Book Description
Simian virus 40 gained notoriety in the 1960s because it was found to be a contaminant of polio and adenovirus vaccines that had been administered to millions of healthy individuals worldwide. The public health implications of this revelation provided the initial impetus for an in-depth study of SV40 biology. Later work showed that SV40 DNA sequences as well as infectious virus are in fact found in human tumors and may have contributed to oncog- esis. It also turned out that SV40 uses mostly cellular machinery to carry out many steps in viral infection, which makes it a powerful probe for examining many fundamental questions in eukaryotic molecular biology. SV40 Pro- cols consolidates a number of well-tested step-by-step techniques in one v- ume; experts with hands-on experience in particular methods give detailed accounts of their optimized experimental protocols, so that the beginner, as well as more experienced researchers, may readily overcome problems of ambiguity often present in the literature. As with other DNA tumor viruses, the response of cultured cells to SV40 infection depends upon the species being infected. Monkey cells s- port virus production, which leads to their death, whereas rodent cells p- duce only the early proteins and acquire a transformed phenotype. Thus, SV40 Protocols is organized in two sections. The first relates to assays of the lytic cycle of the virus, and the second deals with transformation.

Book Description
A. Definitions of Transformation in vitro When normal tissues or organs are explanted to conditions favoring the growth of cells as individual units ("cell culture"), the original cell population undergoes a large variety of modifications. Only a minority of the cells will thrive and multiply and within a rather short period of time, the complex composition of the original explant is replaced by a much simplified one of only a few recogniz ably different cell types. With most organs fibroblast-like cells survive longest and outgrow other types. This is then a stable state of affairs for many gener ations. This treatise will not discuss whether this simplification and stabilization represents selection of certain pre-existing cell types or a modification of cells into only a few recognizably different categories; for an excellent review see HARRIS. (1964). Table 1. Terminology Employed to Describe Transformations in vitro Type of transformation Essential features Irregular growth Lack of contact inhibition of cell membrane movement ("ruffled membranes") between juxtaposed cells Unrestrained growth Deficient inhibition of the cell cycle (mitosis) in a crowded culture Infinite growth Capacity of cells to undergo an infinite number of di visions (formation of established cell lines) Cells may depart from this typical behavior in numerous ways involving for instance cellular morphology, immunology, chromosomes or metabolism. Such changes have, sometimes rather vaguely, been called "transformations". This is unprecise and the term "transformation" will here be used exclusively to indicate disturbances in cell growth related to neoplasia.

Book Description
This unique book focuses on the DNA viruses in the human population that are associated with cancers. It covers most of the viruses that are thought to contribute to human malignancy. This book represents a comprehensive review of the field of DNA tumor virology. Right now, while there are books out there that cover individual viruses that are also covered in this book, there is no single book that covers this topic comprehensively. This book is the first current, comprehensive review of its kind in the market.

Book Description
The Immunization Safety Review Committee was established by the Institute of Medicine (IOM) to evaluate the evidence on possible causal associations between immunizations and certain adverse outcomes, and to then present conclusions and recommendations. The committee's mandate also includes assessing the broader societal significance of these immunization safety issues. While all the committee members share the view that immunization is generally beneficial, none of them has a vested interest in the specific immunization safety issues that come before the group. The committee reviews three immunization safety review topics each year, addressing each one at a time. In this fifth report in a series, the committee examines the hypothesis that exposure to polio vaccine contaminated with simian virus 40 (SV40), a virus that causes inapparent infection in some monkeys, can cause certain types of cancer.

Book Description
The position of "Cancer Teaching Coordinator" at The University of Chicago has been a consistently rewarding one because of the enthusiasm and support of the faculty and the students. This volume is the result of the second of two recent intensive teach ing sessions which have been planned and implemented by the group which forms the Cancer Coordinator's Advisory Committee. The first of these teaching sessions was held in early March of 1964 and was entitled "LEUKEMIA, A Current and Forward Look. " It attracted overflow attendance from the students and staff of this medical institution augmented by members of the other medical centers in Chicago. It was a stimulating and instructive colloquium, and the only regret we heard expressed afterward was that we had not arranged for publication of the many excellent presentations. One of the events commemorating the seventy-fifth anniversary of the founding of The University of Chicago was this symposium on malignant transformations. This time the Committee advised us to plan on speedy publication, and, logically, it chose Dr. Werner Kirsten, a member of our faculty and an active and effective investigator in this general field of endeavor, to serve as editor of the volume. Again, two of the same ingredients for effective instruction were blended: an excellent group of scientists presenting their latest work and a fine, attentive audience of students and staff.
