Methylation-Associated Gene Silencing of RARB in Areca Carcinogens Induced Mouse Oral Squamous Cell Carcinoma
Figure 1
The progression of mouse model development for OSCC. (a) The ratio of carcinogenesis in mouse OSCC model. There were three treatments, 4-NQO/arecoline, 4-NQO, and arecoline. Mice were sacrificed at weeks 8, 12, 14, 18, 20, 26, and 28, respectively. The scoring criteria for mouse OSCC model are described in Section 2. (b) OSCC tongue tissues with tumors were excised, fixed, embedded, and sectioned for H&E staining. The mice that were treated with 4-NQO + arecoline would induce more serious OSCC formation than 4-NQO only and arecoline only. The order of severity was followed the time of treatment.
