This study analyzed whether trefoil factor 3 (TFF3) is locally elevated and correlated with common biomarkers and inflammatory processes in endometriosis. Peritoneal fluid (PF) was obtained from 50 women and serum from 124 women with or without endometriosis. Experimental endometriosis was induced in female C57BL/6 mice by syngeneic transplantation of uterine tissue to the abdominal wall. Levels of TFF3 in PF of women with endometriosis were significantly increased ( P < .05) and correlated with local levels of known biomarkers for endometriosis: cancer antigen (CA) 125, CA-19-9, interleukin 8, monocyte chemotactic protein 1, and matrix metalloproteinase 7. Serum levels of TFF3 in women were significantly influenced by the menstrual cycle but were independent from disease state. In mice, local TFF3 levels were significantly elevated in early endometriosis (up to 4 weeks after transplantation, P < .001) and corresponded to increases in spleen weight as marker for systemic inflammation. This study provides the first evidence that TFF3 is locally elevated in the peritoneal cavity in endometriosis and might play a role in disease pathogenesis and its associated inflammatory processes. Furthermore, the results show that TFF3 is regulated through the menstrual cycle. With respect to animal models, syngeneic mouse model does reflect local TFF3 upregulation in the peritoneal cavity affected by endometriosis. |
