Fig 2: Immunohistochemical detection of FAAH, PIR and TAF5L protein levels in primary invasive breast tumors (A-C).

Fig 3: Immunohistochemical staining for the EC-degrading enzymes ABHD2, FAAH and MGLL in the human testis. The images on the left show a general expression pattern and the images on the right show a higher magnification of an area within a stippled line. All pictures show a low magnification image of negative controls in the right upper corner. Note that the ABHD2 (top images) is expressed in the cytoplasm of all stages of germ cell maturation, except early spermatocytes. FAAH reaction (middle row) is strongest in post-meiotic germ cells, including late spermatocytes and spermatids. MGLL protein (bottom images) is abundant in Sertoli cells. L (leptotene) and P (pachytene) indicate early and late spermatocytes, respectively.

Fig 4: Kaplan-Meier depicting disease-specific survival in breast cancer according to expression patterns of GGH, FAAH, PIR and TAF5L (A-D). Dashed line represents patients whose tumors expressed GGH (A), FAAH (B), PIR (C) and TAF5L (D). Solid line represents patients whose tumors did not express GGH (A-D). The p-values for the difference between the curves were calculated using log-rank test.
