Aromatase Inhibitors and the Risk of Cardiovascular Outcomes in Women With Breast Cancer: A Population-Based Cohort Study.
CONCLUSIONS: In this population-based study, aromatase inhibitors were associated with increased risks of heart failure and cardiovascular mortality compared with tamoxifen. There were also trends toward increased risks, although nonsignificant, of myocardial infarction and ischemic stroke. The increased risk of cardiovascular events associated with aromatase inhibitors should be balanced with their favorable clinical benefits compared with tamoxifen.

Endothelial Cell-Specific Inactivation of TSPAN12 (Tetraspanin 12) Reveals Pathological Consequences of Barrier Defects in an Otherwise Intact Vasculature.
Conclusions- This study establishes mice with late endothelial cell-specific loss of Tspan12 as a model to study pathological consequences of BRB impairment in an otherwise intact vasculature. PMID: 30354230 [PubMed - in process]

Conditional knockout of activin like kinase-1 (ALK-1) leads to heart failure without maladaptive remodeling
AbstractActivin like kinase-1 (AlK-1) mediates signaling via the transforming growth factor beta (TGF β) family of ligands. AlK-1 activity promotes endothelial proliferation and migration. Reduced AlK-1 activity is associated with arteriovenous malformations. No studies have examined the effect of global AlK-1 deletion on indices of cardiac remodeling. We hypothesized that reduced levels of AlK-1 p romote maladaptive cardiac remodeling. To test this hypothesis, we employed AlK-1 conditional knockout mice (cKO) harboring the ROSA26-CreER knock-in allele, whereby a single dose of intraperitoneal tamoxifen triggered ubiquito...

Endothelial β-Catenin Signaling Is Required for Maintaining Adult Blood-Brain Barrier Integrity and CNS Homeostasis.
CONCLUSIONS: -These results demonstrate the prerequisite role of endothelial β-catenin in maintaining the integrity of adult BBB. The results suggest that BBB dysfunction secondary to defective β-catenin transcription activity is a key pathogenic factor in hemorrhagic stroke, seizure activity and CNS inflammation.

Vascular Stat3 Promotes Angiogenesis and Neuroplasticity Long-Term After Stroke.
CONCLUSIONS: -Endothelial Stat3 regulates angiogenesis, axon growth and ECM-remodeling and is essential for long-term recovery after stroke. It might serve as a potent target for stroke treatment after the acute phase by fostering angiogenesis and neuroregeneration. PMID: 25794850 [PubMed - as supplied by publisher]

Association of Tamoxifen Use and Reduced Cardiovascular Events Among Asian Females With Breast Cancer.
Conclusions: In Asian female breast cancer patients, tamoxifen use was associated with reduced risks of AMI, ischemic, hemorrhagic stroke and total cardiovascular events. PMID: 24107360 [PubMed - as supplied by publisher]
