Goreisan attenuates cardiac hypertrophy and diastolic dysfunction in heart failure with preserved ejection fraction induced by HFD/L-NAME via regulation of ICAT-β-catenin/ERK axis

Goreisan, a traditional herbal formulation, has shown promise in alleviating cardiac hypertrophy and diastolic dysfunction associated with heart failure with preserved ejection fraction (HFpEF). The study identifies its mechanism of action through the regulation of the ICAT-β-catenin/ERK signaling pathway. This research highlights the increasing global prevalence of HFpEF and positions Goreisan as a potential novel therapeutic option in cardiovascular treatment, warranting further clinical investigation.

Nesfatin-1 ameliorates blood-brain barrier dysfunction in Alzheimer’s disease by targeting VEGF-R1 and reducing cellular senescence in brain vascular endothelial cells

Nesfatin-1 (NF-1) has been shown to improve blood-brain barrier (BBB) dysfunction in Alzheimer's disease (AD) by targeting VEGF-R1 and reducing cellular senescence in brain endothelial cells. The study found that NF-1 treatment restored the expression of tight junction proteins and mitigated the permeability increase induced by oligomerized Aβ1-42. In transgenic AD mouse models, NF-1 administration decreased VEGF-R1 levels, suggesting a protective role for NF-1 in maintaining BBB integrity and offering a potential therapeutic avenue for AD.
