Moreover, strong green fluorescence signals were detected in both tumors of the HRMTF-treated mice after terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) assay kit staining (Fig. 6H), indicating the high level of cell apoptosis in the HRMTF-treated tumor tissues. The gene discussed is DNTT; the disease is neoplasm.
