Special Interest Subgroup Meetings
Saturday, December 11
Washington Convention Center
1:00 PM — 5:00 PM

 

Cell Biological Applications of Atomic Force Microscopy
Subgroup A — Room 13
Organizers: Jan Hoh, Johns Hopkins University School of Medicine and Vincent Moy, University of Miami School of Medicine

The atomic force microscope (AFM) is emerging as a powerful tool in cell biology. The aim of this subgroup session is two-fold: to educate the non-specialist in how the AFM works and how it is being used, and to present recent results at the cutting edge of the technology. The session will begin with a general introduction to the instrumentation and basic modes of operation. This will be followed by presentations in five general application areas. Each of these presentations will begin with a general introduction, followed by recent results in that area.

  • Introduction to atomic force microscopy. Jan H. Hoh, Johns Hopkins University School of Medicine
  • Imaging proteins and membranes. Michael Allen, Biometrology, Inc.
  • Imaging chromatin and nucleic acids. Eric Henderson, Iowa State University

Cellular Biology of Gap Junction Channels
Subgroup B — Room 36
Organizers: Linda Musil, Vollum Institute and Andrew Harris, New Jersey Medical School of UMDNJ

Present in virtually all cell types in animals ranging from coelenterates to humans, gap junctions are involved in a variety of fundamental processes including regulation of cellular differentiation, growth control, embryonic development and specialized tissue function. Defects in the proteins that comprise gap junctions (connexins) have recently been linked to several human diseases. The proposed session will be the 7th consecutive meeting for this well-attended subgroup at ASCB and will address new developments in our understanding of gap junction diversity, assembly, regulation, channel structure/function, and role in physiological processes.

In Vitro Myogenesis: Models of Development and Disease
Subgroup C — Room 10
Organizers: Joseph W. Sanger, University of Pennsylvania School of Medicine and Tom Borg, University of South Carolina Medical School

Central to the form and function of muscle are the myofibrils that provide the cytoskeletal structure and the contractile force. Despite all that has been learned about myofibrillogenesis over the last 100 years, the challenges of identifying the essential steps involved in this process and of understanding how the process is initiated and controlled are still unmet. A major approach has been to culture cells from embryonic, neonatal or adult cardiomyocytes. This session will present several short talks on the use of different systems and approaches to study myofibrillogenesis. Audience participation will be encouraged by a general discussion of myofibrillogenesis at the end of the platform presentations.

Latest Technical Developments in Live Cell Imaging with GFP
Subgroup D — Room 38
Organizers: Roland Eils, Hans-Hermann Gerdes, University of Heidelberg; Peter Sorger, Massachusetts Institute of Technology; Jason R. Swedlow, University of Dundee

Subgroup D Schedule of Talks
Several converging developments have sparked a revolution in live cell imaging. First, the development of green fluorescent protein (GFP) as a molecular reagent has allowed virtually any protein to be tagged fluorescently in a living cell. The generation of GFP mutants including spectral variants with red- and blue-shifted fluorescence has allowed multiple cellular components to be imaged simultaneously and has led to exciting insights into cellular dynamics. Second, recent developments in imaging techniques and automated time-resolved image analysis have made sophisticated and computation-intensive image processing accessible to most cell biologists.

It is now routine to record the dynamic behavior of proteins in living cells. However, most of the analysis of these time-lapse images to date has been limited to simple visual interpretation - just watching movement and changes in distribution, and then commenting on them.

This subgroup meeting will focus on an emerging field–the quantitative numerical analysis of cellular dynamics. Presentations drawn from a diverse body of cell biological areas will focus on technical aspects related to four major areas of interest:

  1. High resolution and high speed dual color imaging of membrane traffic.
  2. 4D-imaging and analysis of cytoskeletal and nuclear dynamics.
  3. Protein-protein interactions using FRET (fluorescence resonance energy transfer) and FLIM (fluorescence life time imaging).
  4. Hard- and software for live cell imaging and quantitative image analysis.

