Clinical Study

Abnormal Expression of Prostaglandins E2 and F2α Receptors and Transporters in Patients with Endometriosis

Table 2

Effect of endometriosis and menstrual cycle phase on expression of prostaglandin receptors and transporters in endometrium, based on real-time PCR and normalized relative to GAPDH mRNA as mean % ± SD. Also, = 30, 50, and 28, respectively, for healthy (control) subjects, eutopic tissue samples from endometriosis patients, and ectopic tissue samples.
