Shock and Vibration, 2021 In order to reveal the influence of prophase stress levels on the fatigue damage characteristics of granite, uniaxial fatigue tests of granite with different prophase stress levels were carried out on the basis of the MTS 815.04 rock mechanics test ...

Regulation of Meiotic Prophase One in Mammalian Oocytes
Frontiers in Cell and Developmental Biology, 2021 In female mammals, meiotic prophase one begins during fetal development. Oocytes transition through the prophase one substages consisting of leptotene, zygotene, and pachytene, and are finally arrested at the diplotene substage, for months in mice and ...

Meioc maintains an extended meiotic prophase I in mice. [PDF]
PLoS Genetics, 2017 The meiosis-specific chromosomal events of homolog pairing, synapsis, and recombination occur over an extended meiotic prophase I that is many times longer than prophase of mitosis.

Meiotic chromosome dynamics and double strand break formation in reptiles
Frontiers in Cell and Developmental Biology, 2022 During meiotic prophase I, tightly regulated processes take place, from pairing and synapsis of homologous chromosomes to recombination, which are essential for the generation of genetically variable haploid gametes.

Actomyosin-dependent cortical dynamics contributes to the prophase force-balance in the early Drosophila embryo. [PDF]
PLoS ONE, 2011 The assembly of the Drosophila embryo mitotic spindle during prophase depends upon a balance of outward forces generated by cortical dynein and inward forces generated by kinesin-14 and nuclear elasticity. Myosin II is known to contribute to the dynamics

Life, 2023 Transcription is known to be substage-specific in meiotic prophase I. If transcription is reactivated in the mid pachytene stage in mammals when synapsis is completed, then this process is observed in the zygotene stage in insects.

Testing of mitosis and meiosis in female and male gametes
Андрология и генитальная хирургия, 2017 Method of quantitative evaluation of the immature germ cells, their pathology in mitosis and meiosis (in semen, embryo and fetal ovaries, of gonad biopsies or fragments of sectioned material) is informative method and should be introduced into the ...

Genetic control of meiosis surveillance mechanisms in mammals
Frontiers in Cell and Developmental Biology, 2023 Meiosis is a specialized cell division that generates haploid gametes and is critical for successful sexual reproduction. During the extended meiotic prophase I, homologous chromosomes progressively pair, synapse and desynapse. These chromosomal dynamics

A Gene Regulatory Program for Meiotic Prophase in the Fetal Ovary. [PDF]
PLoS Genetics, 2015 The chromosomal program of meiotic prophase, comprising events such as laying down of meiotic cohesins, synapsis between homologs, and homologous recombination, must be preceded and enabled by the regulated induction of meiotic prophase genes.

Condensation patterns of prophase/prometaphase chromosome are correlated with H4K5 histone acetylation and genomic DNA contents in plants. [PDF]
PLoS ONE, 2017 Mitotic prophase chromosome condensation plays an essential role in nuclear division being therefore regulated by highly conserved mechanisms. However, degrees of chromatin condensation in prophase-prometaphase cells may vary along the chromosomes ...
