Sanford (Sandy) Markowitz is the Markowitz-Ingalls Professor of Cancer Genetics, a Distinguished University Professor at ÐÇ¿Õ´«Ã½, and co-leader of the GI Cancer Genetics Program at the Case Comprehensive Cancer Center. Sandy’s national distinctions include his being an NCI Outstanding Investigator (R35) Awardee and his also being Principal Investigator of the Case GI SPORE, an NCI recognized national center of excellence for research in gastrointestinal cancers.
My research is primarily focused on the molecular biology of colon cancer, functional influence of oncogenes and suppressor genes on transformation, metastasis, and response to therapies.

Research Projects
The Markowitz laboratory is recognized as a national leader in studies of the genetics and epigenetics of GI cancers, including in basic discovery of genetic targets in GI cancers and in translational studies aimed at developing new methods for early cancer detection, prevention, and treatment.
Highlights of studies from the Markowitz laboratory include: identifying TGF-beta as a key human tumor suppressor; identifying the first cancer associated mutations in the TGF-beta signaling pathway (mutations in TGF-beta type II receptors); identifying 15-prostaglandin dehydrogenase (15-PGDH), a prostaglandin degrading enzyme, as a novel effector of TGF-beta mediated tumor suppression and as a negative regulator of tissue stem’s repair of tissue injury; developing the first in-vivo active 15-PGDH inhibitor drugs and demonstrating their activity in potentiating tissue repair in multiple disease models that include potentiating healing of colitis and accelerating hematopoietic recovery following bone marrow transplantation; being part of the team that sequenced the first human cancer coding genome (the colon cancer genome); discovering key epigenetic markers of colon cancers and esophageal cancers; pioneering development of the first commercial stool DNA based test for colon cancer detection, based on aberrantly methylated DNA (ColoSure); pioneering development of the first commercial non-endoscopic DNA based tests for detecting esophageal cancers and their precursor lesions of Barrett’s esophagus (via engineering the EsoCheck esophageal sampling device and developing the EsoGuard methylated DNA panel assay).
Sandy’s translational advances have led to founding of two biotechnology companies, Rodeo Therapeutics (for development of 15-PGDH inhibitor drugs) and LucidDx (for development of non-endoscopic DNA testing for esophageal neoplasias). Sandy’s work on developing diagnostic tests for detecting esophageal neoplasia was reported as a highlight advance in the 2020 NCI Director’s report to Congress. In 2020 Sandy’s EsoGuard DNA assay was awarded breakthrough device designation by the FDA and his EsoCheck sampling device won FDA approval. More broadly, Sandy’s multiple contributions to GI Cancer genetics have been recognized by his winning the Hamdan Award for Medical Research Excellence from the Kingdom of Dubai.
