We did quantitative PCR analysis of cytochrome c oxidase (Cox) I and Cox II genes to measure changes in mtDNA content in pretreatment and posttreatment salivary rinses obtained from 76 patients undergoing surgical resection for primary head and neck squamous cell carcinoma.
We did quantitative PCR of cytochrome c oxidase I (Cox I) and cytochrome c oxidase II (Cox II) genes on oral rinse samples obtained from 94 patients with primary head and neck squamous cell carcinoma (HNSC) and a control group of 656 subjects.
COX-2 Docking Structural Analysis with Phytochemical Extracts of Rosemary: A Possible Cytotoxicity on Head and Neck Squamous Cell Carcinoma Cell Line (HEp-2).
Restoration of E-cadherin expression by selective Cox-2 inhibition and the clinical relevance of the epithelial-to-mesenchymal transition in head and neck squamous cell carcinoma.
There was overexpression of COX-2 and its downstream enzyme mPGES-1, and their localization in tumor cells was similar, suggesting that these enzymes play both an important role in the development and proliferation of HNSCC.
Western blot analyses of the several stage IVA HNSCC primary tumors have shown reduction in the expression of COII and ATP5A of the OXPHOS complexes IV and V subunits, respectively.
The results presented here show that HNSCC tumoral lesions and their derived cell lines constitutively express COX-2 and the EP1, EP2 and EP3 receptors for PGE2.
