Ubiquitin signaling in cell cycle control and tumorigenesis
Cell Death and Differentiation, 2020 Cell cycle progression is a tightly regulated process by which DNA replicates and cell reproduces. The major driving force underlying cell cycle progression is the sequential activation of cyclin-dependent kinases (CDKs), which is achieved in part by the

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

Acanthamoeba induces cell-cycle arrest in host cells [PDF]
, 2004 Acanthamoeba can cause fatal granulomatous amoebic encephalitis (GAE) and eye keratitis. However, the pathogenesis and pathophysiology of these emerging diseases remain unclear.

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 ...

The cell cycle program of polypeptide labeling in Chlamydomonas reinhardtii [PDF]
, 1977 The cell cycle program of polypeptide labeling in syndhronous cultures of wild-type Chlamydomonas reinhardtii was analyzed by pulse-labeling cells with 35SO4 = or [3H]arginine at different cell cycle stages.

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 ...

Characterizing stochastic cell cycle dynamics in exponential growth [PDF]
Phys. Rev. E 105, 014420 (2022), 2021 Two powerful and complementary experimental approaches are commonly used to study the cell cycle and cell biology: One class of experiments characterizes the statistics (or demographics) of an unsynchronized exponentially-growing population, while the other captures cell cycle dynamics, either by time-lapse imaging of full cell cycles or in bulk ...

Journal of Immunology, 1984 The monoclonal antibody Ki-67 detects a nuclear antigen that is present only in proliferating cells. The aim of the present investigation was to clarify whether the Ki-67 nuclear antigen is restricted in its expression to certain phases of the cell cycle.

Neoplasia, 2000 In multicellular organisms, cell proliferation and death must be regulated to maintain tissue homeostasis. Many observations suggest that this regulation may be achieved, in part, by coupling the process of cell cycle progression and programmed cell death by using and controlling a shared set of factors.
