To demonstrate typical staining, Figure 6C shows a CRC tissue sample from a representative patient with relatively low NDRG1 (i.e., NDRG1(−); Fig. 6C(i)) and relatively high nuclear β-catenin (i.e., nuclear β-catenin(+); Fig. 6C(ii)) and total CD44 (i.e., CD44(+); Fig. 6C(iii)). Here, CD44 is linked to colorectal carcinoma.
