Using reverse transcription-polymerase chain reaction (RT-PCR), we studied the expression of oestrogen receptor-alpha splicing variants and oestrogen receptor-beta in uterine biopsies from 12 patients with endometriosis and 15 patients with unexplained infertility.
Polymorphisms in the estrogen receptor beta gene but not estrogen receptor alpha gene affect the risk of developing endometriosis in a Japanese population.

Because endometriosis is now thought to be, at least in part, an inflammatory disease, we evaluated ERB-041's activity in an experimentally induced model of endometriosis.
Taken together, methylation of a CpG island at the ESR2 promoter region is a primary mechanism responsible for differential expression of ESR2 in endometriosis and endometrium.

To investigate whether a polymorphism in the ESR2 gene (rs4986938, previously associated with endometriosis, ovulatory dysfunction and premature onset of coronary heart disease) increases the risk of Graves' disease (GD).
Genetic variants in ESR1, ESR2, and HSD17B1 genes could modify susceptibility to endometriosis and might influence the fertility status in endometriosis patients.
We evaluated the relationship between common genetic variation and endometriosis risk, using gene-based tests and single-variant analysis of genetic polymorphisms in ESR1, ESR2, PGR, CYP17A1, CYP19A1, HSD17B1, HSD17B2, CYP1A1, CYP1A2, COMT, and GSTM1.
Granulosa cells obtained from patients with endometriosis were examined for estrogen (ER-β, ER-α) and progesterone (PR-A, PR-B) receptor mRNA expression ratio against GAPDH.
In this study, we have examined the expression of the four main ERβ transcript isoforms in human endometrial tissue in women with or without endometriosis.
Because estrogen receptor (ER)β levels in endometriosis are >100 times higher than those in endometrial tissue, this review focuses on this nuclear receptor.
No association was found with ESR1 (rs1159327 A/G, rs3020348 A/C) and ESR2 (rs17179740 A/G) either for endometriosis or endometriosis-related infertility.
Our results revealed that the positive ratio of ER-β expression was gradually reduced during the malignant transformation from endometriosis to atypical endometriosis to clear cell carcinoma.
