Compared to the normal tissues (Fig. 3A), ZDHHC2 expression was almost negative in patients with poorly differentiated carcinoma (G3) (Fig. 3B), while weak ZDHHC2 expression (G2) and strong ZDHHC2 expression (G1) were found in moderately differentiated gastric cancer and well-differentiated gastric cancer respectively (Fig. 3C and 3D). The gene discussed is ZDHHC2; the disease is carcinoma.
