Restarting Stalled Replication Forks02:37

Restarting Stalled Replication Forks

DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart, a...
DNA Damage can Stall the Cell Cycle02:36

DNA Damage can Stall the Cell Cycle

In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Meiosis II02:02

Meiosis II

Meiosis II entails cell division and segregation of the sister chromatids, resulting in the production of four unique haploid gametes. The steps for meiosis II are similar to mitosis, except that meiosis II occurs in haploid cells, whereas mitosis occurs in diploid cells.
The timing and cell division patterns of meiosis differ between males and females. In male meiosis, the centrosomes are part of the formation of the meiotic spindle. However, in oocytes, including that of humans, Drosophila,...
Meiosis II01:57

Meiosis II

Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each containing...

Area of Science:

  • Molecular Biology
  • Genetics
  • Reproductive Biology

Background:

  • RAD18 is an E3 ubiquitin ligase involved in DNA repair and replication damage bypass in somatic cells.
  • Meiosis involves programmed DNA double-strand breaks (DSBs) crucial for homologous recombination, but their repair requires specific mechanisms.

Purpose of the Study:

  • To investigate the role of RAD18 in male meiosis.
  • To determine RAD18's function in repairing meiotic DSBs induced by SPO11.
  • To elucidate RAD18's involvement in sex chromosome inactivation.

Main Methods:

  • Utilized Rad18-knockdown mice to study testicular phenotype.
  • Investigated RAD18 recruitment to meiotic DSBs and XY body chromatin.
  • Analyzed the impact of RAD18 on histone methylation and HR6A/HR6B association.

Main Results:

  • RAD18 is recruited to a subset of persistent meiotic DSBs and XY body chromatin.
  • RAD18 mediates the chromatin association of HR6A and HR6B at the XY body.
  • RAD18 regulates H3K4 dimethylation and meiotic sex chromosome inactivation, similar to HR6B.

Conclusions:

  • RAD18 plays a significant role in male meiosis, particularly in DSB repair and sex chromosome inactivation.
  • RAD18 and HR6B are essential for the efficient repair of a specific subset of meiotic DSBs.
