The role of estrogen (ER) and progesterone receptors (PR) in breast cancer is well
established. Identification of the second human estrogen receptor, the estrogen receptor β …

To elucidate the clinical importance of estrogen receptor (ER) β in breast cancer, 29 archival
primary breast cancer specimens, six locally recurrent cancers, and five benign mammary …

The assessment of the estrogen receptor (ER) α and the progesterone receptor (PgR) in
breast cancer tissues is important for discriminating between hormone-dependent and …

The recent discovery of a second estrogen receptor (ER), designated ERβ, raises pressing
questions about its role in estrogen regulation of human breast cancer cells and its …

Aims: The majority of all breast cancers are hormone responsive, traditionally defined by the
expression of oestrogen receptor (ER) α and/or progesterone receptors. In contrast to ERα …

To estimate the clinical value of estrogen receptor (ER) β expression in breast cancer we
used an immunohistochemical method to detect the wild-type ERβ in 88 primary breast …

The cloning of a second estrogen receptor (ER), ERβ, has prompted a reevaluation of the
role of ERs in breast cancer. The aim of this study was to determine the expression of both …

Using messenger RNA (mRNA) in situ hybridization, we investigated estrogen receptor-β
(ERβ) mRNA levels in normal mammary, benign breast tumor (BBT), breast cancer (BC) …

Purpose: Previous conflicting results about the prognostic significance of estrogen receptor
(ER)-β in breast cancer may be explained by contribution of isoforms, of which five exist. Our …

To understand the significance of estrogen receptor β (ERβ) in mammary carcinogenesis,
we evaluated the expression of ERβ in preinvasive mammary tumors. The percentage of …
