Figure 1

Expression levels of gene encoding TLR4 (relative to GAPDH). The figure reports the gene expression levels of TLR4 in normal or aneurysmatic tissue samples from 51 BAV and 25 TAV cases with AAA. The comparison of data showed significant differences among the four groups with p < 0.0001, by ANOVA test, Bonferroni corrected. Significant also were the levels of TLR4 gene expression by comparing data in normal aorta tissues from BAV and TAV cases (p = 0.0001, by t test, Welch corrected), and between two levels in aneurymatic tissue samples from TAV and BAV groups with AAA (p = 0.0001, by t test, Welch corrected). However, the lowest levels were observed in normal aorta tissues from BAV with AAA, that confirmed their systemic levels of s-TLR4. The statistical significance was detected by using t test and ANOVA test, when appropriate.
