From ASCB President Elaine Fuchs
  10/01/2001

Over the summer, ASCB members were immersed in efforts to urge Congress and President Bush to support the use of federal funds for research on human embryonic stem cells. Many hours were spent with policymakers in Washington, with newscasters and with the public to help to address important scientific and ethical questions surrounding this key research. When President Bush announced on August 9 that he would allow NIH funds to be used in support of research on approximately 60 existing human embryonic stem cell lines, cell biologists immediately focused on new questions: where are these 60 lines and how accessible will they be to research scientists? How stable and pluripotent will these lines be over long-term passage? How many of these 60 lines will be useful in the quest to ascertain the properties of human embryonic stem cells and to assess their potential therapeutic use for the treatment of a host of human disorders? If a discovery is made, who owns the rights to this discovery, and more importantly, will such legal issues impede the speed with which discoveries can be translated into therapies for patients who suffer from devastating degenerative disorders? How many scientists in the US will move to England and other countries where the limitations on human embryonic stem cell research are not so constraining? Will the constraints placed on human embryonic stem cell research enable the United States to maintain its position at the forefront of biomedical research in the world?

Throughout August and into early September, these important questions were oft discussed by ASCB members, the public, the news media and the government, as universities, scientists, biotechnology companies and the government grappled with the implications of President Bush’s declaration on stem cell research in the US.

On September 11, 2001, the focus on human embryonic stem cell research came to a sudden halt as the United States and the world were shocked and horrified by the disasters that struck in New York City, Washington, DC and rural Pennsylvania. These tragic events leading to the ghastly deaths of nearly 7,000 individuals have now changed how we view our priorities and how we run our daily lives. Life as we know it will never be the same, and our sense of security and peace within the world has been seriously shaken. Weeks later, as we struggle to return to a modicum of normalcy in our lives, we find ourselves calling for an end to hatred in the world, something so easily said and yet so difficult to attain. The anger aroused in the world is smoldering, long past the devastation to buildings and human lives. Ironically at a time when Americans have joined together in beautiful triumph and harmony to help those who have lost buildings, businesses and loved ones, suspicion and mistrust throughout our country is at an all time high. Ethnic and religious differences have received the brunt of these ill feelings, and such ill feelings have bred further ill feelings throughout the world. We find ourselves grappling with our own feelings and trying to understand how a small number of people in the world could hate so severely that they would wreak this kind of havoc and destruction.

As scientists, we have all been taught the importance of reason. Renewed again in our guiding convictions, we can help demonstrate how reason can influence human affairs for the good. As we return to our research, our labs, our science and our education, we hope that terrorism will not be combated by isolated countries or groups nor with hatred to selected countries or religions, but rather by a world unified in its collective stance against terrorism as an entity that damages and endangers us all.

Late Career Opportunities for Cell Biologists
  10/01/2001

Work-related opportunities that are available for cell biologists late in their careers will be featured at a special forum sponsored by the ASCB Education Committee on Tueday, December 11 at the ASCB Annual Meeting. Dick McIntosh, Professor of Cell Biology from the University of Colorado, will chair the session to include brief presentations of experiences and professional work with late-career issues.

Retiring from a job that has served as the focus of one’s professional life raises serious issues. Scientifically, many researchers cherish the hope that each new year will be the best ever. Personally, scientists are often fortunate enough to enjoy their work, so stopping feels like a loss. Some are concerned about financial security, given that one cannot know future rates of inflation, and the costs of old age can be horrific. Since Congress eliminated mandatory retirement, the decision to step down has become more personal than in times past, a situation that has major implications for both the individual and the profession.

Some believe that virtually all scientists have worked hard, so their institutions should continue to employ them for as long as they want to work. In a simple sense this is the law, and for some people, even discussing retirement can feel like an infringement of right. Joel Rosenbaum from Yale will present the point of view that cell biologists should be able to continue in their jobs as long as they want to work.

Some senior scientists hold that retirement is an amazing opportunity for creative and novel action. There may be a sacrifice of income and power, but one acquires a freedom of behavior and choice that has been hard to find for 30 years and more. This occasion can be used to undertake something really new and interesting: a different teaching challenge, a novel research environment, a totally different kind of research, or an advisory post that allows one to share experience and hard-won wisdom. Bob DeHaan will describe his work with the public school system in Atlanta, where he has been working to help bring innovative science pedagogy to K–12 classrooms. Dick McIntosh will describe the research project he is developing with a colleague in Uganda.

