Signalling, cell cycle and pluripotency in embryonic stem cells [PDF]
, 2002 Pluripotent mouse embryonic stem (ES) cells can be expanded in large numbers in vitro owing to a process of symmetrical self-renewal. Self-renewal entails proliferation with a concomitant suppression of differentiation.

Keap1 modulates the redox cycle and hepatocyte cell cycle in regenerating liver [PDF]
, 2014 Keap1 negatively controls the activity of transcription factor Nrf2. This Keap1/Nrf2 pathway plays a critical role in combating oxidative stress. We aimed at determining whether and how Keap1 modulates the cell cycle of replicating hepatocytes during ...

A neural progenitor mitotic wave is required for asynchronous axon outgrowth and morphology
eLife, 2022 Spatiotemporal mechanisms generating neural diversity are fundamental for understanding neural processes. Here, we investigated how neural diversity arises from neurons coming from identical progenitors.

Nature 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 ...

IRBIT Directs Differentiation of Intestinal Stem Cell Progeny to Maintain Tissue Homeostasis
iScience, 2020 Summary: The maintenance of the intestinal epithelium is ensured by the controlled proliferation of intestinal stem cells (ISCs) and differentiation of their progeny into various cell types, including enterocytes (ECs) that both mediate nutrient ...

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

Antagonistic effects of mitochondrial matrix and intermembrane space proteases on yeast aging
BMC Biology, 2022 Background In many organisms, aging is characterized by a loss of mitochondrial homeostasis. Multiple factors such as respiratory metabolism, mitochondrial fusion/fission, or mitophagy have been linked to cell longevity, but the exact impact of each one ...

Fly, 2008 Drosophila researchers met in sunny San Diego for the 49(th) Annual Meeting of The Genetics Society of America. It was cold outside and even colder inside. Like last year, 'Mitosis, Meiosis and Cell Division' was no longer a session. Instead, we searched out and covered talks and posters in 'Cell Division and Growth Control', 'Gametogenesis ...

Antioxidants, 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.
