Acacetin and Chrysin, Two Polyphenolic Compounds, Alleviate Telomeric Position Effect in Human Cells
Molecular Therapy: Nucleic Acids, 2013 We took advantage of the ability of human telomeres to silence neighboring genes (telomere position effect or TPE) to design a high-throughput screening assay for drugs altering telomeres.

Chemistry – A European Journal, EarlyView.G‐quadruplex (G4) folding in DNA is inhibitory to AP endonuclease, although the protein still binds well to G4s. Curiously, partially folded G‐rich sequences, possibly transient hairpins, containing AP are very good substrates for cleavage by APE1. Herein, the enzyme activity and G4 folding are studied in single‐stranded vs. duplex contexts.

Modulation of telomere protection by the PI3K/AKT pathway
Nature Communications, 2017 Regulation of telomeres and the insulin/PI3K pathway both have roles in aging and cancer development but have not been functionally linked. Here the authors demonstrate that PI3K, via downstream targets, regulates TRF1 via phosphorylation.

Highly Aggressive Metastatic Melanoma Cells Unable to Maintain Telomere Length
Cell Reports, 2017 Summary: Unlimited replicative potential is one of the hallmarks of cancer cells. In melanoma, hTERT (telomerase reverse transcriptase) is frequently overexpressed because of activating mutations in its promoter, suggesting that telomerase is necessary ...

Cytoskeleton, EarlyView.ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Cytoskeleton, EarlyView.ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

PharmVar GeneFocus: NAT2—Genetic Variation and Updated Nomenclature
Clinical Pharmacology &Therapeutics, EarlyView.The Pharmacogene Variation Consortium (PharmVar) provides nomenclature for the highly polymorphic human N‐acetyltransferase 2 (NAT2) gene. NAT2 metabolizes several clinically used drugs including isoniazid, hydralazine, amifampridine, procainamide, and sulfonamides such as dapsone, and also some highly carcinogenic arylamines.
