Figure 2From: Enhancement of catecholamine release from PC12 cells by the traditional Japanese medicine, rikkunshito Rikkunshito increases TH and VIP mRNA levels. PC12 cells were treated with forskolin alone or in combination with rikkunshito for 6 h. The expression levels of TH mRNA (A) and VIP mRNA (B) were normalized relative to the expression level of G3PDH mRNA. Data are presented as the mean ± SEM of triplicate independent experiments. *, p < 0.05 vs. 0% rikkunshito at each forskolin concentration tested, two-tailed Student’s t-test.Back to article page
