes in body weight are a result of long-term changes in insulin-like growth factor-I secretion. (Endocrinology122: 2558–2561, 1988)