Others argue that a scientist’s creativity and productivity drop with the years, while salary does not. Add to this that the median age of life scientists has been going up at a rate of almost one year per year for the past 20, and it would seem that the aging population presents a serious challenge to the institutions that support science. Marvin Cassman, Director of the NIH NIGMS, will discuss research funding profiles for older scientists and about the diversity of opportunities available to active but not-currently funded scientists.

Estelle Fishbein, Vice President of the Johns Hopkins University, will present information about retirement as a senior university administrator who is thoroughly knowledgeable about TIAA/CREF and other practical matters relating to retirement.

Organizers hope that other senior scientists will contribute their own relevant experience from the floor, so everyone can pool knowledge and ideas about opportunities for late career activities that can be rewarding and valuable. Clearly, many of the views mentioned above are not mutually exclusive, and there is much room for discussion about how one might best consider their own retirement so as to make the latter career one of the best parts of a scientist’s working years.

The panel will be held on Tuesday, December 11, at 1:30 p.m. in Room 30 of the Washington Convention Center.

Science Education: A Priority for the Nation and for ASCB Members
  10/01/2001

We’ve all heard that America’s K-12 students are no longer performing as well in science as their peers in many countries throughout Europe, Asia and Australia. Most importantly, the passion for biology often wanes during K-12 schooling, and yet there is so much excitement in biology these days, and biology is so much at the forefront of our daily lives. How can this happen?

All of us have been concerned, as dwindling interest and achievement in science during the K-12 years ultimately impacts on the future of the cell biology community. Many of our ASCB members have gotten involved in K-12 science education and have made concerted efforts to establish and/or participate in programs that interface our cell biology community with teachers and students in grade schools, middle schools and high schools across the country. These participatants include a broad spectrum of our ASCB members, including graduate students, postdoctorates, college teachers, faculty members and research scientists. For some of you, these rewarding experiences have translated into an alternative career in K12 science education efforts. For others, they have provided you with valuable experience and new perspectives to bring towards teaching and communicating at higher educational levels. For still others, these experiences have been just plain pleasurable and gratifying.

For those of you who have been involved in various K-12 programs, would you like to share and exchange experiences with other ASCB members? What about those of you who have never been involved in K-12 education? Would you like to hear from your peers who have done so? Would you like to know more about these experiences, and how you might get involved?

Whether you are interested in getting involved in a small way or a big way, or whether you’d just like to find out more about the opportunities for linking cell biologists to K-12 science education in your own community/ University, please sign up and plan to attend the Special Symposium Luncheon on K-12 Education at our Annual American Society for Cell Biology Meeting on Tuesday, December 11. The Symposium, entitled “Educating Our Future Cell Biologists” will feature talks from Bruce Alberts, President of the National Academy of Sciences and Maxine Singer, President of the Carnegie Institution of Washington. Both of these internationally recognized leaders within our Society have willingly devoted large amounts of their time and effort towards improving the ties between K12 schools and the scientific research community. Their talks will be followed by round table discussions on topics ranging from graduate student/postdoc volunteer teaching programs at local K-12 schools, to setting up, running or participating in programs to enhance K-12 student and teacher education in cell biology. For this special session, the Education Committee is presently compiling a state-by-state listing of as many of the existing K-12/Science Programs as possible, so that if you are inspired to become involved, you will be able to do so following the Lunch.

So come to the Lunch and take advantage of this special opportunity provided to you at this year’s Annual Meeting. If you did not preregister you may sign up at the Event Tickets Counter in the registration area of the Washington Convention Center starting on Saturday, December 8. It is your chance to learn more about this important endeavor and to find out how you can enrich your career by getting involved in a most rewarding venture.

—Elaine Fuchs President, The American Society for Cell Biology

The following member-organized sessions were selected by the ASCB Program Committee for presentation before the opening of the ASCB 41st Annual Meeting in Washington, DC. All Annual Meeting attendees are welcome to participate; no separate registration is required.

