Expression of APC is often decreased and inversely correlated with miR-494 expression in human CRC tissues. a Immunohistochemical staining of APC in tumor tissue and corresponding normal colonic epithelium. Normal epithelium shows vesicular brown cytoplasmic APC staining. This staining is nearly absent in the tumor tissue. b APC mRNA expression is frequently decreased in tumor tissues when compared to the matched non-cancerous tissues, as evaluated by real-time PCR. c The relative levels of miR-494 expression were plotted against the relative levels of APC mRNA expression
