Serum hepcidin is associated with retinopathy of prematurity and modulates oxidative stress and angiogenic responses in retinal microvascular endothelial cells
To investigate the effects of hepcidin on human retinal microvascular endothelial cells (hRMECs) under oxidative stress and assess its translational potential in ROP, highlighting its significance in mitigating oxidative injury.
Key Findings:
Infants with ROP had lower gestational age and birth weight than controls.
Serum hepcidin-related signals were numerically lower in ROP infants, but no significant stage-dependent decrease was observed.
Hypoxia altered hRMEC viability, upregulated VEGFA and HIF-1α mRNA, increased secreted VEGFA, and promoted ROS accumulation.
The study provides preliminary evidence supporting a role of hepcidin in ROP, indicating its potential to mitigate oxidative stress and abnormal angiogenesis in retinal endothelial cells, warranting further investigation.
Limitations:
Clinical findings are exploratory and limited by assay quantification range, emphasizing the need for larger studies.
The study does not establish a direct causal relationship between hepcidin levels and ROP, highlighting the need for further research.
Conclusion:
Hepcidin may represent a biologically relevant pathway and potential candidate for further biomarker and therapeutic research in ROP, necessitating additional studies to validate these findings.
