Coupling of the radiosensitivity of melanocyte stem cells to their dormancy during the hair cycle [PDF]
Pigment Cell & Melanoma Research, 2014 SummaryCurrent studies have revealed that stem cells are more radiosensitive than mature cells. As somatic stem cells are mostly kept in a quiescent state, this conflicts with Bergonié and Tribondeau's law that actively mitotic cells are the most radiosensitive. In this study, we focused on hair graying to understand the stress‐resistance of melanocyte

The impact of dormancy on evolutionary branching [PDF]
arXiv, 2022 In this paper, we investigate the consequences of dormancy in the `rare mutation' and `large population' regime of stochastic adaptive dynamics. Starting from an individual-based micro-model, we first derive the polymorphic evolution sequence of the population, based on previous work by Baar and Bovier (2018). After passing to a second `small mutations'

Tracking of Normal and Malignant Progenitor Cell Cycle Transit in a Defined Niche. [PDF]
, 2016 While implicated in therapeutic resistance, malignant progenitor cell cycle kinetics have been difficult to quantify in real-time. We developed an efficient lentiviral bicistronic fluorescent, ubiquitination-based cell cycle indicator reporter (Fucci2BL)

A Stochastic Adaptive Dynamics Model for Bacterial Populations with Mutation, Dormancy and Transfer [PDF]
arXiv, 2021 This paper introduces a stochastic adaptive dynamics model for the interplay of several crucial traits and mechanisms in bacterial evolution, namely dormancy, horizontal gene transfer (HGT), mutation and competition. In particular, it combines the recent model of Champagnat, M\'el\'eard and Tran (2021) involving HGT with the model for competition ...

TGF-β2 dictates disseminated tumour cell fate in target organs through TGF-β-RIII and p38α/β signalling [PDF]
, 2013 In patients, non-proliferative disseminated tumour cells (DTCs) can persist in the bone marrow (BM) while other organs (such as lung) present growing metastasis.

Dormancy cycling is accompanied by changes in ABA sensitivity in Polygonum aviculare seeds
Journal of Experimental Botany, 2020 Abstract Polygonum aviculare seeds show high levels of primary dormancy (PD). Low winter temperatures alleviate dormancy and high spring temperatures induce seeds into secondary dormancy (SD), naturally establishing stable seedbanks cycling through years.

Arabidopsis thaliana DOF6 negatively affects germination in non-after ripened seeds and interacts with TCP14 [PDF]
, 2011 Seed dormancy prevents seeds from germinating under environmental conditions unfavourable for plant growth and development and constitutes an evolutionary advantage.

Selection Mapping Identifies Loci Underpinning Autumn Dormancy in Alfalfa (Medicago sativa). [PDF]
, 2018 Autumn dormancy in alfalfa (Medicago sativa) is associated with agronomically important traits including regrowth rate, maturity, and winter survival. Historical recurrent selection experiments have been able to manipulate the dormancy response.
