Distinct epigenetic aging in sporadic and hereditary neuroendocrine neoplasms

open access: yesClinical Epigenetics
Background Epigenetic clocks assess DNA aging based on DNA methylation. We aimed to study the utility of methylation clocks in understanding the distinct characteristics of sporadic and hereditary neuroendocrine neoplasms (NEN).

Epigenetic aging signatures in mice livers are slowed by dwarfism, calorie restriction and rapamycin treatment

open access: yesGenome Biology, 2017
Background Global but predictable changes impact the DNA methylome as we age, acting as a type of molecular clock. This clock can be hastened by conditions that decrease lifespan, raising the question of whether it can also be slowed, for example, by ...

Nerve growth factor, brain-derived neurotrophic factor, and the chronobiology of mood: a new insight into the "neurotrophic hypothesis" [PDF]

open access: yes, 2015
The light information pathways and their relationship with the body rhythms have generated a new insight into the neurobiology and the neurobehavioral sciences, as well as into the clinical approaches to human diseases associated with disruption of ...

Designing Epigenetic Clocks for Wildlife Research

open access: yesMolecular Ecology Resources
ABSTRACTThe applications of epigenetic clocks – statistical models that predict an individual's age based on DNA methylation patterns – are expanding in wildlife conservation and management. This growing interest highlights the need for field‐specific design best practices.

Dynamics of 5-methylcytosine and 5-hydroxymethylcytosine during pronuclear development in equine zygotes produced by ICSI [PDF]

open access: yes, 2017
Background: Global epigenetic reprogramming is considered to be essential during embryo development to establish totipotency. In the classic model first described in the mouse, the genome-wide DNA demethylation is asymmetric between the paternal and the ...

The Unicellular State as a Point Source in a Quantum Biological System. [PDF]

open access: yes, 2016
A point source is the central and most important point or place for any group of cohering phenomena. Evolutionary development presumes that biological processes are sequentially linked, but neither directed from, nor centralized within, any specific ...

Waves and patterning in developmental biology: vertebrate segmentation and feather bud formation as case studies [PDF]

open access: yes, 2009
In this article we will discuss the integration of developmental patterning mechanisms with waves of competency that control the ability of a homogeneous field of cells to react to pattern forming cues and generate spatially heterogeneous patterns.

Immunotronics - novel finite-state-machine architectures with built-in self-test using self-nonself differentiation [PDF]

open access: yes, 2002
A novel approach to hardware fault tolerance is demonstrated that takes inspiration from the human immune system as a method of fault detection. The human immune system is a remarkable system of interacting cells and organs that protect the body from ...

Mutation and epigenetic molecular clocks in cancer [PDF]

open access: yesCarcinogenesis, 2010
A quandary of evolution is how to measure change over time. A natural inclination is to use morphologic criteria-the greater the differences between two phenotypes, the greater amount of time needed to evolve these differences. However, appearances may be deceiving, and another approach to infer time is with molecular clocks.

An expedited screening platform for the discovery of anti-ageing compounds in vitro and in vivo

open access: yesGenome Medicine
Background Restraining or slowing ageing hallmarks at the cellular level have been proposed as a route to increased organismal lifespan and healthspan. Consequently, there is great interest in anti-ageing drug discovery.
