| Expression pattern: |
UP |
| Associated gene: |
ZO-1, occludin, VCAM-1, ICAM-1, NF-kappaB, eNOS |
| Associated microRNA: |

| Biological function: |
preserves endothelial barrier integrity, stabilizes tight junctions, suppresses endothelial adhesion/inflammation, and improves microcirculatory perfusion during ECMO under pulsatile flow |
| Molecular mechanism: |
hsa_circ_0007367 upregulation is required for pulsatility-induced ZO-1/occludin upregulation and mediates suppression of NF-kappaB signaling and modulation of eNOS activity |

| Description: |
In a cardiac-arrest canine ECMO model and endothelial cells exposed to pulsatile flow, hsa_circ_0007367 (circUBAP2) is upregulated and is required to maintain endothelial barrier integrity. Its upregulation supports ZO-1/occludin expression and contributes to anti-inflammatory effects involving eNOS modulation and NF-kappaB inhibition, thereby improving microcirculatory perfusion during ECMO. |
