FMO3/DMBT1 expression level in paired tubal and endometrial tissue samples. Comparisons of mRNA expression levels in the fallopian tube and the endometrium by quantitative PCR in 21 paired samples (pooled data): FMO3 was significantly higher in the fallopian tube than that in the endometrium (a, P<0.001); whereas DMBT1 showed a complete reverse pattern (b, P<0.001). Comparisons of protein level of expression in the fallopian tube and the endometrium by western blots in two representative paired cases (c, d). Similarly, FMO3 was higher in the fallopian tube than the endometrium (c, P=0.006), whereas DMBT1 was higher in the endometrium (d, P=0.001). The western bands were in the lower panel, whereas the bar graphs reflected the bands density after balanced with the GAPDH control. Each experiment was conducted three times, and the data were expressed as mean±s.e.m. *Statistically significant by comparing with the paired cases. E, endometrium; FT, fallopian tube.