A. Bone Cell Biology
Room 12
Organizer: Masaki Noda, Tokyo Medical and Dental University

Bone cell biology has been advanced greatly in the area of attachment molecules and their cognate receptors, extracellular matrix protein and regulation of intracellular signalings. Advances in the cell and molecular biology of osteoblasts and osteoclasts are at the depth of science, which is contributing the medical science to treat patients with bone diseases such as osteoporosis and osteoarthritis. This subgroup meeting is proposed to put together the topics in the field of bone biology to discuss and exchange information.

Speakers:
Steve Teitelbaum, Washington University School of Medicine
Gary Stein, University of Massachusetts Medical School
Nicky Partridge, UMNDNJ
Benoit deCrombrugghe, University of Texas/MD Anderson Cancer Center
Masaki Noda, Tokyo Medical and Dental University

B. Building the Cell
Room 25
Organizer: Wallace Marshall, Yale University

Modern cell biology has made great strides in understanding cell structure and function. As with any engineering problem, however, there is a third important aspect that needs to be understood besides structure and function, and that is assembly. How are the complex structures found within the cell specified? As we enter the post-genomic era, the mechanisms that determine the position, number, size, and shape of organelles remain virtually unknown. The goal of this session is to bring together researchers, working in different fields of cell biology, who share a common interest in these long standing but unanswered questions. By discussing and comparing recent results from different systems, we hope to stimulate further explorations into the mechanisms of cell morphogenesis.

Speakers:
Velia Fowler, Scripps Research Inst. Length determination in muscle actin filaments.
Wallace Marshall, Yale University. Length determination in flagella.
Lewis Tilney, University of Pennsylvania. Length determination in bristles.

Present in virtually all cell types in animals ranging from cnidarians to man, 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 have been linked to several human diseases. This session, the 9th consecutive meeting for this well-attended subgroup at ASCB, will address new developments in our understanding of gap junction diversity, assembly, regulation, channel structure/function, and role in physiological processes.

Speakers:
Viviana Berthoud, University of Chicago School of Medicine. Impaired trafficking and loss of function in a cataract-associated mutant connexin50.
Sandra Murray, University of Pittsburgh School of Medicine. Imaging of gap junction protein trafficking.

Gary Goldberg, State University of New York at Stony Brook. Normalization of tumor cell growth by intercellular communication
Kris Spaeth, State University of New York at Buffalo. Hemichannels of several connexins have distinct permeabilities from their intercellular channels, and are regulated by intercellular coupling in oocytes

D. Dynamics of Nuclear Structure and Function
Room 37
Organizers: Robert D. Goldman, Northwestern University Medical School and Thoru Pederson, University of Massachusetts Medical School

This session will feature very recent studies that provide new insights into the functional dynamics of the nucleus. The talks will emphasize work carried out in living cells, and several of the presentations will report novel and surprising findings, including unanticipated interactions among nuclear components. Moreover, several of the talks will have a very high degree of disease relevance.

Jan Ellenberg, European Molecular Biology Laboratory. The mechanisms of nuclear envelope breakdown studied in living cells.
Robert Goldman, Northwestern University Medical School. Nuclear lamins: their roles in nuclear shape, assembly and transcription.
Kathy Wilson, Johns Hopkins University School of Medicine. Chromatin attachment to the nuclear membrane and lamina.
Howard Worman, Columbia University College of Physicians & Surgeons. Inner nuclear membrane proteins, nuclear function and human disease.
Brian Burke, University of Calgary. Nuclear lamin defects and their links to human disease.
Warner Greene, University of California, San Francisco. HIV-1 Vpr induces dynamic disruptions in nuclear architecture and integrity.

E. Integrated Approaches to Cell Architecture and Dynamics
Room 13
Organizers: Jeffrey Nickerson, University of Massachusetts Medical School and Michael Mancini, Baylor College of Medicine.

The deluge of genome sequence, to be followed by a complete specification of the proteome, will provide a protein inventory for cells and some hints as to their individual functions. An inventory, however, can only be first step in understanding cells, tissues and organisms. The organizing principle that will integrate this flood of information is structure, the same principle that organizes individual proteins into assemblies, organelles and cells. In this symposium we will take an integrated approach to cell structure—not dividing it into cytoskeleton, nuclear matrix, mitotic architecture, or ECM, but exploring the common themes that are emerging from all of these separate interest groups.

