The vast majority of multicellular organisms reproduce using sexual reproduction, which requires the production of haploid gametes. These gametes are produced by meiosis, a specialized cell division during which one round of DNA replication is followed by two rounds of chromosome segregation, Meiosis I (MI) and Meiosis II (MII). This imbalance between rounds of DNA replication and chromosome segregation causes diploid cells to produce haploid gametes. In contrast, mitotically-dividing cells maintain ploidy by alternating between rounds of replication and segregation. It is unclear how meiosis accomplishes two sequential chromosome segregation events without an intervening round of DNA replication. In mitotic cells, both DNA replication and chromosome segregation are regulated by oscillations of cyclin-dependent kinase (CDK) activity. Both events initiate during G1 due to the associated low CDK-activity state, and both events are completed later in the cell cycle due to increased CDK activity. During meiosis, uncoupling replication and segregation presents a unique problem. After completion of MI, CDK activity decreases and then increases to drive MII chromosome segregation. However, DNA replication must remain inhibited between MI and MII. Given that an oscillation of CDK activity is sufficient for genome re-duplication in mitotic cells, I sought to understand how meiotic cells prevent DNA replication while resetting the chromosome segregation program. In this thesis, I show that meiotic cells inhibit two distinct steps of DNA replication: (1) loading of the replicative helicase onto replication origins, and (2) activation of the replicative helicase. CDK and the meiosis-specific kinase Ime2 cooperatively inhibit helicase loading during the meiotic divisions, and their simultaneous inhibition causes inappropriate helicase reloading. Further studies of Ime2 revealed two mechanisms by which it inhibits this process. First, I showed that Ime2-phosphorylation of the helicase directly inhibits its loading onto origins. Second, Ime2 cooperated with CDK to transcriptionally and proteolytically repress Cdc6, an essential helicase-loading protein. In addition, I found that meiotic cells use CDK and the polo-like kinase Cdc5 to promote degradation of Sld2, an essential helicase-activation protein. Together, these data demonstrate that multiple kinases inhibit both helicase loading and activation between MI and MII, thereby ensuring a reduction in ploidy.

Texto completoIn order to protect germinal cells from genomic instability, surveillance mechanisms ensure that meiosis occurs properly. In mammals, spermatocytes that display recombination or sex body defects experience an arrest at pachytene stage. Previous studies from our lab described that the MRE11 complex-ATM-CHK2 pathway activates the recombination-dependent arrest in the presence of unrepaired double strand breaks (DSBs). In this work we aimed to identify if p53 family members, which are putative targets of ATM and CHK2, participate in the activation of the recombination-dependent arrest. As a genetic approach, we bred double mutant mice carrying a mutation of a member of the p53 family (p53, TAp63, p73) in a Trip13 defective background. Trip13 mutation causes recombination defects, which activate the recombination-dependent arrest in pachytene-stage spermatocytes. Thus, we studied how the absence of p53 family members affected the arrest phenotype of Trip13mod/mod spermatocytes. Our data showed that p53 and TAp63 deficiency, but not p73, allowed spermatocytes to progress further into late pachynema, despite accumulating numerous unrepaired DBSs. In addition, lack of p53 or TAp63 resulted in a decrease of apoptotic spermatocytes at early pachytene stage. Therefore, our results indicate that p53 and TAp63 are responsible to activate the recombination-dependent arrest in mouse spermatocytes. Even though, double mutant spermatocytes still arrested at pachytene stage. To study if double mutant spermatocytes were arresting due to the activation of the sex body deficient arrest we analyzed MSCI functionality in Trip13 mutants. Thus, by bypassing the recombination-dependent arrest has allowed us to elucidate a role for TRIP13 protein in meiotic silencing, which consequently triggers apoptosis in double mutants at late pachytene stage due to sex body impairment. These results infer that the recombination-dependent and the sex-body deficient arrest are activated by two genetically separated mechanisms. From the observation that TRIP13 is required to implement MSCI silencing, we performed an exhaustive analysis of transcription in Trip13 mutants. Our results suggested that RNA expression in Trip13 mutants was increased in early meiotic stage spermatocytes, assessed by EU-labeling RNA and phosphorylated(S2)-RNA polymerase II. Moreover, RNA sequencing data highlighted the observation that sex chromosome genes and pre-meiotic genes are overexpressed in Trip13 mutants, suggesting that TRIP13 is required to maintain the expression of these genes at low levels. Overall, the data presented in this work contributes to the understanding on how surveillance mechanisms control several crucial steps of meiotic prophase progression in mammalian spermatocytes.

Texto completoMeiotic crossovers (CO) are formed by reciprocal exchange of genetic material between the homologous chromosomes. CO generate genetic diversity and are essential for the proper segregation of chromosomes during meiosis in most eukaryotes. Despite their significance and a large excess of CO precursors, CO number is very low in vast majority of species (typically one to three per chromosome pair). This indicates that COs are tightly regulated but the underlying mechanisms of this limit remain elusive. In order to identify genes that limit COs, a genetic screen was performed in Arabidopsis thaliana. This led to the identification and characterization of several anti-CO factors belonging to three different pathways: (i) The FANCM helicase and its cofactors (ii) The AAA-ATPase FIDGETIN-LIKE-1 (FIGL1) (iii) The RECQ4 -Topoisomerase 3α-RMI1 complex. The first objective was to understand the functional relationship between these three pathways and to address following questions: (1) how far can we increase recombination when combining mutations in FANCM, FIGL1 and RECQ4? We show that the highest increase in recombination was obtained in figl1 recq4, reaching to 7.5 fold the wild type level, on average genome wide. (2) How is the distribution of recombination events genome wide in mutants? The increased CO frequency in the mutants was not uniform throughout the genome. CO frequency rises from the centromere to telomeres, with distal intervals having highest COs (3) is the recombination frequency increase same in both male and female? In Arabidopsis wild type, male has higher recombination than female meiosis. In contrast, in recq4 and recq4 figl1, female recombination was higher than male. This suggests that certain constraints that apply to CO formation in wild type females are relieved in the mutant. By continuing the same genetic screen, a novel anti-CO mutant was identified. The second objective was to identify and functionally characterize the corresponding gene. Genetic mapping and protein interaction studies led to the identification of a factor that directly interacts with FIGL1 and appears to form a conserved complex both in Arabidopsis and humans. Hence, the factor was named FLIP (Fidgetin-like-1 interacting protein). Recombination frequency is increased in flip, confirming that FLIP limit COs. Epistasis studies showed that FLIP and FIGL1 act in same pathway. Further, FIGL1/FLIP proteins of Arabidopsis and humans directly interact with the recombinases RAD51 and DMC1 which catalyze a crucial step of homologous recombination, the inter homolog strand invasion. In addition flip like figl1 modifies dynamics of DMC1. We thus propose a model wherein the FLIP-FIGL1 complex negatively regulates RAD51/DMC1 to limit CO formation. Studying the conserved FIGL1-FLIP complex led to the identification of a novel mode of regulation of recombination, that likely acts at the key step of homologous strand invasion. Further the unprecedented level of CO increase in recq4figl1 in hybrids could be of great interest for crop improvement, allowing the production of novel allele combinations
