Summary: The study identified that in a specific cell line system, cisplatin resistant cells had less damage but similar repair kinetics. Through mapping gene expression changes, 56 upregulated genes were identified that could potentially impact the response to cisplatin.

Summary: In this study, CIP2A is identified as a protein that interacts with TOPBP1 and specifically regulates its localization in mitosis. Cells lacking CIP2A show increased radio-sensitivity, micronuclei formation, and chromosomal instability.

Summary: DNA is crucial for organism development and function. MiRNA, a type of non-coding RNA, may play an important role in the DNA damage response by influencing processes like cell cycle, DNA repair, and apoptosis, thereby impacting genomic stability and tumorigenesis.

Summary: Exposure to environmental ionizing radiation, particularly high-LET radiation, can induce clustered DNA damage that is challenging to repair. Understanding the role of chromatin in the repair process is essential for assessing the effects of radiation exposure.

Summary: Copper is essential but over-exposure can lead to adverse health effects. CuSO4 was found to induce spermatogenesis disorder through oxidative stress-mediated DNA damage and apoptosis, impairing male reproductive function.

Summary: The XR-seq method is widely used for mapping nucleotide excision repair genome-wide. It captures and sequences excised oligomers carrying DNA damage, and aligns their sequences to the genome. Researchers have successfully used ultraviolet light-irradiated plasmids as substrates for repair experiments in Escherichia coli and mammals, and found common excision product characteristics in both systems. This approach helps understand the effects of epigenetics and other cellular factors on DNA repair.

Summary: The translated article discusses the complex relationship between DNA replication stress, DDR signaling, and genome integrity in mammalian cells, with a focus on the role of chromatin disposition as an important modulator of DNA repair. It reviews recent data on chromatin restoration and epigenetic re-establishment after DNA replication stress.

Summary: The deregulated DNA damage response network is associated with the onset and progression of lung cancer. This study found that lung cancer patients have higher levels of endogenous DNA damage, which may be caused by oxidative stress and defective DNA repair mechanisms. The findings suggest that oxidative stress and DDR-related aberrations contribute to the accumulation of endogenous DNA damage in lung cancer patients.

Summary: The preimplantation period of embryogenesis plays a crucial role in mammalian development, and cellular abnormalities during this period are the main cause of fetal developmental disorders. Research has found that DNA damage induced before DNA synthesis can significantly affect the preimplantation development of the embryo, and the extent of DNA damage is related to this developmental ability. Although one-cell embryos can correct the first cleavage cycle, a segregation disorder of condensed chromatin after the first cleavage can result in the formation of micronuclei.

Summary: Neuronal activity poses a risk to genome stability, but neurons have a specialized DNA repair mechanism that protects against damage caused by activity. This mechanism involves a specific complex called NPAS4-NuA4, which repairs DNA double-strand breaks and protects regulatory elements from somatic mutations. Disruption of this complex can lead to neurodevelopmental disorders, neurodegeneration, and reduced lifespan.

Summary: The chromatin-associated AAA+ ATPases Tip48 and Tip49 are crucial for various nuclear events and frequently overexpressed in human cancers. Loss of Tip49 triggers p53-dependent apoptosis and inhibits leukemia development. The compound DS-4950, which inhibits the ATPase activity of Tip48/49, effectively reduces tumor burden and improves survival in leukemia models. These findings suggest that Tip48/49 ATPases are functionally necessary and therapeutically targetable for the treatment of human cancers.

Summary: Eukaryotic nuclei rely on multiple repair pathways to accurately repair DNA damage, particularly in chromatin domains enriched for repetitive DNA sequences. Tailored repair mechanisms are necessary to maintain genome stability in these domains.
