Biomarker: estrogen receptor

Histology type: endometrial carcinoma

Stage: risk

Country: European Network for Individualized Treatment of Endometrial Cancer (ENITEC) centers

Study type: retrospective multicenter study

Followed up time :

Conclusion: We propose classification of ER and PR expression based on a high-risk (0-10%), intermediate-risk (20-80%), and low-risk (90-100%) group.

Sample type : tissue

Sample method: immunohistochemistry

Expression pattern : ER/PR expression

Expression elevation: Scoring of ER and PR staining in percentages was determined by eyeballing in a semiquantitative manner.The percentage of tumor cells exhibiting positive nuclear expression was subsequently categorized into the following categories: ≤1%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%.Discrepancies in scoring were reviewed in a consensus meeting attended by all assessors.

Funtion Uniprot: Binds to an ERR-alpha response element (ERRE) containing a single consensus half-site, 5'-TNAAGGTCA-3'. Can bind to the medium-chain acyl coenzyme A dehydrogenase (MCAD) response element NRRE-1 and may act as an important regulator of MCAD promoter. Binds to the C1 region of the lactoferrin gene promoter. Requires dimerization and the coactivator, PGC-1A, for full activity. The ERRalpha/PGC1alpha complex is a regulator of energy metabolism. Induces the expression of PERM1 in the skeletal muscle.
