As shown in Figure 6D, the expression of SLC27A2, SFRP2, KRT17 were up-regulated in tumor tissues (p<0.05), the expression of TAGLN was down-regulated (p<0.05), while those of NAT2 remained unchanged (p>0.05), compared with the levels in the corresponding normal tissues. The gene discussed is SFRP2; the disease is neoplasm.
