1. Canine POMC deletion (P187fs) allele frequency in Labrador Retrievers in Brazil
RESUMO: O Labrador Retriever é uma das principais raças caninas com maior predisposição à obesidade. Vários fatores, especialmente as interrelações entre a alimentação, exercício e fatores sociais, influenciam a probabilidade de um cão se tornar obeso. Além disso, fatores genéticos são também responsáveis pela obesidade em cães, e no Labrad

2. PROP1 overexpression in corticotrophinomas: evidence for the role of PROP1 in the maintenance of cells committed to corticotrophic differentiation
OBJECTIVE: The expression of transcription factors involved in early pituitary development, such as PROP1 and POU1F1, has been detected in pituitary adenoma tissues. In this study, we sought to characterize the transcriptional profiles of PROP1, POU1F1, and TBX19 in functioning and nonfunctioning pituitary adenomas in an attempt to identify their roles in t

3. Vias de sinalização e efeito biológico da corticotropina (ACTH), do peptídeo NH2-terminal da pró-opiomelanocortina (N-POMC) e do fator de crescimento de fibroblastos (FGF2) em culturas primárias de células da suprarrenal de rato. / Signaling pathways and biological effects of corticotropin (ACTH), pro-opiomelanocortin NH2-terminal peptide (N-POMC) and fibroblast growth factor type 2 (FGF2) in rat adrenal primary culture cells.
Um dos fatores que regula o córtex adrenal é o hormônio adrenocorticotrópico, ACTH, no entanto, o fator de crescimento de fibroblastos do tipo 2, FGF2, e os peptídeos N-terminais da pro-opiomelanocortina, N-POMC, também podem estar envolvidos. As vias de sinalização das proteínas quinases: ERK, JNK e p38, juntamente com outras vias como PKA, PKC e P

4. Association of hypotalamic POMC, NPY and IRS2 with feeding behavior in norma and overweight Wistar rats / Associação do PMOC, NPY e IRS2 hipotalâmicos com padrões de comportamento alimentar em ratos wistar normais e sobrepeso
The feeding behavior of a specie is determined by a group of phylogenetic, ontogenetic, and epigenetic features, and regulated by internal and external factors to the organism. The natural phenomena that govern life in our planet are mainly periodic, and the food stocks is not an exception. Each harvest is followed by a time between harvests, and this rhythm

5. Complete structure of the porcine pro-opiomelanocortin mRNA derived from the nucleotide sequence of cloned cDNA.
Polyadenylated RNA isolated from porcine pituitary neurointermediate lobes was used to construct a cDNA library. The library was screened with a rat genomic DNA fragment specific for pro-opiomelanocortin sequences. Two positive clones, pJA-19 and pJA-20, containing respectively 850 bp and 550 bp were characterized. Sequence analysis of the cDNA inserts revea

6. Intracellular misrouting and abnormal secretion of adrenocorticotropin and growth hormone in Cpefat mice associated with a carboxypeptidase E mutation
Cpefat mice carry a mutation in the carboxypeptidase E/H gene which encodes an exopeptidase that removes C-terminal basic residues from endoproteolytically cleaved hormone intermediates. These mice have endocrine disorders including obesity, infertility, and hyperproinsulinemia–diabetes syndrome, but the etiology remains an enigma. Because studies have ide

7. Structural organization of human genomic DNA encoding the pro-opiomelanocortin peptide.
We have isolated a human genomic DNA segment encoding the corticotropin-beta-lipotropin precursor peptide from a fetal DNA library, using previously cloned bovine cDNA for this peptide as a probe. The human genomic DNA was studied by electron microscope heteroduplex analysis and gel blotting methods, and its nucleotide sequence was determined and compared wi

8. CSF and plasma levels of pro-opiomelanocortin-related peptides in reversible ischaemic attacks and strokes.
Plasma and CSF beta-endorphin (beta-EP), beta-lipotropin (beta-LPH) and ACTH levels were studied in a group of 25 patients who underwent reversible ischaemic attacks or completed strokes. CSF beta-EP and beta-LPH in ischaemic patients were higher than those of the control population, independently of both clinical reversibility of the cerebral damage, and th

10. Partial characterization of the mRNA that codes for enkephalins in bovine adrenal medulla and human pheochromocytoma.
[Met]enkephalin and [Leu]enkephalin are derived from a protein in bovine adrenal medulla that contains multiple copies of [Met]enkephalin [Kilpatrick, D. L., Taniguchi, T., Jones, B. N., Stern, A. S., Shively, J. E., Hullihan, J., Kimura, S., Stein, S. & Udenfriend, S. (1981) Proc. Natl. Acad. Sci. USA 78, 3265--3268.] Here we characterize pro-enkephalin mRN

11. Tissue-specific activity of the pro-opiomelanocortin gene promoter.
The pro-opiomelanocortin (POMC) gene is specifically expressed in corticotroph cells of the anterior pituitary. To define the POMC promoter sequences responsible for tissue-specific expression, we assessed POMC promoter activity by gene transfer into POMC-expressing pituitary tumor cells (AtT-20) and fibroblast L cells. The rat POMC promoter was only efficie

12. Hormonally mediated negative regulation of human pro-opiomelanocortin gene expression after transfection into mouse L cells.
We report results indicating that expression and hormonally controlled negative regulation of the human pro-opiomelanocortin (POMC) gene in mouse fibroblasts can be accomplished by the placement nearby of a simian virus 40 enhancer sequence. Expression resulting from correctly initiated transcription required the enhancer in cis both in cells stably transfec
