Fowlks and Campbell presented their perspectives on the undergraduate educational implications of the NIH Roadmap. Fowlks addressed curricular changes in undergraduate biology, as well as recruitment and training for underrepresented populations. Campbell provided an overview of activities by GCAT, a non-profit educational consortium, to bring functional genomics methods into undergraduate courses and independent student research. After the presentations, an invited representative of NSF encouraged Dr. Fowlks and Dr. Campbell to submit a proposal that would provide a microarray workshop opportunity for undergraduate faculty at minority serving institutions (MSIs). The 2005 GCAT workshop at Morehouse College was an overwhelming success based on participant and instructor evaluations (see Outcomes of Previous Workshops below), as well as comments from two NSF Program Officers (POs) who attended part of the workshop. These POs encouraged Fowlks, Campbell, and their GCAT colleagues to submit a three-year proposal for DNA microarray workshops that would have a significant impact on the introduction of genomics in undergraduate curricula, especially in MSIs. On the advice of the POs, this collaborative proposal brings Hampton University as the lead institution with Davidson College as the collaborative institution. Fowlks and Heyer will co-chair the advisory board which will focus on participant recruitment (emphasizing faculty from MSIs). Fowlks also will oversee workshop housing, transportation, and on-site facilities logistics while Campbell will focus on wet- and dry-lab curriculum, recruitment of instructors, and organization of the workshop technical aspects. As described in the budget justification, the budget will be divided according to these two functional roles. History of Genomics and GCAT Genomics first grabbed the headlines with the Human Genome Project. This monumental task was the beginning of a long process to understand how humans work. The production of any genome sequence is analogous to creating a periodic table for the chemical elements – a great start but ultimately only a parts list, failing to explain how the parts interact. Experimental data are needed to illuminate how all the genes work synergistically. One way to measure every gene’s activity simultaneously is to use DNA microarrays. DNA microarrays are produced by printing one spot of DNA for each gene onto a specially coated glass microscope slide. Each spot contains a unique DNA sequence specific for only one gene. For example, a yeast DNA microarray is composed of ~ 6,500 spots – one for each of its 6,500 genes. The investigator isolates the mRNAs and couples one color fluorescent dye to the mRNAs for one growth condition. In parallel, the investigator isolates and labels with a different color the mRNAs isolated from cells grown under a different condition. The two populations of differently colored mRNAs are mixed and allowed to base pair with the appropriate genes among the 6,500 spots on the microarray. The fluorescence for each color on every spot is quantified to produce a ratio of mRNA binding from the two growth conditions. From this list of 6,500 ratios, the investigator can determine which genes are activated and which ones are repressed in the two growth conditions (see an animated version here: <www.bio.davidson.edu/Courses/genomics/chip/chip.html>). Measuring the genomic transcriptional response to different growth conditions is a critical step in understanding how each gene contributes to the genome’s combinatorial functional capacity. GCAT was conceived in December 1998 by Dr. A. Malcolm Campbell (Davidson College) and Dr. Mary Lee Ledbetter (College of the Holy Cross), who were inspired by Dr. Patrick Brown’s talk at the 39th Annual meeting of the American Society of Cell Biology regarding his pioneering work on DNA microarrays. DNA microarray technology has revolutionized the investigation of gene expression at the genomic level, and holds great promise for understanding the complex, systems-level regulation in many species. Many job opportunities in academia and industry are available for trained college graduates. Furthermore, the best graduate programs are looking for students with practical experience. However, microarray technology is inaccessible to many undergraduates because of limitations in funding and faculty expertise. GCAT’s mission is to make such experiments accessible to all undergraduates and we are succeeding: since 2000, about 5,000 undergraduates have performed experiments with DNA microarrays obtained through GCAT and analyzed their results with free software developed by co-PI Laurie Heyer and her undergraduate students (www.bio.davidson.edu/MAGIC). GCAT makes microarray experiments affordable through cost-sharing, provides a clearinghouse of information, raw data and analyzed results for use in teaching genomics, and represents a network of mutually supportive teachers using functional genomics.

