AQP5 and EGFR interaction in tumor biology. AQP5 induces extracellular receptor kinase (ERK1/2) pathway activation via activation of the epidermal growth factor receptor (EGFR), leading to facilitating tumor proliferation and metastasis. Besides, AQP5 is phosphorylated followed by binding to the SH3 domain of Src to promote epidermal mesenchymal transition (EMT) activity in tumor cells
