MiR-206 Promotes Extracellular Matrix Accumulation and Relieves Infantile Hemangioma through Targeted Inhibition of DNMT3A

Researchers found that miR-206 could promote ECM accumulation through targeted inhibition of DNA Methyltransferase 3A (DNMT3A), inhibiting the malignant development of hemangioma endothelial cells and relieving infantile hemangioma.

Mineralocorticoid and Estrogen Receptors in Endothelial Cells Coordinately Regulate Microvascular Function in Obese Female Mice

Estrogen receptor α (ERα) can oppose mineralocorticoid receptor (MR) function, therefore, scientists hypothesized that ERα mediates the benefits of endothelial MR deficiency.
