Interplay between synaptonemal complex, homologous recombination, and centromeres during mammalian meiosis. [PDF]

PLoS Genetics, 2012
The intimate synapsis of homologous chromosome pairs (homologs) by synaptonemal complexes (SCs) is an essential feature of meiosis. In many organisms, synapsis and homologous recombination are interdependent: recombination promotes SC formation and SCs ...

Dynamic localization of SMC5/6 complex proteins during mammalian meiosis and mitosis suggests functions in distinct chromosome processes [PDF]

, 2016
et al.Four members of the structural maintenance of chromosome (SMC) protein family have essential functions in chromosome condensation (SMC2/4) and sister-chromatid cohesion (SMC1/3). The SMC5/6 complex has been implicated in chromosome replication, DNA

BRCA1-BARD1 associate with the synaptonemal complex and pro-crossover factors and influence RAD-51 dynamics during Caenorhabditis elegans meiosis

PLoS Genetics, 2018
During meiosis, the maternal and paternal homologous chromosomes must align along their entire length and recombine to achieve faithful segregation in the gametes. Meiotic recombination is accomplished through the formation of DNA double-strand breaks, a

An atomic force microscopical study of the synaptonemal complex [PDF]

Micron, 1993
The chromosomal structure which is specific for meiosis, the synaptonemal complex (SC), plays a major role in chromosome pairing and the recombination of genetic material. The SC was studied using atomic force microscopy (AFM). The results of this study confirm the results of light and electron microscopic studies of the SC.

METTL16 is Required for Meiotic Sex Chromosome Inactivation and DSB Formation and Recombination during Male Meiosis

Advanced Science, Volume 12, Issue 3, January 20, 2025.
METTL16 predominantly controls the expression of critical meiotic genes essential for DSB formation and recombination in early meiotic spermatocytes and is involved in the expansion of DNA damage response (DDR) factors and epigenetic modifications in the XY body for the establishment and maintenance of meiotic sex chromosome inactivation (MSCI) in ...

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

Вавиловский 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 ...

Mixing and Matching Chromosomes during Female Meiosis

Cells, 2020
Meiosis is a key event in the manufacturing of an oocyte. During this process, the oocyte creates a set of unique chromosomes by recombining paternal and maternal copies of homologous chromosomes, and by eliminating one set of chromosomes to become ...

Intercellular Migration of Centrioles in the Germarium of \u3cem\u3eDrosophila melanogaster\u3c/em\u3e. An Electron Microscopic Study [PDF]

, 1970
A cluster of centrioles has been found in the early Drosophila oocyte. Since the oocyte is connected to 15 nurse cells by a system of intercellular bridges or ring canals, the possibility that the cluster of centrioles arose in the germarium from an ...

Chromosome segregation in plant meiosis [PDF]

, 2014
Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

Prenatal Silicon Dioxide Nanoparticles Exposure Reduces Female Offspring Fertility Without Affecting Males

Advanced Science, Volume 12, Issue 3, January 20, 2025.
Prenatal exposure to silicon dioxide nanoparticles (SiO2 NPs) caused subfertility in female offspring, reducing ovulation, ovarian reserve, and litter size, while male offspring remained unaffected. Mechanistic analysis revealed disrupted meiotic recombination and increased oocyte apoptosis in females. COOH‐functionalized SiO2 NPs showed minimal impact
