FAAH and carcinosarcoma: Histomorphometric analysis of these data confirmed the visual staining patterns in the glands alone, the stroma alone, or when the glands and stroma were combined (Figure 3B), with FAAH protein levels (measured as H-score) in the glands and stroma combined (right panel) being significantly lower (P < 0.0001) in all the various grades of type 1 [grade 1 (172.9 ± 0.76), grade 2 (169.5 ± 0.64), and grade 3 (120.3 ± 2.23)] and type 2 EC [serous (146.5 ± 1.94) and carcinosarcoma (39.18 ± 2.50)] compared to the atrophic control tissue (383.3 ± 1.10).
