Emerging Roles for Transcription Factors During Mitosis [PDF]
CellsThe genome is dynamically reorganized, partitioned, and divided during mitosis. Despite their role in organizing interphase chromatin, transcription factors were largely believed to be mitotic spectators evicted from chromatin during mitosis, only able ...

Mitosis recursion for coefficients of Schubert polynomials [PDF]
arXiv, 2002 Mitosis is a rule introduced by [Knutson-Miller, 2002] for manipulating subsets of the n by n grid. It provides an algorithm that lists the reduced pipe dreams (also known as rc-graphs) [Fomin-Kirillov, Bergeron-Billey] for a permutation w in S_n by downward induction on weak Bruhat order, thereby generating the coefficients of Schubert polynomials ...

Preparation for mitosis requires gradual CDK1 activation [PDF]
iScienceSummary: G2 phase is considered as a time in which cells prepare for the large structural changes in the following mitosis. Starting at completion of DNA replication, CDK1 and PLK1 kinase activities gradually increase throughout G2 phase until reaching ...

Non-autonomous insulin signaling delays mitotic progression in C. elegans germline stem and progenitor cells. [PDF]
PLoS GeneticsStem and progenitor cell mitosis is essential for tissue development and homeostasis. How these cells ensure proper chromosome segregation, and thereby maintain mitotic fidelity, in the complex physiological environment of a living animal is poorly ...

Ki-67 and CDK1 control the dynamic association of nuclear lipids with mitotic chromosomes [PDF]
Journal of Lipid ResearchNuclear lipids play roles in regulatory processes, such as signaling, transcriptional regulation, and DNA repair. In this report, we demonstrate that nuclear lipids may contribute to Ki-67-regulated chromosome integrity during mitosis.

Human Cdc14B promotes progression through mitosis by dephosphorylating Cdc25 and regulating Cdk1/cyclin B activity. [PDF]
PLoS ONE, 2011 Entry into and progression through mitosis depends on phosphorylation and dephosphorylation of key substrates. In yeast, the nucleolar phosphatase Cdc14 is pivotal for exit from mitosis counteracting Cdk1-dependent phosphorylations.

Contextual Prior Constrained Deep Networks for Mitosis Detection With Point Annotations
IEEE Access, 2021 We study the problem of training an accurate deep learning mitosis detection model with only point annotations. To address this challenging label-efficient deep learning problem, we propose a novel contextual prior constraint mechanism and spatial area ...

Turning end-joining upside down in mitosis
Molecular & Cellular Oncology, 2021 How cells deal with DNA breaks during mitosis is not well understood. While canonical non-homologous end-joining predominates in interphase, it is inhibited in mitosis to avoid telomere fusions.

Anti-tumor pharmacology of natural products targeting mitosis
Cancer Biology & Medicine, 2022 Cancer has been an insurmountable problem in the history of medical science. The uncontrollable proliferation of cancer cells is one of cancer’s main characteristics, which is closely associated with abnormal mitosis.

SmallMitosis: Small Size Mitotic Cells Detection in Breast Histopathology Images
IEEE Access, 2021 Mitotic figure count acts as a proliferative marker to measure aggressiveness of the breast cancer tumor. In this article, we have proposed a novel framework named SmallMitosis to detect mitotic cells particularly very small size mitosis from hematoxylin
