HNRNPU and non-small cell lung carcinoma: Previous studies report the function of hnRNP U as an mRNA stabilizer.24, 26, 27 Also, some works prove that hnRNP U exerts suppressive effect on NSCLC progression.24, 25 Therefore, we speculated that LIMD1‐AS1 regulated LIMD1 mRNA stability through hnRNP U. We confirmed the downregulated hnRNP U level in NSCLC cell lines (Figure 3B).
