RPS19 and neoplasm: Regarding the lectins recognizing ABO blood group antigens, the significant lower signals were detected in the tumor regions with P < 0.01 for EEL (for the B blood group antigen), DBA (for the A blood group antigen), PTL-I (for the A and B blood group antigens), GSL-I-A4 (for the A blood group antigen), and TJA-II (for H antigen), but not for UEA-I (for H antigen); the signal of GSL-I-B4 was not detected in either sample (Figure 6B and Table 2).