Speakers:
Sui Huang and Donald Ingber, Harvard Medical School. Cell fate control by cell shape: towards an integrated, genome-wide view of regulatory pathways
Mark Ellisman, UCSD. Dynamics of gap junctions and their proteins studied with a new method for correlated light and electron microscopy
Peter Cook, University of Oxford. Nuclear protein synthesis at sites of polymerase II transcription
Alan Herbert, Boston University. Regulated protein synthesis in the nucleus
Kip Sluder, University of Massachusetts Medical School. Centrosomes and the cell cycle
Dereck Radisky and Mina Bissell, Lawrence Berkeley Laboratory.
Michael A. Mancini, Baylor College of Medicine. Subnuclear dynamics, transcription factor function and nuclear structure
Jeffrey Nickerson, University of Massachusetts Medical School. The dynamic architecture of RNA processing and nuclear export

F. Mechanical Load Responses of Cells in 3D Cultures
Room 35
Organizer: Albert J. Banes

The subgroup meeting will focus on three-dimensional culture models, cell responses to 3-D versus 2-D environments and mechanical loading models of 3-D cell-populated gels.

G. Microtubule Plus-End-Tracking-Proteins
Room 14
Organizer: Holly Goodson, University of Notre Dame

Microtubule plus ends have long been a site of interest because the specific conformation of tubulin at the plus ends is thought to regulate microtubule dynamics. Until recently, only one protein, CLIP-170, was known to associate with these plus ends. However, it is becoming apparent that the microtubule plus end is a crowded place—an ever increasing set of evolutionarily conserved proteins, including dynactin complex, LISI, TOGp, EB1, and APC have been found specifically or predominantly at microtubule plus ends. Live GFP-imaging experiments have demonstrated that many/all of these proteins dynamically “track” the growing tip. These proteins have been implicated as key components of processes ranging from membrane transport to cell polarity in systems ranging from humans to yeast. What is the functional significance of this common localization to MT plus ends? Do these proteins interact in shared pathways or merely colocalize while acting independently? By what (interdependent?) mechanisms is this localization achieved? What is the significance of these proteins for control of microtubule dynamics and its role in morphological change? The talks in the Special Interest Subgroup meeting will address these issues and attempt to integrate this information into a coherent model for function of proteins at microtubule plus ends.

Speakers
David Pellman, Dana-Farber
Jennifer Tirnauer, Harvard
Richard Vallee, University of Massachusetts, Amherst
Kevin Vaughan, Notre Dame
Holly Goodson, Notre Dame
Lee Ligon, University of Pennsylvania
Ewan Morrison, University of Leeds

H. Multidisciplinary Integration in Cell Biology
Room 27
Organizer: H. Steven Wiley, Pacific Northwest National Laboratory

Cell biology has traditionally been one of the most technologically diverse fields in biology. Understanding cell function requires an analysis of molecular to cellular processes occurring in time frames from microseconds to days. The challenges of these dynamic ranges have been met by applying a remarkable range of technologies from electron microscopy and molecular biology to live cell imaging and computer simulations. The evolution of these powerful technologies has created an additional hurdle of date analysis and assimilation. The greatest technical challenge in the next decade will be integrating the expanding mass of diverse biological date into a system-level understanding of cell function. The aim of this Special Interest Subgroup meeting is to bring together investigators using a variety of new high-throughput technologies and those interested in integrating this information into realistic models of cell function. The challenge is to design instrumentation and data analysis technologies that can provide the quantitative data necessary for modeling of biological systems. The models, in turn, must be accessible by biologists and must generate predictions that can be experimentally tested. Connecting experiments to computer-based models is a potentially powerful way to approach complex systems, but how to achieve this integration is currently unsolved.

