Phosphorylation of Akt,
JNK, and p38 MAP kinases in human primary
PBMC. (A) Time-courses with HU308 (1 μM) and vehicle control.
For p-Akt and p-p38 time-points 10–30 min are significantly
different from time-matched vehicle controls (p <
0.0001–0.0002; two-way RM ANOVA with Holm-Šídák
posthoc test). For p-JNK, all points are indistinguishable from 0
min (p = 0.988; one-way ANOVA). The graph shows mean
± SEM of three independent experiments performed in technical
triplicate, each with cells from a separate subject (three subjects
in total). (B) Responses to 20 min 1 μM HU308 after pretreatment
with PTX, gallein, or vehicle control. Data are normalized and statistically
compared to the corresponding vehicle plus HU308 control by two-way
RM ANOVA with Holm-Šídák posthoc test. The graph
shows independent experiment means (from technical triplicate) as
well as overall mean ± SEM of these three independent experiments
each performed with cells from a separate subject (three subjects
in total).
