EphA2 Gene Editing    

Ephrin type-A receptor 2 (EphA2) is a 130 kDa glycoprotein receptor and belongs to the largest EPH family receptor tyrosine kinases. The EphA2 protein structure has an intracellular kinase domain, and an extracellular domain with an Ephrin binding domain and two fibronectin type III repeats. Binding to Eph triggers a series of intracellular signals including RAS/MAPK, FAK/SRC, ABL, RHO/RAC/CDC42, and PI3K/AKT/mTOR, and regulates migration, proliferation, integrin-mediated adhesion and differentiation of cells (Figure 1).

EphA2 signaling is involved in the regulation of many development-related events, especially in neurodevelopment. EphA2 is also involved in the regulation of lens formation, and mutations in the EphA2 gene are responsible for hereditary cataracts. In addition, EphA2 plays an important regulatory role in malignant transformation, angiogenesis, and metastasis of normal cells, and EphA2 is overexpressed in a variety of cancer cells, including glioblastoma, colorectal cancer, gastric cancer, breast cancer, thyroid cancer, ovarian cancer, endometrial cancer, cervical cancer, pancreatic cancer, prostate cancer, melanoma, bladder cancer, kidney cancer, lung cancer, and liver cancer. In cancer therapy, EphA2 may affect prognosis due to its ability to promote cell migration and invasion. EphA2 may provide new clues to better molecular understanding of neurodegenerative diseases and cancer development, and further research on EphA2 as a new prognostic biomarker and the therapeutic target will provide new support for cancer treatment.
