Genome-wide tongue epithelia transcriptomic profiles from K14-rtTA;TRE-FLBmi-1 (KrTB), KrTB+Doxycycline (KrTB-D), KrTB+4-nitroquinoline 1-oxide (KrTB-N), and KrTB+Doxycycline+4-nitroquinoline 1-oxide (KrTB-DN).

ABSTRACT: We developed a transgenic mouse model (truncated K14-rtTA; TRE/Bmi1, KrTB) containing a doxycycline- (dox) controlled, Tet-responsive element system to selectively overexpress BMI1 only in the basal epithelial SCs of the tongue. Here, we used this model to delineate BMI1 actions in tongue epithelia during oral tumorigenesis (as induced by 4-nitroquinoline 1-oxide, 4-NQO). Genome-wide transcriptomics indicated that mRNAs associated with human OSCC, including SOX9, HIF1A, MMP9, INHBB, and MYOF, were further increased by ectopic BMI1 expression in murine tongue epithelia. mRNAs encoding multiple metabolic targets, such as SLC2A1 (GLUT1), PKM, LDHA, and HK2, were also increased upon BMI1 overexpression in 4-NQO-treated tongue epithelia.

Genome-wide tongue epithelia transcriptomic profiles from K14-rtTA;TRE-FLBmi-1 (KrTB) and KrTB+Doxycycline (KrTB+DOX).

Project description:We developed a transgenic mouse model (truncated K14-rtTA; TRE/Bmi1, KrTB) containing a doxycycline- (dox) controlled, Tet-responsive element system to selectively overexpress Bmi1 only in the basal epithelial SCs of the tongue. Here, we used this model to assess Bmi1 actions in tongue epithelia. Genome-wide transcriptomics revealed increased levels of transcripts involved in the cellular response to hypoxia in Bmi1-overexpressing (KrTB+DOX) mice.

Genome-wide analysis of gene expression changes in mouse tongue squamous cell carcinomas induced by 4-nitroquinoline 1-oxide (4-NQO)

Project description:We hypothesized that the expression of many genes are dysregulated during oral cancer carcinogenesis. We examined genome-wide transcript levels in normal mouse tongues and the tongue squamous cell carcinomas induced by 4-NQO. The results will provide important information for the diagnosis, prevention, and treatment of human oral cancers, including tongue cancer. Total RNA obtained from normal tongues (not treated with 4-NQO) and tongue squamous cell carcinomas induced by 4-NQO.

Genome-wide changes in transcript levels in tongues after 4-NQO and ethanol treatment

Project description: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.
