SnapShot: Meiosis – Prophase I
Cell, 2020 Meiosis is the specialized cell division that generates haploid gametes and is therefore essential for sexual reproduction. This SnapShot encompasses key events taking place during prophase I of meiosis that are required for achieving proper chromosome segregation and highlights how these are both conserved and diverged throughout five different ...

Dual pathway spindle assembly increases both the speed and the fidelity of mitosis [PDF]
Biology Open, 2011 Summary Roughly half of all animal somatic cell spindles assemble by the classical prophase pathway, in which the centrosomes separate ahead of nuclear envelope breakdown (NEBD).

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.

PLoS Genetics, 2016 During prophase of the first meiotic division (prophase I), chromatin dynamically reorganises to recombine and prepare for chromosome segregation. Histone modifying enzymes are major regulators of chromatin structure, but our knowledge of their roles in ...

Early programming of the oocyte epigenome temporally controls late prophase I transcription and chromatin remodelling [PDF]
Nature Communications, 2016 Oocytes are arrested for long periods of time in the prophase of the first meiotic division (prophase I). As chromosome condensation poses significant constraints to gene expression, the mechanisms regulating transcriptional activity in the prophase I ...

Somatic Kitl promotes mTOR to facilitate prophase I of meiosis in female embryonic gonads [PDF]
Cell Death and DiseaseHomologous synapsis and recombination are the central events that take place in the prophase I of meiosis. Signaling that promotes the germ cell differentiation and prophase I remains elusive.

Mechanism and Regulation of Rapid Telomere Prophase Movements in Mouse Meiotic Chromosomes
Cell Reports, 2015 Telomere-led rapid prophase movements (RPMs) in meiotic prophase have been observed in diverse eukaryote species. A shared feature of RPMs is that the force that drives the chromosomal movements is transmitted from the cytoskeleton, through the nuclear ...

Loss of meiotic double strand breaks triggers recruitment of recombination-independent pro-crossover factors in C. elegans spermatogenesis. [PDF]
PLoS GeneticsA key event in meiosis is the conversion of a small subset of double strand breaks into interhomolog crossovers. In this study, we demonstrate that Caenorhabditis elegans male spermatogenesis has less robust mechanisms than hermaphrodite oogenesis in ...

Prophase Poisoning by Chemical Agents
Caryologia, 1949 RIASSUNTOIn occasione della comparsa di un recente lavoro sull'avvelenamento della profase (Erickson e Rosen 1949), l'A. rivendica la priorita della scoperta di questo singolare effetto citologico ed enumera recenti lavori di citologia sperimentale nei quali e accennato, ma non interpretato, l'avvelenamento della profase.
