Heparinase selectively sheds heparan sulphate from the endothelial glycocalyx [PDF]
, 2008 A healthy vascular endothelium is coated by the endothelial glycocalyx. Its main constituents are transmembrane syndecans and bound heparan sulphates. This structure maintains the physiological endothelial permeability barrier and prevents leukocyte and ...

Systemic depletion of L-cyst(e)ine with cyst(e)inase increases reactive oxygen species and suppresses tumor growth [PDF]
Nature Medicine, 2016 Cancer cells experience higher oxidative stress from reactive oxygen species (ROS) than do non-malignant cells because of genetic alterations and abnormal growth; as a result, maintenance of the antioxidant glutathione (GSH) is essential for their survival and proliferation.

NFS1 undergoes positive selection in lung tumours and protects cells from ferroptosis [PDF]
, 2017 Environmental nutrient levels impact cancer cell metabolism, resulting in context-dependent gene essentiality. Here, using loss-of-function screening based on RNA interference, we show that environmental oxygen levels are a major driver of differential ...

GelMA/AgNWs Hydrogel Combined with Electrical Stimulation Effectively Promotes Skin Wound Healing
Advanced Materials Interfaces, Volume 12, Issue 14, July 25, 2025.The doped AgNWs in GelMA hydrogel prevent the wound from being infected and introduce the electrical field into the wound region. COMSOL simulation guides the introduced electric field to be conducive to promoting cell migration and proliferation. Thus, the GelMA/AgNWs hydrogel combined with ES effectively accelerated the healing process of skin wounds.
