K8 expression in cancer tissue. Panels Ai-iii shows various examples of K8 expression scores in cancer tissue. Panel B: A significant difference of K8 expression in cancer tissue was observed between high (mean = 5.46 mM) and low butyrate (mean = 2.36 mM) groups (p = 0.0056). Panel C shows immunoblots for K8 in cancer tissue: a total 8 samples were used, 4 with high faecal butyrate levels and 4 with low faecal butyrate levels. Panel D: Densitometry result shows an inverse relationship between faecal butyrate levels and K8 expression in the cancer tissue.
