The Dysregulation of Polyamine Metabolism in Colorectal Cancer Is Associated with Overexpression of c-Myc and C/EBPβ rather than Enterotoxigenic Bacteroides fragilis Infection

Figure 1

(a) Enterotoxigenic B. fragilis (ETBF) DNA copy number per 50 ng of total extracted DNA in paired samples of colorectal cancer (logarithmic scale). (b) SMOX expression level relatively to two reference genes: RPN1 and GUSB. The samples with high rates of ETBF colonization tend to have higher expression of SMOX, especially in normal tissue (compared to the other norms). However, no statistically significant correlation between SMOX expression and ETBF colonization was observed.
