DNA double-strand break end synapsis by DNA loop extrusion
bioRxiv, 2021 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.

Evidence that masking of synapsis imperfections counterbalances quality control to promote efficient meiosis. [PDF]
PLoS Genetics, 2013 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 ...

Heat stress interferes with formation of double-strand breaks and homolog synapsis.
Plant Physiology, 2021 Meiotic recombination (MR) drives novel combinations of alleles and contributes to genomic diversity in eukaryotes. In this study, we showed that heat stress (36°C-38°C) over the fertile threshold fully abolished crossover formation in Arabidopsis ...

The Absence of Caspase-8 in the Dopaminergic System Leads to Mild Autism-like Behavior
Frontiers in Cell and Developmental Biology, 2022 In the last decade, new non-apoptotic roles have been ascribed to apoptotic caspases. This family of proteins plays an important role in the sculpting of the brain in the early stages of development by eliminating excessive and nonfunctional synapses and

Frontiers in Plant Science, 2020 Hybridization and polyploidization are major driving forces in plant evolution. Allopolyploids can be occasionally formed from a cross between distantly related species but often suffer from chromosome instability and infertility. xBrassicoraphanus is an

Regulation of microglia phagocytosis and potential involvement of exercise
Frontiers in Cellular Neuroscience, 2022 Microglia are considered the main phagocytic cells in the central nervous system, remodeling neural circuits by pruning synapses during development. Microglial phagocytosis is also a crucial process in maintaining adult brain homeostasis and clearing ...
