Autonomous epithelial folding induced by an intracellular mechano-polarity feedback loop.
PLoS Computational Biology, 2021 Epithelial tissues form folded structures during embryonic development and organogenesis. Whereas substantial efforts have been devoted to identifying mechanical and biochemical mechanisms that induce folding, whether and how their interplay ...

Memristive excitable cellular automata [PDF]
, 2011 The memristor is a device whose resistance changes depending on the polarity and magnitude of a voltage applied to the device's terminals. We design a minimalistic model of a regular network of memristors using structurally-dynamic cellular automata ...

Cell Polarity Signaling: Focus on Polar Auxin Transport [PDF]
Molecular Plant, 2008 Polar auxin transport, which is required for the formation of auxin gradients and directional auxin flows that are critical for plant pattern formation, morphogenesis, and directional growth response to vectorial cues, is mediated by polarized sub-cellular distribution of PIN-FORMED Proteins (PINs, auxin efflux carriers), AUX1/AUX1-like proteins (auxin

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Development of electromagnetic tweezers for single-molecule energetics of kinesin
Biophysics and PhysicobiologyOptical tweezers have enabled single-molecule measurements of kinesin mechanics and energetics but face challenges for in vivo applications due to photothermal effects and refractive-index-dependent force calibration.

Attenuation of N-glycosylation causes polarity and adhesion defects in the C. elegans embryo [PDF]
, 2017 The C. elegans early embryo is highly polarized, requiring sequestration of cytoplasmic polarity factors at the plasma membrane. This compartmentalization aids asymmetric distribution of lipids and proteins, which is partially responsible for the fates ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Endocytic signaling in leaves and roots: same rules different players. [PDF]
, 2012 To take up proteins and other components required by the cell, cells internalize a portion of the plasma membrane (PM), which invaginates to form a closed vesicle within the cytoplasm in a process known as endocytosis. The major plant endocytic mechanism

Fly, 2011 Scientists like to consider themselves as especially objective, but, however hard we try we cannot be very different from everyone else. Like them we helplessly absorb our knowledge, our perspectives, our valuation of whether something is exciting or boring from those around us.
