This PDF file includes:

  • Fig. S1. Effect of different STIM1 siRNAs on the thrombin-mediated decrease in TER in HUVECs.
  • Fig. S2. STIM1 knockdown does not affect basal endothelial monolayer resistance.
  • Fig. S3. STIM1 knockdown, but not Orai1 knockdown, inhibited the decrease in TER of HDMECs in response to thrombin.
  • Fig. S4. Low concentrations of Gd3+ completely abrogate Ca2+ entry in response to thrombin in HDMECs.
  • Fig. S5. The effects of thapsigargin on TER are distinct from those of thrombin and are SOCE-independent.
  • Fig. S6. STIM1 knockdown in HUVECs increased basal phosphorylation of FAK and paxillin.
  • Fig. S7. Effectiveness of TRPC1, TRPC4, or TRPC6 knockdown in HUVECs.
  • Fig. S8. MLCK knockdown in HUVECs and HDMECs has no effect on the thrombin-induced decrease in TER.
  • Table S1. Antibodies used in the study with corresponding dilutions.
  • Table S2. Sequences of the primers and siRNA sequences used throughout the study.
