Exon Array Analysis to Identify Diethyl-nitrosamine Differentially Regulated and Alternately Spliced Genes in Early Liver Carcinogenesis in the Transgenic Mouse ATT-myc Model
Abstract
Objectives: To identify the regulated genes or the spliced genes of diethylnitorsamine (NDEA) in ATT-myc mice versus control group. Methods: We analysed the 9 hybridizations on the MouseExon10ST array of NDEA treatments and control non- transgenic by application of a mixed model analysis of variance. Results: The 907 genes had regulated significantly between the groups and 916 genes had regulated with a significant exon-group interaction among of them 150 genes had regulated with both gene and possible splicing differences (p<0.01). The 7,618 genes had tested for the alternative gene up-regulation and splicing and compared to the gene-classifications. The genes functions, pathways and gene-classifications in the current study had presented in the contingency table analysis of the set of the regulated genes and alternatively spliced that regulated significantly in the ATT-myc mice treated by diethylnitorsamine versus control non-transgenic. The GOMolFn of gene-classification had 321 groups that had significantly regulated in the set of the regulated genes or differentially spliced. While the GOProcess of gene-classification had 330 groups that had significantly regulated in the set of differentially regulated genes or spliced. Additionally, the CELlLoc of gene-classification had 70 groups that had significantly regulated in the set of differentially regulated genes spliced. Finally, the Pathway gene-classification had 8 groups that had significantly regulated in the set of differentially regulated genes or spliced (p<0.01) in diethylnitorsamine when compared to control group. Conclusion: we summarized the toxicogenomics induced by diethylnitrosamine in early liver carcinogenesis in ATT-myc transgenic mice of liver cancer. Doi: 10.28991/SciMedJ-2021-0302-6 Full Text: PDF
