RNase H-dependent DNA thresholder modulated by cancer marker concentration.

Threshold antisense oligonucleotide constructs were designed to cleave mRNA within different biomarker concentrations. The mRNA cleavage is activated by 2.6, 7.

Quantitative assessment of chaperone binding to amyloid aggregates identifies specificity of Hsp40 interaction with yeast prion fibrils.

Yeast self-perpetuating protein aggregates (yeast prions) provide a framework to investigate the interaction of misfolded proteins with the protein quality control machinery. The major component of this system that facilitates propagation of all known yeast amyloid prions is the Hsp104 chaperone that catalyzes fibril fragmentation. Overproduction of Hsp104 cures some yeast prions via a fragmentation-independent mechanism.
