Figure 2From: Acetylcholine content and viability of cholinergic neurons are influenced by the activity of protein histidine phosphataseAcetylcholine content after PHP overexpression. To measure the ACh content of SN56 cells, the cells were harvested 48 h after transfection with the overexpression vectors and ACh was measured by LC-MS/MS. Values are given as means ± standard deviation of 4 experiments. **p < 0.01 compared to H53A-overexpression; n.s. (not significant) compared to GFP-overexpression (ANOVA followed by Scheffé-test). Additionally, p < 0.01 between GFP- and PHP-overexpression was determinedBack to article page
