The Other Information Technology
By Bob Gariano
Much has been made of the development of digital information
technology over the last two decades. Cell phones, internet connectivity,
massive centralized data bases, and satellite communications have all changed
our world. During the same twenty years another information technology has
rapidly emerged. It is, if anything, even more complex and revolutionary. It is
molecular rather than electronic and its invention was natural not man-made.
The emergence of genetic engineering and research has revealed a natural system
that sometimes makes our own digital management of information look somewhat primitive.
In the mid 1990s Craig Venter and his team of researchers at
the Institute for Genomic Research completed the first entire genomic
sequencing of a free living organism, the rather mundane microbe known as H. influenzae. This microscopic rod
shaped single cell bacterium was mistakenly considered to be the cause of human
influenza until 1933. A member of Venter’s research team had been studying the genetics
of the organism and it became a natural subject for their enquiry.
In spite of its tiny scale, each H. influenzae was found to have a genome that consisted of almost 2
million base pairs of DNA in a single circular chromosome. This chromosome
contained 1740 protein coding genes, 58 transfer RNA genes, and 18 other RNA
genes. This genome is a complex and comprehensive chemically encoded data base
of information that allows the bacteria to pass on its characteristics to
succeeding generations while adapting to new influences in the environment.
Venter’s team used a sequencing protocol known as whole genome shotgun and the
results of their work were published in Science
in 1995.
The 1990s brought other historic progress in genetic
research, these discoveries occurred in diverse fields. Early in the decade,
the human genome project was initiated to map the entire human genetic code. In
1993 genetically engineered crops were first introduced as commercial products
for agricultural application. Later in the decade, DNA began to have wide
spread use as a tool for criminal investigations. In 1997, the media reported
that the first mammal, Dolly the sheep, had been cloned two years earlier from
a single adult somatic cell at the Roslin Institute in the United Kingdom. It
raised a firestorm of conjecture and debate.
During the late 1990s, medical researchers at Northwestern
University were planning a major genetic research center here in Chicago. The
Center for Genetic Medicine was founded in 2000 and it has emerged as a global
leader in the field. The Center is a collaboration among Northwestern
University, Northwestern Memorial Hospital, and the Lurie Children’s Hospital.
The center includes more than 140 faculty members from 19 university and
hospital departments across these institutions.
Northwestern’s Center for Genetic Medicine is known
throughout the world for innovative and practical research into the fundamental
genetic mechanisms of human disease. For instance, one initiative, the NUgene
Project, has established a collection of genetic and medical records from
20,000 volunteers to provide researchers with a bank of information about
diseases and their genetic causes. Another resource, the Transgenic and Targeted
Mutagenesis Laboratory (TTML) offers services to study the cryo-preservation and recovery of mouse embryos.
The Center for Genetic Medicine is also committed to
improving public understanding of these new technologies. The Silverstein
Lecture Series, made possible by grants from the Herman M. and Bea L.
Silverstein Medical Research Fund for Genetic Medicine, twice a year brings
experts from around the world to speak here on the North Shore. This year, Marc
Williams, the director of the Geisinger Health System Genomic Medicine
Institute, will be at the Northwestern Evanston campus to discuss personal
genome sequencing and how it can change the future of healthcare. Dr. Williams
will speak at 6:00 pm on January 16, 2013 in the McCormick Tribune Center. The
talk is open to the public and is offered without admission charge.
Reservations can be made and more information is available by visiting the
Center’s website at www.cgm.northwsetern.edu .
