A) Representative path tracks in the closed and open arms of the elevated plus maze by 12.5 months old Tg PS1/APPswe and their control wild-type littermate receiving regular drinking water (placebo) and anatabine at a dosage of 10 and 20 mg/Kg/Day in their drinking water are shown. B and C) The histogram represents the total distance travelled and mean velocity of Tg PS1/APPswe mice and their control wild-type littermates receiving regular drinking water (placebo) and anatabine at a dosage of 10 or 20 mg/Kg/Day. ANOVA showed a significant main effect of the genotype for the distance travelled (P<0.008) and mean velocity (P<0.008). Post-hoc comparisons show that Tg PS1/APPswe placebo mice were significantly different compared to their wild-type littermate mice for distance travelled (P<0.027) and velocity (P<0.027). Tg PS1/APPswe mice receiving anatabine at a dosage of 10 or 20 mg/Kg/Day were not significantly different from wild-type mice (P>0.05). D) The histogram represents the average amount of time spent by Tg PS1/APPswe and wild-type mice in open arms of the elevated plus maze. ANOVA reveals a significant main effect of the genotype (P<0.003) and an interaction between genotype and anatabine (P<0.029) for the time spent in the open arm. Post-hoc comparison shows that Tg PS1/APPswe placebo mice spent significantly more time in the open arms than wild-type control mice (P<0.002). Tg PS1/APPswe mice receiving anatabine at a dosage of 20 mg/Kg/Day spent significantly less time in the open arms of the EPM compared to Tg PS1/APPswe receiving regular drinking water (placebo) (P<0.011). Overall, anatabine treated Tg PS1/APPswe and wild-type littermate mice spent the same amount of time in the open arms (P>0.183 and P>0.683). The number of individuals (n) tested in three groups were I) Mice receiving regular drinking water (placebo): wild-type (n = 8) and Tg PS1/APPswe (n = 8); II) Mice receiving anatabine at a dosage of 10mg/Kg/Day: wild-type (n = 10) and Tg PS1/APPswe (n = 8) and III) Mice receiving anatabine at a dosage of 20mg/Kg/Day: wild-type (n = 10) and Tg PS1/APPswe (n = 8).</p> 2015-05-26 15:04:00 anatabine treatment stat ad ps nf Chronic Anatabine Treatment chemical structure similarity Mouse Model β deposits tg Transgenic Mouse Model
