Figure Lengend Snippet: Morin modulated the expression of NMDA receptors in the hippocampus of VaD rats. a the expression levels of NR1 ; b the expression levels of NR2A ; c the expression levels of NR2B ; d the expression levels of NR1 protein; e the expression levels of NR2A protein; f the expression levels of NR2B protein; g protein levels of p-CREB; h protein levels of p-CAMK2A; i protein levels of p-CAMK2D. Protein levels of NR1, NR2A, and NR2B were quantified by ELISA. Data are presented as mean ± SD ( n = 8 per group). Statistical analysis was performed by one-way ANOVA with Tukey’s post-hoc test (data met assumptions of normality and homoscedasticity)/Kruskal-Wallis with Dunn’s test (data did not meet assumptions). * indicates a significant difference from the Sham group; # indicates a significant difference 2VO group; *# indicates a significant difference from both the Sham and 2VO groups, with a p-value of less than 0.05 considered statistically significant

Article Snippet: The phosphorylation status of another key NMDAR downstream effector, CREB at Ser133 (p-CREB), was quantified in hippocampal homogenates using a commercial ELISA kit (Phospho-CREB [Ser133] ELISA Kit, Boster Bio, #EKC2382).

Article Title: Δ9-THC increases endogenous AHA1 expression in rat cerebellum and may modulate CB1 receptor function during chronic use

doi: 10.1111/j.1471-4159.2011.07391.x

Figure Lengend Snippet: A. AHA-1 levels in control and AHA-1 transfected HEK293T cells. The cells were transfected with pcDNA 3.1 or AHA-1 (2.25 μg/well in 6-well plates) and serum starved for 24 h. Two days after transfection the cells were lysated and 10 μg of total protein were separated by 10% SDS-PAGE and AHA-1 levels were determined by western blot. B. Modulation of CB1R and CB2R plasma membrane levels by AHA1 overexpression. HEK293T were co-transfected with CB1R or CB2R (0.25 μg/well) and pcDNA 3.1 or AHA-1 (2.25 μg/well each) and after six hours the cells were trypsinized and plated on 12-well plates as described in Material and Methods. FBS was withdrawn for 24 h, and two days after transfection the plasma membrane levels of CB1R and CB2R were determined by ELISA as described in Material and Methods. n=12 in each case from three different transfections. *- indicate p < 0.05 compared to pcDNA 3.1 transfected cells. C. Subcellular localization of CB1R in HEK293T cells. The cells were grown on coverslips in 6-well plates and transfected with 3xHA-CB1R (0.1 μg/well) and DsRed-Rab5 (0.1 μg/well). After serum starvation for 24 h, the cells were fixed and permeabilized. The CB1R localization was stained using HA antibody as described in Material and Methods. Blue: DNA staining by 4,6-diamidino-2-phenylindole (nuclear), green: 3xHA-CB1R, red: DsRed-Rab5. The images are representative from three different coverslips, obtained from three independent transfections. D. CB1R interacts with AHA-1 in HEK293T cells. The cells were transiently co-transfected in 10 mm2 dishes with pcDNA 3.1 (10 μg, control), or with CB1R (5 μg) and pcDNA3.1 (5 μg), or CB1R (5 μg) and AHA-1 (5 μg). After two days the cells were solubilized and immunoprecipitated with CB1R antibody as described under Material and Methods. The immunoprecipitates (20 μg/lane) or the lysates (10 μg/lane) were separated by 10 % SDS-Page and subject to western-blotting with AHA-1 and CB1R antibodies. The experiment shown is representative from three independent transfections.

Article Snippet: The reactions were stopped by medium aspiration and addition of 200 μl thhricloracetic acid. cAMP levels were determined using cAMP Elisa Kit (Cayman Biochemicals) as described in Material and Methods. n=12 in each case from three independent transfections.

Article Title: Δ9-THC increases endogenous AHA1 expression in rat cerebellum and may modulate CB1 receptor function during chronic use

doi: 10.1111/j.1471-4159.2011.07391.x

Figure Lengend Snippet: HEK293T co-transfected with CB1R or CB2R and pcDNA3.1 or AHA1 as in Fig 2B were plated on 24 well-plates and serum straved for 24h. Two days after transfection the medium was changed to PBS containing 100 μM IBMX for one hour. Subsequently, the cells were pretreated with Δ9-THC (1 μM)) for 5 min, followed by stimulation with forskolin (10 μM) for 15 min. The reactions were stopped by medium aspiration and addition of 200 μl thhricloracetic acid. cAMP levels were determined using cAMP Elisa Kit (Cayman Biochemicals) as described in Material and Methods. n=12 in each case from three independent transfections. *- indicates statistically significant differences between pcDNA 3.1 and AHA1 transfected cells by two-way ANOVA followed by Holm Sidak-test (interaction: F(2,12=14.03, p<0.001).
