In the HPA data, compared with normal tissues, the expression of PKMYT1, ETF1, RECQL4, TUBB2B, and CDC6 in tumor tissues was remarkably upregulated, while the expression of TFRC and PITX1 was significantly downregulated (,ECT2, BUBB1B, and COCH were not included) (Figure 7B). The gene discussed is ETF1; the disease is neoplasm.
