Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]

open access: yes, 2013
We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms

Hybrid Behavior-Genetic Models of the Confounding Gene-Environment Correlations in the Development of Life History Strategy: Two Convergent Approaches

open access: yesJournal of Methods and Measurement in the Social Sciences, 2021
Traditional theories of development and evolutionary developmental psychology propose that early environmental experiences shape an individual’s developmental trajectory.

Developmental Origins of Limb Developmental Instability in Human Fetuses: Many Abnormalities Make the Difference [PDF]

open access: yesSymmetry, 2017
Fluctuating asymmetry (FA) is the small random deviation from perfect symmetry in bilateral traits and is often used to assess developmental instability (DI) experienced by organisms. In this study, with a unique dataset of 1389 deceased human fetuses, we investigated the relationship between abnormal development and human limb FA in different ways ...

Labyrinthine Turing Pattern Formation in the Cerebral Cortex [PDF]

open access: yes, 2002
I propose that the labyrinthine patterns of the cortices of mammalian brains may be formed by a Turing instability of interacting axonal guidance species acting together with the mechanical strain imposed by the interconnecting axons.Comment: See home ...

Fluctuating asymmetry and developmental instability in Protoreaster nodosus (Chocolate Chip Sea Star) as a biomarker for environmental stress [PDF]

open access: yesComputational Ecology and Software, 2015
Fluctuating asymmetry (FA), pertains to small and random departures from perfect symmetry of an organism's bilateral traits and has been used as a measurement of developmental instability and as a potential indicator of stress in populations. It measures

Hypoxia in the Initiation and Progression of Neuroblastoma Tumours [PDF]

open access: yes, 2020
Neuroblastoma is the most frequent extracranial solid tumour in children, causing 10% of all paediatric oncology deaths. It arises in the embryonic neural crest due to an uncontrolled behaviour of sympathetic nervous system progenitors, giving rise to ...

Heterozygotic Brca1 mutation initiates mouse genome instability at embryonic stage

open access: yesOncogenesis, 2022
BRCA1 mutation is the genetic predisposition in causing genome instability towards cancer. BRCA1 mutation is predominantly germline inherited at the fertilization. However, when the inherited mutation initiates genome instability in the mutation carriers

Prenatal Developmental Trajectories of Fluctuating Asymmetry in Bat Humeri

open access: yesFrontiers in Cell and Developmental Biology, 2021
Fluctuating asymmetry (random fluctuations between the left and right sides of the body) has been interpreted as an index to quantify both the developmental instabilities and homeostatic capabilities of organisms, linking the phenotypic and genotypic ...

Dissecting the dynamics of signaling events in the BMP, WNT, and NODAL cascade during self-organized fate patterning in human gastruloids. [PDF]

open access: yes, 2019
During gastrulation, the pluripotent epiblast self-organizes into the 3 germ layers-endoderm, mesoderm and ectoderm, which eventually form the entire embryo.

Does the coefficient of variation reflect developmental instability in plants? [PDF]

open access: yesArchives of Biological Sciences, 2005
Developmental stability or homeostasis refers to the ability of an individual to produce a consistent phenotype in a given environment (Graham et al. 1993). Reduced developmental stability can result from a wide variety of environmentally (or genetically)
