David Andrew Sinclair was born in Australia in 1969, and he grew up in St Ives, New South Wales. His paternal grandmother had emigrated to Australia following the suppression of the Hungarian Uprising of 1956, and his father changed the family name from Szigeti to Sinclair.
Education and career
Sinclair obtained a Bachelor of Science at the University of New South Wales, Sydney, and received the Australian Commonwealth Prize. In 1995, he received a Ph.D. in Molecular Genetics from the same school, focusing on gene regulation in yeast. In 1993, he met Leonard P. Guarente, a Massachusetts Institute of Technology professor who studied genes involved in the regulation of aging, when Guarente was on a lecture tour in Australia, and the meeting spurred Sinclair to apply for a post-doc position in Guarente's lab. Earlier that year Cynthia Kenyon's lab at UCSF had discovered that a single-gene mutation in (Daf-2) could double the lifespan of C. elegans.
In 1999, Sinclair was hired at Harvard Medical School. In 2003, his lab was small and struggling for funding. In 2004, Sinclair met with the philanthropist Paul F. Glenn who donated $5 million to Harvard to establish the Paul F. Glenn Laboratories for the Biological Mechanisms of Aging at Harvard, of which Sinclair became the founding Director. He currently serves as the co-Director with Bruce Yankner.
In 2004, Sinclair, along with serial entrepreneur Andrew Perlman, Christoph Westphal, Richard Aldrich, Richard Pops, and Paul Schimmel, founded Sirtris Pharmaceuticals. Sirtris was focused on developing Sinclair's research into activators of sirtuins, work that began in the Guarente lab. The company was specifically focused on resveratrol formulations and derivatives as activators of the SIRT1 enzyme; Sinclair became known for making statements about resveratrol like: “(It's) as close to a miraculous molecule as you can find.... One hundred years from now, people will maybe be taking these molecules on a daily basis to prevent heart disease, stroke, and cancer.” Most of the anti-aging field was more cautious, especially with regard to what else resveratrol might do in the body and its lack of bioavailability. The company's initial product was called SRT501, and was a formulation of resveratrol.; Sirtris went public in 2007 and was subsequently purchased and made a subsidiary of GlaxoSmithKline in 2008 for $720 million.
In 2006, Genocea Biosciences was founded based on work of Harvard scientist Darren E. Higgins around antigens that stimulate T cells and the use of these antigens to create vaccines; Sinclair was a co-founder.
In 2008, Sinclair joined the scientific advisory board of Shaklee and helped them devise and introduce a product containing resveratrol called "Vivix"; after the Wall Street Journal requested an interview about his work with the company and its marketing, he disputed the use of his name and words to promote the supplement, and resigned.
In 2011, Sinclair was a co-founder of OvaScience with Michelle Dipp (who had been involved with Sirtris), Aldrich, Westphal, and Jonathan Tilly, based on scientific work done by Tilly concerning mammalian oogonial stem cells and work on mitochondria by Sinclair. Tilly's work was controversial, with some groups unable to replicate it.
In 2015, Sinclair described to The Scientist his efforts to get funding for his lab, how his lab grew to around 20 people, shrunk back down to about 5, and then grew again as he brought in funding from philanthropic organizations and companies, including companies that he helped to start. As of 2015[update], his lab had 22 people and was supported by one R01 grant and was 75% funded by non-federal funds.
In 2018, Sinclair was made an Officer of the Order of Australia (AO) for "distinguished service to medical research into the biology of ageing and lifespan extension, as a geneticist and academic, to biosecurity initiatives, and as an advocate for the study of science".
While Sinclair was in Guarente's lab, he discovered that Sirtuin 1 (called sir2 in yeast) slows aging in yeast by reducing the accumulation of extrachromosomal rDNA circles. Others working in the lab at the time identified NAD as an essential cofactor for sirtuin function. In 2002, after he had left for Harvard, he clashed with Guarente at a scientific meeting at Cold Spring Harbor Laboratory, challenging Guarante's description of how sir2 might be involved in aging; this set off a scientific rivalry.
In 2003, when his lab was still small, Sinclair learned that scientists at a Pennsylvania biotech company called Biomol Research Laboratories discovered that polyphenols including resveratrol could activate sir2, and he collaborated with them to confirm this. This led to publications authored in part by Sinclair in both Nature and Science in 2003. Sinclair's outspoken advocacy for resveratrol as an anti-aging compound started a scientific controversy over whether this was true, and whether resveratrol even activated sirtuins. Work in another lab, done partially with funding from Sirtris, found increases in the number of mitochondria in the cells of mice given high doses of resveratrol. Sinclair's lab continued to work on reservatrol and analogs of it, as well as on mitochondria and NAD, all directed to understanding aging and how to prevent it.
