FN1 and cancer: The quantitative molecular analysis revealed that oral Fn was more abundant in the oral cavity (Median(Mdn) = 108.69 colony-forming units (CFU)/mL) than cancer tissue (Mdn = 4.78 CFU/mL) (Figure 1 and Supplementary Table S1) (Wilcoxon test: p = 0.004, robust test: p = 0.059, dunbiased (dunb) = 0 0.332) and adjacent tissue (Mdn = 2.19 CFU/mL) (Wilcoxon test: p < 0.001; robust test: p = 0.038, dunb = 0.382).
