The Parsons laboratory seeks to investigate tumor suppressor and oncogene signaling pathways that are altered in human solid tumors using a multidisciplinary approach that includes genetics, biochemistry, bioinformatics, and pathology.  Thematic topics that are currently under investigation include dissection of the regulation and function of the PTEN tumor suppressor, determination of the impact of altered PTEN signals in cancer progression and altered energy metabolism, molecular pathogenesis of breast carcinoma initiation and progression, and examination of epigenetic and chromatin reprogramming as consequence of altered cancer signal pathways.  Past accomplishments include discovery of PTEN, elucidation of the frequent alteration of the PI3K/PTEN pathway in a wide variety of cancers, generation of mouse models of cancer due to PTEN mutation, and identification of PREX2 as a regulator of PTEN function.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device, biotechnology companies, and other outside entities to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their outside financial relationships.
