YBX1 and esophageal squamous cell carcinoma: demonstrated a novel role of YBX1 in stabilizing the heparin‐binding growth factor (HDGF) mRNA by targeting the m5C‐modified site in bladder cancer.[7a] In consistency with this, we found that the expression of YBX1 was frequently upregulated in human ESCC tissues and was mainly localized in the cytoplasm.
