To analyze the protein expression of HGF and c-MET in gastric cancer, we searched The Human Protein Atlas (HPA) database and found that HGF and c-MET are highly expressed in the cytoplasm and plasma lemma of the gastric cancer cells belonged to the same patients (the images derived from the Human Protein Atlas (HPA) (http://www.protein atlas.org/)) (Figure 1A). This evidence concerns the gene HGF and gastric cancer.
