Involvement of PKA, CaMKII, PKC, MAPK/ERK and PI3K in the acute antidepressant-like effect of ferulic acid in the tail suspension test

چکیده
Ferulic acid (FA, 4-hydroxy-3-methoxycinnamic acid) is a phytochemical compound naturally present in several plants and foods that is approved as an antioxidant additive and food preservative. It exerts a beneficial action in chronic mild stress-induced depressive-like behavior and produces an acute antidepressant-like effect in the tail suspension test (TST) through the activation of the serotonergic system. This study was aimed at investigating the possible involvement of signaling pathways in the antidepressant-like effect of acute and oral administration of FA, in the TST in mice. The anti-immobility effect of orally administered FA (0.01mg/kg, p.o.) was prevented by pretreatment of mice with H-89 (1μg/site, i.c.v., an inhibitor of PKA), KN-62 (1μg/site, i.c.v., an inhibitor of CaMKII), GF109203X (5ng/site, i.c.v., an inhibitor of PKC), U0126 (5μg/site, i.c.v., an inhibitor of MAPK/ERK) or LY294002 (10nmol/site, i.c.v., an inhibitor of PI3K), all involved with neurotrophic signaling pathways. The results demonstrated that FA exerts antidepressant-like effect in the TST in mice, through the activation of signaling pathways related to neuroplasticity, neurogenesis and cell survival.

Hydroethanolic extract of Carthamus tinctorius induces antidepressant-like effects: modulation by dopaminergic and serotonergic systems in tail suspension test in mice
Objective(s): Studies indicate that major deficiency in the levels of monoaminergic transmitters is a reason for severe depression. On the other hand, it is shown that Carthamus tinctorius L. (CT) may improve neuropsychological injuries by regulation of the monoamine transporter action. Hence, the present study was undertaken to evaluate the involvement of monoaminergic systems in antidepressan...
متن کاملAntidepressant-like effect of zinc is dependent on signaling pathways implicated in BDNF modulation
Considering that intracellular signaling pathways that modulate brain BDNF are implicated in antidepressant responses, this study investigated whether signaling pathway inhibitors upstream to BDNF might influence the antidepressant-like effect of zinc, a metal that has been shown to display antidepressant properties. To this end, the influence of i.c.v. administration of H-89 (1μg/site, PKA inh...
