Fig. 9. Schematic mechanism of EphB1 cis and trans signaling controlling the cell dormancy and reactivation after chemotherapy.

A In the dormant EMT cells which showed disrupted cell-cell contacts, ligand-independent EphB1 promoted entry of lung cancer cells into G0-G1 phase of cell cycle through activating p-p38 and downregulating E-cadherin; B Interaction of cell-contact-mediated cis- and trans-signalings. Disruption of cis-signaling activates trans-signaling; C Disruption of trans-signaling inhibits EphB1 forward signaling; D In the state of MET, in which cell-cell adhesion was recovered, interactions of EphB1 and ligand EphrinB2 in trans promoted the stemness of cancer cells through upregulating Nanog and Sox2.
