13. Polymorphism in CYP17, GSTM1 and the progesterone receptor genes and its relationship with mammographic density
Radiologic breast density is one of the predictive factors for breast cancer and the extent of the density is directly related to postmenopause. However, some patients have dense breasts even during postmenopause. This condition may be explained by the genes that codify for the proteins involved in the biosynthesis, as well as the activity and metabolism of

15. Expressão e reposição estrogenica e androgenica no lobo ventral da prostata de camundongos diabeticos (NOD) frente a terapia insulinica / Androgen and estrogen replacement and expression in the ventral lobe of the prostate of non-obese diabetic mice (NOD) following insulin therapy
Diabetes adversely affects prostate morphology and function through alterations in the hypothalamic-hypophyseal-gonadal axis. Thus, the aims of this study were to characterize morphological, proliferative and immunological features of the prostate of diabetic mice after long term glycemic control and hormonal replacement, and as well as to relate these param

16. Perfis das distroglicanas e morfo-fisiologia do lobo ventral da prostata de camundongos distroficos / Dystroglycans and laminin BETA 3 features on the prostate of mdx mice
The prostate is a fundamental accessory sex gland for the male reproductive process and the stroma-epithelium interaction has an important role in prostate structural maintenance and function. The basal membrane is an interaction link, offering mechanical and physiological support. Nowadays, different studies suggest that dystroglycan (DG), which is an adhes

17. Modulation of thyroid hormone receptor transactivation by the early region 1A (E1A)-like inhibitor of differentiation 1 (EID1)
Transcriptional activation (TA) mediated by the effect of thyroid hormones on target genes requires co-activator proteins such as the early region 1A (E1A) associated 300 kDa binding protein (p300) and the cAMP response element binding protein (CREB) binding protein (CBP), known as the p300/CBP complex, which acetylate histones 3 and 4 to allow transcription

18. Efeitos da administração prolongada do esteróide anabolizante decanoato de nandrolona em comportamentos emocionais e na expressão de genes relacionados ao sistema serotoninérgico em diferentes áreas cerebrais de camundongos / Effects of prolonged administration of the anabolic-androgenic steroid nandrolone decanoate in emotional behaviors and serotonergic system related genes expression in several brain areas of mice
Nandrolone decanoate is a highly abused anabolic-androgenic steroid (AAS) by individuals looking for gains in physical strength or body appearance. Supraphysiological doses of this testosterone synthetic derivative have been associated with many physical and psychiatric adverse effects, especially reported episodes of impulsiveness and overt aggressive behav

19. Indice de massa corporal, padrão de distribuição de gordura corporal e expressão de receptores hormonais em mulheres com carcinoma de mama invasivo
Objective: to evaluate the relation between body parameters used to define central obesity -waist circumference (WC) and waist to hip ratio (WRH)- and steroid receptor status in breast carcinomas of pre- and postmenopausal women. Subjects and methods: This is a cross-sectional study on 473 women with breast malignancies stage I-III, treated at the National C

20. Análise da expressão de RNAs não-codificadores intrônicos em tumores de mama / Gene expression analysis of intronic non-coding RNAs in breast tumors
O câncer de mama é o carcinoma que mais acomete mulheres no Brasil. Os tratamentos disponíveis são recomendados a partir da análise de fatores de prognóstico como a classificação pelo sistema TNM, tipo histológico, status de receptores hormonais e marcadores de proliferação tumoral. No entanto, a classificação dos tumores de mama é muito variá

21. Estudo do sistema neuroimunoendócrino na caquexia neoplásica e da resposta ao tratamento com esteróides
The anorexia-cachexia syndrome (ACS), of multifactorial source and complex, is common in chronic diseases, like advanced cancer. Is associated with weight loss and decrease food intake, sometimes causing death. The objective of the present study was to evaluate the influence of neoplastic cachexia over the hypothalamus-pituitary-adrenal axis and immune syste

22. REGULATION OF STEROID RECEPTORS AND FOLLICULAR DYNAMICS IN HORMONAL INDUCTION SYSTEM POSTPARTUM BEEF COWS / REGULAÇÃO DE RECEPTORES ESTERÓIDES E DINÂMICA FOLICULAR EM UM SISTEMA DE INDUÇÃO HORMONAL PÓSPARTO EM VACAS DE CORTE
The objective of the present study was to determine the action of gestagens and estradiol benzoate (EB) on the mechanism of premature regression of the first corpus luteum (CL) after parturition, and to develop an efficient artificial insemination system for suckling beef cows. The effect of pre-exposure to gestagens and EB on the expression of the alpha (ER

23. Role of ACTH receptor in adrenocortical tumor formation
Adrenocorticotrophin (ACTH) is the major regulatory hormone of steroid synthesis and secretion by adrenocortical cells. The actions of ACTH are mediated by its specific membrane receptor (ACTH-R). The human ACTH-R gene was recently cloned, allowing systematic determination of its sequence, expression and function in adrenal tumorigenesis. The presence of onc

24. The roles of sex steroid receptor coregulators in cancer
Sex steroid hormones, estrogen, progesterone and androgen, play pivotal roles in sex differentiation and development, and in reproductive functions and sexual behavior. Studies have shown that sex steroid hormones are the key regulators in the development and progression of endocrine-related cancers, especially the cancers of the reproductive tissues. The ac
