Endometriosis is a common chronic estrogen-dependent gynecological disease affecting 10% of women in their reproductive age. It is characterized by proliferation of functional endometrial glands and stroma outside the uterine cavity. In the present study, we used mass spectrometry-based lipidomics to investigate the alterations in serum lipid profiles of mice induced with endometriosis. We identified several dysregulated lipids such as phosphatidylcholines, sphingomyelins, phosphatidylethanolamines, and triglycerides and show that triglycerides may be due to a general inflammatory condition in the peritoneum. We also show that in addition to phosphatidylcholine alteration, there is also an effect in the ratio of phosphatidylcholine/phosphatidylethanolamine in serum of mice induced with the disease and that this change may be due to increased expression of the phosphatidylethanolamine N-methyltransferase gene. The study provides new insight into the etiology of endometriosis.
