Mechanozyme: An Artificial Enzyme With a Mechanophore Framework

Advanced Science, EarlyView.
Mechanical destabilization of a G‐quadruplex mechanophore in a DNAzyme markedly boosts its catalytic activity, demonstrating “mechanozymes” as artificial enzymes whose functions are modulated by mechanical stress exerted by ultrasonication. This mechanozyme principle is broadly applicable to control biomolecular activities.

Renal fibroblasts are involved in fibrogenic changes in kidney fibrosis associated with dysfunctional telomeres

Experimental and Molecular Medicine
Tubulointerstitial fibrosis associated with chronic kidney disease (CKD) represents a global health care problem. We previously reported that short and dysfunctional telomeres lead to interstitial renal fibrosis; however, the cell-of-origin of kidney ...

Shorter juvenile telomere length is associated with higher survival to spawning in migratory Atlantic salmon [PDF]

, 2017
The risk of mortality associated with a long-distance migration will depend on an animal's physiological state, as well as the prevailing ecological conditions.

Mechanically Triggered DNA Nanovehicles for Targeted Dual‐Drug Cancer Therapy

Advanced Science, EarlyView.
A mechanically triggered DNA nanovehicle is introduced that co‐releases two anticancer drugs in response to integrin‐mediated cellular forces. Cholesterol‐anchored DNA assemblies undergo force‐induced unfolding at cell–cell junctions, enabling selective, localized dual‐drug activation in cancer cells while minimizing off‐target toxicity in low‐tension ...

TALEN Gene Knockouts Reveal No Requirement for the Conserved Human Shelterin Protein Rap1 in Telomere Protection and Length Regulation

Cell Reports, 2014
The conserved protein Rap1 functions at telomeres in fungi, protozoa, and vertebrates. Like yeast Rap1, human Rap1 has been implicated in telomere length regulation and repression of nonhomologous end-joining (NHEJ) at telomeres. However, mouse telomeres

Mapping of cell nuclei based on contour warping [PDF]

, 2010
The dynamics of genome regions are associated to the functional or dysfunctional behaviour of the human cell. In order to study these dynamics it is necessary to remove all perturbations coming from movement and deformation of the nucleus, i.e.

Short-term inhibition of TERT induces telomere length-independent cell cycle arrest and apoptotic response in EBV-immortalized and transformed B cells [PDF]

, 2016
open7siBesides its canonical role in stabilizing telomeres, telomerase reverse transcriptase (TERT) may promote tumorigenesis through extra-telomeric functions.

Reprogramming Antitumor Immunity: NK Cell Strategies to Navigate the Immunosuppressive Tumor Microenvironment

Advanced Science, EarlyView.
ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.

Double-strand break repair and homologous recombination in Schizosaccharomyces pombe [PDF]

, 2006
In recent years our understanding of double strand break repair and homologous recombination in Schizosaccharomyces pombe has increased significantly, and the identification of novel pathways and genes with homologues in higher eukaryotes has increased ...

Telomeres in Space

Aging Cell
ABSTRACTRecent studies have reported that the spaceflight environment lengthens leukocyte telomeres. We propose that this baffling finding reflects changes in the composition of leukocyte subsets rather than an actual increase in telomere length within individual leukocytes.
