Genetics of mammalian meiosis: regulation, dynamics and impact on fertility

Abstract: Meiosis is an essential stage in gamete formation in all sexually reproducing organisms. Studies of mutations in model organisms and of human haplotype patterns are leading to a clearer understanding of how meiosis has adapted from yeast to humans, the genes that control the dynamics of chromosomes during meiosis, and how meiosis is tied to gametic success. Genetic disruptions and meiotic errors have important roles in infertility and the aetiology of developmental defects, especially aneuploidy. An understand… Show more

“…[16][17][18][19] Nevertheless there are several key processes that take place during meiosis that are critical for gamete formation and correct chromosome segregation, these will be reviewed in detail along with their role in male infertility. The vast majority of meiotic genes have been identified in yeast and murine models which have provided strong evidence of the catastrophic effects on fertility if meiotic genes are perturbed.…”

“…Dans leur récente étude des conséquen-ces de l'invalidation conditionnelle du gène Foxl2, les équipes de Mathias Treier et Robin Lovell-Badge démontrent que cette opposition mâle/femelle perdure même dans un tissu totalement diffé-rencié comme l'est l'ovaire adulte de souris [1].…”

“…La recombinaison méiotique a également pour conséquence de provoquer un réassortiment des allè-les dans le génome, ce qui contribue à générer de la diversité génétique. Le mécanisme moléculaire de la recombinaison méiotique, disséqué chez la levure Saccharomyces cerevisiae, est conservé au moins dans ses grandes lignes chez les eucaryotes supérieurs [1]. La première étape moléculaire est la formation de cassures double-brin de l'ADN catalysées par la protéine Spo11 [13].…”

“…A small number of DSBs form crossover recombinations, and the majority of DSBs are repaired as non‐crossover recombinations in spermatocytes 17, 18. These processes involve a number of meiotic‐specific and ubiquitously expressed nuclear proteins, such as γH2AX, RAD51, RAD18, DMC1, BRCA1 and MLH1 19, 20, 21, 22. These proteins are co‐ordinately recruited to DSB sites to facilitate DNA DSB repair via homologous recombination.…”

“…These proteins are co‐ordinately recruited to DSB sites to facilitate DNA DSB repair via homologous recombination. Defects in DNA DSB repair can cause chromosome mis‐segregation underling aneuploidy‐related pathologies or meiotic arrest of spermatocytes leading to male infertility 17, 20, 23, 24…”
