DNA replication stress triggers rapid DNA replication fork breakage by Artemis and XPF. [PDF]
PLoS Genetics, 2018 DNA replication stress (DRS) leads to the accumulation of stalled DNA replication forks leaving a fraction of genomic loci incompletely replicated, a source of chromosomal rearrangements during their partition in mitosis.

Tetraploidy causes chromosomal instability in acentriolar mouse embryos
Nature Communications, 2019 During cell division, tetraploidy can drive chromosomal instability (CIN) via supernumerary centrosomes, but it is unclear if this is the only route to CIN. Here the authors show that, in early mouse embryos, tetraploidy can drive chromosomal instability

A role for polyploidy in the tumorigenicity of Pim-1-expressing human prostate and mammary epithelial cells. [PDF]
PLoS ONE, 2008 BackgroundPolyploidy is a prominent feature of many human cancers, and it has long been hypothesized that polyploidy may contribute to tumorigenesis by promoting genomic instability.

Regrowth resistance: low-level platinum resistance mediated by rapid recovery from platinum-induced cell-cycle arrest [PDF]
, 2009 The H69CIS200 and H69OX400 cell lines are novel models of low-level platinum drug resistance developed from H69 human small cell lung cancer cells with eight 4-day treatments of 200 ng/ml cisplatin or 400 ng/ml oxaliplatin respectively. A recovery period

Nucleosome footprinting in plasma cell-free DNA for the pre-surgical diagnosis of ovarian cancer
npj Genomic Medicine, 2022 Fragmentation patterns of plasma cell-free DNA (cfDNA) are known to reflect nucleosome positions of cell types contributing to cfDNA. Based on cfDNA fragmentation patterns, the deviation in nucleosome footprints was quantified between diagnosed ovarian ...

Drug Targeting of Genomic Instability in Multiple Myeloma
Frontiers in Genetics, 2020 Genomic instability can be observed at both chromosomal and chromatin levels. Instability at the macro level includes centrosome abnormalities (CA) resulting in numerical as well as structural chromosomal changes, whereas instability at the micro level ...

hints to chromosomal instability after irradiation [PDF]
, 2016 Background Total body irradiation (TBI) has been part of standard conditioning regimens before allogeneic stem cell transplantation for many years. Its effect on normal tissue in these patients has not been studied extensively.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
