Gene amplification as a developmental strategy: isolation of two developmental amplicons in DrosophilaJulie M Claycomb
Whitehead Institute and Department of Biology, Massachusetts Institute of Technology, Cambridge, MA 02142, USA
Dev Cell 6:145-55. 2004..Thus, during follicle cell differentiation the entire genome is overreplicated as the cells become polyploid, and subsequently specific genomic intervals are overreplicated to facilitate gene expression...

Comparative genomic analysis of novel conserved peptide upstream open reading frames in Drosophila melanogaster and other dipteran speciesCeline A Hayden
Department of Molecular and Cellular Biology, University of Arizona, Tucson, AZ 85721, USA
BMC Genomics 9:61. 2008..In Drosophila, approximately 40% of transcripts contain upstream start codons (uAUGs) but there is little evidence that these are translated and affect their associated mORF...
Analysis of Drosophila species genome size and satellite DNA content reveals significant differences among strains as well as between speciesGiovanni Bosco
Department of Molecular and Cellular Biology, University of Arizona, Tucson, Arizona 85721, USA
Genetics 177:1277-90. 2007..Addition and loss of heterochromatin satellite repeat elements appear to have made major contributions to the large differences in genome size observed in the Drosophilidae...
Chromosome alignment and transvection are antagonized by condensin IITom A Hartl
Department of Molecular and Cellular Biology, University of Arizona, 1007 East Lowell Street, Tucson, AZ 85721 0106, USA
Science 322:1384-7. 2008..We propose that condensin II restricts trans-chromosomal interactions that affect transcription through its ability to spatially separate aligned interphase chromosomes...
Genetic and systems level analysis of Drosophila sticky/citron kinase and dFmr1 mutants reveals common regulation of genetic networksChristopher R Bauer
Department of Molecular and Cellular Biology, University of Arizona, Tucson, Arizona, USA
BMC Syst Biol 2:101. 2008..Given these genetic and functional similarities, we tested Drosophila sticky and dFmr1 for a genetic interaction and measured whole genome expression in both mutants to assess similarities in gene regulation...
Condensin II promotes the formation of chromosome territories by inducing axial compaction of polyploid interphase chromosomesChristopher R Bauer
Department of Molecular and Cellular Biology, The University of Arizona, Tucson, Arizona, United States of America
PLoS Genet 8:e1002873. 2012..These Condensin II activities compartmentalize the nucleus into discrete chromosome territories and indicate commonalities in the mechanisms that regulate the spatial structure of the genome during mitosis and interphase...
The N-terminal domain of the Drosophila retinoblastoma protein Rbf1 interacts with ORC and associates with chromatin in an E2F independent mannerJoseph Ahlander
Department of Molecular and Cellular Biology, University of Arizona, Tucson, Arizona, United States of America
PLoS ONE 3:e2831. 2008..The retinoblastoma (Rb) tumor suppressor protein can function as a DNA replication inhibitor as well as a transcription factor. Regulation of DNA replication may occur through interaction of Rb with the origin recognition complex (ORC)...
Sqd interacts with the Drosophila retinoblastoma tumor suppressor RbfJoseph Ahlander
Department of Molecular and Cellular Biology, University of Arizona, Tucson, 85721, USA
Biochem Biophys Res Commun 383:363-7. 2009..We conclude from our studies that Rbf physically and genetically interacts with Sqd. We propose that the retinoblastoma tumor suppressor may play a novel role in RNA processing through interaction with RNA-binding proteins...
Drosophila Fragile X protein controls cellular proliferation by regulating cbl levels in the ovaryAndrew M Epstein
Department of Molecular and Cellular Biology, Life Sciences South, University of Arizona, Tucson, AZ 85721, USA
Dev Biol 330:83-92. 2009..These data support a model whereby FMRP controls germline proliferation by regulating the expression of cbl in the developing ovary...
Condensin II resolves chromosomal associations to enable anaphase I segregation in Drosophila male meiosisTom A Hartl
Department of Molecular and Cellular Biology, University of Arizona, Tucson, Arizona, United States of America
PLoS Genet 4:e1000228. 2008..Furthermore, persistence of homologous and heterologous interchromosomal associations lead to anaphase I chromatin bridging and the generation of aneuploid gametes...
Drosophila sticky/citron kinase is a regulator of cell-cycle progression, genetically interacts with Argonaute 1 and modulates epigenetic gene silencingSarah J Sweeney
Department of Molecular and Cellular Biology, University of Arizona, Tucson, Arizona 85721, USA
Genetics 178:1311-25. 2008....
Developmentally regulated histone modifications in Drosophila follicle cells: initiation of gene amplification is associated with histone H3 and H4 hyperacetylation and H1 phosphorylationTom Hartl
Department of Molecular and Cellular Biology, Arizona Cancer Center, University of Arizona, Tucson, AZ 85724, USA
Chromosoma 116:197-214. 2007..These data suggest that amplification origins are able to initiate when the cells are in a late S-phase, when the genome is normally not licensed for replication...
The RB/E2F pathway and regulation of RNA processingJoseph Ahlander
Department of Molecular and Cellular Biology, 1007 East Lowell Street, University of Arizona, Tucson, AZ 85721, USA
Biochem Biophys Res Commun 384:280-3. 2009..The elucidation of a novel role of RB in RNA processing will have a profound impact on our understanding of the role of this tumor suppressor family in cell and developmental biology...
