A neural progenitor mitotic wave is required for asynchronous axon outgrowth and morphology

open access: yeseLife, 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.

ATR Kinase Is a Crucial Player Mediating the DNA Damage Response in Trypanosoma brucei

open access: yesFrontiers in Cell and Developmental Biology, 2020
DNA double-strand breaks (DSBs) are among the most deleterious lesions that threaten genome integrity. To address DSBs, eukaryotic cells of model organisms have evolved a complex network of cellular pathways that are able to detect DNA damage, activate a

Antagonistic effects of mitochondrial matrix and intermembrane space proteases on yeast aging

open access: yesBMC 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 ...

Targeting of Fzr/Cdh1 for timely activation of the APC/C at the centrosome during mitotic exit

open access: yesNature Communications, 2016
The activity of the anaphase-promoting complex/cyclosome (APC/C) needs to be regulated in time and space to perform different functions. Here the authors show that Spd2 localizes the APC/C activator Fzr at the centrosomes to promote optimal APC/C ...

Cdc14 phosphatase counteracts Cdk-dependent Dna2 phosphorylation to inhibit resection during recombinational DNA repair

open access: yesNature Communications, 2023
Cyclin-dependent kinase (Cdk) stimulates resection of DNA double-strand breaks ends to generate single-stranded DNA (ssDNA) needed for recombinational DNA repair.

Conditional control of fluorescent protein degradation by an auxin-dependent nanobody

open access: yesNature Communications, 2018
Current approaches to conditionally deplete target proteins require site-specific genetic engineering or have poor temporal control. Here the authors overcome these limitations by combining the AID system with nanobodies to reversibly degrade GFP-tagged ...

Cell Cycle Regulation [PDF]

open access: yesFly, 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 ...

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 ...

IRBIT Directs Differentiation of Intestinal Stem Cell Progeny to Maintain Tissue Homeostasis

open access: yesiScience, 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

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 ...
