Over-expression of Nectin-2 mRNA in cancer tissues. A box and whisker plot of the expression level of Nectin-2 mRNA in normal tissues and cancer tissues. The vertical axis represents Nectin-2 mRNA expression level. Nectin-2 mRNA expression in the indicated tissues was analyzed using Affymetrix U_133 arrays as described in Methods. The whiskers indicate the minimum and maximum values. The box indicates the 25th–75th percentile. N, normal tissues; C, cancer tissues. ***, p < 0.0001; **, p < 0.01; *, p < 0.05 as determined by the Mann Whitney test.
