MSN inhibition reversed LPS-induced vascular hyperpermeability and recovered the MLC expression in HMECs via regulating the Rock1 activity.(a) RT-qPCR and (b) Western Blotting analyses of the efficacy of MSN silencing in HMECs, and the semiquantification for MSN silencing was shown in (c). (d) MSN silencing abrogated the LPS-induced vascular hyperpermeability in monolayer HMECs, determined by the FITC-dextran-based barrier integrity assay. (e) Protein interaction analysis showed that MSN was closely related to the RhoA/Rock pathway. (f) Coimmunoprecipitation analyses of the interaction between p-MSN and Rock1 in HMECs treated with or without LPS (24 h). (g) MSN silencing mitigated the LPS-increased MSN and MLC phosphorylation and Rock1 expression in HMECs, and the semiquantification for WB was shown in (h). , , and .
