HNRNPAB and esophageal squamous cell carcinoma: Evidence indicates that hnRNPAB is engaged in regulating key biological processes, including gene transcription[37, 38, 39] and RNA splicing.[40] Analysis of TCGA ESCC RNA‐seq data revealed that genes positively correlated with HNRNPAB expression are enriched in RNA polymerase and spliceosome pathways (Figure S13A, Supporting Information).
