STAT3 and esophageal squamous cell carcinoma: In mouse esophageal squamous cell carcinoma, CAFs-secreted Wnt family member (WNT2) has been linked to suppression of the DC-initiated antitumor T-cell response via the suppressor of cytokine signaling 3 (SOCS3)/phosphorylated Janus kinase 2 (p-JAK2)/phosphorylated STAT3 (p-STAT3) signaling pathway.
