Chromosome segregation in plant meiosis [PDF]
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

Transcriptomic profile of epileptic children treated with ketogenic therapies [PDF]
Background: Ketogenic dietary therapies (KDT) are used as a treatment in childhood epilepsy. However, their mechanism has not yet been established. The main objective of this study was to determine the changes in the transcriptomic profile induced by ...

The Ecm11-Gmc2 complex promotes synaptonemal complex formation through assembly of transverse filaments in budding yeast [PDF]
During meiosis, homologous chromosomes pair at close proximity to form the synaptonemal complex (SC). This association is mediated by transverse filament proteins that hold the axes of homologous chromosomes together along their entire length. Transverse

Structural maturation of SYCP1-mediated meiotic chromosome synapsis by SYCE3
SYCP1 structures are conformationally remodeled by molecular adapter SYCE3 to assemble into the supramolecular synaptonemal complex that mediates chromosome synapsis and facilitates crossover formation in meiosis.

SYCP1 head-to-head assembly is required for chromosome synapsis in mouse meiosis
In almost all sexually reproducing organisms, meiotic recombination and cell division require the synapsis of homologous chromosomes by a large proteinaceous structure, the synaptonemal complex (SC).

DNA double-strand break end synapsis by DNA loop extrusion
DNA double-strand breaks (DSBs) occur every cell cycle and must be efficiently repaired. Non-homologous end joining (NHEJ) is the dominant pathway for DSB repair in G1-phase.

Peroxisomal Proliferator-Activated Receptor β/δ Deficiency Induces Cognitive Alterations
Peroxisome proliferator-activated receptor β/δ (PPARβ/δ), the most PPAR abundant isotype in the central nervous system, is involved in microglial homeostasis and metabolism, whose disturbances have been demonstrated to play a key role in memory ...

Meiotic homolog synapsis is essential to ensure accurate segregation of chromosomes during meiosis. In C. elegans, proper regulation of synapsis and a checkpoint that monitors synapsis relies on the spindle checkpoint components, Mad1 and Mad2, and ...

Evidence that masking of synapsis imperfections counterbalances quality control to promote efficient meiosis. [PDF]
Reduction in ploidy to generate haploid gametes during sexual reproduction is accomplished by the specialized cell division program of meiosis. Pairing between homologous chromosomes and assembly of the synaptonemal complex at their interface (synapsis ...
