Variations of transcriptome along intestinal  of mice under two-month food arsenic exposure
After 2 months arsenic exposure, among the 33,492 surveyed genes, 13,005 genes were detected with expression (mean FPKM > 1) in 27 samples of the intestinal tracts (ileum, cecum, and colon) of control and test mice. Among the detected genes, and in comparison to the control and test mice, 328, 579 and 90 dierentially expressed genes (DEGs) were obtained from ileum, cecum, and colon, respectively (FDR < 0.05, Log2 Fold Change > 1). To explore the potential functions of DEGs in the three intestines, we performed GO and KEGG pathway enrichment analysis. Analysis revealed by machine learning of the transcriptome results showed that significantly affected the gene network of pathways related to disease and immunity in the intestine. The results demonstrated that food arsenicals change the intestinal transcriptome significantly, suggest that the host genes might participate in arsenical biotransformation.
