We show that ephrinB2 expression by endothelial cells and EphB4 expression by cancer cells have similar effects on tumor vasculature, despite sometimes opposite effects on tumor growth. This implicates a cancer-cell-intrinsic effect of EphB4 forward signaling and not angiogenesis in EphB4's action as a tumor suppressor.
Our results suggest that circEfnb2 deficiency may decrease OGD/R-induced HT22 cell damage by modulating the miR-202-5p/TRAF3 axis. This explanation may provide a new direction for cerebral infarction potential therapeutic targets.
Complementary analysis of MM patient data revealed that increased EFNB2 expression is associated with adverse-risk disease and decreased survival. This study suggests that EFNB2 reverse signaling controls MM pathogenesis and can be therapeutically targeted to improve MM outcomes.
Thus, EFNB2 has potential to be theranostic marker for CTX resistance. The online version contains supplementary material available at 10.1007/s12070-023-03739-9.
EphrinB2 is expressed in approximately half of RCC cases. EphrinB2 expression in the early stage cancer might indicate its induction as an early event.
In sum, pulmonary vascular remodeling was dependent on ephrin-B2-induced Eph receptor (erythropoietin-producing hepatocellular carcinoma receptor) forward signaling in SMC, while EphB4 receptor activity was necessary for RhoA expression in SMC, interaction with endothelial cells and vasoconstrictive components of pulmonary hypertension.

Inhibition of the EFNB2/EPHB4 axis markedly prolonged the survival time of BALB/c nude mice with CRC LM with a high cholesterol diet. These findings revealed a key step in the regulation of cholesterol uptake by EFNB2/EPHB4 axis and its tumor-promoting role in CRC LM.
Phase II clinical trials using TROP2-directed antibody-drug conjugates and a combination of pembrolizumab with sEphB4-HAS, a decoy receptor for ephrin B2, are ongoing for urothelial carcinoma... Expression of TROP2 and ephrin B2 in BCVH potentially expands the therapeutic possibilities for these patients with limited treatment options. Clinical trials to investigate the efficacy of these novel treatments on BCVH is warranted. M.A.
