Development of heat shock protein 90-targeted PDT for inflammatory breast cancer

Motivation of the study In photodynamic therapy (PDT), systemically administered photosensitizer is activated within the tumor using focused near-infrared light, typically a laser with a wavelength matching the absorption peak of the photosensitizer. Several photosensitizers have been clinically approved for the treatment of different cancers; however, their accumulation is non-tumor exclusive which exposes healthy tissues to side effects like daylight-induced phototoxicity. A promising strategy to improve tumor selectivity is to couple photosensitizer to a tumor-targeting agent that binds to a specific antigen expressed on the Continue reading →Customer case Research by: Duke University, founded in 1924, is one of the leading and wealthiest private research universities in the USA. The most notable Duke alumni is President Richard Nixon. Research at Duke University has been awarded with several Nobel prizes in recent years for groundbreaking discoveries in biochemistry and medicine, such as G-protein coupled receptors, DNA mismatch repair, and cellular regulation of hypoxia.
