Abundant immunohistochemical expression of dopamine D2 receptor and p53 protein in meningiomas: follow-up, relation to gender, age, tumor grade, and recurrence
Autor: G. Trott, J.F.S. Pereira-Lima, C.G.S. Leães, N.P. Ferreira, L.M. Barbosa-Coutinho, M.C. Oliveira
Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 48, Iss 5, Pp 415-419 (2015)
Meningiomas are common, usually benign tumors, with a high postoperative recurrence rate. However, the genesis and development of these tumors remain controversial. We aimed to investigate the presence and implications of a mutated p53 protein and do

Male gonadal function, prolactin secretion and lactotroph population in an experimental model of cirrhosis
Autor: P.H. Gonzales, C.R. Rhoden, C. Luz, G. Corrêa, L.M. Barbosa-Coutinho, M.C. Oliveira
Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 40, Iss 10, Pp 1383-1388 (2007)
Liver cirrhosis, a highly prevalent chronic disease, is frequently associated with endocrine dysfunctions, notably in the gonadal axis. We evaluated lactotroph population by immunohistochemistry, gonadotropins and prolactin by immunoradiometric assay

Aversive stimulation during the stress-hyporesponsive period does not affect the number of corticotroph cells in neonatal male rats
Autor: C.E. Aguiar, L.P. Cadore, M.J. Padoin, L.M. Barbosa-Coutinho, A.B. Lucion
Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 30, Iss 12, p 1463 (1997)
Immunohistochemistry was used to evaluate the effects of neonatal handling and aversive stimulation during the first 10 days of life on the number of corticotrophs in the anterior lobe of the pituitary of 11-day-old male Wistar rats. Since adult rats

Effects of bromocriptine on serum prolactin levels, pituitary weight and immunoreactive prolactin cells in estradiol-treated ovariectomized rats: an experimental model of estrogen-dependent hyperprolactinemia
Autor: M.F. Ribeiro, P.M. Spritzer, L.M. Barbosa-Coutinho, M.C. Oliveira, M.A. Pavanato, I.S.B. Silva, F.M. Reis
Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 30, Iss 1, p 113 (1997)
The present study was designed to assess the effects of bromocriptine, a dopamine agonist, on pituitary wet weight, number of immunoreactive prolactin cells and serum prolactin concentrations in estradiol-treated rats. Ovariectomized Wistar rats were

Publikováno v: Neuropathology. 29:40-44
Angiogenesis, a fundamental process for the development and growth of a tumor, is less expressive in adenomas than in the normal pituitary tissue. There is controversy about the behavior of angiogenesis as a function of hormonal secretion or other ch

Expression of p53 protein in pituitary adenomas
Autor: L.M. Barbosa-Coutinho, Júlia Fernanda Semmelmann Pereira-Lima, Cristina B. Pizarro, Miriam da Costa Oliveira, Caroline P. Marroni, Nelson Pires Ferreira
Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 35, Iss 5, Pp 561-565 (2002)
Brazilian Journal of Medical and Biological Research, Volume: 35, Issue: 5, Pages: 561-565, Published: MAY 2002
Inactivating mutations of TP53, a tumor suppressor gene, are associated with abnormal cell proliferation. Although p53 expression is common in many human malignancies, p53 protein has seldom been evaluated in pituitary tumors. When detected, the perc

Publikováno v: Endocrine pathology. 21(1)
Pituitary adenomas (PA) occasionally show aggressive behavior, with invasion of the surrounding tissues. The identification of markers able to recognize aggressive PA in early stages remains a challenge. We aimed to determine the expression of a new
