Activation of eukaryotic genes often relies on remote chromatin determinants. How these determinants function remains poorly understood. The hGH gene is activated by a 5'-remote locus control region (LCR). Pituitary-specific DNase I hypersensitive site I (HSI), the dominant hGH LCR element, is separated from the hGH-N promoter by a 14.5 kb span that(More)
Gene activation in higher eukaryotes is often under the control of regulatory elements quite distant from their target promoters. It is unclear how such long-range control is mediated. Here we show that a single determinant of the human growth hormone locus control region (hGH LCR) located 14.5 kb 5prime prime or minute to the hGH-N promoter has a critical,(More)
The cluster of genes encoding the human growth hormone (GH) contains an array of five highly related genes. From 5' to 3' these are: GHN, CSL (encoding chorionic somatomammotropin-like gene), CSA, GHV (encoding GH-variant gene) and CSB. These five genes are expressed in mutually exclusive tissue distributions, GHN in pituitary somatotropes and the remaining(More)
Notch is needed for T-cell development and is a common oncogenic driver in T-cell acute lymphoblastic leukemia. The protooncogene c-Myc (Myc) is a critical target of Notch in normal and malignant pre-T cells, but how Notch regulates Myc is unknown. Here, we identify a distal enhancer located >1 Mb 3' of human and murine Myc that binds Notch transcription(More)
