Genome-wide changes in transcript levels in tongues after 4-NQO and ethanol treatment
Ontology highlight
ABSTRACT: Tobacco use and alcohol consumption are two major contributing factors for head and neck squamous cell carcinoma (HNSCC) carcinogenesis. We combined the 4-nitroquinoline-1-oxide (4-NQO) oral carcinogenesis mouse model and the Meadows-Cook alcohol mouse models and performed next generation genome-wide RNA-sequencing of tongues. We determined changes in transcript levels in four groups: 4-NQO followed by ethanol treatment (4-NQO/EtOH), 4-NQO followed by normal drinking water (4-NQO/Untr.), vehicle control followed by ethanol treatment (V.C./EtOH), and vehicle control followed by normal drinking water (V.C./Untr.). We found that the 494 gene transcripts were significantly changed (at least a 2-fold change where p<0.05) in the V.C./EtOH group compared to the V.C./Untr. group. The 4-NQO/Untr. group had 1,808 transcripts significantly changed compared to the V.C./Untr group, while the 4-NQO/EtOH group had 3,606 significantly changed transcripts as compared to the V.C/Untr. group. This study is the first to show that 4-NQO followed by ethanol cause the largest number of changes in transcript levels in the tongue.
