Figure 2

FRA protein expression level in paired tubal, endometrial, and ovarian endometriosis samples. Comparisons of protein expression levels of the fallopian tube (FT), the endometrium (E), and the foci of ovarian endometriosis (OE) by Western blot analyses. The figure shows the data from 6 paired samples with number labeled on the top of each panel. The FRA and GAPDH control bands are presented on the top, while the ratio of FRA/GAPDH is illustrated in the bottom for all 6 paired samples. The pooled data are summarized on the right side of the figure. Similar to the gene expression levels, FRA protein was significantly higher in the fallopian tube and the ovarian endometriosis samples than that in the endometrium [*p = 0.103 (FT vs. OE) and **p = 0.001 (E vs. OE)].
