Axel Ullrich

In the early 1990s, Ullrich and his team identified the signaling system involved in regulating tumor angiogenesis, the growth of blood vessels in tumors. He and his team discovered that inhibiting a key player in the signaling system (called vascular endothelial growth factor receptor or VEGFR) suppresses the generation of blood vessels in tumors and slows down cancer cell growth. Years later, a small molecule inhibitor of the VEGFR2 kinase function was developed, from which a derivative was approved in 2006 for the treatment of kidney carcinoma and gastro-intestinal stromal tumors.

The discovery of the drug Sunitinib and clarification of the multi-specific mechanism of action is partly based on discoveries of Axel Ullrich and his team at the Max Planck Institute of Biochemistry in the 1980s in Munich. The discovery, medical and pharmaceutical development as well as clinical testing of the drug was carried out by about 100+ scientists and physicians, at SUGEN, a company co-founded in 1991 by Ullrich, and the Max Planck Society, and other investors.

Ullrich was the first person to clone a human gene, insulin, into E coli. He was one of the first employees of Genetech. While working for Genetech in 1979, he obtained a human insulinoma tissue sample from a surgeon in Munich. The tumor had just been extracted from a woman. Ullrich purified the insulin mRNA from this sample and cloned it into a vector that he inserted into E coli. Thus, he produced a strain of E coli that would manufacture human insulin.

Ullrich received his primary degree in biochemistry at the University of Tübingen, Germany, he received a Ph.D. from the University of Heidelberg in Molecular Genetics in 1975. He did post-doctoral work at the University of California, San Francisco, from 1975 to 1977 and worked as a senior scientist at Genentech in San Francisco from 1978 to 1988. From 1988, he has been at the Max Planck Institute of Biochemistry.

Axel Ullrich (born 19 October 1943) is a German cancer researcher and has been the director of the molecular biology department at the Max Planck Institute of Biochemistry in Martinsried, Germany since 1988. This department's research has primarily focused on signal transduction. Ullrich has received Hamdan Award for Medical Research Excellence, awarded by Sheikh Hamdan bin Rashid Al Maktoum Award for Medical Sciences, Dubai, United Arab Emirates in 2008 and Ullrich and his team received the Wolf Prize in 2010.
