Article Synopsis
  • - Chromosome instability (CIN) is common in tumors, often driven by the breakage-fusion-bridge (BFB) cycle, but detailed mechanisms are still unclear.
  • - Researchers used a nuclease-dead Cas9 (dCas9) with a telomere-specific guide RNA to model the BFB cycle, finding that targeting telomeres causes DNA replication stress and increased DNA damage.
  • - The study revealed significant chromosome end fusions and other structures related to chromosome bridges, highlighting multiple DNA repair pathways involved in tumorigenesis and drug resistance.

Chromosome instability (CIN) is frequently observed in many tumors. The breakage-fusion-bridge (BFB) cycle has been proposed to be one of the main drivers of CIN during tumorigenesis and tumor evolution. However, the detailed mechanisms for the individual steps of the BFB cycle warrants further investigation.

Background: Lyme disease is a serious infectious disease having a restricted worldwide distribution for which there is no vaccine available for human use.

Objective: This study was designed to determine common reactive antigens involved in Borrelia burgdorferi (Bb) infection that are recognized in mammalian sera that may be useful for vaccine development.

Methods: Blood samples were collected from patients with documented Lyme disease, and from rabbits and mice experimentally infected with either tick-transmitted or culture-grown Borrelia burgdorferi.

Context: Ehlers-Danlos syndromes (EDS) are disorders of connective tissue that lead to a wide range of clinical presentations. While we are beginning to understand the association between EDS and psychological manifestations, it is critical that we further elucidate the relationship between the two. Understanding the correlation between EDS and mental health will better ensure swift diagnosis and effective treatment for patients.
