1) A Short History of Biotechnology
While the 1900s will be remembered by industrial
historians as the Information Technology Era and the Physics
Era, the 2000s will most likely be marked as the Biotechnology
Era because rapid advances in biotechnology will completely
revolutionize many aspects of life in coming decades. However,
the field of biotechnology can trace its true birth back to
the dawn of civilization, when early man discovered the ability
to ferment grains to make alcoholic beverages, and learned
of the usefulness of cross-pollinating crops in order to create
new hybrid strains—the earliest form of genetic engineering.
In ancient China, people are thought to have harvested mold
from soybean curd to use as an antibiotic as early as 500
B.C.
Cells were first described as a concept by Robert
Hooke in 1663 A.D., and in the late 1800s, Gregor Mendel conducted
experiments that became the basis of modern theories about
heredity. Alexander Fleming discovered the first commercial
antibiotic, penicillin, in 1928.
The modern, more common concept of “biotech”
could reasonably be said to have its beginnings shortly after
World War II. In 1953, scientists James Watson and Francis
Crick conceived the “double helix” model of DNA,
and thus encouraged a rash of scientists to consider the further
implications of human DNA. The Watson/Crick three-dimensional
model began to unlock the mysteries of heredity and the methods
by which replication of genetic material takes place within
cells.
Significant steps toward biotech drugs occurred
in the early 1970s. In 1973, Dr. Stanley N. Cohen, a Stanford
University genetics professor, and Dr. Herb Boyer, a biochemist,
genetic engineer and educator at UC-San Francisco, introduced
the concept of gene-splicing and created the first form of
recombinant DNA. In 1974, Cesar Milstein and Georges Kohler
created monoclonal antibodies, cells that clone over and over
again to create large quantities of a specific antibody. Many
of today’s top biotech drugs are monoclonal antibodies.
These two discoveries (recombinant DNA and monoclonal antibodies)
created the building blocks of the first modern commercial
biotech drugs.
Boyer and Cohen’s gene-splicing technique
enabled scientists to cut genetic material from the cells
of one organism and paste it into another organism. This was
an important discovery because the genetic material they moved
from one place to another instructs a cell as to how to make
a particular protein. The organism on the receiving end of
the gene-splicing technique is then able to make that protein.
Over time, scientists have perfected the technique of splicing
material that enables cells to create proteins that control
the creation of insulin, the level of blood pressure and many
other human functions. Such genetic engineering enabled, for
the first time, the creation of massive vats of isolated proteins
grown in bacteria or in cells harvested from mammals—in
quantities large enough for the commercial production of new
drugs. (In fact, Boyer and Cohen’s early experiments
involved inserting a gene from an African clawed toad into
bacterial DNA for duplication.)
In 1975 the first human gene was isolated, opening
the door to gene therapy and creating the emphasis that led
to the beginning of the massive, publicly funded Human Genome
Project in 1990. In 1976, Bob Swanson of the now-famous Silicon
Valley venture capital firm of Kleiner Perkins formed a new
business, Genentech, in conjunction with Herb Boyer (see above).
Other early biotech firms arrived soon after, generally funded
by venture capital firms, angel investors and corporate venture
partners (the same triumvirate of funding sources that fueled
the more recent Internet startup boom). These early biotech
startups included many companies that grew into today’s
super-successful biopharma corporations: Amgen, Chiron, Biogen
and Genzyme. The creation of these startups, focused on the
development of new drugs, was particularly noteworthy because
it was the first time in decades that new drug companies were
launched in significant numbers. In fact, most major drug
companies in existence at the beginning of the 1970s could
trace their histories back to the early 1900s or before.
