13. Expressão e valor prognóstico dos receptores de estrógeno e progesterona em tumores borderline e carcinomas de ovário / Expression and prognostic value of estrogen and progesterone receptors status in borderline ovarian tumors and ovarian carcinomas
Introdução: Evidências recentes sugerem que a estimulação hormonal dos esteróides pode estar envolvida no desenvolvimento e prognóstico das neoplasias de ovário. O estrogênio é um importante regulador do crescimento e diferenciação das células ovarianas, enquanto a progesterona pode oferecer proteção contra os efeitos mutagênicos do estrógen

14. Controle hormonal da próstata feminina do gerbilo sob influência de múltiplas prenhezes e reposição hormonal / Hormonal control of the gerbil s female prostate : influence of multiple pregnancies and hormone replacement
The gerbil female prostate is located paraurethrally and has all the main histological components of the male prostate, like secretor epithelium and fibromuscular stroma. This gland, like the prostate in males, is targeted by testosterone action, which promotes morphofunctional development. Furthermore, estrogens are required to maintain the male and female

15. Transcriptional regulation of bidirectional gene pairs by 17-β-estradiol in MCF-7 breast cancer cells
Using cDNA microarray analysis, we previously identified a set of differentially expressed genes in primary breast tumors based on the status of estrogen and progesterone receptors. In the present study, we performed an integrated computer-assisted and manual search of potential estrogen response element (ERE) binding sites in the promoter region of these ge

16. Expression of e-cadherin, n-cadherin and snail and their correlation with clinicopathological variants: an immunohistochemical study of 132 invasive ductal breast carcinomas in Egypt
OBJECTIVE: To evaluate the expression of the cell adhesion molecules E-cadherin and N-cadherin and the transcription factor Snail in invasive ductal breast carcinomas and to determine their relationships with clinicopathological features. METHODS: Immunohistochemistry was used to examine E-cadherin, N-cadherin, and Snail protein expression in 132 invasive br

17. Expression of Hypoxia-inducible factor 1-α and Vascular endothelial growth factor-C in locally advanced breast cancer patients
BACKGROUND: Locally advanced breast cancers are more prevalent in underdeveloped countries. Targeted therapy has been improved to identify hallmarks that are specific to these subtypes of tumors. OBJECTIVES: We aimed to prospectively assess the expression of Hypoxia inducible factor-1 α and vascular endothelial growth factor-C in locally advanced breast can

18. Cloning, mapping and molecular characterization of porcine progesterone receptor membrane component 2 (PGRMC2) gene
Progesterone plays an important role in sow reproduction by stimulating classic genomic pathways via nuclear receptors and non-genomic pathways via membrane receptors such a progesterone receptor membrane component 2 (PGRMC2). In this work, we used radiation hybrid mapping to assign PGRMC2 to pig chromosome 8 and observed that this receptor has two transcrip

19. Comparação dos resultados de marcadores prognósticos e preditivos (HER2 e receptores de estrógeno e progesterona) para carcinoma de mama entre laboratórios locais e de referência no Brasil / Comparison of results of prognostic and predictive markers (HER2 and estrogen and progesterone receptors) for breast carcinoma between local and reference laboratories in Brazil
Breast cancer accounts for approximately one quarter of all cancers in females. The incidence of breast cancer in Brazil is about 50,000 new cases per year, and it is considered an important public health problem. HER2 and hormone receptors (estrogen and progesterone receptors) are considered the main prognostic and predictive markers for breast carcinoma. H

20. The progins progesterone receptor gene polymorphism is not related to endometriosis-associated infertility or to idiopathic infertility
OBJECTIVE: This study aimed to determine the frequency of the PROGINS polymorphism in women with endometriosis-associated infertility, in infertile women without endometriosis and in controls. INTRODUCTION: The human progesterone receptor gene has two isoforms that modulate the biological action of progesterone: isoform A, which is capable of inhibiting the

21. Cycle modulation of insulin-like growth factor-binding protein 1 in human endometrium
Endometrium is one of the fastest growing human tissues. Sex hormones, estrogen and progesterone, in interaction with several growth factors, control its growth and differentiation. Insulin-like growth factor 1 (IGF-1) interacts with cell surface receptors and also with specific soluble binding proteins. IGF-binding proteins (IGF-BP) have been shown to modul

22. Immunohistochemical study of androgen, estrogen and progesterone receptors in salivary gland tumors
The aim of this work was to study the immunohistochemical expression of androgen receptor, estrogen receptor and progesterone receptor in pleomorphic adenomas, Warthin's tumors, mucoepidermoid carcinomas and adenoid cystic carcinomas of salivary glands. A total of 41 pleomorphic adenomas, 30 Warthin's tumors, 30 mucoepidermoid carcinomas and 30 adenoid cysti

23. xpression of estrogen and progesterone receptor genes in endometrium, myometrium and vagina of postmenopausal women treated with estriol
CONTEXT AND OBJECTIVE: Estriol is an estrogen with considerably weaker stimulatory effects on endometrial proliferation than estradiol. A study was conducted to determine the level of estrogen receptors (ERs) and progesterone receptors (PRs) in women who received 14-day vaginal estriol therapy, compared with those who did not receive this therapy. ER and PR

24. Avaliação da influencia dos hormonios sexuais na nocicepção da articulação temporomandibular de ratos e estudo dos mecanismos envolvidos / The role of sex hormones in temporomandibular joint nociception and study of the mechanisms involved
The aim of this study was to evaluate the effect of sex hormones on temporomandibular joint (TMJ) nociception in rats and the possible mechanisms underlying their effect. The TMJ injection of 0.5% formalin induced nociception in intact females and gonadectomized males, but not in intact males, suggesting that the physiological level of testosterone protect m
