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

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 ...

Privación sensorial temprana durante el neurodesarrollo y sus consecuencias cognitivas
Medicina U.P.B., 2020 La aparición progresiva de habilidades sensoriales, motoras y cognitivo-afectivas en el humano a lo largo de su desarrollo es un reflejo de cambios fisiológicos que se gestan al interior del sistema nervioso.

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

BIO-PROTOCOL, 2013 Many environmental agents induce double-strand breaks (DSBs) in DNA. Unrepaired or improperly repaired DSBs can lead to cell death or cancer. Nonhomologous end joining is the primary DNA double-strand break repair pathway in eukaryotes. During NHEJ pathway, several proteins recognize and bind DNA ends, bring the ends in a synaptic complex and, finally,

Science Advances, 2020 Synaptonemal complex assembly depends on multivalent protein interactions between SYCE1 and SIX6OS1. Meiotic reductional division depends on the synaptonemal complex (SC), a supramolecular protein assembly that mediates homologous chromosomes synapsis ...
