Statistical Analysis
Biochemical experiments were repeated three times at least. Values are
reported as the Means±SEM (GraphPad Prism, San Diego, CA). Statistical
comparisions between two groups were analyzed using unpaired two-tailed
t test. Statistical comparisions among multiple groups were conducted
using one-way ANOVA Test (GraphPad Prism, San Diego, CA). Statistical
comparisons for series of data collected at different time points were
conducted by ANOVA tests. All statistical tests were unpaired and
two-tailed.
