Advanced Science, EarlyView.IGFBP4 is upregulated in granulosa cells of aged ovaries across monkeys, mice, and humans. It inhibits YAP signaling, thereby suppressing cell proliferation and contributing to follicular dysfunction. Deletion of Igfbp4 in granulosa cells enhances ovulatory output, improves hormone profiles, and reproductive performance in aged female mice, suggesting ...

NONO, SFPQ, and PSPC1 promote telomerase recruitment to the telomere
Nature CommunicationsTelomerase is a ribonucleoprotein enzyme that maintains telomeric repeats on chromosome ends in continuously dividing cells. Telomere maintenance via telomerase is dependent on the correct assembly of the enzyme complex, complex stabilization by ...

BiomedicinesProper telomere maintenance is crucial for ensuring healthy cellular function. Telomeres have a tendency to reduce in length with cellular aging. Moreover several factors may promote telomere attrition.

Telomere length and incident atrial fibrillation - data of the PREVEND cohort.
PLoS ONE, 2017 BackgroundThe incidence of atrial fibrillation (AF) increases with age. Telomere length is considered a marker of biological ageing. We investigated the association between leukocyte telomere length and incident AF in the Dutch Prevention of Renal and ...

Early-Life Telomere Dynamics Differ between the Sexes and Predict Growth in the Barn Swallow (Hirundo rustica). [PDF]
PLoS ONE, 2015 Telomeres are conserved DNA-protein structures at the termini of eukaryotic chromosomes which contribute to maintenance of genome integrity, and their shortening leads to cell senescence, with negative consequences for organismal functions.

The EMBO Reports, 2002 Telomeres are protein-DNA complexes that cap chromosome ends and protect them from being recognized and processed as DNA breaks. Loss of capping function results in genetic instability and loss of cellular viability. The emerging view is that maintenance of an appropriate telomere structure is essential for function. Structural information on telomeric

Advanced Science, EarlyView.This study uncovers an unusual RNAi pathway in the rhizarian pathogen Plasmodiophora brassicae. In the absence of Dicer, a Drosha‐like RNase III protein supports the biogenesis of predominant 21‐nt small RNAs, and two Argonaute proteins mediate small RNA‐guided silencing.

Characterization and consequences of Telomere replication gone awry [PDF]
, 2008 Telomeres, the ends of linear eukaryotic chromosomes, pose several unique challenges to genome stability. My thesis work is concerned with the difficulties the replication machinery encounters when attempting to replicate telomeres, and with possible ...

hnRNPA2 mediated acetylation reduces telomere length in response to mitochondrial dysfunction.
PLoS ONE, 2018 Telomeres protect against chromosomal damage. Accelerated telomere loss has been associated with premature aging syndromes such as Werner's syndrome and Dyskeratosis Congenita, while, progressive telomere loss activates a DNA damage response leading to ...

Advanced Science, EarlyView.Frequent sweetened beverage consumption is associated with accelerated biological aging in a large Chinese population. Five gut microbial genera are consistently enriched in both frequent sweetened beverage consumers and individuals with accelerated aging and show significant mediating effects, suggesting a potential microbiota‐related pathway linking ...
