Inhibition of Akt and NFκB were administrated by applying LY294002 (LY) and PDTC, respectively. CXCR4 expression in eELCs was inhibited by both LY and PDTC (a). The nuclear translocation of NFκB was inhibited by PDTC treatment under hypoxia and was totally abolished when treating with LY in both normoxia and hypoxia conditions (b). The increase of wound closure in eELCs under hypoxia (DFO) was inhibited by LY and almost abolished by PDTC treatment (c). The increase of transmigration ability in hypoxic eELCs was also inhibited by either LY or PDTC inhibitor (d). Scale bar: (c) 200 μm; (d) 400 μm. *Significant from eELCs under regular culture condition (without DFO), p < 0.05; #significant from eELCs under hypoxia (DFO, 50 μM), p < 0.05.
