CT values and geometric means of housekeeping genes

Gene	Wild-type basal	Ccr2 knockout basal	Wild-type pilocarpine	Ccr2 knockout pilocarpine
HPRT1	22.9 ± 0.1	22.7 ± 0.2	25.9 ± 0.5	27.1 ± 0.5
β-actin	21.3 ± 03	21.0 ± 0.3	21.1 ± 0.4	20.4 ± 0.3
GAPDH	18.6 ± 0.3	18.3 ± 0.1	19.2 ± 0.2	19.6 ± 0.3
Geometric mean	20.8 ± 0.2	20.7 ± 0.2	21.9 ± 0.2	22.1 ± 0.2

Data are the mean ± SEM in four groups of mice (n = 6 wild-type basal, n = 6 Ccr2 knockout basal, n = 18 wild-type pilocarpine, and n = 11 Ccr2 knockout pilocarpine) 4 d after treatment with pilocarpine or saline solution.
