Jack Pledger, PhD
Associate Director, Basic Sciences, Tampa General Hospital

Warren Jackson "Jack" Pledger is the Associate Director of Basic Sciences at the TGH Cancer Institute. Pledger’s research focuses on the mechanisms governing cell cycle progression. He was the first to show that the cell cycle is regulated by a series of sequential events and to hypothesize that dysfunction of these events could trigger transformation or cancer. His pioneer studies demonstrated the role of growth factor-regulated cyclin-dependent kinase (CDK) activity in the control of cellular proliferation, and used mouse models to explore the role of CDK activity in tumor formation. His recent projects address the impact of signal transduction pathway inhibition on tumor cell survival, and the hallmarks of cancer during the evolution of tumor progression seeking to find new therapeutic approaches.

Having received peer-reviewed research funding for more than 30 years, Pledger has held numerous National Institutes of Health (NIH) and NCI grants. He has been associate editor for numerous publications, including Molecular and Cellular Biochemistry, American Journal of Physiology, Cancer Research, and Journal of Cellular Biochemistry. His professional memberships and appointments include the NIH Study Section – Cellular Biology and Physiology II, American Cancer Society – Institutional Research Grants Advisory Committee as well as many NIH and NCI review panels. The more than 150 articles Pledger has authored or co-authored have been published in top-tier scientific journals such as Nature, the Proceedings of the National Academy of Sciences, and Molecular Cell Biology among others.

Pledger earned his PhD at Purdue University, West Lafayette, Indiana, and master’s of science and bachelor’s of science from the University of Houston.
