Women account for almost two-thirds of Alzheimer's disease (AD) cases, yet evidence significantly less clinical benefit from recently deployed amyloid-lowering therapies. To close this disparity gap, there is an urgent need to identify biological drivers of sex differences in the manifestation and clinical response to AD therapeutics. A recent review of multi-omic studies of AD reported >75% of studies showed female-specific changes at the molecular level (vs.

Atherosclerotic lesions develop preferentially in arterial regions exposed to disturbed blood flow, where endothelial cells acquire an inflammatory phenotype. How disturbed flow induces endothelial cell inflammation is incompletely understood. Here we show that histone H3.

Objective: This study aimed to elucidate the role of pyruvate dehydrogenase kinase-1 (PDK1) in cervical cancer (CC) by investigating its impact on cell proliferation, migration, and epithelial-mesenchymal transition (EMT) under hypoxic conditions.
Methods: PDK1-silenced CC cell lines were established using lentiviral shRNA technology. Cell migration and invasion were assessed through scratch and Transwell assays, respectively.
Coordination of Focal Adhesion Nanoarchitecture and Dynamics in Mechanosensing for Cardiomyoblast Differentiation.

Focal adhesions (FAs) are force-bearing multiprotein complexes, whose nanoscale organization and signaling are essential for cell growth and differentiation. However, the specific organization of FA components to exert spatiotemporal activation of FA proteins for force sensing and transduction remains unclear. In this study, we unveil the intricacies of FA protein nanoarchitecture and that its dynamics are coordinated by a molecular scaffold protein, BNIP-2, to initiate downstream signal transduction for cardiomyoblast differentiation.

The aim of this study was to investigate the potential mechanism of Lu-Jiao Fang (LJF) inhibiting endothelial-to-mesenchymal transition (EndMT) in pressure overload-induced cardiac fibrosis. Pharmacokinetic behaviors of the ingredients of LJF were evaluated by LC-MS/MS analysis. Then putative pathways by which LJF regulates EndMT were analyzed by network pharmacology and verified in transverse aortic constriction-induced cardiac fibrosis rats.