  • The Role of Histone H2av Variant Replacement and Histone H4 Acetylation in the Establishment of Drosophila Heterochromatin
    The role of histone H2Av variant replacement and histone H4 acetylation in the establishment of Drosophila heterochromatin Jyothishmathi Swaminathan, Ellen M. Baxter, and Victor G. Corces1 Department of Biology, Johns Hopkins University, Baltimore, Maryland 21218, USA Activation and repression of transcription in eukaryotes involve changes in the chromatin fiber that can be accomplished by covalent modification of the histone tails or the replacement of the canonical histones with other variants. Here we show that the histone H2A variant of Drosophila melanogaster, H2Av, localizes to the centromeric heterochromatin, and it is recruited to an ectopic heterochromatin site formed by a transgene array. His2Av behaves genetically as a PcG gene and mutations in His2Av suppress position effect variegation (PEV), suggesting that this histone variant is required for euchromatic silencing and heterochromatin formation. His2Av mutants show reduced acetylation of histone H4 at Lys 12, decreased methylation of histone H3 at Lys 9, and a reduction in HP1 recruitment to the centromeric region. H2Av accumulation or histone H4 Lys 12 acetylation is not affected by mutations in Su(var)3-9 or Su(var)2-5. The results suggest an ordered cascade of events leading to the establishment of heterochromatin and requiring the recruitment of the histone H2Av variant followed by H4 Lys 12 acetylation as necessary steps before H3 Lys 9 methylation and HP1 recruitment can take place.

  • TALE-Light Imaging Reveals Maternally Guided, H3k9me2/3-Independent Emergence of Functional Heterochromatin in Drosophila Embryos
    Downloaded from genesdev.cshlp.org on September 29, 2021 - Published by Cold Spring Harbor Laboratory Press TALE-light imaging reveals maternally guided, H3K9me2/3-independent emergence of functional heterochromatin in Drosophila embryos Kai Yuan and Patrick H. O’Farrell Department of Biochemistry, University of California at San Francisco, San Francisco, California 94158, USA Metazoans start embryogenesis with a relatively naïve genome. The transcriptionally inert, late-replicating het- erochromatic regions, including the constitutive heterochromatin on repetitive sequences near centromeres and telomeres, need to be re-established during development. To explore the events initiating heterochromatin forma- tion and examine their temporal control, sequence specificity, and immediate regulatory consequence, we estab- lished a live imaging approach that enabled visualization of steps in heterochromatin emergence on specific satellite sequences during the mid-blastula transition (MBT) in Drosophila. Unexpectedly, only a subset of satellite se- quences, including the 359-base-pair (bp) repeat sequence, recruited HP1a at the MBT. The recruitment of HP1a to the 359-bp repeat was dependent on HP1a’s chromoshadow domain but not its chromodomain and was guided by maternally provided signals. HP1a recruitment to the 359-bp repeat was required for its programmed shift to later replication, and ectopic recruitment of HP1a was sufficient to delay replication timing of a different repeat. Our results reveal that emergence of constitutive heterochromatin follows a stereotyped developmental program in which different repetitive sequences use distinct interactions and independent pathways to arrive at a heterochro- matic state. This differential emergence of heterochromatin on various repetitive sequences changes their replica- tion order and remodels the DNA replication schedule during embryonic development.

  • Drosophila Ribosomal Proteins Are Associated with Linker Histone H1 and Suppress Gene Transcription
    Downloaded from genesdev.cshlp.org on October 2, 2021 - Published by Cold Spring Harbor Laboratory Press Drosophila ribosomal proteins are associated with linker histone H1 and suppress gene transcription Jian-Quan Ni,1,3 Lu-Ping Liu,1,3 Daniel Hess,1 Jens Rietdorf,1 and Fang-Lin Sun1,2,4 1Friedrich Miescher Institute for Biomedical Research, Basel CH-4058, Switzerland; 2Institute of Epigenetics and Cancer Research, School of Medicine, Tsinghua University, Beijing 100080, China The dynamics and function of ribosomal proteins in the cell nucleus remain enigmatic. Here we provide evidence that specific components of Drosophila melanogaster ribosomes copurify with linker histone H1. Using various experimental approaches, we demonstrate that this association of nuclear ribosomal proteins with histone H1 is specific, and that colocalization occurs on condensed chromatin in vivo. Chromatin immunoprecipitation analysis confirmed that specific ribosomal proteins are associated with chromatin in a histone H1-dependent manner. Overexpression of either histone H1 or ribosomal protein L22 in Drosophila cells resulted in global suppression of the same set of genes, while depletion of H1 and L22 caused up-regulation of tested genes, suggesting that H1 and ribosomal proteins are essential for transcriptional gene repression. Overall, this study provides evidence for a previously undefined link between ribosomal proteins and chromatin, and suggests a role for this association in transcriptional regulation in higher eukaryotes.

