RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

β-microglobulin amyloid fibril-induced membrane disruption is enhanced by endosomal lipids and acidic pH [PDF]

, 2014
Although the molecular mechanisms underlying the pathology of amyloidoses are not well understood, the interaction between amyloid proteins and cell membranes is thought to play a role in several amyloid diseases. Amyloid fibrils of β-microglobulin (βm),

Misfolded proteins share a common capacity in disrupting LLPS organizing membrane-less organelles [PDF]

, 2018
Abstract Profilin-1 mutants cause ALS by gain of toxicity but the underlying mechanism remains unknown. Here we showed that three PFN1 mutants have differential capacity in disrupting dynamics of FUS liquid droplets underlying the formation of stress granules (SGs).

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

The road not taken: Less traveled roads from the TGN to the plasma membrane [PDF]

, 2015
: The trans-Golgi network functions in the distribution of cargo into different transport vesicles that are destined to endosomes, lysosomes and the plasma membrane. Over the years, it has become clear that more than one transport pathway promotes plasma

In Vivo Formation of Vacuolated Multi-phase Compartments Lacking Membranes

Cell Reports, 2016
Eukaryotic cells contain membrane-less organelles, including nucleoli and stress granules, that behave like liquid droplets. Such endogenous condensates often have internal substructure, but how this is established in the absence of membrane ...

Tunable multiphase dynamics of arginine and lysine liquid condensates

Nature Communications, 2020
The design principles underlying biomolecular phase separation of membrane-less organelles remain poorly understood. Using model homopolymers, Fisher et al.

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Behavior control of membrane-less protein liquid condensates with metal ion-induced phase separation

Nature Communications, 2020
Mimetic membrane-less organelles are of interest for the range of biochemical processes which can be spatio-temporally organized using them. Here, the authors report on a protein condensate system formed by metal ion induced clustering and demonstrate ...
