HSP90B2P and lip and oral cavity carcinoma: 7,12-Dimethylbenz[a]anthracene (DMBA) induced oral carcinoma showed reduction at the emission of collagen, nicotinamide adenine dinucleotide (NAD), and flavin adenine dinucleotide (FAD) but with the oral administration with HSP and its nanoparticles restore the endogenous fluorophores emission and higher redox ratio in the buccal mucosa of DMBA animal [100].
