The results of miRNA microarray analysis confirmed that miR‐499a‐5p was significantly up‐regulated in glioma cells with ZNRD1‐AS1 knockdown, indicating that miR‐499a‐5p may be involved in the regulation of glioma cells induced by ZNRD1‐AS1 (Figure S1). The gene discussed is POLR1H; the disease is central nervous system cancer.
