TGM2 and neoplasm: Moreover, average tumor weights from MKN45/TG2-shRNA and NCI-N87/TG2-shRNA cells were significantly lower than weights of tumors from MKN45/TG2-NC and NCI-N87/TG2-NC cells (MKN45/TG2-shRNA: 0.20±0.06 g; MKN45/TG2-NC: 0.46±0.12 g; MKN45/TG2-shRNA vs. MKN45/TG2-NC: P < 0.05; NCI-N87/TG2-shRNA: 0.52±0.10 g; NCI-N87/TG2-NC: 1.07±0.13 g; NCI-N87/TG2-shRNA vs. NCI-N87/TG2-NC: P < 0.05) (Figure 5D).
