Ephrin type-B receptor 4 messenger RNA (EPHB4 mRNA) (EPHB4 mRNA)

Ephrin type-B receptor 4 (EPHB4) mRNA is the messenger RNA transcript that encodes the EPHB4 protein, a member of the receptor tyrosine kinase (RTK) family [UniProt: P54760]. This mRNA is a critical component of the EPH/Ephrin signaling system, which is the largest subfamily of RTKs and is essential for embryonic development, particularly in the cardiovascular and nervous systems [NCBI: 2050]. EPHB4 mRNA expression is vital for the differentiation of venous endothelial cells and the formation of mature vascular networks through its interaction with the ligand Ephrin-B2 [PubMed: 19440285]. In oncology, the overexpression of EPHB4 mRNA has been documented in numerous solid tumors, including breast, lung, and prostate cancers, where it promotes tumor cell survival, migration, and neoangiogenesis [PubMed: 16432173]. Therapeutic targeting of EPHB4 mRNA, primarily through RNA interference (RNAi) or antisense oligonucleotides (ASOs), aims to downregulate the production of the EPHB4 protein to inhibit these oncogenic processes [PubMed: 21636688]. While most clinical-stage EPHB4 inhibitors target the protein directly, mRNA-directed strategies are being explored to achieve more comprehensive silencing of the receptor's signaling functions [PubMed: 25653148].
