WDFY3 and esophageal squamous cell carcinoma: Further investigation from Ago2‐RIP experiment revealed that miR‐2355‐5p was the highest enriched miRNAs among all miRNAs in ESCC cells harbouring WDFY3‐AS2 overexpression, compared to the pcDNA3.1 group (Figure S3), suggesting that WDFY3‐AS2 may bind to miR‐2355‐5p through the Ago2‐dependent pathway (Figure 5E).
