Consistent with the above findings, tumors induced by p4-MT1M transfected HepG2 cells showed significantly smaller mean tumor volume, but tumors induced by siR-MT1M transfected HepG2 cells showed significantly larger mean tumor volume, than tumors induced by siR-NC transfected or nontransfected HepG2 cells (Figure 2C). This evidence concerns the gene MT1M and neoplasm.
