Synaptonemal Complex and Microtubule Line Profiler

open access: yes, 2019
Line profiler’s purpose is to evaluate datasets in a biological/biophysical context. The software recognizes line shaped structures in image data and computes their mean position and orientation with sub-pixel accuracy. For each line a mean intensity profile is calculated.

A meiotic mystery in experimental hybrids of the eastern mole vole (Ellobius tancrei, Mammalia, Rodentia)

open access: yesВавиловский журнал генетики и селекции, 2019
Chromosomal rearrangements can lead to the formation of new stable karyotypes, nevertheless changing the architectonics of the nucleus. The differences in locations might promote Robertsonian (Rb) translocations and encourage meiotic drive in favour of ...

Defects in Meiotic Recombination Delay Progression Through Pachytene in Tex19.1-/- Mouse Spermatocytes [PDF]

open access: yes, 2018
Recombination, synapsis, chromosome segregation and gene expression are co-ordinately regulated during meiosis to ensure successful execution of this specialised cell division.

m6A Reader hnRNPA2B1 Modulates Late Pachytene Progression in Male Meiosis Through Post‐Transcriptional Control

open access: yesAdvanced Science, Volume 12, Issue 38, October 13, 2025.
As an m6A reader, hnRNPA2B1 predominantly regulates specific transcripts (e.g., Ep400, Rrs1) that are essential for chromosome organization and remodeling in an m6A‐dependent manner. Furthermore, it is demonstrated to interact with factors involved in mRNA processing and translation. This dual functionality is pivotal for ensuring the proper occurrence

Ultrastructure and Dynamics of Synaptonemal Complex Components During Meiotic Pairing and Synapsis of Standard (A) and Accessory (B) Rye Chromosomes

open access: yesFrontiers in Plant Science, 2019
During prophase I a meiosis-specific proteinaceous tripartite structure, the synaptonemal complex (SC), forms a scaffold to connect homologous chromosomes along their lengths.

Evolutionary history of the mammalian synaptonemal complex [PDF]

open access: yesChromosoma, 2016
The synaptonemal complex (SC), a key structure of meiosis that assembles during prophase I, has been initially described 60 years ago. Since then, the structure has been described in many sexually reproducing organisms. However, the SC protein components were characterized in only few model organisms.

CDK2 regulates nuclear envelope protein dynamics and telomere attachment in mouse meiotic prophase [PDF]

open access: yes, 2015
In most organisms, telomeres attach to the nuclear envelope at the onset of meiosis to promote the crucial processes of pairing, recombination and synapsis during prophase I.

EP300‐interacting inhibitor of differentiation 3 is required for spermatogenesis in mice

open access: yesAndrology, Volume 13, Issue 7, Page 1901-1912, October 2025.
Abstract Background Mammalian spermatogenesis is a highly complex process of cell proliferation, meiosis, and differentiation. A series of genes are expressed in an orderly and precise manner to ensure spermatogenesis, with chromatin undergoing intricate changes throughout.

Comparative Genomics of Sex‐Determination‐Related Genes Reveals Shared Evolutionary Patterns Between Bivalves and Mammals, but Not Fruit Flies

open access: yesMolecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT The molecular basis of sex determination (SD), while being extensively studied in model organisms, remains poorly understood in many animal groups. Bivalves, a diverse class of molluscs with a variety of reproductive modes, represent an ideal yet challenging clade for investigating SD and the evolution of sexual systems.

SCRE serves as a unique synaptonemal complex fastener and is essential for progression of meiosis prophase I in mice

open access: yesNucleic Acids Research, 2019
Meiosis is a specialized cell division for producing haploid gametes from diploid germ cells. During meiosis, synaptonemal complex (SC) mediates the alignment of homologs and plays essential roles in homologous recombination and therefore in promoting ...
