a-Helical Corticotropin Releasing Factor (12-41) is a 30 amino acids long, α-helical analogue of corticotropin releasing factor/hormone. Corticotropin releasing factor (CRF) is a hypothalamic hormone, which stimulates the secretion of adrenocorticotrophic hormone (ACTH). a-Helical Corticotropin Releasing Factor (12-41) would suppress the stimulatory effect[1][2]. | [in vivo]
a-Helical Corticotropin Releasing Factor (12-41) (15-150 μg; s.c.; isolated for 30 or 60 min) suppresses the active behavioral response characteristic of guinea pig pups to brief isolation in novel surroundings[1].
| Animal Model: | Guinea pig pups (20-26 days old and )[1] | | Dosage: | 15, 50, 150 μg per animal | | Administration: | Subcutaneous injection; isolated in novel surroundings for 30 min or 60 min. | | Result: | Resulted pups vocalized more and exhibited more locomotor activity in 20- to 26-day-old pups.
Increased levels of vocalizing in isolated 4- to 6-day-old pups at 50 μg dose, though no changes were seen in locomotor activity. |
