AURKB-mediated effects on chromatin regulate binding versus release of XIST RNA to the inactive chromosomeLisa L Hall
Department of Cell Biology, University of Massachusetts Medical School, Worcester, MA 01655, USA
J Cell Biol 186:491-507. 2009..Results suggest a model of multiple distinct anchor points for XIST RNA. This study advances understanding of RNA chromosome binding and the roles of AURKB and demonstrates a novel approach to manipulate and study XIST RNA...
X-inactivation reveals epigenetic anomalies in most hESC but identifies sublines that initiate as expectedLisa L Hall
Department of Cell Biology, U Mass Med School, Worcester, Massachusetts 01655, USA
J Cell Physiol 216:445-52. 2008..The many epigenetic anomalies seen indicate that maintenance of fully unspecialized cells, which have not formed Xi facultative heterochromatin, is a delicate epigenetic balance difficult to maintain in culture...
The cell biology of a novel chromosomal RNA: chromosome painting by XIST/Xist RNA initiates a remodeling cascadeLisa L Hall
Department of Cell Biology, University of Massachusetts Medical School, 55 Lake Avenue North, Worcester, MA 01655, USA
Semin Cell Dev Biol 14:369-78. 2003....
An ectopic human XIST gene can induce chromosome inactivation in postdifferentiation human HT-1080 cellsLisa L Hall
Department of Cell Biology, University of Massachusetts Medical School, Worcester, MA 01655, USA
Proc Natl Acad Sci U S A 99:8677-82. 2002..These results have fundamental significance for understanding genomic programming in early development...
BRCA1 does not paint the inactive X to localize XIST RNA but may contribute to broad changes in cancer that impact XIST and Xi heterochromatinGayle J Pageau
Department of Cell Biology, University of Massachusetts Medical School, Worcester, MA 01655, USA
J Cell Biochem 100:835-50. 2007..We provide preliminary evidence that this may occur as part of a wider failure of heterochromatin maintenance in some cancers...
Molecular anatomy of a speckleLisa L Hall
Department of Cell Biology, University of Massachusetts Medical School, Worcester, 01655, USA
Anat Rec A Discov Mol Cell Evol Biol 288:664-75. 2006..Conditions that disperse SC35 also disperse poly(A) RNA, whereas the splicing factor ASF/SF2 can be dispersed under conditions in which SC35 or SRm300 remain as intact components of a core domain...
Maternal Rnf12/RLIM is required for imprinted X-chromosome inactivation in miceJongdae Shin
Program in Gene Function and Expression, University of Massachusetts Medical School UMMS, Worcester, Massachusetts 01605, USA
Nature 467:977-81. 2010..These results assign crucial functions to the maternal deposit of Rnf12/RLIM for the initiation of imprinted XCI...
Unbalanced X;autosome translocations provide evidence for sequence specificity in the association of XIST RNA with chromatinLisa L Hall
Department of Cell Biology, University of Massachusetts Medical School, Worcester, MA 01655-0106, USA
Hum Mol Genet 11:3157-65. 2002..Hence compromised interaction with XIST RNA may be a primary cause of incomplete or unstable autosomal inactivation...
The X chromosome is organized into a gene-rich outer rim and an internal core containing silenced nongenic sequencesChristine Moulton Clemson
Department of Cell Biology, University of Massachusetts Medical Center, 55 Lake Avenue North, Worcester, MA 01655, USA
Proc Natl Acad Sci U S A 103:7688-93. 2006..Instead of acting at a local gene level, XIST RNA appears to interact with and silence core architectural elements to effectively condense and shut down the Xi...
The disappearing Barr body in breast and ovarian cancersGayle J Pageau
Department of Cell Biology, University of Massachusetts Medical School, Worcester, Massachusetts 01655, USA
Nat Rev Cancer 7:628-33. 2007..We suggest that heterochromatic instability is a common but largely unexplored mechanism, leading to widespread genomic misregulation and the evolution of some cancers...
c-Myc localization within the nucleus: evidence for association with the PML nuclear bodyKelly P Smith
Department of Cell Biology, University of Massachusetts Medical School, 55 Lake Avenue North, Worcester, Massachusetts 01655, USA
J Cell Biochem 93:1282-96. 2004..This work provides a comprehensive study of c-Myc distribution and also presents the first evidence of a relationship between turnover of this oncoprotein and PML nuclear bodies, known to break down in certain cancers...
Changing nuclear landscape and unique PML structures during early epigenetic transitions of human embryonic stem cellsJohn T Butler
Department of Cell Biology, University of Massachusetts Medical School, Worcester, 01655, USA
J Cell Biochem 107:609-21. 2009..Findings demonstrate that pluripotent hES cells have a markedly different overall nuclear architecture, remodeling of which is linked to early epigenomic programming and involves formation of unique PML-defined structures...
Loss of miRNA biogenesis induces p19Arf-p53 signaling and senescence in primary cellsRajini Mudhasani
Department of Cell Biology, University of Massachusetts Medical School, North Worcester, MA 01655, USA
J Cell Biol 181:1055-63. 2008..These results reveal that loss of miRNA biogenesis activates a DNA damage checkpoint, up-regulates p19(Arf)-p53 signaling, and induces senescence in primary cells...
Word frequency analysis reveals enrichment of dinucleotide repeats on the human X chromosome and [GATA]n in the X escape regionJohn A McNeil
Department of Cell Biology, University of Massachusetts Medical School, Worcester, Massachusetts 01655, USA
Genome Res 16:477-84. 2006..Results suggest a new paradigm whereby a regional escape from X inactivation is due to the presence of elements that prevent heterochromatinization, rather than the lack of other elements that promote it...
Inducible XIST-dependent X-chromosome inactivation in human somatic cells is reversibleJennifer C Chow
Department of Medical Genetics, Molecular Epigenetics Group, University of British Columbia, 2350 Health Sciences Mall, Vancouver, BC, Canada
Proc Natl Acad Sci U S A 104:10104-9. 2007....
