Effects of C-Phycocyanin on the representative genes of tumor development in mouse skin exposed to 12-O-tetradecanoyl-phorbol-13-acetate.

C-Phycocyanin (C-PC), a biliprotein from the sea weed, has been shown to have the beneficial effects like antioxidant, anti-inflammatory, neuroprotective, and hepatoprotective properties and is used as food supplement. We are showing the effect of C-Phycocyanin on the early events altered by tumor promoter. TPA induced the expression of critical events of tumorigenesis like ornithine decarboxylase, cyclooxygenase-2, interleukin-6 and pSTAT3 in mouse skin after 5h of application, whereas expression of transglutaminase2 was decreased at this time point.
