Singlet oxygen (1O2) is generated by a number of enzymes as well as by UV or visible light in the presence of a sensitizer and has been proposed as a damaging agent in a number of pathologies including cataract, sunburn, and skin cancers. Proteins, and Cys, Met, Trp, Tyr and His side chains in
The current study examined the chemopreventive potential of the dual-function JAK3/EGFR tyrosine kinase inhibitor WHI-P131 (CAS 202475-60-3) in photocarcinogenesis of non-melanoma skin cancer (NMSC). Prophylactic WHI-P131 exhibited significant anti-inflammatory activity in the SKH-1 mouse model of
The incidence of skin cancer is higher than all other cancers and continues to increase, with an average annual cost over $8 billion in the United States. As a result, identifying molecular pathway alterations that occur with UV exposure to strategize more effective preventive and therapeutic
Tyrosinase is a multifunctional copper-containing enzyme widely distributed in plants and animals, which catalyzes both the hydroxylation of tyrosine into o-diphenols and the oxidation of o-diphenols into o-quinones. Tyrosinase is known to be a key enzyme for melanin biosynthesis in plants and
The skin, the largest organ of the body, plays an important role in the total metabolism of several hormones. Melanin, the major product of the melanocyte, is largely responsible for the coloring of skin. Melanin is a complex of insoluble, polyquinone, brown or red pigment and protein, formed by the
Chronic pain presents a huge economic and social burden, with existing treatments largely unable to satisfy medical needs. Recently, studies have shown that nerve growth factor (NGF) is a major mediator of inflammatory and neuropathic pain, providing a new therapeutic target. Although originally
Vandetanib therapy is a novel once-daily oral multitargeted tyrosine kinase inhibitor, which is currently used in advanced or metastatic medullary thyroid cancer. Skin toxicities are among the most prevalent adverse events reported with this targeted therapy (e.g. acne-like rash, hand-foot skin
Isoflavones derived from many edible plants have been reported to possess significant antioxidant, estrogenic and tyrosine kinase inhibitory activity. Genistein has been found previously to provide protection from oxidative damage induced by UV radiation both in vitro and following dietary
Tea is one of the most widely consumed beverages worldwide, and is available in various forms. Green tea is richer in antioxidants compared to other forms of tea. Tea is composed of polyphenols, caffeine, minerals, and trace amounts of vitamins, amino acids, and carbohydrates. The composition of the
