A formative evaluation of 'Mind Matters: Overcoming Adversity and Building Resiliency' with Hispanic adolescents prior to and during Covid-19.

Youth living in poverty are more likely to experience cumulative stressors including multiple adverse childhood events. Further, the Covid-19 pandemic has disproportionality affected Hispanic youth and communities, leading to unprecedented levels of trauma. This research responded to a need for a youth resiliency-building program in an urban and impoverished area with a majority Hispanic population.

Inhibition of endothelial histone deacetylase 2 shifts endothelial-mesenchymal transitions in cerebral arteriovenous malformation models.

Cerebral arteriovenous malformations (AVMs) are the most common vascular malformations worldwide and the leading cause of hemorrhagic strokes that may result in crippling neurological deficits. Here, using recently generated mouse models, we uncovered that cerebral endothelial cells (ECs) acquired mesenchymal markers and caused vascular malformations. Interestingly, we found that limiting endothelial histone deacetylase 2 (HDAC2) prevented cerebral ECs from undergoing mesenchymal differentiation and reduced cerebral AVMs.

CDK1 inhibition reduces osteogenesis in endothelial cells in vascular calcification.

Vascular calcification is a severe complication of cardiovascular diseases. Previous studies demonstrated that endothelial lineage cells transitioned into osteoblast-like cells and contributed to vascular calcification. Here, we found that inhibition of cyclin-dependent kinase (CDK) prevented endothelial lineage cells from transitioning to osteoblast-like cells and reduced vascular calcification.
