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

The Role of Foundational Relations in the Alignment of Biomedical Ontologies [PDF]
The Foundational Model of Anatomy (FMA) symbolically represents the structural organization of the human body from the macromolecular to the macroscopic levels, with the goal of providing a robust and consistent scheme for classifying anatomical entities

TRIP13PCH-2 promotes Mad2 localization to unattached kinetochores in the spindle checkpoint response. [PDF]
The spindle checkpoint acts during cell division to prevent aneuploidy, a hallmark of cancer. During checkpoint activation, Mad1 recruits Mad2 to kinetochores to generate a signal that delays anaphase onset.

Diploid origins and early genome stabilization in the allotetraploid Arabidopsis suecica
Summary Polyploidization, followed by genome downsizing, is a recurrent evolutionary cycle that dramatically reshapes genome structure. Newly formed polyploids must quickly adjust their cell division machinery to maintain stable chromosome inheritance, while long‐term stabilization involves rediploidization, returning the genome to a diploid‐like state.

The ubiquitin proteasome system regulates meiotic recombination in yeast through its association with the synaptonemal complex, a 'zipper'-like structure that holds homologous chromosome pairs in synapsis during meiotic prophase I.

The repair of SPO11-dependent double-strand breaks (DSBs) by homologous recombination (HR) ensures the correct segregation of homologous chromosomes. In yeast and human, RAD17 is involved in DNA damage checkpoint control and DSB repair.

Mixing and Matching Chromosomes during Female Meiosis
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 ...

Synaptonemal complex protein 3 is a prognostic marker in cervical cancer. [PDF]
Synaptonemal complex protein 3 (SCP3), a member of Cor1 family, is up-regulated in various cancer cells; however, its oncogenic potential and clinical significance has not yet been characterized.

Meiotic nuclear divisions in budding yeast require PP2ACdc55-mediated antagonism of Net1 phosphorylation by Cdk [PDF]
During meiosis, one round of deoxyribonucleic acid replication is followed by two rounds of nuclear division. In Saccharomyces cerevisiae, activation of the Cdc14 early anaphase release (FEAR) network is required for exit from meiosis I but does not lead

Eukaryogenesis From FECA to LECA: Radical Steps Along the Way
How did the last eukaryotic common ancestor (LECA) population evolve? Recent evidence shows an Asgard archaeon‐like organism acquiring a bacterium, the future mitochondrion, going from symbiosis to endosymbiosis. I postulate that almost all salient LECA characteristics could have resulted from the ensuing enhanced ATP generation and internal reactive ...
