Composition and histone substrates of polycomb repressive group complexes change during cellular differentiation

Kuzmichev, A.; Margueron, R.; Vaquero, A.; Preissner, T. S.; Scher, M.; Kirmizis, Antonis; Ouyang, X.; Brockdorff, N.; Abate-Shen, C.; Farnham, P.; Reinberg, D. (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 ...

Differential expression of the rat retinoid X receptor γ gene during skeletal muscle differentiation suggests a role in myogenesis

Georgiades, Pantelis; Brickell, P. M. (1997)

Even though previous studies have shown that transcripts encoding the murine retinoid X receptor γ (RXRγ) are present in skeletal muscle of mouse embryos and that cultured myoblasts are induced to differentiate upon retinoid ...

Evidence for activation of the unfolded protein response in collagen iv nephropathies

Pieri, Myrtani; Stefanou, Charalambos; Zaravinos, Apostolos; Erguler, K.; Stylianou, Konstantinos G.; Lapathitis, Georgios; Karaiskos, Christos; Savva, Isavella; Paraskeva, Revekka; Dweep, H.; Sticht, C.; Anastasiadou, Natassa; Zouvani, Ioanna; Goumenos, Dimitrios S.; Felekkis, Kyriacos N.; Saleem, M.; Voskarides, Konstantinos; Gretz, N.; Constantinou-Deltas, Constantinos D. (2014)

Thin-basement-membrane nephropathy (TBMN) and Alport syndrome (AS) are progressive collagen IV nephropathies caused by mutations in COL4A3/A4/A5 genes. These nephropathies invariably present with microscopic hematuria and ...

Genomic approaches that aid in the identification of transcription factor target genes

Kirmizis, Antonis; Farnham, P. J. (2004)

It is well-established that deregulation of the transcriptional activity of many different genes has been causatively linked to human diseases. In cancer, altered patterns of gene expression are often the result of the ...

Groucho mediates a Ci-independent mechanism of hedgehog repression in the anterior wing pouch

Apidianakis, Yiorgos; Grbavec, D.; Stifani, S.; Delidakis, Christos (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 ...

The homeobox transcription factor cut coordinates patterning and growth during drosophila airway remodeling

Pitsouli, Chrysoula; Perrimon, N. (2013)

A fundamental question in developmental biology is how tissue growth and patterning are coordinately regulated to generate complex organs with characteristic shapes and sizes. We showed that in the developing primordium ...

The identification and characterization of KRAB-domain-containing zinc finger proteins

Constantinou-Deltas, Constantinos D.; Gilbert, J.; Bartlett, R. J.; Herbstreith, M.; Roses, A. D.; Lee, J. E. (1992)

The zinc finger motif is a highly conserved tandemly repeated sequence of 28-30 amino acids that was first identified in transcription factor TFIIIA from Xenopus laevis. Subsequently, similar motifs were found and characterized ...

Overexpression of the m4 and mα genes of the E(spl)-Complex antagonizes Notch mediated lateral inhibition

Apidianakis, Yiorgos; Nagel, A. C.; Chalkiadaki, Angeliki; Preiss, A.; Delidakis, Christos (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

De La Cruz, C. C.; Kirmizis, Antonis; Simon, M. D.; Isono, K. -I; Koseki, H.; Panning, B. (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 ...

Regulation of retinoid X receptor-γ gene transcript levels in rat heart cells

Georgiades, Pantelis; Brickell, P. M. (1998)

Retinoid X receptor-γ (RXRγ) is a transcription factor that mediates retinoid signalling and is expressed in rat heart during adult life. However, its expression in embryonic and neonatal heart has not been investigated ...

Article

Retinoid X receptor-γ gene expression is developmentally regulated in the embryonic rodent peripheral nervous system

Georgiades, Pantelis; Wood, J.; Brickell, P. M. (1998)

The retinoid X receptor-γ (RXRγ) is a transcription factor that belongs to the thyroid hormone/retinoid family of nuclear receptors. Previous studies have shown that RXRγ is expressed in the developing peripheral nervous ...

Silencing of human polycomb target genes is associated with methylation of histone H3 Lys 27

Kirmizis, Antonis; Bartley, S. M.; Kuzmichev, A.; Margueron, R.; Reinberg, D.; Green, R.; Farnham, P. J. (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 ...

Targeting IL13Ralpha2 activates STAT6-TP63 pathway to suppress breast cancer lung metastasis

Papageorgis, P.; Ozturk, S.; Lambert, A. W.; Neophytou, Christiana M.; Tzatsos, Alexandros; Wong, C. K.; Thiagalingam, S.; Constantinou, Andreas I. (2015)

Introduction: Basal-like breast cancer (BLBC) is an aggressive subtype often characterized by distant metastasis, poor patient prognosis, and limited treatment options. Therefore, the discovery of alternative targets to ...
