Correlation of Epstein-Barr virus and its encoded proteins with Helicobacter pylori and expression of c-met and c-myc in gastric carcinoma

Figure 1 Immunohistochem-istry of c-met and c-myc. A: Positive expression of c-met; B: Negative expression of c-met; C: Positive expression of c-myc; D: Negative expression of c-myc. (Original magnification ×400).

Figure 2 Detection of EBV-associated gene expression by RT-PCR and Southern hybridization in EBVaGC. M: DIG-labeled DNA molecular weight marker VIII (Roche); lane 1: EBV-positive LCL (positive control); lane 2: EBV-negative Ramos cells (negative control); lanes 3-13: EBV-positive gastric carcinoma samples.
