This study investigated the possible use of CCR1 mRNA measurement in peripheral blood leukocytes in combination with measurements of monocyte chemotactic protein-1 (MCP-1) and CA125 protein in serum as a diagnostic test for endometriosis.The expression of CCR1 mRNA in peripheral blood leukocytes was measured by quantitative real-time polymerase chain reaction. MCP-1 and CA125 levels in serum were determined by ELISA and ECLIA.The ratio of CCR1/HPRT mRNA in peripheral blood of patients with endometriosis and adenomyosis was significantly elevated compared with women without endometriosis. Additionally, serum levels of MCP-1 and CA125 were significantly higher in patients with endometriosis. This method showed a sensitivity of 92.2%, a specificity of 81.6%, a negative predictive value of 83.3%, a positive predictive value of 92.3%, a likelihood ratio of a positive test result of 5.017, and a likelihood ratio of a negative test result of 0.096 to predict the presence or absence of endometriosis.The results imply the potential use of CCR1 mRNA, MCP-1, and CA125 protein measurements for the diagnosis or exclusion of endometriosis.

We have demonstrated that sulindac exerts strong antiinflammatory effects by suppression of NF-kappaB translocation, inhibition of NF-kappaB-mediated gene transcription, RANTES gene expression, and protein secretion in normal and endometriotic stromal cells. These results suggest that drugs targeting the NF-kappaB pathway may be beneficial in the treatment of endometriosis-associated symptoms.

Apoptosis is a physiologic process that eradicates undesired cells without inducing an inflammatory reaction. It is an important regulator of eutopic endometrial function and evidence suggests that apoptosis aids in maintaining cellular homeostasis during the menstrual cycle by eliminating aging cells from the functional layer of the uterine endometrium. Endometriosis, which is characterized by the growth of endometrial tissue outside the uterus, could result from increased cellular proliferation or decreased apoptosis in response to appropriate stimuli. Eutopic endometrium from women with endometriosis has several differences compared with normal endometrium of women without endometriosis. These differences may contribute to the survival of regurgitated endometrial cells into the peritoneal cavity and thus to the development of endometriosis. In this article, we will summarize recent literature concerning apoptosis-related genes such as Bcl-2 and Fas, outline the molecular basis of apoptosis and review the literature focused on the alterations in regulation of apoptosis in eutopic and ectopic endometrium from women with endometriosis.

Peroxisome proliferator-activated receptors (PPAR) are members of the nuclear hormone receptor superfamily. Synthetic ligands to one family member, PPARgamma, are currently widely used as treatment for chronic diseases such as diabetes type II and other insulin resistances, e.g. as seen in polycystic ovary syndrome (PCOS). Moreover, novel approaches employing knock-out mice demonstrated that PPARgamma seems to play a key role in placental and fetal development. This review describes recent insights into the role of PPARs in human reproduction with specific reference to infertility, placental maturation and fetal development as well as disturbed pregnancy. Further, we highlight the current knowledge on synthetic ligands to PPARgamma used as a treatment in women with PCOS.
