Association of colorectal cancer with pathogenic Escherichia coli: Focus on mechanisms using optical imaging

Figure 1 Correlation of tumor volume (HCT116 cells xenograft) and 2-DG-750 fluorescence signal uptake. A: Representative animal images showing the increase in fluorescence signal intensity with tumor development (day 17 and day 24 post-xenograft); B: Correlation between tumor development determined using a caliper and increase in fluorescence signal intensity (Pearson’s correlation factor r = 0.4197; P = 0.0036).
