Effect of NBQX
(10 mg/kg, ip) and rapamycin (15 mg/kg, ip) on the phosphorylation
of Akt, ERK, mTOR, and GluA1ser845 in the PFC of mice. PFC samples
of 4 native mice were collected 1 h after last injection. (A) Western
blot analysis of pAkt, pERK, pmTOR, and pGluA1ser845 was performed.
Results showed the significantly increased expressions of (B) pAkt,
(D) pmTOR, and (E) pGluA1ser845 in mice prefrontal cortex following
vanillic acid treatment, but the change of (C) pERK did not achieve
statically significant. Note that the increased expressions of (B)
pAkt, (D) pmTOR, and (E) pGluA1ser845 resulted from vanillic acid
treatment are blocked when mice were pretreated with NBQX. The increased
expression of (D) pmTOR resulted from vanillic acid treatment is blocked
when mice were pretreated with rapamycin and the increased expressions
of (B) pAkt and (E) pGluA1ser845 resulted from vanillic treatment
are not blocked. [pAkt, F(3,12) = 7.564, p < 0.01; pERK, F(3,12) = 2.399, p > 0.05; pmTOR, F(3,12) = 4.714, p < 0.05; pGluA1ser845, F(3,12) = 34.337, p < 0.001; n = 4 per group; *p < 0.05; **p < 0.01, ***p < 0.001, comparison to saline + saline group with the
Tukey post-hoc analysis]. Total levels of Akt, ERK, mTOR, and GluA1ser845
were not different among the four groups. Values shown are mean ±
SEM.
