Protein misfolding and aggregation cause a large number of neurodegenerative diseases in humans due to (i) gain of function as observed in Alzheimer's disease, Huntington's disease, Parkinson's disease, and Prion's disease or (ii) loss of function as observed in cystic fibrosis and alpha1-antitrypsin deficiency. These misfolded proteins could either lead to the formation of harmful amyloids tha...

molecular chaperones or amyloid-binding compounds?  perspective on their application as possible therapeutic agents in reduction of cytotoxicity of amyloid oligomers

(1) Background: Congenital factor (F) VII deficiency is caused by mutations in the F7 gene. Patients with modest differences FVII levels may display large clinical severity. The variant p.A354V-p.P464Hfs associated reduced antigen and activity. aim of study was to investigate manifestation this underlying molecular mechanisms. (2) Methods: Analyses were conducted 37 homozygous patients. recombi...

Maintenance of cellular homeostasis is regulated by the molecular chaperones. Under pathogenic conditions, aberrant proteins are triaged by the chaperone network. These aberrant proteins, known as "clients," have major roles in the pathogenesis of numerous neurological disorders, including tau in Alzheimer's disease, α-synuclein and LRRK2 in Parkinson's disease, SOD-1, TDP-43 and FUS in amyotro...

DnaK is a molecular chaperone of Escherichia coli that belongs to a family of conserved 70-kDa heat shock proteins. The Hsp70 chaperones are well known for their crucial roles in regulating protein homeostasis, preventing protein aggregation, and directing subcellular traffic. Given the complexity of functions, a chemical method for controlling the activities of these chaperones might provide a...

Primary hyperoxaluria type 1 (PH1) is an inborn error of metabolism resulting from a deficiency of alanine:glyoxylate aminotransferase (AGXT; EC 2.6.1.44). Most of the PH1 alleles detected in the Canary Islands carry the Ile-244 --> Thr (I244T) mutation in the AGXT gene, with 14 of 16 patients homozygous for this mutation. Four polymorphisms within AGXT and regional microsatellites also were sh...
