Parental status and markers of brain and cellular age: A 3D convolutional network and classification study

Recent research shows prominent effects of pregnancy and the parenthood transition on structural brain characteristics in humans. Here, we present a comprehensive study of how parental status and number of children born/fathered links to markers of brain a ...

A CTCF-dependent mechanism underlies the Hox timer relation to a segmented body plan

Denis Duboule, Hocine Rekaik

During gastrulation, Hox genes are activated in a timesequence that follows the order of the genes along their clusters. This property, which is observed in all animals that develop following a progressive rostral-to-caudal morphogenesis, is associated wit ...

Epigenetic ageing accelerates before antiretroviral therapy and decelerates after viral suppression in people with HIV in Switzerland: a longitudinal study over 17 years

Jacques Fellay, Christian Axel Wandall Thorball

Background Accelerated epigenetic ageing can occur in untreated HIV infection and is partially reversible with effective antiretroviral therapy (ART). We aimed to make a long-term comparison of epigenetic ageing dynamics in people with HIV during untreated ...

Aging Fly Cell Atlas identifies exhaustive aging features at cellular resolution

Maria Brbic, Sandy Lee

Aging is characterized by a decline in tissue function, but the underlying changes at cellular resolution across the organism remain unclear. Here, we present the Aging Fly Cell Atlas, a single-nucleus transcriptomic map of the whole aging Drosophila. We c ...

Epigenome-wide DNA methylation in externalizing behaviours: A review and combined analysis

Maria del Carmen Sandi Perez, Mandy Meijer

DNA methylation (DNAm) is one of the most frequently studied epigenetic mechanisms facilitating the interplay of genomic and environmental factors, which can contribute to externalizing behaviours and related psychiatric disorders. Previous epigenome-wide ...

Clinical efficacy of ONC201 in H3K27M-mutant diffuse midline gliomas is driven by disruption of integrated metabolic and epigenetic pathways

Sebastian Martin Waszak, Li Jiang

H3K27M-mutant diffuse midline glioma (DMG) patients have no proven effective therapies. ONC201 has recently demonstrated efficacy in these patients, but the mechanism behind this remains unknown. We assessed clinical outcomes, tumor sequencing, and tissue/ ...

Predictive health assessment for lithium-ion batteries with probabilistic degradation prediction and accelerating aging detection

Florent Evariste Forest, Yunhong Che

Predictive health assessment is of vital importance for smarter battery management to ensure optimal and safe operations and thus make the most use of battery life. This paper proposes a general framework for battery aging prognostics in order to provide t ...

The circadian clock time tunes axonal regeneration

Thomas Haynes Hutson

Nerve injuries cause permanent neurological disability due to limited axonal regeneration. Injury-dependent and-independent mechanisms have provided important insight into neuronal regeneration, however, common denominators underpinning regeneration remain ...

Epigenetic plasticity as a signature for memory allocation

Giulia Santoni

Long-lasting memories are stored in a small set of neurons scattered throughout the brain, so-called engram cells. To define a stable engram each region of the brain involved in memory storage recruits between 5 and 20 percent of excitatory neurons. In par ...

Current challenges in understanding the role of enhancers in disease

Bart Deplancke

Enhancers play a central role in the spatiotemporal control of gene expression and tend to work in a cell-type-specific manner. In addition, they are suggested to be major contributors to phenotypic variation, evolution and disease. There is growing eviden ...

The Gene-Regulatory Footprint of Aging Highlights Conserved Central Regulators

Johan Auwerx, Richardus Houtkooper, Maroun Bou Sleiman, Xu Wang, Pooja Jha

Many genes and pathways have been linked to aging, yet our understanding of underlying molecular mechanisms is still lacking. Here, we measure changes in the transcriptome, histone modifications, and DNA methylome in three metabolic tissues of adult and ag ...

Comprehensive analysis of PM20D1 QTL in Alzheimer's disease

Johannes Gräff, Liliane Glauser, Jose Vicente Sanchez Mut

Background Alzheimer's disease (AD) is a complex disorder caused by a combination of genetic and non-genetic risk factors. In addition, an increasing evidence suggests that epigenetic mechanisms also accompany AD. Genetic and epigenetic factors are not ind ...

Disturbed mitochondrial dynamics in CD8(+)TILs reinforce T cell exhaustion

Li Tang, Nicola Vannini, George Coukos, Marcela Rincón-Restrepo, Min Gao, Fabien Franco

Ho and colleagues report that mitochondrial dysfunction and impaired mitophagy triggered by the tumor microenvironment lead to subsequent epigenetic changes and cause permanent T cell exhaustion and dysfunction. The metabolic challenges present in tumors a ...

STAT3 promotes melanoma metastasis by CEBP-induced repression of the MITF pathway

Friedrich Beermann

Metastatic melanoma is hallmarked by its ability of phenotype switching to more slowly proliferating, but highly invasive cells. Here, we tested the impact of signal transducer and activator of transcription 3 (STAT3) on melanoma progression in association ...

A Tale of Two Tumors: Unraveling the Complexities of Epigenetic Dysregulation in Cancer

Maria Christine Donaldson

Epigenetics plays an important role in cancer development and progression. Cancer cells hijack the epigenome by modifying the histone protein units responsible for packaging DNA, or by modifying the DNA itself, resulting in changes to chromatin topology an ...

Basic creep of cement paste at early age - the role of cement hydration

Karen Scrivener, Pietro Lura

In this work, the uniaxial creep in compression during the first days of hydration is studied experimentally on cement pastes with w/c of 0.50. to order to assess the effect of the evolving microstructure on creep, the so-called equivalent systems are empl ...

Methods of diagnosis alzheimer's disease

Johannes Gräff, Jose Vicente Sanchez Mut

A method for the diagnosis or prognosis of Alzheimer's disease (AD), includes the steps of placing a sample isolated from a person suspected of having AD onto a substrate labeling the sample to identify at least one epigenetic marker and/or genetic variati ...

Machine Learning Identifies Stemness Features Associated with Oncogenic Dedifferentiation

Jia Liu, Jian Wang, Wei Zhang, Jun Li, Min Wang, Wei Li, Hui Shen, Li Ding, Yi Han, Phuong Nguyen, Han Liang, Luca Mattei

Cancer progression involves the gradual loss of a differentiated phenotype and acquisition of progenitor and stem-cell-like features. Here, we provide novel stemness indices for assessing the degree of oncogenic dedifferentiation. We used an innovative one ...

Telomeric states in cancer development

Jana Majerská

Telomere dysfunction can unleash genome instability or permanently arrest cell proliferation, and thereby contribute to the processes of cancer and aging. Proper telomere function relies on many proteins that form part of its structure. Some telomeric prot ...

Epigenetic approach for angiostatic therapy: promising combinations for cancer treatment

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Ume-Gulsoom Abdul, Marije Trudi Te Winkel

Cancer cells are often dependent on epigenetic pathways for their survival. Consequently, drugs that target the epigenome, rather than the underlying DNA sequence, are currently attracting considerable attention. In recent years, the first epigenetic drugs ...
