The SUN1-SPDYA interaction plays an essential role in meiosis prophase I

Nature Communications, 2021
Chromosomes pair and synapse with their homologous partners to segregate correctly at the first meiotic division. Association of telomeres with the LINC (Linker of Nucleoskeleton and Cytoskeleton) complex composed of SUN1 and KASH5 enables telomere-led ...

Cyclins and CDKs in the regulation of meiosis-specific events

Frontiers in Cell and Developmental Biology, 2022
How eukaryotic cells control their duplication is a fascinating example of how a biological system self-organizes specific activities to temporally order cellular events.

Maintenance DNA methylation in pre-meiotic germ cells regulates meiotic prophase by facilitating homologous chromosome pairing.

Development, 2021
Heterochromatin-related epigenetic mechanisms, such as DNA methylation, facilitate pairing of homologous chromosomes during the meiotic prophase of mammalian spermatogenesis.

Nucleolus disassembly and distribution of segregated nucleolar material in prophase of root-tip meristematic cells in Triticum aestivum L. [PDF]

Archives of Biological Sciences, 2015
This paper presents details of the process of nucleolar disassembly, studied by conventional transmission electron microscopy (TEM) in wheat root cells. In early prophase, chromatin condensation and irregular nucleolar morphology are observed, with many ...

Meiosis-specific ZFP541 repressor complex promotes developmental progression of meiotic prophase towards completion during mouse spermatogenesis

Nature Communications, 2021
During spermatogenesis, meiosis is accompanied by a robust alteration in gene expression and chromatin status. However, it remains elusive how the meiotic transcriptional program is established to ensure completion of meiotic prophase.

Where, When, and How? Integrating Spatiotemporal Cues in Cell Division. [PDF]

Bioessays
Accurate chromosome segregation during mitosis depends on the spatial and temporal regulation of spindle assembly, kinetochore‐microtubule attachment, and checkpoint signaling. Here, we highlight how mitotic chromosomes can serve as dynamic hubs that integrate molecular cues to coordinate spindle organization and timing, ensuring faithful genome ...

FBXO47 is essential for preventing the synaptonemal complex from premature disassembly in mouse male meiosis

iScience, 2022
Summary: Meiotic prophase I is a prolonged G2 phase that ensures the completion of numerous meiosis-specific chromosome events. During meiotic prophase I, homologous chromosomes undergo synapsis to facilitate meiotic recombination yielding crossovers. It

A dynamic population of prophase CENP-C is required for meiotic chromosome segregation.

PLoS Genetics, 2023
The centromere is an epigenetic mark that is a loading site for the kinetochore during meiosis and mitosis. This mark is characterized by the H3 variant CENP-A, known as CID in Drosophila.

SKP1 drives the prophase I to metaphase I transition during male meiosis

Science Advances, 2020
SKP1 coordinates chromosome synapsis and meiotic recombination with progression through the first meiotic cell division in mouse. The meiotic prophase I to metaphase I (PI/MI) transition requires chromosome desynapsis and metaphase competence acquisition.
