Chemoprevention of photocarcinogenesis by selected dietary botanicals.
Epidemiological, clinical and laboratory studies have implicated solar ultraviolet (UV) radiation as a tumor initiator, tumor promoter and complete carcinogen, and their excessive exposure can lead to the development of various skin disorders including melanoma and nonmelanoma skin cancers. Sunscreens are useful, but their protection is not adequate to prevent the risk of UV-induced skin cancer...
متن کاملBotanical antioxidants for chemoprevention of photocarcinogenesis.
The incidence of non-melanoma skin cancer, consisting of basal- and squamous- cell carcinoma, continues to increase in the United States and elsewhere. Solar ultraviolet (UV) B radiation has been implicated as its main cause. This adverse effect of UVB has become a major human health concern. Therefore, development of novel strategies to reduce the occurrence of skin cancer is a highly desirabl...
متن کاملChemoprevention of prostate cancer with lycopene in the TRAMP model.
BACKGROUND Dietary lycopene combined with other constituents from whole tomatoes was previously found to have greater chemopreventive effects against prostate cancer as compared to pure lycopene provided in a beadlet formulation. We hypothesized that tomato paste would have greater chemopreventive effects in transgenic adenocarcinoma of the mouse prostate (TRAMP) mice relative to equivalent lyc...
متن کاملMolecular mechanisms of photocarcinogenesis.
Photocarcinogenesis represents the accumulation of genetic changes as well as immune system modulation, which ultimately lead to the development of skin cancers. The recent advances in molecular and cellular biology have clarified the mechanisms of photocarcinogenesis, including the formation of DNA photoproducts, DNA repair, mutation of proto-oncogenes and tumor suppressor genes, and UV-induce...
متن کاملPhotoimmune suppression and photocarcinogenesis.
The primary cause of non-melanoma skin cancer, the most prevalent form of human neoplasia, is the ultraviolet (UV) radiation found in sunlight. Exposing mice to UV radiation induces skin cancers that are highly antigenic. Upon transfer of an UV-induced skin cancer to a normal syngeneic mouse, the tumor cells are recognized and rapidly destroyed by the immune system of the recipient. This raises...
