Long-term psoralen plus ultraviolet A radiation (PUVA) therapy is associated with an increased risk of squamous cell carcinoma and malignant melanoma. Genistein (4',5,7-trihydroxyisoflavone), a major isoflavone in soybeans and a specific inhibitor of protein tyrosine kinase, has been shown to
The effect of UV irradiation on the skin was investigated in (WB-W/+) X (C57BL/6J-Wv/+)F1-W/Wv mice, which are genetically deficient in tissue mast cells. Their congenic littermates (+/+) and normal albino mice (ICR or BALB/c) were used as controls. Mice were irradiated with 500 mJ/cm2 of UVB and
The goal of this study was to design a model system for the assessment of phototoxic potential using a human reconstructed epidermis (HRE, SkinEthic Laboratories, Nice, France), by testing some representative phototoxic (P) and non-phototoxic (NP) compounds and finished topical products. The tissue
Extracorporeal Photochemotherapy (ECP) consists in illumination of the patient's leukocytes in the presence of 8-Methoxy Psoralen (8-MOP) and its reinjection to the same patient. ECP is responsible for many cellular events, the most important being the induction of cell apoptosis. Apoptosis appears
