Gene Expression of the D-Series Resolvin Pathway Predicts Activation of Anti-Tumor Immunity and Clinical Outcomes in Head and Neck Cancer.

Int J Mol Sci 2022 Jun 9;23(12). Epub 2022 Jun 9.

Department of Medical, Oral, and Biotechnology Science, University "G. d'Annunzio" Chieti-Pescara, 66100 Chieti, Italy.

In human medicine, the progression from early neoplasia development to either complete resolution of tumorigenesis and associated inflammation or chronicity and fatal outcomes remain difficult to predict. Resolution of inflammation is an active process that stimulates the termination of the inflammatory response and promotes return to homeostasis, while failure in resolution contributes to the development of a number of diseases. To understand how resolution pathways contribute to tumorigenesis, we defined and employed a cumulative score based on the expression level of genes involved in synthesis, signaling, and metabolism of the D-series resolvin (RvD).

Near-Infrared Photoimmunotherapy (NIR-PIT) in Urologic Cancers.

Cancers (Basel) 2022 Jun 17;14(12). Epub 2022 Jun 17.

Molecular Imaging Branch, Center for Cancer Research, National Cancer Institute (NIH), Bethesda, MD 20892, USA.

Near-infrared photoimmunotherapy (NIR-PIT) is a novel molecularly-targeted therapy that selectively kills cancer cells by systemically injecting an antibody-photoabsorber conjugate (APC) that binds to cancer cells, followed by the application of NIR light that drives photochemical transformations of the APC. APCs are synthesized by selecting a monoclonal antibody that binds to a receptor on a cancer cell and conjugating it to IRDye700DX silica-phthalocyanine dye. Approximately 24 h after APC administration, NIR light is delivered to the tumor, resulting in nearly-immediate necrotic cell death of cancer cells while causing no harm to normal tissues. Read More
