Uptake and cytotoxicity of citrate-coated gold nanospheres : comparative studies on human endothelial and epithelial cells [PDF]

, 2012
The use of gold nanoparticles (AuNPs) for diagnostic applications and for drug and gene-delivery is currently under intensive investigation. For such applications, biocompatibility and the absence of cytotoxicity of AuNPs is essential. Although generally

Over-expression of MAP kinase phosphatase-2 enhances adhesion molecule expression and protects against apoptosis in human endothelial cells [PDF]

, 2010
In this study we used adenovirus infection to overexpress the dual specific phosphatase, MAP kinase phosphatase-2 (MKP-2), in human umbilical vein endothelial cells and examined inflammatory protein expression and apoptosis, two key features of ...

HMGCR‐Driven Cholesterol Metabolism Promotes Osteoarthritis Progression by Accelerating Synovial Fibroblast Senescence

Advanced Science, Volume 13, Issue 55, 5 October 2026.
In the pathological context of osteoarthritis (OA), the phosphorylation of AKT1 at Ser473 enhances its binding to Lys140 of Insig1, which facilitates the formation of AKT1–Insig1 complex. Subsequently, the activation of AKT1 promotes the phosphorylation of Insig1 at Ser189, potentially enhancing the dissociation of Insig1 from sterol regulatory element‑

Directed Differentiation of Human Pluripotent Stem Cells towards Corneal Endothelial-Like Cells under Defined Conditions

, 2021
The most crucial function of corneal endothelial cells (CEnCs) is to maintain optical transparency by transporting excess fluid out of stroma. Unfortunately, CEnCs are not able to proliferate in vivo in the case of trauma or dystrophy.

Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

Zeb2 Controls Retinal Physiological and Pathological Angiogenesis by Regulating Astrocyte Proliferation and Differentiation

Cell Proliferation, Volume 59, Issue 10, October 2026.
During development, the oxygen‐sensitive transcription factor Zeb2 restrains astrocyte proliferation and maturation to ensure balanced retinal angiogenesis. In disease, it promotes the neurotoxic A1 astrocyte phenotype and inflammation, thereby promoting reparative revascularization over pathological neovascularization.

Nucleic Acids as Emerging Regulators of Calcium Phosphate Biomineralization

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
Calcium phosphate biomineralization has traditionally been considered a protein‐regulated process. This review highlights the emerging role of nucleic acids, which interact with mineral phases through adsorption, coprecipitation, and templating, thereby influencing crystal nucleation and growth.

Vascular endothelial growth factor production and regulation in rodent and human pituitary tumor cells in vitro [PDF]

, 2001
Angiogenesis, the formation of a new blood supply, is an essential step in tumorigenesis. Although vascular endothelial growth factor (VEGF) is known to be a very potent angiogenic factor in most solid tumors, little is known about its production and ...
