Increased Phospho-Keratin 8 Isoforms in Colorectal Tumors Associated with EGFR Pathway Activation and Reduced Apoptosis

<table>Tumor : normal abundance ratios according to stage. Graph shows the abundance ratio tumor (T) to matched normal mucosa (N) for total K8 and each phospho-serine K8 isoform, according to tumor stage. Horizontal line shows the 2-fold abundance ratio T : N. There was no significant difference in the means for each isoform abundance ratio among different stages.</table>
