New antidepressant mechanism of Yueju Pill: Increasing ghrelin level by inhibiting gastric mTOR/S6K signaling pathway and sensitizing hippocampal GHS-R.

ABSTRACT:

Background and aim

Yueju Pill (YJ) not only has good antidepressant effect but also can effectively treat digestive system diseases. However,it remains unclear whether the mechanism of antidepressant action of YJ is related to the peripheral digestive system. The purpose of this study was to elucidate the antidepressant mechanism of YJ on ghrelin level based on gastric mTOR/S6K signal pathway and sensitized hippocampal Ghrelin/GHS-R system in CUMS mice.

Experimental procedure

The depression model was induced by chronic unpredictable mild stress (CUMS) and social isolation. The antidepressant effect of YJ was observed by behavioral experiment and hemodynamic experiments. Ghrelin levels in in hippocampus and blood were measured by Elisa kit, and the mRNA of ghrelin in mice sto
