Detection of Anaphase Bridge Formation by Immunofluorescence Microscopy in Mammalian Cells

Bio-Protocol, 2016
The aim of this protocol is to provide a comprehensive description of the materials, equipment and reproducible methods to detect and analyze anaphase bridges in immunofluorescence microscopy using DAPI to detect cells that failed to completely segregate

The synaptonemal complex stabilizes meiosis in allotetraploid Brassica napus and autotetraploid Arabidopsis thaliana

New Phytologist, Volume 246, Issue 2, Page 581-597, April 2025.
Summary Polyploidy plays a key role in genome evolution and crop improvement. The formation of bivalents rather than multivalents during meiosis of polyploids is essential to ensure meiotic stability and optimal fertility of the species. However, the mechanisms preventing multivalent recombination in polyploids remain obscure.

The checkpoint protein MAD2 and the mitotic regulator CDC20 form a ternary complex with the anaphase-promoting complex to control anaphase initiation.

Genes & Development, 1998
The spindle assembly checkpoint mechanism delays anaphase initiation until all chromosomes are aligned at the metaphase plate. Activation of the anaphase-promoting complex (APC) by binding of CDC20 and CDH1 is required for exit from mitosis, and APC has ...

BOrg: A Brain Organoid-Based Mitosis Dataset for Automatic Analysis of Brain Diseases [PDF]

arXiv
Recent advances have enabled the study of human brain development using brain organoids derived from stem cells. Quantifying cellular processes like mitosis in these organoids offers insights into neurodevelopmental disorders, but the manual analysis is time-consuming, and existing datasets lack specific details for brain organoid studies. We introduce

A Mathematical Model of the Cell Cycle: Exploring the Impact of Zingerone on Cancer Cell Proliferation [PDF]

arXiv
This paper presents a mathematical model that explores the interactions between Cyclin-Dependent Kinase 1 (CDK1) and the Anaphase-Promoting Complex (APC) in cancer cells. Through the analysis of a dynamical system simulating the CDK1-APC network, we investigate the system's behavior and its implications for cancer progression and potential therapeutic ...

Meiotic irregularities in Alstroemeria andina var. Venustula (Alstroemeriaceae) [PDF]

, 2007
Alstroemeria andina Phil. var. venustula (Phil.) M. Muñoz (sub nom. A. andina Phil. subsp. venustula (Phil.) Ehr. Bayer) is a perennial, small herb, 5-16 cm tall, that occurs mainly at 2,800-3,700 meters above sea level, in populations of limited ...

Air-drying of cells enables visualization of antiparallel microtubule overlaps in the spindle midzone

MethodsX, 2018
Immunofluorescence staining is used extensively to examine various types of cellular events. However, even when an antibody can detect its epitopes in western blotting, it sometimes fails to detect its epitopes when used for immunofluorescence staining ...
