Edward Maytin, MD PhD

Visiting Scientist

Edward Maytin, MD, is Section Head of Molecular Dermatology in the Department of Dermatology, as well as a Staff Member in the Department of Biomedical Engineering at the Cleveland Clinic. He is also an Assistant professor of Chemistry and Biomedical Engineering at Cleveland State University and Assistant Professor in the Department of Molecular Medicine at the Cleveland Clinic Lerner College of Medicine at Case Western Reserve University.

A frequent collaborator with the Hasan Lab, Dr. Maytin’s research focuses on two thematic areas: (1) wound healing, and (2) skin cancer. For wound healing, we are interested in the role of the extracellular matrix in wound repair. A large carbohydrate molecule called hyaluronan is an abundant component of the matrix and also of the pericellular coats of fibroblasts, epithelial cells, and blood vessels; the addition of certain proteins to hyaluronan after injury appears to be critical for regulating inflammation and fibrosis in healing wounds. Understanding this regulation may provide new ideas for therapy of poorly healing wounds in diabetes.

For skin cancer, we are working to improve a skin cancer treatment called photodynamic therapy (PDT). PDT has two components: a porphyrin precursor that is selectively taken up into malignant cells and converted to porphyrin, and a strong light source that activates the porphyrin inside the cancer cells, producing oxygen free radicals and causing cell death. Under the proper conditions, PDT can also stimulate anti-tumor immunity. We have found that pretreatment with certain drugs and hormones (including methotrexate and Vitamin D) can lead to more porphyrin accumulation, more efficient cell killing upon exposure to light, and improved stimulation of anti-tumor immune mechanisms.
