ERM Inhibition Confers Ferroptosis Resistance through ROS‐Induced NRF2 Signaling

Advanced Science, EarlyView.
ERM inhibition disrupts ERM‐actin interactions, elevating ROS and triggering KEAP1 degradation, which stabilizes and activates NRF2. Nuclear NRF2 induces cytoprotective genes, notably HMOX1, enhancing redox buffering and suppressing lipid peroxidation to resist erastin‐induced ferroptosis.

Dissolved organic carbon fluxes by seagrass meadows and macroalgal beds

Frontiers in Marine Science, 2014
Estimates of dissolved organic carbon (DOC) release by marine macrophyte communities (seagrass meadows and macroalgal beds) based on in situ benthic chambers from published and unpublished are compiled in this study.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

Advanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Distribution and Transport of Antarctic Winter Water Biogeochemical Properties

Geophysical Research Letters
Antarctic Winter Water (WW) forms in the surface mixed layer south of the Antarctic Polar Front and moves subsurface on seasonal timescales. Here, we use biogeochemical‐Argo float data to investigate the circumpolar patterns of the biogeochemical ...

Engineered GM1 Intersects Between Mitochondrial and Synaptic Pathways to Ameliorate ALS Pathology

Advanced Science, EarlyView.
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease driven by genetic and molecular disruptions affecting energy balance, protein homeostasis, and stress responses in nerve cells. Studies using human and rodent models identified convergent defects in mitochondria and synaptic function.

Phytoplankton physiology and functional traits under artificial upwelling with varying Si:N

Frontiers in Marine Science
IntroductionArtificial upwelling has been discussed as a nature-based solution to fertilize currently unproductive areas of the ocean to enhance food web productivity and atmospheric CO2 sequestration. The efficacy of this approach may be closely tied to

Coincident Fluorescence‐Burst Analysis of Actin Cargo Molecules in Secreted Single Diffusing Extracellular Vesicles From Human Induced Pluripotent Stem Cells

Advanced Science, EarlyView.
This study presents a two‐color FCCS and coincident‐burst analysis platform to quantify actin cargo in dual‐labeled EVs secreted from hiPSCs. The approach tracks secretion dynamics, confirms actin loading, and measures EV size and cargo number, offering insights into cytoskeletal disruption and neuronal differentiation relevant to neurodegenerative ...
