Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Apoferritin Amyloid-Fibril Directed the In Situ Assembly and/or Synthesis of Optical and Magnetic Nanoparticles

open access: yesNanomaterials, 2021
The coupling of proteins that can assemble, recognise or mineralise specific inorganic species is a promising strategy for the synthesis of nanoscale materials with a controllable morphology and functionality.

Stop-and-go kinetics in amyloid fibrillation [PDF]

open access: yes, 2009
Many human diseases are associated with protein aggregation and fibrillation. Using glucagon as a model system for protein fibrillation we show that fibrils grow in an intermittent fashion, with periods of growth followed by long pauses. Remarkably, even

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Cryo-EM structure and polymorphism of Aβ amyloid fibrils purified from Alzheimer’s brain tissue

open access: yesNature Communications, 2019
Alzheimer’s disease is characterised by the deposition of Aβ amyloid fibrils and tau protein neurofibrillary tangles. Here the authors use cryo-EM to structurally characterise brain derived Aβ amyloid fibrils and find that they are polymorphic and right ...

Fibronectin: Molecular Structure, Fibrillar Structure and Mechanochemical Signaling

open access: yesCells, 2021
The extracellular matrix (ECM) plays a key role as both structural scaffold and regulator of cell signal transduction in tissues. In times of ECM assembly and turnover, cells upregulate assembly of the ECM protein, fibronectin (FN).

Structure-based inhibitors of amyloid beta core suggest a common interface with tau. [PDF]

open access: yes, 2019
Alzheimer's disease (AD) pathology is characterized by plaques of amyloid beta (Aβ) and neurofibrillary tangles of tau. Aβ aggregation is thought to occur at early stages of the disease, and ultimately gives way to the formation of tau tangles which ...

Collagens - structure, function and biosynthesis. [PDF]

open access: yes, 2003
The extracellular matrix represents a complex alloy of variable members of diverse protein families defining structural integrity and various physiological functions.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Co-factor-free aggregation of tau into seeding-competent RNA-sequestering amyloid fibrils

open access: yesNature Communications, 2021
The authors present a method for the conversion of full-length tau protein into seeding-competent amyloid fibrils without heparin or other negatively charged co-factors, which could be useful for studying the effects of post-translational modifications ...
