Using the hamster cheek pouch carcinogenesis model, we explore which fluorescence excitation wavelengths are useful for the detection of neoplasia. 42 hamsters were treated with DMBA to induce carcinogenesis, and 20 control animals were treated only with mineral oil. Fluorescence excitation emission matrices were measured from the cheek pouches of the hamsters weekly. Results showed increased f...
The molecular messenger nitric oxide (NO) is synthesized endogenously from L-arginine by three isoforms of the enzyme NO synthase. The isoform most consistently associated with neoplasia is the inducible form, inducible nitric oxide synthase (iNOS). However, the role played by the NO/iNOS system in tumor development is complex, and both promoting and inhibitory effects on neoplasia have been re...
cancer is a genetic-epigenetic based disease which contains a complex of alterations that cause irreversible transformation of cells with a new anarchic behavior. tumor suppressor inactivation and/or oncogene activation will lead to tumorigenesis. based on the genetic alteration in germ or somatic cells, the affected person will have a different fate of cancer incidence or inheritable cancer su...
