Detection of Ultrafine Anaphase Bridges [PDF]
Ultrafine anaphase bridges (UFBs) are thin DNA threads linking the separating sister chromatids in the anaphase of mitosis. UFBs are thought to form when topological DNA entanglements between two chromatids are not resolved prior to anaphase onset.

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.

Mitotic Exit Function of Polo-like Kinase Cdc5 Is Dependent on Sequential Activation by Cdk1
To complete mitosis, Saccharomyces cerevisiae needs to activate the mitotic phosphatase Cdc14. Two pathways contribute to Cdc14 regulation: FEAR (Cdc14 early anaphase release) and MEN (mitotic exit network).

Chromosome movement in lysed mitotic cells is inhibited by vanadate. [PDF]
Mitotic PtK1 cells, lysed at anaphase into a carbowax 20 M Brij 58 solution, continue to move chromosomes toward the spindle poles and to move the spindle poles apart at 50% in vivo rates for 10 min.

Mad2, Bub3, and Mps1 regulate chromosome segregation and mitotic synchrony in Giardia intestinalis, a binucleate protist lacking an anaphase-promoting complex. [PDF]
The binucleate pathogen Giardia intestinalis is a highly divergent eukaryote with a semiopen mitosis, lacking an anaphase-promoting complex/cyclosome (APC/C) and many of the mitotic checkpoint complex (MCC) proteins.

DNA damage induced during mitosis undergoes DNA repair synthesis. [PDF]
Understanding the mitotic DNA damage response (DDR) is critical to our comprehension of cancer, premature aging and developmental disorders which are marked by DNA repair deficiencies.

CDH1 Orchestrates Anabolic Events to Promote Cell Cycle Initiation
Cell proliferation requires the integration of cell cycle and anabolic signals. G1‐phase regulator CDH1 coordinates anabolism through the CDH1‐VHL‐AARS2/HIF1α axis, while CDH1‐accumulated R5P is sensed by TKTL1 to facilitate CDH1 degradation and cell cycle initiation, constituting a CDH1‐centered regulatory circuit.

Condensin II resolves chromosomal associations to enable anaphase I segregation in Drosophila male meiosis. [PDF]
Several meiotic processes ensure faithful chromosome segregation to create haploid gametes. Errors to any one of these processes can lead to zygotic aneuploidy with the potential for developmental abnormalities.

The meiosis-specific Cdc20 family-member Ama1 promotes binding of the Ssp2 activator to the Smk1 MAP kinase. [PDF]
Smk1 is a meiosis-specific MAP kinase (MAPK) in budding yeast that is required for spore formation. It is localized to prospore membranes (PSMs), the structures that engulf haploid cells during meiosis II (MII).

This study uncovers a previously unknown crosstalk between two major ubiquitin ligases, CRL5 and APC/C. The authors identify APC11 as a binding partner of CUL5, showing that their interaction regulates neddylation, substrate stability, and mitotic progression.