Speakers:
James Bassingthwaighte, University of Washington
Scott Fraser, Cal Tech
Douglas Lauffenburger, MIT
Fred Maxfield, Cornell University
H. Steven Wiley, Pacific Northwest National Laboratory

I. Myofibrillogenesis
Room 15
Organizer: Joseph W. Sanger, University of Pennsylvania School of Medicine

Central to the form and function of muscle are the myofibrils, membranous components and the cytoskeleton that provide the structure, the contractile force and regulation. The challenges of identifying the essential steps involved in these processes and understanding how the myofibrillogenesis is initiated and controlled are still unmet. This session will present several short presentations on the latest advances in the study of myofibrillogenesis.

J. Primary and Sensory Cilia
Room 23
Organizers: Joel Rosenbaum, Yale University, and George Witman, University of Massachusetts Medical School

Primary cilia are non-motile cilia that occur singly on most cells in the vertebrate body. Previously, nothing was known about their function. Interest in primary cilia and sensory cilia, which develop from primary cilia, is rapidly increasing due to their involvement with human diseases, including developmental disorders, polycystic kidney disease, and degenerative diseases of the retina. Intraflagellar transport (IFT) functions in these cilia, and provides one avenue for learning more about their assembly and function. Talks will provide overviews of important new advances in understanding and manipulating these ubiquitous cell organelles.

Speakers:
Jonathan Scholey, University of California, Davis
Maureen Barr, University of Wisconsin, Madison
Gregory Pazour, University of Massachusetts Medical School

K Quantitive Microscopy & Image Informatics
Room 30
Organizer: Peter Sorger, MIT, Jason Swedlow, Wellcome Institute, Dundee, and Gaudenz Danuser, ETH Zurich

This subgroup will cover new developments in the quantitative analysis of images from optical microscopes. It will have a particular focus in the emerging area of image informatics, the large-scale analysis of images using database-driven computational methods. Talks will cover multidimensional microscopy, image databases and three-tier computational architectures, chemical genetics and screening by imaging as well as several examples of heuristic image analysis in yeast and animal cells. Talks will focus on concepts in image informatics and the application of quantitative microscopy to molecular cell biology rather than on technology and methods per se. Thus, the program is expected to have broad appeal to cell biologists particularly those with an interest in engineering, computation and chemistry.

L. Role of MAGUKs and PDZ Proteins in the Assembly and Regulation of Cell-Cell Junction
Room 3
Organizer: Alan S. Fanning, Yale School of Medicine

The Membrane-Associated Guanylate Kinase (MAGUK) homologues comprise a family of membrane-associated scaffolding proteins that regulate the assembly and function of specialized membrane domains; including adherens junctions, tight junctions, and neuronal or immune synapses. This special interest subgroup will focus on the different mechanisms that are utilized by MAGUKs and other PDZ proteins to assemble protein complexes at cell-cell contacts in vertebrates and invertebrates using experimental methods of cell biology and genetics. It will focus on how MAGUK and other PDZ proteins organize proteins at the plasma membrane and link them to cytosolic signaling proteins and the cytoskeleton. It will also examine the emerging role of these proteins in the trafficking of junctional components to specific subcellular locations and the organization of cell polarity. Finally, special emphasis will be placed on the emerging paradigm that intramolecular interactions within the MAGUK proteins act as “molecular switches” which regulate the assembly of different polypeptides into the MAGUK/PDZ scaffold.

M. Septin Structure and Function
Room 10
Organizers: Christine M. Field, Harvard Medical School and John Pringle, University of North Carolina at Chapel Hill

Septins are a family of conserved proteins that have been implicated in a variety of cellular functions involving specialized regions of the cell cortex, such as cytokinesis, cell shape change, and vesicle fusion. Septins form heteromeric complexes that bind and hydrolyze GTP, polymerize in vitro, form neck filaments in vivo (yeast), and bind phophoinositide lipids. Septins are implicated in regulating contractility, exocytosis, membrane compartmentation, and apoptosis, but their precise molecular functions are not known, and there are many basic questions to explore. This session brings together researchers working on a variety of systems to discuss progress in understanding molecular architecture, biochemical activities, and cellular functions known, and there are many basic questions to explore.

N. Urothelial Cell Biology
Room 11
Organizers: Ricardo Saban, Oklahoma University Health Science Center, and Timothy G. Hammond, Tulane Medical School.

