AI Article Synopsis

  • Recent studies show that common fragile sites (CFSs), once thought to cause chromosome rearrangements in cancers, are not commonly involved in major translocations or rearrangements.
  • There's been a shift in focus to understanding how CFS instability contributes to genome instability and affects cancer development.
  • New findings highlight that CFSs can lead to specific copy number changes, impacting the genetic makeup of various cancers.

Article Abstract

Ever since initial suggestions that instability at common fragile sites (CFSs) could be responsible for chromosome rearrangements in cancers, CFSs and associated genes have been the subject of numerous studies, leading to questions and controversies about their role and importance in cancer. It is now clear that CFSs are not frequently involved in translocations or other cancer-associated recurrent gross chromosome rearrangements. However, recent studies have provided new insights into the mechanisms of CFS instability, their effect on genome instability, and their role in generating focal copy number alterations that affect the genomic landscape of many cancers.

Background: Access to healthcare is a major challenge in South Sudan, but evidence on the factors influencing health seeking behaviour (HSB) and the magnitude of their effect is limited. This study aims to identify which determinants are associated with seeking care for perceived health needs and with seeking care at private or public healthcare facilities in South Sudan.

Methods: A cross-sectional household survey was conducted in three purposefully-selected states (Central Equatoria, Western Equatoria and Warrap).

Long AT repeat tracts form non-B DNA structures that stall DNA replication and cause chromosomal breakage. AT repeats are abundant in human common fragile sites (CFSs), genomic regions that undergo breakage under replication stress. Using an in vivo yeast model system containing AT-rich repetitive elements from human CFS FRA16D, we find that DNA polymerase zeta (Pol ζ) is required to prevent breakage and subsequent deletions at hairpin and cruciform forming (AT/TA)n sequences, with little to no role at an (A/T)28 repeat or a control non-structure forming sequence.

Background: For complete disruption of the posterolateral corner (PLC) structures, operative treatment is most commonly advocated, as nonoperative treatment has higher rates of persistent lateral laxity and posttraumatic arthritis. Some studies have shown that acute direct repair results in revision rates upwards of 37% to 40% compared with 6% to 9% for initial reconstruction. In a recent study assessing the outcomes of acute repair of PLC avulsion injuries with 2 to 7 years of follow-up, patients with adequate tissue were shown to have a much lower failure rate than previously documented.

Article Synopsis
  • Organic ultraviolet filters (OUVFs) are commonly found in sunscreen products and have been detected in coral reef ecosystems, particularly in tropical regions like Hainan Island, raising concerns about their ecological impact on coral reefs.
  • A study analyzed 14 OUVFs across 24 coral species, seawater, and sediment samples, finding all filters present in every sample location and highlighting species-specific accumulation levels, with benzophenone-3 (BP-3) and 4-methylbenzylidene camphor (4-MBC) as the most concentrated.
  • The analysis showed that higher levels of OUVFs correlate with tourist activities, particularly in areas like Sanya, indicating significant risks to coral ecosystems due to sunscreen usage, especially during coral

Transcription as a double-edged sword in genome maintenance.

FEBS Lett

December 2024

Department of Biochemistry and Molecular Biology, Hollings Cancer Center, Medical University of South Carolina, Charleston, SC, USA.

Genome maintenance is essential for the integrity of the genetic blueprint, of which only a small fraction is transcribed in higher eukaryotes. DNA lesions occurring in the transcribed genome trigger transcription pausing and transcription-coupled DNA repair. There are two major transcription-coupled DNA repair pathways.
