The contribution of age structure to cell population responses to targeted therapeutics [PDF]

open access: yes, 2012
Cells grown in culture act as a model system for analyzing the effects of anticancer compounds, which may affect cell behavior in a cell cycle position-dependent manner.

Phosphotransferase-dependent accumulation of (p)ppGpp in response to glutamine deprivation in Caulobacter crescentus

open access: yesNature Communications, 2016
The small molecule (p)ppGpp is commonly produced by bacteria as a signal of nutrient starvation. Here, Ronneau et al. show that (p)ppGpp accumulation in the model bacterium Caulobacter crescentusis modulated by a nitrogen-related phosphotransferase ...

A coupled drug kinetics-cell cycle model to analyse the response of human cells to intervention by topotecan [PDF]

open access: yes, 2008
A model describing the response of the growth of single human cells in the absence and presence of the anti-cancer agent topotecan (TPT) is presented. The model includes a novel coupling of both the kinetics of TPT and cell cycle responses to the agent ...

Metabolic control of cell division in α-proteobacteria by a NAD-dependent glutamate dehydrogenase

open access: yesCommunicative & Integrative Biology, 2016
Prior to initiate energy-consuming processes, such as DNA replication or cell division, cells need to evaluate their metabolic status. We have recently identified and characterized a new connection between metabolism and cell division in the α ...

Comparing Mitochondrial Activity, Oxidative Stress Tolerance, and Longevity of Thirteen Ascomycota Yeast Species

open access: yesAntioxidants, 2023
Aging is characterized by a number of hallmarks including loss of mitochondrial homeostasis and decay in stress tolerance, among others. Unicellular eukaryotes have been widely used to study chronological aging.

The zinc finger transcription factor PW1/PEG3 restrains murine beta cell cycling [PDF]

open access: yes, 2016
Aims/hypothesis: Pw1 or paternally-expressed gene 3 (Peg3) encodes a zinc finger transcription factor that is widely expressed during mouse embryonic development and later restricted to multiple somatic stem cell lineages in the adult.

Regrowth resistance: low-level platinum resistance mediated by rapid recovery from platinum-induced cell-cycle arrest [PDF]

open access: yes, 2009
The H69CIS200 and H69OX400 cell lines are novel models of low-level platinum drug resistance developed from H69 human small cell lung cancer cells with eight 4-day treatments of 200 ng/ml cisplatin or 400 ng/ml oxaliplatin respectively. A recovery period

Identification of ubiquitin-proteasome system components affecting the degradation of the transcription factor Pap1

open access: yesRedox Biology, 2020
Signaling cascades respond to specific inputs, but also require active interventions to be maintained in their basal/inactive levels in the absence of the activating signal(s).

DYRK1A and the Cell Cycle [PDF]

open access: yes, 2020
The ability to halt the cell cycle is critical for cells to maintain tissue and organ size, to suppress tumors and abnormal growth, and exists as a helpful mechanism to pause the cell cycle for DNA repair.
