Plasma membrane/cell wall perturbation activates a novel cell cycle checkpoint during G1 in Saccharomyces cerevisiae

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance Cells need to rapidly control their cell cycle profile, gene expression, or protein stability in response to the activation of stress-response pathways.

Gene Copy Number and Cell Cycle Arrest [PDF]

open access: yes, 2005
The cell cycle is an orderly sequence of events which ultimately lead to the division of a single cell into two daughter cells. In the case of DNA damage by radiation or chemicals, the damage checkpoints in the $G_{1}$ and $G_{2}$ phases of the cell cycle are activated. This results in an arrest of the cell cycle so that the DNA damage can be repaired.

Critical slowing down and attractive manifold: a mechanism for dynamic robustness in yeast cell-cycle process [PDF]

open access: yesPhys. Rev. E 101, 042405 (2020), 2018
The biological processes that execute complex multiple functions, such as cell cycle, must ensure the order of sequential events and keep the dynamic robustness against various fluctuations. Here, we examine the dynamic mechanism and the fundamental structure to achieve these properties in the cell-cycle process of budding yeast Saccharomyces ...

Primary extranodal diffuse large B‐cell lymphoma: Molecular features, treatment, and prognosis

open access: yesAging and Cancer, Volume 3, Issue 3-4, Page 133-146, September-December 2022., 2022
One‐third of DLBCL arises from extranodal organs and is challenging to manage. Molecular features are critical to elucidate the differences in clinical features, predict the disease prognosis, and improve effective targeted therapeutic strategies. Abstract Diffuse large B‐cell lymphoma (DLBCL) is the most common subtype of non‐Hodgkin's lymphoma and ...

Mammalian cells lack checkpoints for tetraploidy, aberrant centrosome number, and cytokinesis failure

open access: yesBMC Cell Biology, 2005
Background Mammalian cells have been reported to have a p53-dependent tetraploidy checkpoint that blocks cell cycle progression in G1 in response to failure of cell division.

Cryptochrome, Circadian Cycle, Cell Cycle Checkpoints, and Cancer [PDF]

open access: yesCancer Research, 2005
Abstract It has been reported that disruption of the circadian clock may lead to increased risk of breast cancer in humans and to a high rate or ionizing radiation–induced tumors and mortality in mice. Cryptochrome 1 and cryptochrome 2 proteins are core components of the mammalian circadian clock and mice mutated in both genes are ...

bir1 deletion causes malfunction of the spindle assembly checkpoint and apoptosis in yeast

open access: yesFrontiers in Oncology, 2012
Cell division in yeast is a highly regulated and well studied event. Various checkpoints are placed throughout the cell cycle to ensure faithful segregation of sister chromatids.

A checkpoint-oriented cell cycle simulation model [PDF]

open access: yesCell Cycle, 2019
Modeling and in silico simulations are of major conceptual and applicative interest in studying the cell cycle and proliferation in eukaryotic cells. In this paper, we present a cell cycle checkpoint-oriented simulator that uses agent-based simulation modeling to reproduce the dynamics of a cancer cell population in exponential growth.

Cyclin F suppresses B-Myb activity to promote cell cycle checkpoint control

open access: yesNature Communications, 2015
Cells respond to DNA damage by activating cell cycle checkpoints to delay proliferation and facilitate DNA repair. Here, to uncover new checkpoint regulators, we perform RNA interference screening targeting genes involved in ubiquitylation processes.

The role of CDC25C in cell cycle regulation and clinical cancer therapy: a systematic review

open access: yesCancer Cell International, 2020
One of the most prominent features of tumor cells is uncontrolled cell proliferation caused by an abnormal cell cycle, and the abnormal expression of cell cycle-related proteins gives tumor cells their invasive, metastatic, drug-resistance, and anti ...
