100, 100: Genetically Engineered Human Insulin Created

Humulin R Box and Vial

In honor of the 100th anniversary of the first administration of insulin, JDRF launched “100 Years, 100 JDRF Scientists,” to tell the story of scientists and their discoveries, putting together the vast knowledge that we have about diabetes today.

The next one: Genetically engineered human insulin.

Before the advent of human insulin, insulins were derived from animals, and safe dosing was wildly inconsistent. But in 1976, research teams set out to synthesize the human insulin gene and make human insulin, and JDRF researchers had multiple hands in the biosynthesis of it.

It all began when Eli Lilly called a meeting on May 24-25, 1976. Presenting first was William L. Chick, M.D., a junior faculty member at Joslin Diabetes Center, who had recently developed a rat with a rare tumor in beta cells—called insulinoma—which could generate huge amounts of insulin [1]. He had a JDRF grant beginning in 1976.

Several of the teams at the Lilly meeting were planning on isolating the human gene for insulin and cloning it, and Chick’s insulinoma model provided the raw material. From the insulin gene to the cloning of it; this is where it all began.

The City of Hope-Genentech team prevailed in the summer of 1978 [2]—for which we gave the David Rumbough Award in 1979 to Arthur Riggs, Ph.D., David Goeddel, Ph.D., Keiichi Itakura, Ph.D., Roberto Crea, Ph.D., and Dennis Kleid, Ph.D.—however, there were two more groups involved:

In October 1982, the FDA approved the first genetically engineered drug, Humulin®, and would go on to approve many more insulins—short- and rapid-acting, long-acting, and a nasal version of it.

There are now genetically engineered therapies not just for diabetes, but for cancer, hepatitis B, stroke, and others. Research is how genetic engineering made the first human insulin product, and JDRF research is advancing us toward cures and the next generation of life-changing breakthroughs for T1D.

Follow up each week to find out who we selected and their major discoveries, in honor of the 100th anniversary of the first administration of insulin.

*I thank—very much so—the book by Stephen S. Hall, Invisible Frontiers: The Race to Synthesize a Human Gene (1987), who captured the turns and tribulations of the race to clone the human insulin gene and, with it, the birth of biotechnology.