The urothelium, the epithelium lining the surface of the urinary bladder, is a unique cell type with high plasticity and a variety of cell functions. Urothelium represents the first line of bladder defense and an interface between pathogens and defense mechanisms. Functions of the urothelium include control of permeability and immune responses. Cell-cell communication seems to play a major role on urothelial cell response to injury and infection. This response is modulated by Nerve and EGF-like Growth Factors. In addition, despite the fact that urothelium is a frequent site of cancer formation, few experimental model systems are currently available or well characterized for studying urothelial cancer. The identification of uroplakin genes that are specifically expressed in the urothelium has made it possible to target unique oncogenic events to the in vivo urothelium and to evaluate their biological potential in inducing urothelial transformation and tumorigenesis. This meeting will have an emphasis on cell-cell communication as well as the urothelium as the first line of defense. We have included some of the lead researchers and techniques in the field that will present new animal models and the molecular basis of infection and inflammation.

WWW.Cell Biology Education
  10/01/2001

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. Advanced Molecular Biology Techniques Laboratory
    Beverly Clendening of Hofstra University brings us this very useful site. As part of an NSF-DUE-CCLI grant, this site gives as its purpose: ”This advanced molecular biology laboratory course, which uses a project approach to learning and incorporates an independent research component, was designed to enhance the preparation of students for careers in research, biotechnology and science education and to increase knowledge retention and integration of concepts among upper level biology majors.” The Drosophila-based labs are navigated by seven routes. The Introduction provides students with an overview of the course design and provides basic information about Enhancer Trap Analysis. The Protocols section provides general instructions for agarose gel electrophoresis, optical density measurements, DNA precipitation, enzyme use, and UV spectrophotometry. Also included under the Protocols section are 23 lab exercises including the following: plasmid rescue, competent cell preparation, ligation, transformation, PCR splicing, sequencing, Southern, Northern, and labeling, hybridization, and detection of DNA probes. Each of the protocols is clearly laid out and in some cases have hot links to other sections. A Sample Results section provides a pictorial guide of what should be seen as one carries out the procedures. A Tutorials area provides instruction in “Creation of the P-element insertion line, Jump-out and Jump-start mutagenesis, and genetic mapping of mutants. If one is looking for ideas for setting up an advanced molecular biology course, this is a very good place to begin. Thanks to ASCB member Dorothy Pumo for calling attention to this new educational URL
  2. The Virtual Reference Desk
    This site is sponsored by the U.S. Department of Education. The homepage states: “The Virtual Reference Desk (VRD) is a project dedicated to the advancement of digital reference and the successful creation and operation of humanmediated, Internet-based information services.” Of particular use is the AskA service. A number of professional organizations maintain Internet help services for students and teachers. The premise of these services is ask a professional a question andget an answer over the Web. VRD provides a descriptive list ofthese services and the links to reach them. Everything from Art and Careers to Math and Philosophy have AskA services. One might be surprised at how many professionals are participating in these types of programs. Sixteen sites are listed for biology. Other resources are identified at this site that have high utility. You might want to spend some time here and see what is available.
  3. Hypertextbook: Cell Biology
    This site serves to support the introductory biology course at MIT. The first URL listed above is for the cell biology chapter and the second for the whole textbook. The cell biology chapter is divided into 13 sections. The material for membrane proteins, receptors, and transport mechanisms would aid many college level courses. AP biology students would appreciate the material as well. Illustrations and hot words are incorporated into the primarily text-based information. There is a section for Cell Biology practice problems that is quite useful. If you want to see clear, well-identified support material for basic cell biology course, this is a good place to go.
  4. Human Genome Symposium Webcast
    On August 25, 2001 a symposium was held at UC Santa Cruz on the human genome. Francis Collins gave a historical overview of the human genome project and talked about the hidden features in the cover of the Nature magazine announcement of the genome project published in Feb. of 2000. Richard Harris presided over a panel consisting of Francis Collins, Robert Sinsheimer, Gene Myers, and Mary-Claire King. By logging on to the URL you can attend over two hours of the conference on the Web. It would be a great way to introduce a class discussion on the human genome by letting students see and hear major players in the project.

These sites were checked September 20, 2001. Previous ASCB columns reviewing Educational Websites with the links to the sites may be found online.
