ODC1 and squamous cell carcinoma: The curcumin usage in the study also showed positive results, indicating its protective action against Electron beam radiation.19 Also, it has been found that topical application of curcumin in epidermis of CD-1 mice significantly inhibited UVA-induced ornithine decarboxylase ornithine decarboxylase (ODC) activity and prevented apoptotic changes in human epidermoid carcinoma A431 cells.32 To complement the information obtained by X-ray diffraction analysis, enamel sample was further characterized by Fourier Transmission infrared (FTIR) spectroscopy.
