  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In ad libitum fed mice, intraperitoneal GHRP‑6 did not alter circadian phase.

    In plain wordsIn mice with free access to food, GHRP‑6 did not change the timing of the body clock.

    Summary
    In vivo, intraperitoneal administration of ghrelin or a synthetic analog, growth hormone-releasing protein-6 (GHRP-6), to ad libitum fed animals failed to alter circadian phase.

    Summary · context
    We examined the response of the SCN to ghrelin treatments in vitro, by means of electrophysiological and bioluminescence recordings, and in vivo, by assessing effects on the phase of locomotor activity rhythms.
  2. 02AnimalAnimal study (in vivo)Efficacy outcome

    In mice injected after 30 h of food deprivation, GHRP‑6 induced a phase advance compared with saline.

    In plain wordsIn mice that went without food for 30 hours, GHRP‑6 moved the body clock earlier than saline did.
