Identification and analysis of prophet of Pit-1-binding sites in human Pit-1 gene.
Prophet of Pit-1 (Prop1) is a transcription factor that regulates Pit-1 gene expression. Because Pit-1 regulates the differentiation of pituitary cells and the expressions of GH, prolactin and TSHbeta genes, Prop1 mutation results in combined pituitary hormone deficiency in humans. However, Prop1-binding sites in human Pit-1 gene and the mechanism leading to combined pituitary hormone deficienc...
متن کاملCharacterization of Prophet of Pit-1 gene expression in normal pituitary and pituitary adenomas in humans.
Prophet of Pit-1 (Prop-1), which is a paired-like homeodomain transcription factor, is capable of binding to sites in an early enhancer of the Pit-1 gene and regulating its expression. According to a previous report, Prop-1 messenger RNA (mRNA) is expressed in the developing pituitary gland before Pit-1 mRNA expression and maximum expression are observed at e 12.0. After e 14.5, Prop-1 mRNA exp...

15 صفحه اولA single base difference between Pit-1 binding sites at the hGH promoter and locus control region specifies distinct Pit-1 conformations and functions.
Activation of the human growth hormone (hGH-N) gene in pituitary somatotropes is mediated by a locus control region (LCR). This LCR is composed of DNase I-hypersensitive sites (HS) located -14.5 kb to -32 kb relative to the hGH-N promoter. HSI, at -14.5 kb, is the dominant determinant of hGH-N expression and is essential for establishment of a 32-kb domain of histone acetylation that encompasse...

The Des Moines Lobe was the largest of several lobes of the Laurentide Ice Sheet that extended into the mid-continent region of North America near the end of the last glaciation. At its maximum extent, ~13,800 radiocarbon years ago, the lobe was up to 250 km wide and covered greater than 10 km in southern Minnesota and north-central Iowa (Fig. 1). The lobe deposited diverse sediments, but only ...
