چکیده
OBJECTIVE To investigate the expression of vascular endothelial growth factor (VEGF) mRNA and thrombospondin-1 (TSP-1) mRNA in endometriosis. DESIGN Molecular studies in human tissue. SETTING Department of Obstetrics and Gynecology, Peking Union Medical College Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences, Beijing, P. R. China. PATIENT(S) Patients undergoing laparoscopy for infertility or other benign gynecologic conditions. INTERVENTION(S) Biopsies were taken from endometriotic lesions (red peritoneal lesion, ovarian endometrioma, and unterosacral ligament nudule) and eutopic endometrium during laparoscopy. MAIN OUTCOME MEASURE(S) mRNA expression from endometriotic lesion and eutopic endometrium was analyzed by reverse transcriptase polymerase chain reaction (PCR) and Northern blotting. RESULT(S) Among the endometriotic lesions, red peritoneal lesions expressed higher levels of VEGF mRNA and lower levels of TSP-1 mRNA, whereas ovarian endometrioma expressed lower levels of VEGF mRNA and higher levels of TSP-1 mRNA. Eutopic endometrium of women with endometriosis had higher expression levels of VEGF mRNA and lower expression levels of TSP-1 mRNA than that of women without endometriosis. CONCLUSION(S) The expression of VEGF and TSP-1 in endometriotic lesions appears to be associated with the extent of their neovascularization. The imbalance in expression of VEGF and TSP-1 in the endometrium may play a role in the development of endometriosis.

Background: Endometriosis is the presence of endometrium- like tissue in sites outside the uterine cavity, primarily on the pelvic peritoneum and ovaries. Ectopic endometrium for replacement and growth require to blood supply. Vascular endothelial growth factor (VEGF) is one of the most important intermediate of locality angiogenesis that product by monocytes and macrophages. This study evaluat...

Background: Endometriosis is a disease which is defined by the growth of endometrium-like tissue outside of the uterine cavity. Literatures show that VEGF by interaction with their receptors, Flt-1 (Fms-like tyrosine kinase-1 or VEGFR-1) and Flk-1/KDR (fetal liver kinase/ kinase-insert domain receptor or VEGFR-2) is related to pathogenesis of endometriosis. The purpose of this study was to eval...
