23812217-9	2013	In vitro treatment with 4-NQO altered expression of RARbeta2, p-ERK1/2, and COX2 in human esophageal cancer cells.	4-Nitroquinoline-1-oxide	24-29	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	76-80	
23812217-13	2013	CONCLUSION: 4-NQO-induced cancer in oral cavity and esophagus of mice not only pathologically and morphologically mimicked human oral and esophageal cancer, but also shared some molecular alterations (e.g. aberrant expression of Rarb2, p-ERK1/2, and Cox2).	4-Nitroquinoline-1-oxide	12-17	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	250-254
