501 STATEMENT OF LEON 0. JACOBSON 19 I am Leon Orris Jacobson from The University of Chicago in Chicago where I continue as a physician-scientist emeritus and have served as Chairman of Medicine, Dean of `fedicine 3n3 Biology and Director of the Argonne Cancer Research Hospital. In February 1942 I became responsible for the medical safety of the personnel of the Metallurgical Laboratory (the atomic bomb project) under the direction of Arthur Obmpton, Norman Hillherry, Enrico Fermi, Leon Szilard and many others who achieved the first self-sustaining chain reaction. Iater I served as Associate Director and then Director of Medicine and biology of this enormously successful national program that brought the war abruotly to an end and in the aftermath provided the tectnology and the radioisotope tracers so enormously important to the revolutionary advances in biologv and medicine that contribute an ever increasing momentum to cur un3erstan3ing of normal as well as disease processes. I joined the Scientific Advisory Board of the Tobacco Industry Research Committee (now called the Council for Tobacco Research - U.S.A. , Inc. ) in 1954 when it was under the leadership of Clarence Cook Little. Dr. Little aooeared before (bngressional committees dealing with smoking an3 health in 1955 and 1969. The mandate of the Scientific Advisory 9oar3 was broad 3nd simple, namely to sponsor independent research in
Page 2: ukv99d00
502 the area of tobacco and health. The Scientific Advisory Board ras and is today composed of individual scientists whose expertise covers those disciplines of the biomedical sciences that are essential to understanding the complexities of chronic diseases and their pathogenesis. In spite of the successful elimination of many diseises caused by infectious agents, we are still groping for an unierstanding of th e inexorabl e proces s o f chroni c d iseases such as arteriosclerosis and cancer. Are we in any better position today to fathom the challenging puzzle of caise and cure of these devastating medical problems? ae are becoming more aware of the fact that cancer, arteriosclerosis, and other chronic diseases are not the result of exposure to a single substance that has been inhaled or eaten. For example, arteriosclerosis is hastened by a concomitant hypertension, but occurs even in peoole who are of normal weight and without hypertension. What causes the arteriosclerosis that leads to coronary occlusions and strokes? Here we have a controversy that will be resolved only when each of the categories of research unravels the cascade of events that leads to death or disability. It would be disastrous, for example, to decide now that arteriosclerosis is primarily a problem relating to blood lipi3 control. Cancer etiology and control have been intensively researched, especially in the past 75 years. We have learned much from the rapidly developing area of molecular biology - 2- 503 which is driving us nearer and nearer understanding the thousand and one cor membranes, within cells and in organs required for maintaining the normal s' beginning to understand the interrela cells, tissues and organs such as the adrenals as well as the brain itself. constituents is not an independently f rather part o f a wonderful organism wc I healthy individual which quite often r abnormalities (or copying mistakes) t} `_rorc injury or disease.

which is driving us nearer and nearer to the ultimate goal of understanding the thousand and one continuous reactions in cell membranes, within cells and in organs and tissues that are required for maintaining the normal steady state. We are just beginning to understand the interrelationships of individual cells, tissues and organs such as the lung, kidney, and adrenals as well as the brain itself. Each of these body constituents is not an independently functioning entity, but rather part of a wonderful organism working in harmony in the healthy individual which quite often reverses or corrects abnormalities (or copying mistakes) that result spontanously or from injury or disease. Soontaneous mistakes in the process of cell division are inevitable because millions of cells must yield exact copies of the genetic information they possess to their progeny. The body has the ability to reoair the strands of genetic material in which a mistake occurred in the reproduction process. If the reoair is incomplete or fails then the newly formed cell might die or it may go on to develop a new kind of cell - a cancer cell. Ebw else might cancer occur? We know that selected mice canbe inbred in a deliberate way (by 20 generation crosses) and a predictable percentage of their progeny will develop cancer. This is a very useful laboratory tec`lnique for testing carcinogenicity or cocarcinogenicity of a given chemical or other agent. Likewise, epidemiologists have found and are closely observing human "cancer famil ies" in which the genetic
Page 4: ukv99d00
role is clear. Thus, a full understanding of the complex process of carcinogenesis must consider not only abnormal inherited genes or chemical expceure of the genetic material of a cell but also the possible imaact, involvement or participation of ionizing radiations and ultraviolet rays, viruses and many internal derangements. In the laboratory animal, when studying tucor induction with a given chemical substance or virus, one has better control of the various factors which may play a role in carcinogenesis, but inhumanepidemiological studies it is very difficult to isolate one factor from another. Human beings are exposed to a variety of environmental impingements. They also have d i ffering l i fe s tyles i nvolving v3rious s tres ses, eating habits, drinking or smoking habits, as well as different genetic or constitutional backgrounds. We are seeking ways and there are promising leads in the search for the members o`_ our population who may be susceptible or likely to develop cancer. We have found families with genetically transmitted susceptibility to emphysema. Likewise in the field of cancer, we are now looking for markers to identify peoole who might be susceotible. Whl have I stressed the importance of soontaneous, inherited or induced genetic aberration in the development of disease? SimpLy because many of our dread diseases seem to originate after a lesion occurs in a DNA strand, which may actually lead to the development of an individual cancer or -4 - become an inherited problem in successi example, molecular biology has already 1 sequence in the double helix responsible anemia.

become an inherited problem in successive generations. For example, molecular biology has already located the particular sequence in the double helix responsible for sickle cell anemia. Genetic engineering is a thing of the present that promises rapid progress. Malignant cells carry unique and identifying molecules on their surfaces that are characteristic of the specific malignancy. With current techniques immunologists can develop Killer P lymphocytes that recognize and seek out the specific molecules of malignant cells and destroy the malignancy by attacking the surface molecules of the target malignant ce11s. Many have heard of the hybridoma - a powerful tool that is revolutionizing biology. In the test tube a fusion o f mouse tumor cells and antibody-forming cells results in a hybrid cell that can generate, perhaps immortally, large quantities of antibodies that will react with small pepti3P chains that are a part of a large protein. 'Eaese hybridoma antibodies may also be used to treat tumors. This is an example of what genetic engineering can and is doing. We sha11 see in the next decade, 3n'9, in fact, we are already witness to a wide spectrum of genetic engineering procedures. Even as I stand here at age 70, Z am hopeful that we shall see the answers before the end of this century to many of the diseases that plague us. We are in the mid9le of vast and fruitful fields of moleailar genetics. We can find the genetic 5normalities and we can even solice in new gers segments. We
Page 6: ukv99d00
507 are literally swimming in new knowledge in immunology and only beginning to ap?ly the fruits of these discoveries. This has been a remarkable era of discovery in the area of peptide hormones which exert tremendous influence on many functions, including lung and cardiovascular. The future challenge is to see whether, and how, these peptides say play a role in the causation of chronic disease. From these continuousLy ®erging discoveries, only a few of which I have touched upon today, the synthesis of disparate ` findings occurs. It is this synthesis whichheral3s the understanding of the aging process. Only such understanding will lead to control of our most formidable and complicated diseases such as arteriosclerosis, heart diseases and cancer, as well as the whole category of other degenerative maladies.
