NUDT4 and neoplasm: Our results showed that the relative expression of ENST00000413528 or lnc‐NUDT4‐4:1 was higher in tumor tissues than that in PTBE tissues (P < 0.05), while NONHSAT207178 and NONHSAT174301 were downregulated in tumor tissues (P < 0.05), all of which were consistent with the microarray results.
