Transcriptome profiling in oral cavity and esophagus tissues from (S)‐N′‐nitrosonornicotine‐treated rats reveals candidate genes involved in human oral cavity and esophageal carcinogenesis

Abstract excerpt

Recently, we have shown that (S)-N'-Nitrosonornicotine [(S)-NNN], the major form of NNN in tobacco products, is a potent oral cavity and esophageal carcinogen in rats. To determine the early molecular alterations induced by (S)-NNN in the oral and esophageal mucosa, we administered the carcinogen to rats in the drinking water for 10 wk and global gene expression alterations were analyzed by RNA sequencing. At a...