    Speakers and topics include:

    • Dual color time lapse imaging of different GFP variants to study protein traffic. Jennifer Lippincott-Schwartz, NICHD, NIH, Bethesda
    • Studying subnuclear dynamics in living cells. David L.S. Spector, Cold Spring Harbor Laboratory.
    This subgroup will be of interest to all cell biologists who are pursuing in vivo studies of cellular dynamics and to anyone concerned with the quantitative analysis of fluorescence objects. A detailed schedule will be available onsite.

Refreshments will be served.

MAGUKs and PDZs
Subgroup E — Room 25
Organizer: Peter J. Bryant, Developmental Biology Center, University of California, Irvine

Membrane-associated Guanylate Kinase homologs (MAGUKs) appear to be an important class of scaffolding proteins responsible for clustering and organizing transmembrane proteins and other elements of signal transduction pathways in animal cells. One of the common protein interaction domains in MAGUKs, called the PDZ domain, also exists in a large number of other proteins where it also mediates protein-protein interaction. This meeting will explore the diversity of these proteins and domains, especially the question of whether the protein interactions are dynamic and regulated, and, if so, what other molecules are important for these regulatory mechanisms. 20-minute presentations will include time for questions.

  • Introduction. Peter J. Bryant, University of California, Irvine
  • PDZs and related modules in asymmetric cell division. Tony Pawson, Samuel Lunenfeld Research Institute, Mount Sinai Hospital, Toronto

Mechanisms of Cell Division as Revealed by Imaging Studies
Subgroup F — Room 27
Organizers: Donald C. Chang, Hong Kong University of Science & Technology and Joseph W. Sanger, University of Pennsylvania School of Medicine

Cell division is a very important process in cell biology. The mechanisms of cell division are currently under active investigation. One of the most useful approaches is to use imaging techniques with which one can study the dynamic distribution and reoganization of critical molecules in living cells. Recently, great progress has been made in developing new imaging methods (including GFP and new fluorescent indicators) that have significantly increased the power of the imaging techniques. Using these techniques, we have obtained new insight into the cellular mechanisms that control the various mitotic events. It will be of interest to the cell biology community to know about this recent progress. Furthermore, this subgroup meeting will serve as a useful forum for investigators to share their current views on the most critical issues involved in the regulation of cell division.

Speakers:

  • Dynamics of cytoskeletal proteins during cytokinesis. Jean Sanger and Joseph W. Sanger, University of Pennsylvania School of Medicine
  • Fluorescent speckle microscopy of microtubule dynamics and chromosome movements with emphasis on budding yeast. Paul Maddox, Chad Pearson, Kerry Bloom and E. D. Salmon, University of North Carolina

  • Terminal phase of cytokinesis in C. elegans requires secretion. Ahna Skop and John G. White, University of Wisconsin

    General discussion: What are the major issues in cell division now?

Membrane Fusion: Machinery and Mechanism
Subgroup G — Room 37
Organizer: Bhana Pratap Jena, Yale University

Membrane fusion is a fundamental cellular process regulating intracellular transport, neurotransmission, enzyme secretion and hormone release, to name a few. Additionally, knowledge of how opposing bilayers fuse will further our understanding of cellular entry/exit of viruses, and provide us with the facts to develop the next generation of drug delivery systems. In the last decade and especially in the last year or two, great strides have been made in our understanding of the molecular machinery and mechanism of membrane fusion. This Special Interest Subgroup will bring together investigators in the field to discuss and participate with experts in the area. Several speakers who are investigators in the field will cover new developments and discuss some of the emerging technology helping in the study of this vital cellular process.

Raftology: Lipid Microdomains and Membrane Function

Subgroup H — Room 14

Organizers: Michael J. Saxton, University of California, Davis, David Holowka, Cornell University, and Chiara Zurzolo, University of Naples

Lipid rafts – detergent-insoluble membrane microdomains enriched in glycosphingolipids and cholesterol – are thought to be involved in signal transduction and in membrane protein sorting. Species involved in signaling, such as GPI-linked proteins and src kinases, are associated with rafts. But the existence and nature of these structures are controversial, in part because they may be transient. Rafts raise fundamental questions: to what extent does the classic Singer-Nicolson model of the membrane need to be modified to allow for heterogeneity? to what extent is lateral organization of the plasma membrane involved in cell function? The proposed session will examine the nature of rafts, as well as their role in signaling and sorting.

