levels in EF. In contrast to our results, a significant negative correlation was observed between OBR transcripts and PF leptin levels in ectopic endometrium. These significant positive correla tions suggest that OBR may be induced in OE and PI by leptin levels in EF and PF, respectively. Given the presence of large quantities of leptin in the OE, it remains unknown whether this inflammatory fac tor contributes to both the decreased oocyte reserve and the quality of the affected ovary. A prospective study re vealed that elevated intra ovarian leptin concentrations were associated with reduced ovarian stimulation and response, reduced follicle maturation, poorer embryo quality and a lower likelihood of successful pregnancy, suggesting that leptin modulates embryo quality and may serve as a sensitive marker of IVF outcomes.

We thus suggest that the increased leptin levels in the ovarian EF may play an important role in the reproduct ive abnormalities that accompany this disease, but fur ther studies are required to support this hypothesis. Disorders related to leptin deficit and leptin overabun dance required the development of drugs (-)-p-Bromotetramisole Oxalate cost that activate or in hibit the OBR. The administration of the pegylated leptin peptide receptor antagonist or nonfunctional OBR in a rat model of endometriosis demon strated that disruption of leptin signaling can inhibits the establishment and development of endometriosis like lesions that resemble peritoneal endometriotic foci.

A leptin mu tant with antagonistic properties and other proteins that block leptin activity open up new possibilities for research and, eventually, therapy selleck BAPTA-AM for OE and similar diseases, which do not respond well to any available medication. Conclusion In summary, this study shows that the expression of OBR is higher in the ovarian tissue affected by OE in infertile pa tients than in the normal ovarian tissue of fertile controls not affected by endometriosis. There was a positive and sig nificant correlation between leptin and OBR expression in the OE and PI. We also demonstrated the presence of high levels of leptin in the chocolate fluid in the OE, wich correlated strongly and positively with the expression of leptin and OBR in the OE, while leptin levels in PF corre lated with the expression of leptin and OBR in PI. These data suggest that leptin may have an important role in the physiopathology of OE through a modulatory interaction with its active receptor.

Background Ovarian cancer is still the most lethal of all gynecologic cancers. The American Cancer Society estimated that about 22,240 new cases of ovarian cancer will be diag nosed and 14,030 women will die of ovarian cancer in the United States in 2013. There are various methods for treating of recurrent ovarian cancer and chemothera peuti
