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

FEBS 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.

Theory of High-Force DNA Stretching and Overstretching [PDF]

, 2002
Single molecule experiments on single- and double stranded DNA have sparked a renewed interest in the force-extension of polymers. The extensible Freely Jointed Chain (FJC) model is frequently invoked to explain the observed behavior of single-stranded ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

DNA intercalation and cleavage of an antitumor antibiotic dynemicin that contains anthracycline and enediyne cores [PDF]

, 1990
Dynemicin is a hybrid containing anthraquinone and enediyne cores, which contribute to binding and cleavage of DNA, respectively. DNA strand scission by the antitumor antibiotic is significantly enhanced by the addition of NADPH or thiol compounds.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

AUTOANTIBODIES TO DNA IN BLOOD SERUM OF PATIENTS WITH HEMORRHAGIC FEVER WITH RENAL SYNDROME

Медицинская иммунология, 2014
. The levels of autoantibodies (AAbs) to double- and single-stranded DNA were studied in blood serum of sixty-one patients with hemorrhagic fever complicated by renal syndrome (HFRS), and twenty-five healthy persons using ELISA technique.

Single Strand Annealing and ATP-independent Strand Exchange Activities of Yeast and Human DNA2: possible role in Ozaki fragment maturation [PDF]

, 2006
The Dna2 protein is a multifunctional enzyme with 5'-3' DNA helicase, DNA-dependent ATPase, 3' exo/endonuclease, and 5' exo/endonuclease. The enzyme is highly specific for structures containing single-stranded flaps adjacent to duplex regions.

Transferrin-polycation conjugates as carriers for DNA uptake into cells. [PDF]

, 1990
We have developed a high-efficiency nucleic acid delivery system that uses receptor-mediated endocytosis to carry DNA macromolecules into cells. We accomplished this by conjugating the iron-transport protein transferrin to polycations that bind nucleic ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Ultraaccurate genome sequencing and haplotyping of single human cells. [PDF]

, 2017
Accurate detection of variants and long-range haplotypes in genomes of single human cells remains very challenging. Common approaches require extensive in vitro amplification of genomes of individual cells using DNA polymerases and high-throughput short ...
