MiR126-Mediated Alteration of Vascular Integrity in Rett Syndrome
The study engineered 3D microvascular networks from Rett syndrome (RTT) patient‑derived iPS cells carrying MeCP2[R306C] or MeCP2[R168X] mutations and discovered markedly increased vascular permeability. Transcriptomic profiling linked this defect to up‑regulation of endothelial‑specific miR‑126‑3p, which suppresses tight‑junction regulators such as TEK and EDN‑1. Antisense knockdown of miR‑126‑3p partially restored ZO‑1 expression, normalized Ang/Tie2 signaling, and reduced permeability in the microfluidic model. These findings identify miR‑126‑3p as a direct MeCP2 target and a potential therapeutic lever for vascular dysfunction in RTT.
