DDIT4 and neoplasm: The mean expression level (based on H-score) of DDIT4 was 80 in tumor samples (in all expression); however, the mean expression of DDIT4 was 20 in the nucleus, 30 in the cytoplasm, and 32 in the membranous in adjacent normal tissue, indicating that the expression of DDIT4 in PTs was high compared to adjacent normal tissues (Table 2 and Fig. 4).
