KRT88P and neoplasm: Although HBc proteins were expressed by both tumor and adjacent non-tumor liver tissues from eleven of these patients, the level of HBc was higher in each tumor than in the adjacent non-tumor tissue (Figure 2, panel 5, lanes 1–6 and 9–22); the exceptions were patient No. 6, who had undetectable HBc protein and patient No. 34, who had same level of HBc protein.
