Tak Wah Mak, OC OOnt FRS FRSC (麥德華; born October 4, 1946 in China) is a Canadian medical researcher, geneticist, oncologist, and biochemist. He first became widely known for his discovery of the T-cell receptor and pioneering work in the genetics of immunology.[3] He has worked in a variety of areas including biochemistry, immunology, and cancer genetics.

Early life

Born in southern China in 1946 to parents who were silk merchants, and raised in Hong Kong, Mak was not surrounded by scientists while growing up. In fact, he attended a religious school and even contemplated becoming a priest.[4] Although his parents encouraged him to become a doctor, his interests lay elsewhere - in math, biology, and chemistry.[4] Mak and his family moved to the United States of America during the mid-1960s and with the choice of going to the University of California or Wisconsin, he was persuaded by his mother to attend Wisconsin to avoid the antiwar activities at California. His interest in life and chemistry led him to eventually studying biochemistry and biophysics at the University of Wisconsin.

University Life

At the University of Wisconsin, Mak met virologist Roland Rueckert.[4] Mak initially went to his lab to inquire about a job posting from Rueckert's lab looking for someone to wash test tubes.[4] After his first day on the job, Mak asked if more cleaning work was available, in which Rueckert said there was not, however there was experimental research work available. That, as Mak would later state, would be the beginning of his scientific career.[4] After finishing his degree at Wisconsin, Mak moved to Canada to begin his doctoral studies at the University of Alberta, Edmonton. In the early 1970s, he earned his PhD in biochemistry from the University of Alberta. After he obtained his degree, Mak moved to Toronto and became a Canadian citizen. In Toronto, he worked with Ernest McCulloch and James Till, who discovered haematopoietic stem cells.

Scientific career

In 1980, Mak returned to Wisconsin to learn new techniques in the lab of Howard Martin Temin, who would later win the Nobel prize in Physiology or Medicine for his discovery of the enzyme reverse transcriptase.[4] Temin would be one of his mentors that shaped his way of thinking, encouraging him to delve into diverse disciplines. During the early 1980s in Toronto, with his newly setup group, Mak was working on virology. Mak employed a technique called molecular subtraction, used by virologists, to attempt to identify the T-cell receptor, which was so elusive at the time it was referred to as the "Holy Grail of Immunology".[5] In 1984, Mak discovered the T-cell receptor, with Mark Davis identifying the receptor in mouse.[6] This work on the cloning of T-cell receptor genes, as of 2005, has been cited nearly 1200 times. In spite of offers from prestigious institutions around the world, Mak remained committed to Canada’s scientific community.

In 1993, Mak received support from the world's largest independent biotech company, Amgen, to establish the Amgen Research Institute in Toronto. Financial support from Amgen resulted in his lab pioneering the use of knockout mice,[7] and as a result his lab generated one of the first knockout mice and has generated more knockout mice than any other lab in the world.[8] Mak’s role in advancing the use of genetically-altered mice in scientific study has led to important breakthroughs in immunology and understanding cancer at the cellular level. As of 2005, Amgen-produced papers have been cited more than 40,000 times. The basic research in cancer conducted by Mak has been published in top international scientific journals and he has given several keynote addresses at cancer symposia across Canada and the United States.

In 2004 Mak became the director of the Advanced Medical Discovery Institute and the Campbell Family Institute for Breast Cancer Research. He is also the senior scientist, division of Stem Cell and Developmental Biology, Advanced Medical Discovery Institute/Ontario Cancer Institute. He is a member of the Cancer Research Institute Scientific Advisory Council.[9] Since 1984, he has been a Professor in the Departments of Medical Biophysics and Immunology at the University of Toronto.

From the early 2000s, Mak concentrated his efforts on the emerging field of cancer metabolism. Mak, Lewis C. Cantley, and Craig B. Thompson together founded Agios, a biotech pharmaceutical company whose sole purpose is to discover methods of targeting cancer metabolism. The trio have contributed immensely in a few years to what was originally a forgotten paradigm. The discovery of the involvement of particular enzymes such as PKM2, mutated IDH as well as novel oncometabolites such as 2-hydroxyglutarate in cancer development have once again brought cancer metabolism back to the forefront of cancer biology.

Mak holds Honorary Doctoral Degrees from numerous universities in North America and Europe. He is an Officer of the Order of Canada and has been elected a Foreign Associate of the National Academy of Sciences (USA) as well as a Fellow of the Royal Society of London (UK.) He has won international recognition in the forms of the Emil von Behring Prize, the King Faisal Prize for Medicine, the Gairdner Foundation International Award, the Sloan Prize of the General Motors Cancer Foundation, the Paul Ehrlich and Ludwig Darmstaedter Prize and the Novartis Prize in Immunology.