Topics and speakers include:

  • Organization of raft lipids and proteins. Deborah A. Brown, SUNY Stony Brook
  • A 3-component phase diagram: relevant to rafts? Gerald W. Feigenson, Cornell University
  • Lipid raft structure visualized with sub-micron resolution. Anne K. Kenworthy, Johns Hopkins University
  • Single-particle tracking and rafts. Ken Jacobson, University of North Carolina
  • Rafts: facts and fancy. Kai Simons. EMBL, Heidelberg

Targeted Proteomics in Cell and Molecular Biology
Subgroup I — Room 15
Organizer: Paul Tempst, Memorial Sloan-Kettering Cancer Center

Completion of the genome project will lead to an even bigger challenge, interpreting the fluxes and flows of material and signals that result in cell behavior. Protein science should play a major role in this endeavor, simply because proteins carry out most of the work in a cell. A new term, proteomics, has been introduced to describe what many expect will be the future of protein structural chemistry. In the present vernacular, the term seems synonymous with attempts to map all proteins in every cell using two-dimensional gels and high-throughput mass spectrometry. But even on a smaller scale, our knowledge of protein-protein, protein-DNA and protein-small molecule interactions is still far from complete. Thus, an immediate task is to find out which proteins bind to what other molecules in the cell, and to examine how the composition of such complexes might shift in response to cellular signals, natural ligands and drugs. This field has been termed targeted proteomics.

Speakers will describe approaches to purify or specifically capture protein complexes on a micro-scale, and how to identify the components by mass spectrometric analysis of fragments. Several experts will then discuss how these discoveries have advanced our understanding of biological systems in their respective fields of interest.

Topics and speakers include:

  • Actin-binding proteins in the development of C. elegans. Raffi Aroian, UC San Diego
  • Chromatin remodeling machines in transcriptional regulation. Bradley Cairns, University of Utah
  • A decade long story of NF-kappaB. Sankar Ghosh, Yale University
  • SNAREs in vesicle targeting and fusion. Thomas Söllner, Sloan-Kettering
  • Practical aspects of protein mass spectrometry. Paul Tempst, Sloan-Kettering

Visualizing the Cytoskeleton and Signaling in Mechanically Stimulated Cells
Subgroup J — Room 23
Organizers: Albert J. Banes and Carol Otey, University of North Carolina

The response of cells to mechanical deformation is now an accepted phenomenon in cell biology as well as biomechanics. In response to applied mechanical load, cells signal using Ca2+, 1P3, cAMP, ATP and other purines, as well as activate components of kinase pathways such as MAPK, JAK/STAT and JNK pathways. Multiple transcription factors can be activated driving specific gene expression dependent on the CRLs in a given promoter. One of the important early/intermediate events in response to strain is a reaction of the existing cytoskeleton to polymerize actin and rearrange cell shape. The focus of this subgroup meeting will be on visualizing signaling events and cytoskeletal changes that occur in response to mechanical load. Emphasis will be placed on cell responses to tension, compression and shear stress-induced cytoskeletal changes, blocking experiments to KO components of the cytoskeleton or signaling pathways and over expression strategies that upregulate proteins involved in a response. Talks will include diverse approaches of load applications, cell types and methods to measure changes in cell expression.

Speakers will include:

  • Albert J. Banes, University of North Carolina
  • Carol Otey, University of North Carolina
  • Traction forces of cell movement & cortical flow. Kevin Burton, Massachsetts General Hospital/Harvard Medical School
  • Tensegrity and the mechanical behaviors of the cytoskeleton. Steve Heidemann, University of Michigan
  • Locomotion, contraction and proliferation of fibroblasts in a model ECM. G. Steven Vanni, Elisabeth Nadolny and Frederick Lanni, Carnegie Mellon University.
  • ATP release by mechanically stimulated chondrocytes in pellet culture. Ron Graff. University of North Carolina

Supported by an educational grant from Flexcell Corp.

