Regulation of anaphase in mammalian meiosis

open access: yes, 2012
Missegregation of chromosomes during meiosis leads to formation of aneuploid eggs. Estimates suggest that in humans, about 10-30% of fertilised eggs and one-third of all miscarriages are aneuploid. Accurate chromosome segregation depends on the coordination between stepwise cohesion resolution and attachments of homologous chromosomes through ...

When the Clock Is Ticking: The Role of Mitotic Duration in Cell Fate Determination

open access: yesBioEssays, Volume 47, Issue 11, November 2025.
Recently, several studies identified mechanisms by which cells measure mitotic duration and how this influences cell fate, leading to normal cell cycle progression or G1 arrest. In light of drug‐resistant cancer cells that continue proliferating even after mitotic errors, understanding these mechanisms opens the door for new potential therapeutic ...

BUB1B Promotes Ovarian Cancer Cell Proliferation and Metastasis by Activating the Wnt/β‐Catenin Pathway

open access: yesCancer Medicine, Volume 14, Issue 21, November 2025.
ABSTRACT Background BUB1 mitotic checkpoint serine/threonine kinase B (BUB1B) has been found to participate in cancer progression. Nevertheless, the function and mechanism of BUB1B in ovarian cancer (OC) remain unknown. Method Based on datasets GSE14407, GSE18520, and the TCGA combined GTEx database, the differently expressed genes (DEGs) between OC ...

THE ANAPHASE MOVEMENT OF CHROMOSOMES IN THE SPERMATOCYTES OF THE GRASSHOPPER

open access: yesThe Biological Bulletin, 1949
The movement of chromosomes and the changes in spindle size have been recorded in living spermatocytes of the grasshopper during the meiotic divisions. Anaphase movement consists of two separate processes which are related to the action of distinct cellular organelles: (1) The shortening of chromosomal fibers moves the chromosomes to the poles. (2) The
