RepeatOBserver: Tandem Repeat Visualisation and Putative Centromere Detection

Molecular Ecology Resources, EarlyView.
ABSTRACT Tandem repeats play an important role in centromere structure, subtelomeric regions, DNA methylation, recombination and the regulation of gene activity. Analysis of their distribution in genomes offers a potential means for predicting putative centromere locations, which continues to be a challenge for genome annotation.

Age and Sex Effects on Blood Retrotransposable Element Expression Levels: Findings From the Population‐Based Rhineland Study

Aging Cell, EarlyView.
Retrotransposable element (RTE) expression increases with chronological and biological age and is negatively associated with heterochromatin regulators. Moreover, RTE expression shows sex‐specific differences, with higher levels in men and enrichment for immune‐related pathways.

hTERT Increases TRF2 to Induce Telomere Compaction and Extend Cell Replicative Lifespan

Aging Cell, EarlyView.
In contrast to the dogma that a subset of short telomeres initiates senescence, hTERT variants unable to maintain telomere length block senescence by stabilizing TRF2 via inhibiting upstream E3 ubiquitin ligases. This noncanonical hTERT function also compacts telomeres and blocks senescence‐associated DNA damage signaling. Cancer cells expressing hTERT

Cross‐Analysis of Single‐Cell Transcriptomic Datasets Reveals Conserved Neurogenic Gene Signatures and New Insights Into Neural Stem Cell Aging

Aging Cell, EarlyView.
Here, we reanalyze single‐cell RNA sequencing datasets demonstrating hippocampal adult neural stem cell (NSC) heterogeneity to resolve classification inconsistencies and identify conserved gene markers. Our findings enhance understanding of NSC dynamics, aging, and senescence, providing a framework for standardized classification and improved insights ...

Phenotypic continuum and poor intracytoplasmic sperm injection intracytoplasmic sperm injection prognosis in patients harboring HENMT1 variants

Andrology, EarlyView.
Abstract Background Small RNAs interacting with PIWI (piRNAs) play a crucial role in regulating transposable elements and translation during spermatogenesis and are essential in male germ cell development. Disruptions in the piRNA pathway typically lead to severe spermatogenic defects and thus male infertility. The HENMT1 gene is a key player in piRNAs

EP300‐interacting inhibitor of differentiation 3 is required for spermatogenesis in mice

Andrology, EarlyView.
Abstract Background Mammalian spermatogenesis is a highly complex process of cell proliferation, meiosis, and differentiation. A series of genes are expressed in an orderly and precise manner to ensure spermatogenesis, with chromatin undergoing intricate changes throughout.