Letters To The Editor

Siekevitz Profile

To the Editor:

The profile of Philip Siekevitz (August, 1999 ASCB Newsletter) was very well done, capturing both the scientist and the delightful intellectual beyond cell biology. But one of the subject's career steps was covered too briefly, namely his seminal role in achieving cell-free protein synthesis in the laboratory of Paul Zamecnik (not Zameenik, as misspelled in the article). Siekevitz was a major player in winning acceptance of cell-free protein synthesis as a valid workbench for molecular biology.

–Thoru Pederson


To the Editor:

I enjoyed your interesting and informative profile on Phil Siekevitz. However, I did catch a small error. Dr. Siekevitz was not "the editor of the first cell biology textbook in 1963, called Cell Structure and Function;" he was co-author of this book.

Sincerely yours,

–Ariel G. Loewy

Editor's Note: The coauthors of the three editions of Cell Structure and Function are:

First ed. 1963. Ariel G. Loewy and Philip Siekevitz
Second ed. 1969. Ariel G. Loewy and Philip Siekevitz
Third ed. 1991. Ariel G. Loewy, Philip Siekevitz, John R. Menninger and Jonathan A. R. Gallant


To the Editor:

Thank you for the flattering profile on me in the August issue of the ASCB Newsletter. In addition to the correction that my colleague Ariel Loewy has sent you, please note that I sought advice on mitochondrial biochemistry from Fritz Lipmann's lab but did not collaborate with the lab. Also, my lab was the first to use isolated subcellular fractions, such as mitochondria and microsomes, in in vitro protein synthesis.

Sincerely,

–Philip Siekevitz


Stem Cell Policy Challenged

Dear Ms. Marincola:

I am writing as a member of the ASCB to pro-test the ACSB position on stem cell research as reported in the [April 1999] ASCB Newsletter. This position covers an area governed by morality and ethics – issues involving the protection of human life. As such, its enunciation implies its support by the Society, and by extension, by the members of the Society.

In my opinion:

  1. The fact of research on these human stem cells, those derived ultimately from human embryos, presupposes that their initial isolation is legitimate. In fact, such isolation is immoral since the destruction of a human being is necessary for the start of such work.
  2. To allow the use of the these cells while admitting that a human being is destroyed in their isolation would be an obscenity, regardless of whether the use of these cells would benefit anyone.
  3. Positions of the Society are decided by members of the Council, yet the signatures on the letter in question are not those of the Council, but rather those of numerous Nobel laureates. The decision appears to have come from an oligarchy, not from the duly elected leaders of ASCB.
  4. The group signing their support for this position are, in the great majority, men. Since the abuse of women through our present culture of abortion is largely perpetrated by men, the representation of this list highlights the lack of concern for human life on the part of the signatories.

In enunciating this position on human stem cell research, I believe that the ASCB has abdicated its responsibility to provide moral and ethical leadership and is promoting instead an immoral policy.

Sincerely,

–Douglas W. Darnowski

Editor's Note: The Council of the ASCB did approve the position as endorsed by 36 Nobel laureates.

Zheng will receive the Junior Award. She is recognized for outstanding scientific contributions including the successful cloning of microtubule nucleation components from both Xenopus and Drosophila, and forher studies of their expressed, pure proteins and their complexes.

The WICB Awards will be presented at the lunch sponsored by the ASCB WICB and Education Committees on Monday, December 13, at the upcoming ASCB Annual Meeting.

 


Alberts Award Recognizes Evolution Defender
  10/01/1999

Eugenie Scott
Eugenie Scott, Executive Director of the National Center for Science Education, has been named the second ASCB-Bruce Alberts Award winner by the Society's Education Committee.

Scott was nominated for her dedication to protecting the teaching of evolution through writing, speeches, media appearances and, importantly, presentations to school boards, teachers, churches and parents.

The teaching of evolution recently suffered a serious setback in the State of Kansas. Evolution defenders and detractors are watching the Kansas decision closely to see if it stands and/or establishes a precedent for other states.

