Biomarker: PR

Histology type: endometrial carcinoma

Country: Netherlands

Region: Nijmegen

Followed up time :

Conclusion: In conclusion to improve correct preoperative diagnosis in EC, we recommend use of a panel of at least two easily accessible immunohistochemical biomarkers (PR and p53), only in grade 2 ECs.

Sample type : tissue

Sample method: immunohistochemistry

Expression pattern : PR+p53

Expression elevation: The staining index (0-9) was obtained by the product of intensity, graded from 0 (no staining), 1 (weak staining), 2 (moderate staining) to 3 (strong staining), and area of tumor with this staining intensity, graded from 0 (no positive tumor cells), 1 (1-10% positive tumor cells), 2 (11-50% positive tumor cells) to 3 (>50% positive tumor cells).

Funtion Uniprot: The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Depending on the isoform, progesterone receptor functions as transcriptional activator or repressor.3 PublicationsCurated Isoform A Ligand-dependent transdominant repressor of steroid hormone receptor transcriptional activity including repression of its isoform B, MR and ER. Transrepressional activity may involve recruitment of corepressor NCOR2.3 Publications2 Publications Isoform B Transcriptional activator of several progesteron-dependent promoters in a variety of cell types. Involved in activation of SRC-dependent MAPK signaling on hormone stimulation.1 Publication Isoform 4 Increases mitochondrial membrane potential and cellular respiration upon stimulation by progesterone.

Molecular function from UniProt:

Tissue specificity from UniProt: In reproductive tissues the expression of isoform A and isoform B varies as a consequence of developmental and hormonal status. Isoform A and isoform B are expressed in comparable levels in uterine glandular epithelium during the proliferative phase of the menstrual cycle. Expression of isoform B but not of isoform A persists in the glands during mid-secretory phase. In the stroma, isoform A is the predominant form throughout the cycle. Heterogeneous isoform expression between the glands of the endometrium basalis and functionalis is implying region-specific responses to hormonal stimuli
