Ultrafine anaphase bridges

Web26 Apr 2012 · Centromeric ultrafine anaphase bridges are physiological DNA structures thought to contain unresolved DNA catenations between the centromeres separating during anaphase. BLM and PICH helicases colocalize at these ultrafine anaphase bridges and promote their resolution. Web1 Jan 2024 · Ultrafine anaphase bridges (UFBs) are thin DNA threads linking the separating sister chromatids in the anaphase of mitosis. UFBs are thought to form when topological …

Web16 Jul 2015 · There are two types of sister-chromatid anaphase bridges: chromatin bridges, consequences of defective sister chromatid segregation , can be stained with conventional dyes, such as DAPI; and ultrafine anaphase bridges (UFBs), which cannot be stained with conventional DNA dyes or antibodies against histones [8, 9]. UFBs were discovered only … WebEventually, in mitosis, they can evolve into ultrafine anaphase bridges (UFBs) connecting sister chromatids, which can finally lead to chromosomal instability. In the following sections, we focus on CFSs as an example of the extraordinary processes that cells carry out in mitosis to resolve problems that originated during the previous S-phase, in order to … introduction to optimum design 1989 https://creativebroadcastprogramming.com

Web16 May 2011 · Intriguingly replication fork stalling and DNA breakage correlate with the appearance of structures that are analogous to ultrafine anaphase bridges (UFBs), which frequently form at fragile sites during mitosis in human cells, and are thought to occur when replication is incomplete (18,19). We propose that a failure of replication restart at non … WebRif1 thus acts as a double-edged sword. Although it inhibits the resolution of taz1Δ telomere entanglements, it promotes the resolution of non-telomeric ultrafine anaphase bridges at ≤20°C. We suggest a unifying model for Rif1’s seemingly diverse roles in chromosome segregation in eukaryotes.

Web12 Mar 2015 · Thus far TOPBP1 localisation to ultra-fine anaphase bridges (UFBs) has been reported only in yeast Saccharomyces cerevisiae and the transformed avian B-lymphoblastoid cell line DT40 16. Therefore, we decided to test if this was also the case in human transformed and importantly, primary cells. Web1 Jun 2024 · Although chromatin bridges and lagging chromatin are always pathological (generating aneuploidy or complex genomic rearrangements), the main subject of this article, the ultrafine anaphase bridges, might, in addition to potentially driving genomic instability, play critical roles for the maintenance of chromosome structure in rapidly ...
