  • My Name Is Michael Mark Gottesman and My Position Is Deputy Director for Intramural Research at the National Institutes of Health
    NHGRI: OH_Gottesman_Michael_20111113 1 3/1/16 My name is Michael Mark Gottesman and my position is deputy director for intramural research at the National Institutes of Health. I was born on October 7, 1946 in Jersey City, New Jersey. And when I was around two years old, my family moved to Flushing, Queens, and I had most of my formative years growing up in Flushing. I cannot remember a time when I wasn’t interested in science. Probably the first interaction with issues related to public health was as one of many probably millions of children in the United States who got the Salk vaccine as a -- as a test. I remember lining up, they explained to us that this was a trial, and we all got shots, which was not that much fun for a six-year-old or a seven-year-old. And that was a huge sea change. I remember learning about the fact that before then people got polio, kids got polio. They wandered off to camp, they came back paralyzed. And after that period, we didn’t need to worry about polio. So I had the sense that there was a lot that biomedical research could do to alleviate human disease. The next big event scientifically in my life was the launch of Sputnik in 1957, and it was a wake-up call to the United States. We were so-called “falling behind” in the space race, and I was an eleven-year-old boy who was interested in space science. So I spent my childhood after that making rockets, probably not as safely as it should have been, but no unfortunate accidents befell me.

  • Mutation Rates of Escherichia Coli with Different Balanced Growth Rates: a New Fluctuation Test Protocol and Phenotypic Lag Adju
    Mutation rates of Escherichia coli with different balanced growth rates: a new fluctuation test protocol and phenotypic lag adjustments by Christian Terry Henderson Barna A thesis presented to the University of Waterloo in fulfilment of the thesis requirement for the degree of Master of Mathematics in Applied Mathematics Waterloo, Ontario, Canada, 2020 c Christian Terry Henderson Barna 2020 Author's Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Bacteria are the oldest, most abundant life form on the planet, and every other organ- ism's livelihood is dependent on them. The bacteria Escherichia coli (E. coli) is commonly used in microbiology as a model organism to give insight into the functions of bacteria and cells in general. Of particular interest in these studies is the methods with which bacteria grow and evolve. Growth is what propagates a bacteria's species; whereas evolution is what allows them to adapt to the ever-changing world. Evolution is made possible by mutations which change a bacterium's DNA. In 1943, Luria and Delbr¨uck developed a method, called a “fluctuation test", to estimate mutation rates from the number of mutants in a collection of parallel cultures exposed to a selecting agent after growth. The original fluctuation test methodology suffers from two major limitations. First, the bacteria are not in a re- producible, balanced state of growth throughout the test.

    RESEARCH REVIEW INTERNATIONAL MICROBIOLOGY (2006) 9:1–7 www.im.microbios.org Stanley Maloy* The era of microbiology: Moselio Schaechter a Golden Phoenix Center for Microbial Sciences, San Diego State University, San Diego, California, USA Summary. The discoveries over the last decade have demonstrated that micro- biology is a central scientific discipline with practical applications in agriculture, medicine, bioremediation, biotechnology, engineering, and other fields. It is clear that the roles of microbes in nature are so diverse that the process of mining this genetic variation for new applications will continue long into the future. Moreover, the rapid rate of microbial evolution ensures that there will be no permanent solu- tion to agricultural, medical, or environmental problems caused by microbes. These problems will demand a continual stream of creative new approaches that evolve along with the microbes. Thus, the excitement of this field will continue Received 10 January 2006 long into the future.

  • The NIH Human Microbiome Project Authors: the NIH HMP Working Group (
    Downloaded from genome.cshlp.org on October 5, 2021 - Published by Cold Spring Harbor Laboratory Press The NIH Human Microbiome Project Authors: the NIH HMP Working Group (http://nihroadmap.nih.gov/hmp/members.asp) ABSTRACT: The Human Microbiome Project ( HMP), funded as an initiative of the NIH Roadmap for Biomedical Research (http://nihroadmap.nih.gov), is a multi-component community resource. The goals of the HMP are (1) to take advantage of new, high-throughput technologies to characterize the human microbiome more fully by studying samples from multiple body sites from each of at least 250 “normal” volunteers; (2) to determine whether there are associations between changes in the microbiome and health/disease by studying several different medical conditions; and (3) to provide both a standardized data resource and new technological approaches to enable such studies to be undertaken broadly in the scientific community. The ethical, legal, and social implications of such research are being systematically studied as well. The ultimate objective of the HMP is to demonstrate that there are opportunities to improve human health through monitoring or manipulation of the human microbiome. The history and implementation of this new program are described here. INTRODUCTION: It has been known for some time that the human body is inhabited by at least ten times more bacteria than the number of human cells in the body, and that the majority of those bacteria are found in the human gastrointestinal tract (Savage 1977). Throughout the history of microbiology, most human studies have focused on the disease-causing organisms found on or in people; fewer studies have examined the benefits of the resident bacteria.

    Copyright Ó 2009 by the Genetics Society of America DOI: 10.1534/genetics.109.110007 Perspectives Anecdotal, Historical and Critical Commentaries on Genetics Letting Escherichia coli Teach Me About Genome Engineering James A. Shapiro1 Department of Biochemistry and Molecular Biology, University of Chicago, Gordon Center for Integrative Science, Chicago, Illinois 60637 ABSTRACT A career of following unplanned observations has serendipitously led to a deep appreciation of the capacity that bacterial cells have for restructuring their genomes in a biologically responsive manner. Routine characterization of spontaneous mutations in the gal operon guided the discovery that bacteria transpose DNA segments into new genome sites. A failed project to fuse l sequences to a lacZ reporter ultimately made it possible to demonstrate how readily Escherichia coli generated rearrangements necessary for in vivo cloning of chromosomal fragments into phage genomes. Thinking about the molecular mechanism of IS1 and phage Mu-transposition unexpectedly clarified how transposable elements mediate large-scale rearrangements of the bacterial genome. Following up on lab lore about long delays needed to obtain Mu-mediated lacZ protein fusions revealed a striking connection between physiological stress and activation of DNA rearrangement functions. Examining the fate of Mudlac DNA in sectored colonies showed that these same functions are subject to developmental control, like controlling elements in maize. All these experiences confirmed Barbara McClintock’s view that cells frequently respond to stimuli by restructuring their genomes and provided novel insights into the natural genetic engineering processes involved in evolution. HIS article is the reminiscence of a bacterial genet- The worlds of transcriptional regulation beyond simple T icist studying the processes of mutation and DNA repressor–operator models, signal transduction, chro- rearrangements.
