Complete coding sequence, exon/intron arrangement and chromosome location of ZNF45, a KRAB-domain-containing gene
(1996)Zinc finger genes represent a large multigene family present in mammalian and other genomes. A subgroup of these genes contain a conserved motif, the KRAB domain, at the NH2-terminal region, which was recently shown to ...

Article
Composition and histone substrates of polycomb repressive group complexes change during cellular differentiation
(2005)Changes in the substrate specificities of factors that irreversibly modify the histone components of chromatin are expected to have a profound effect on gene expression through epigenetics. Ezh2 is a histone-lysine ...

Groucho mediates a Ci-independent mechanism of hedgehog repression in the anterior wing pouch
(2001)Groucho (Gro) is the founding member of a family of transcriptional co-repressors that are recruited by a number of different transcription factors. Drosophila has a single gro gene, whose loss of function affects processes ...

Article
Hedgehog restricts its expression domain in the Drosophila wing
(2007)The stable subdivision of Drosophila limbs into anterior and posterior compartments is a consequence of asymmetrical signalling by Hedgehog (Hh), from the posterior to anterior cells. The activity of the homeodomain protein ...

Article
The HPV16 oncogenes cause aberrant stem cell mobilization
(2013)Human Papilloma Virus related epithelial cancers have been speculated to derive from virus-infected tissue stem cells. Stem cells also are thought to provide a reservoir of latently infected cells that can persist for long ...

Article
Human papillomavirus type 16 E6 and E7 oncoproteins act synergistically to cause head and neck cancer in mice
(2010)High-risk human papillomaviruses (HPVs) contribute to cervical and other anogenital cancers, and they are also linked etiologically to a subset of head and neck squamous cell carcinomas (HNSCC). We previously established ...

Identification of biomarkers that distinguish human papillomavirus (HPV)-positive versus HPV-negative head and neck cancers in a mouse model
(2006)Head and neck squamous cell carcinoma (HNSCC) is a leading cause of cancer mortality worldwide. Recent reports have associated a subset of HNSCC with high-risk human papillomaviruses (HPVs), particularly HPV16, the same ...

Article
Identification of the polycomb group protein SU(Z)12 as a potential molecular target for human cancer therapy
(2003)We have previously identified SU(Z)12 as an E2F target gene. Because many E2F target genes encode proteins that are critical for the control of cell proliferation, we have further characterized the regulation and expression ...

Article
Overexpression of the m4 and mα genes of the E(spl)-Complex antagonizes Notch mediated lateral inhibition
(1999)Intercellular signalling mediated by Notch proteins is crucial to many cell fate decisions in metazoans. Its profound effects on cell fate and proliferation require that a complex set of responses involving positive and ...

The Polycomb Group Protein SUZ12 regulates histone H3 lysine 9 methylation and HP1α distribution
(2007)Regulation of histone methylation is critical for proper gene expression and chromosome function. Suppressor of Zeste 12 (SUZ12) is a requisite member of the EED/EZH2 histone methyltransferase complexes, and is required ...

Article
Silencing of human polycomb target genes is associated with methylation of histone H3 Lys 27
(2004)Polycomb group (PcG) complexes 2 and 3 are involved in transcriptional silencing. These complexes contain a histone lysine methyltransferase (HKMT) activity that targets different lysine residues on histones H1 or H3 in ...
