Microvascular Health as a Key Determinant of Organismal Aging

open access: yesAdvanced Science, EarlyView.
This review spotlights the emerging field of vascular aging, providing a comprehensive and critical overview of the molecular processes and clinical manifestations of vascular dysfunction during aging. By combining basic angioscience concepts with a critical analysis of innovative pre‐clinical aging models and lifestyle interventions, it offers a ...

Telomeres cluster de novo before the initiation of synapsis: a three-dimensional spatial analysis of telomere positions before and during meiotic prophase. [PDF]

open access: yes, 1997
We have analyzed the progressive changes in the spatial distribution of telomeres during meiosis using three-dimensional, high resolution fluorescence microscopy.

High-resolution mapping of heteroduplex DNA formed during UV-induced and spontaneous mitotic recombination events in yeast. [PDF]

open access: yes, 2017
In yeast, DNA breaks are usually repaired by homologous recombination (HR). An early step for HR pathways is formation of a heteroduplex, in which a single-strand from the broken DNA molecule pairs with a strand derived from an intact DNA molecule.

C14ORF39/SIX6OS1 is a constituent of the synaptonemal complex and is essential for mouse fertility

open access: yesNature Communications, 2016
The synaptonemal complex is a meiosis-specific proteinaceous structure that supports homologous chromosome pairs during meiosis. Here, the authors show that SIX6OS1 (of previously unknown function) is part of the synaptonemal complex central element and ...

Treatment with Minicircle DNA Expressing a FGF23 Fragment in a Clinically relevant Mouse Model of X‐Linked Hypophosphatemic Rickets

open access: yesAdvanced Science, EarlyView.
The pathogenic role of PHEX isn't fully determined, and there is no radical cure for X‐linked hypophosphatemic rickets (XLHR). This study makes the first attempt to perform gene therapy using a minicircle DNA (MC‐DNA) vector expressing a fragment of FGF23 (amino acids 180‐251) in Phex‐T1349C mice and suggests MC‐DNA as a promisingly safe and effective ...

Meiotic chromosome movement: what’s lamin got to do with it?

open access: yesNucleus, 2019
Active meiotic chromosome movements are a universally conserved feature. They occur at the early stages of prophase of the first meiotic division and support the chromosome pairing process by (1) efficiently installing the synaptonemal complex between ...

Stabilized Ion Selectivity Corrects Activation Drift in Kalium Channelrhodopsins

open access: yesAdvanced Science, EarlyView.
As newly emerged optogenetic tools, potassium channelrhodopsins (KCRs) can drift from inhibition to activation during illumination as K⁺ selectivity declines. It is shown that both the absolute K⁺/Na⁺ permeability ratio and its stability over time govern this drift, identify KCR1‐C29D as a reliably inhibitory variant, and outline design principles for ...

HTGTS‐TCR‐Seq for Profiling of Mouse and Human T‐Cell Receptor α and β Gene Rearrangements and Diversity

open access: yesAdvanced Science, EarlyView.
HTGTS‐TCR‐seq is an efficient and cost‐effective method for profiling TCRα and TCRβ rearrangements using only a few primers. It captures both productive and nonproductive recombination events, minimizes primer bias, and reveals stage‐specific and age‐related repertoire changes in mice, as well as conserved features in human peripheral T cells ...
