CCDC41 Drives Oocyte Meiotic Progression by Promoting Rab11a/Rab7‐Positive Vesicle Fusion with Target Membranes

open access: yesAdvanced Science, EarlyView.
CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

Deficiency of mastl, a mitotic regulator, results in cell detachment from developing tissues of zebrafish embryos

open access: yesFrontiers in Cell and Developmental Biology
To form tissues with unique functions and structures, it is important that the cells that comprise them maintain physical contact. On the other hand, with each mitosis, drastic changes in cell shapes, cell adhesion, and cytoskeletal architecture may ...

Assessment of algorithms for mitosis detection in breast cancer histopathology images [PDF]

open access: yes, 2014
The proliferative activity of breast tumors, which is routinely estimated by counting of mitotic figures in hematoxylin and eosin stained histology sections, is considered to be one of the most important prognostic markers.

Interactions of Antibody Drug Conjugate Anti‐Tubulin and Topoisomerase I Inhibitor Payloads with Radiotherapy to Potentiate Immunotherapy

open access: yesAdvanced Science, EarlyView.
Antibody drug conjugates deliver their cytotoxic anti‐tubulin or topoisomerase I inhibitor payloads to tumors through cancer cell receptor targeting. The released drug payloads induce cellular changes that interact with radiotherapy resulting in radiosensitization that improves cancer cell kill and stimulates anti‐tumor immune responses.

Unveiling an Arpp-19 phosphorylation switch that grants chromosome stability

open access: yesCommunications Biology
During cell division, the onset of mitosis is granted by activation of cyclin B-dependent kinase 1 (Cdk1), master mitotic kinase, coordinated with inactivation of Cdk1-counteracting phosphatases.

Ki-67 and CDK1 control the dynamic association of nuclear lipids with mitotic chromosomes

open access: yesJournal of Lipid Research
Nuclear 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.

A simple biophysical model emulates budding yeast chromosome condensation

open access: yeseLife, 2015
Mitotic chromosomes were one of the first cell biological structures to be described, yet their molecular architecture remains poorly understood. We have devised a simple biophysical model of a 300 kb-long nucleosome chain, the size of a budding yeast ...

Epstein‐Barr Virus Expressed Long Non‐Coding RNA (lncBARTs) Regulate EBV Latent Genome Replication

open access: yesAdvanced Science, EarlyView.
EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.

Developing cell biology

open access: yeseLife, 2013
Experiments in Xenopus embryo extracts reveal that changes in cellular biochemistry cause mitotic spindles to decrease in size over the course of early development.
