Ca2+-dependent phosphatidylserine synthesis in immature and mature starfish oocytes. [PDF]

open access: yes, 2003
We found that in starfish oocytes two different enzymes, phosphatidylserine synthase-1 (PSS1) and -2 (PSS2), which synthesize phosphatidylserine by a base-exchange reaction, are present.

In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action

open access: yesPest Management Science, EarlyView.
In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action. Cinmethylin inhibits FATs, disrupting eukaryotic de novo lipid biosynthesis and causing defects in cell division, elongation and integrity. We confirm FATs as the primary site of action in planta.

Responsive nanoheterojunctions for built‐in electric field‐promoted cascade tumor targeting and cuproptosis‐based therapy

open access: yesResponsive Materials, EarlyView.
Nanoheterojunctions have been synthesized as responsive biomaterials for cascade targeting of tumor cells and mitochondria, ROS‐mediated apoptosis and Cu‐promoted cuproptosis. And drug‐device‐field integration as an advanced paradigm of tumor treatment was employed for photo‐triggered tumor cell elimination in vitro and lesion eradication in vivo ...

Osmotic Remodeling of Extracellular Vesicles for Precision Nanomedicine

open access: yesSmall, EarlyView.
Hypotonic lysis in bidistilled water is used to remodel B lymphocyte–derived extracellular vesicles into cargo‐depleted, structurally preserved nanovesicles. The process reduces intraluminal proteins and nucleic acids, reshapes membrane composition, and enhances tumor‐cell uptake in vitro, while allowing proof‐of‐concept reloading with exogenous agents,