Bruce Alberts, President of the National Academy of Sciences, will present the Award to Scott on Sunday, December 12 at 9:45 a.m. at the 39th ASCB Annual Meeting in Washington.

 


Former ASCB President Wins Nobel Prize
  10/01/1999

Gunter Blobel of the Rockefeller University, President of the Society in 1989, will receive the 1999 Nobel Prize in Physiology or Medicine.

Blobel was cited for his work in protein signaling, which led to understanding of the molecular roots of many diseases, including primary hyperoxaluria, which causes kidney stones at a young age, as well as some forms of high cholesterol and illnesses such as cystic fibrosis that occur when proteins fail to reach proper positions within the cell.

Blobel, a native of Germany, will receive the prize in Stockholm this December.

 


WWW.Cell Biology Education
  10/01/1999

The ASCB Education Committee calls attention each month to Web sites of educational interest to the cell biology community. The Committee does not endorse nor guarantee the accuracy of the information at any of the listed sites. If you wish to comment on the selections or suggest future inclusions please send a message to Robert Blystone.

  1. Life Science.Connect
    This new international Web site seeks to reorganize the Life Science community based on the Internet's ability to provide for data exchange at low cost and high speed. "This community will then have the opportunity to create new ventures that reflect the open democracy and transparency that this new form of communication can provide." Among the many initial supporters of the project are Jim Jamieson, former ASCB President, and Sam Silverstein, former FASEB President.

    The homepage of the site provides ten paths including a directory, magazine, journal access, jobs, Ph.D programs, meetings, and links. The magazine is to begin in October and post graduate offerings in November. A wide range of meeting dates were listed but unfortunately did not contain reference to the ASCB Annual Meeting. The journal section will ultimately connect to electronic journals. The jobs section is extensive and worldwide in its focus. There are only six links in the Links section, but they are excellent choices. The site is clearly nascent in its nature; however, given the group supporting this effort, it is a site to bookmark should your interests follow developments in molecular biology.

  2. PubMed Central
    A few months ago Harold Varmus stirred the publishing world by suggesting that cell and molecular biology data should be quickly and inexpensively available on the Web. To say the least, passions were raised. PubMed Central is the first shot over the bow in this effort to change the way research data is disseminated. As was the case with the first selection above, this is a nascent site. To quote the introductory narrative at the site: "In an effort to put the system into operation, the NIH will establish a Web-based repository for barrier-free access to primary reports in the life sciences. This repository, which we consider to be the initial site in an international system, [emphasis added] will be called PubMed Central, based on its natural integration with the existing PubMed biomedical literature database. PubMed itself will extend its coverage of the life sciences and continue its linkage to external online journals." You may want to visit PubMed to read the text of the proposal about the electronic publishing of research data.
  3. NIH Office of Science Education
    This is "... a Web site for high school students and teachers dedicated to bringing cutting edge biomedical research into science classrooms. This site is a creation of the Office of Science Education of the National Institutes of Health (NIH) in Bethesda, Md. The effort is funded by the NIH Office of Research on Women's Health." To this end, the site is very successful.

    The home page opens with three broad area selections: 1) six paths, 2) a poster titled "Women are surgeons" and 3) Snap Shots. Be prepared to spend some time with Snap Shots. It is a fascinating collection of stories, information and science news. Do you know who Elizabeth Blackwell was? The story of the first American female M.D. is wonderful. Snap Shots contain great features titled "Bacteria Cause Ulcers", "Animal Parts for People", and "Spinal Cord Injuries." There are features on very interesting people doing science, all kinds of science.

    The six paths section has information entitled "For Teachers," "For Students," and "For the Public." Curriculum supplements and educational resources are identified. "Science in the Cinema" is particularly interesting. Six movies with high scientific content and available as videos are reviewed with the science in each discussed. There are also some extensive download files (40 Mbytes) on topics such as the Brain. A CD is available. Although directed towards high school age students, everyone can benefit from materials found at this excellent Web site.

These sites were checked September 13, 1999. Previous ASCB columns reviewing Educational web sites with the links to the sites may be found at trinity.edu
