*2.5. Statistical Analysis*

Unless otherwise indicated, all the values are expressed as a mean ± standard error of the mean (SEM) as %bl, and compared by analysis of variance (SigmaStat 3.5, Systat Software Inc., San Jose, CA, USA). If the F values were significant, Student-Newman-Keuls (SNK) post-hoc tests were conducted. Comparisons of only two groups were conducted with unpaired Student t-tests. All the results were considered statistically significant at *P* < 0.05 (2-tailed): \*vs. Con (0 μM TZD).
