LDHAP4 and neoplasm: Patients with high expression of oncogene pseudogenes had strikingly shorter survival than those with low expression (log-rank test; PDIA3P1, P = 0.046; LDHAP4, P = 0.004; LDHAP7, P = 0.014; EEF1A1P6, P = 0.025; EEF1A1P11, P = 0.007; Figure 2F), manifesting that high expression of oncogene pseudogenes might correlate with high malignancy of the tumor.
