Proteomic analysis of gastric cancer and immunoblot validation of potential biomarkers

Figure 4 Examples of immunoblotting results on four pairs of non-tumor and tumor tissue for eight differentially expressed proteins (A) and densitometric results from immunoblotting for the same eight proteins (B). The x-axis represents non-tumor (N) and tumor (T) tissues and the y-axis represents relative band density. The P values are from the Wilcoxon signed-rank test. GKN1: Gastrokine-1 precursor; MRPL12: 39S ribosomal protein L12 (mitochondrial precursor); PACAP: Plasma cell-induced resident endoplasmic reticulum protein; GSTM3: Glutathione S-transferase mu 3; SEPT2: Septin-2; UBE2N: Ubiquitin-conjugating enzyme E2 N; TALDO1: Transaldolase; TPT1: Translationally controlled tumor protein.
