Howard E. Boudreau, Ph.D.

Major Areas of Research

  • NADPH oxidase (NOX) enzyme function 
  • Inflammation
  • Wound healing
  • Cancer metastasis

Program Description

We are currently investigating the role of mutant p53-induced NOX4 on the cancer cell secretome, and the effects NOX4-derived reactive oxygen species have on the inflammatory tumor microenvironment.



Ph.D., 2006, Georgetown University

Howard Boudreau obtained his Ph.D. in Biochemistry and Molecular & Cellular Biology from Georgetown University in 2006. His graduate work focused on identifying and characterizing novel effector targets of the Raf-1/ERK signaling pathway in metastatic breast cancer. As a post-doctoral fellow at NIH/NIAID, he focused on roles of NADPH oxidase (NOX) enzymes in TGF-beta-mediated inflammation and wound healing. In 2014, he joined the Molecular Defenses Section (MDS) as a Staff Scientist in the Laboratory of Clinical Immunology and Microbiology (LCIM) and studies how tumor-associated mutant p53 proteins and NOX4 contribute to cancer cell migration and inflammation.
