Quantitative real-time PCR analysis of mRNA expression in chorionic villi and the implantation site in fallopian tube of tubal pregnancy. There were no significant differences between the two groups in the mRNA expressions of estrogen receptor (ER)-alpha, progestogen receptor (PR), leukemia inhibitory factor (LIF), vascular endothelial growth factor (VEGF), inducible nitric oxide synthase (iNOS), and endocannabinoid receptor 1 (CB1) in chorionic villi and the implantation site in fallopian tube of tubal pregnancy. All mRNA expression values were normalized against the glyceraldehyde-3-phosphate dehydrogenase (GAPDH) endogenous control gene.