Using a versatile curriculum, GEP undergraduates undertake projects to improve draft genomic sequences and/or participate in the annotation of these improved sequences. An additional goal of the annotation curriculum is for students to gain a sophisticated understanding of eukaryotic gene structure. Students do so by carefully mapping the protein-coding regions of putative genes from recently- sequenced Drosophila species.

  • Heterochromatin-Associated Interactions of Drosophila Hp1a with Dadd1, HIPP1, and Repetitive Rnas

Here we identify chromatin-associated protein and RNA interactions of HP1a by BioTAP-XL mass spectrometry and sequencing from Drosophila S2 cells, embryos, larvae, and adults. Our results reveal an extensive list of known and novel HP1a-interacting proteins, of which we selected three for validation. A strong novel interactor, dADD1 (Drosophila ADD1) (CG8290), is highly enriched in heterochromatin, harbors an ADD domain similar to human ATRX, displays selective binding to H3K9me2 and H3K9me3, and is a classic genetic suppressor of position-effect variegation. Unexpectedly, a second hit, HIPP1 (HP1 and insulator partner protein-1) (CG3680), is strongly connected to CP190-related complexes localized at putative insulator sequences throughout the genome in addition to its colocalization with HP1a in heterochro- matin.

Driving Gene Expression in the Heterochromatic Environment of the Fourth Chromosome of D. melanogaster Jacob Cantrell Mentor: Sarah Elgin Genomes of higher eukaryotes can be divided into two fundamental and dynamic subtypes: euchromatin and heterochromatin. The fourth chromosome of Drosophila melanogaster is of particular interest because, despite the fact that it appears to be entirely heterochromatic, the genes within this densely packaged chromosome are expressed. Genes that are active in a euchromatic environment are silenced when transposed to heterochromatin. Our aim is to identify heterochromatic gene regulatory elements that drive their active transcription. Insertion of a euchromatic hsp70-white transgene, which exhibits a uniform red eye phenotype when present in euchromatin, into heterochromatic regions on the fourth chromosome results in sporadic silencing, or Position Effect Variegation (PEV).

  • Technological Breakthroughs Transform Biological Inquiry in Neuroscience
    A Magazine | The School of Molecular and Cellular Biology at the University of Illinois at Urbana-Champaign | Issue 10, 2017 MCB TECHNOLOGICAL BREAKTHROUGHS TRANSFORM BIOLOGICAL INQUIRY IN NEUROSCIENCE College of Liberal Arts and Sciences LETTER FROM THE DIRECTOR Fifty-three years ago, Bob Dylan released the song “The Times They Are a Changin’.” Today, times are indeed different at the University of Illinois. Many of you know that I earned my Ph.D. in Physics in the College of Engineering here, matriculating in 1970. This was the height of the VietnamWar and the draft took several fellow graduate students – some not returning, while others were forced to change from experiment to theory due to loss of multiple limbs. Those were polarized times, and they remain so. The campus is putting in place financial models that call for a reduced reliance on the State for resources. Despite these challenges, MCB remains a bright and shining jewel. Campus resources are committed to two exciting academic projects: A new Carle-Illinois College of Medicine and a cross-campus Siebel Design Center. MCB will play important roles in these and other initiatives. The School of MCB is on solid financial ground, with high demand for the MCB major and undergraduate enrollments limited only by the availability of instructional space. The research prowess of MCB faculty has translated into MCB Dr. Stephen G. Sligar leading in the receipt of external funding from the National Institutes of Health, the main source of the United States investment in health related research. That said, we increasingly rely on support from our alumni and friends, as demonstrated in several articles in this issue of the MCB Magazine.
