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.

Pros and cons of a prion-like pathogenesis in Parkinson's disease [PDF]

, 2011
Background: Parkinson's disease (PD) is a slowly progressive neurodegenerative disorder which affects widespread areas of the brainstem, basal ganglia and cerebral cortex.

Prion Protein Transgenes and the Neuropathology in Prion Diseases

Brain Pathology, 1995
The concept that prions are novel pathogens which are different from both viroids and viruses has received increasing support from many avenues of investigation over the past decade. Enriching fractions from Syrian hamster (SHa) brain for scrapie prion infectivity led to the discovery of the prion protein (PrP).

Prion protein E219K polymorphism: from the discovery of the KANNO blood group to interventions for human prion disease

Frontiers in Neurology
KANNO is a new human blood group that was recently discovered. The KANNO antigen shares the PRNP gene with the prion protein and the prion protein E219K polymorphism determines the presence or absence of the KANNO antigen and the development of anti ...

Absence of single nucleotide polymorphisms (SNPs) in the open reading frame (ORF) of the prion protein gene (PRNP) in a large sampling of various chicken breeds

BMC Genomics, 2019
Background Prion diseases are zoonotic diseases with a broad infection spectrum among mammalian hosts and are caused by the misfolded prion protein (PrPSc) derived from the normal prion protein (PrPC), which encodes the prion protein gene (PRNP ...

Treatment with KCL‐286, a first‐in‐class retinoic acid receptor‐β (RARβ) agonist, ameliorates neuronal DNA damage and inflammation in a mouse model of Alzheimer's disease

FEBS Open Bio, EarlyView.
Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Effect of enzymatic deimination on the conformation of recombinant prion protein [PDF]

, 2009
Deimination is the post-translational conversion of arginine residues to citrulline. It has been implicated as a causative factor in autoimmune diseases such as multiple sclerosis and rheumatoid arthritis and more recently, as a marker of ...

Glycosylation and prion protein

Current Opinion in Structural Biology, 2002
Recent advances have elucidated the detailed glycosylation of the prion protein and highlighted the size of the sugars, which shield large areas of the protein and confer some conformational stability on the normal cellular form. The reliability of SDS-PAGE banding patterns of different "glycoforms" as a diagnostics tool has been discussed.

Thermodynamic Stabilization of the Folded Domain of Prion Protein Inhibits Prion Infection in Vivo

Cell Reports, 2013
Prion diseases, or transmissible spongiform encephalopathies (TSEs), are associated with the conformational conversion of the cellular prion protein, PrPC, into a protease-resistant form, PrPSc.

Adenosine triphosphate as a modulator of protein interactions and stability

FEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...
