Figure 3. Analysis of PC activity in endocervical swabs collected from post-menopausal control women and patients with different types of endometrial cancer.

A. PC activity in control (n = 6), endometrioid adenocarcinoma (n = 12) and other types of endometrial cancer (n = 1-2 per type) patients. PC activity was significantly higher in endometrioid adenocarcinoma compared to controls, **p=0.0067. Data are expressed in log scales. B. Comparison of PC activity between control (n = 6) and all endometrial cancer analyzed as one group (n = 19). PC activity in endocervical swabs was significantly higher in cancers than controls, ***p=0.0001. C. Comparison of protein concentration between the two groups shown in B. D. The PC activity normalized to total protein concentration was also significantly higher in cancers than controls, **p=0.004.
