Diploid-specific genome stability genes of S. cerevisiae: genomic screen reveals haploidization as an escape from persisting DNA rearrangement stress. [PDF]

open access: yes, 2011
Maintaining a stable genome is one of the most important tasks of every living cell and the mechanisms ensuring it are similar in all of them. The events leading to changes in DNA sequence (mutations) in diploid cells occur one to two orders of magnitude

A Chemical Screen Identifies Compounds Capable of Selecting for Haploidy in Mammalian Cells

open access: yesCell Reports, 2019
Summary: The recent availability of somatic haploid cell lines has provided a unique tool for genetic studies in mammals. However, the percentage of haploid cells rapidly decreases in these cell lines, which we recently showed is due to their overgrowth ...

Clinical consequences of BRCA2 hypomorphism

open access: yesnpj Breast Cancer, 2021
The tumor suppressor FANCD1/BRCA2 is crucial for DNA homologous recombination repair (HRR). BRCA2 biallelic pathogenic variants result in a severe form of Fanconi anemia (FA) syndrome, whereas monoallelic pathogenic variants cause mainly hereditary ...

Mutation-Derived Long Noncoding RNA Signature Predicts Survival in Lung Adenocarcinoma

open access: yesFrontiers in Oncology, 2022
BackgroundGenomic instability is one of the representative features of cancer evolution. Recent research has revealed that long noncoding RNAs (lncRNAs) play a critical role in maintaining genomic instability. Our work proposed a gene signature (GILncSig)

Genomic instability is associated with natural life span variation in Saccharomyces cerevisiae. [PDF]

open access: yesPLoS ONE, 2008
Increasing genomic instability is associated with aging in eukaryotes, but the connection between genomic instability and natural variation in life span is unknown. We have quantified chronological life span and loss-of-heterozygosity (LOH) in 11 natural

Colorectal cancers with microsatellite instability display mRNA expression signatures characteristic of increased immunogenicity [PDF]

open access: yes, 2004
Background Colorectal cancers displaying high-degree microsatellite instability (MSI-H) have an improved prognosis compared to microsatellite stable (MSS) cancers.

Disruption of the β-catenin destruction complex via Ephexin1-Axin1 interaction promotes colorectal cancer proliferation

open access: yesExperimental and Molecular Medicine
Wnt signaling is essential for cell growth and tumor formation and is abnormally activated in colorectal cancer (CRC), contributing to tumor progression; however, the specific role and regulatory mechanisms involved in tumor development remain unclear ...

Critical roles of Dpb3-Dpb4 sub-complex of DNA polymerase epsilon in DNA replication, genome stability, and pathogenesis of Candida albicans

open access: yesmBio
DNA polymerase ε (Polε) is an essential replicative polymerase consisting of Pol2, Dpb2, Dpb3, and Dpb4 subunits and has not been explored in the pathogenic yeast Candida albicans. C. albicans is accountable for >40% of deaths due to systemic candidiasis

Tumor Hypoxia Drives Genomic Instability

open access: yesFrontiers in Cell and Developmental Biology, 2021
Cancer is a leading cause of death worldwide. As a common characteristic of cancer, hypoxia is associated with poor prognosis due to enhanced tumor malignancy and therapeutic resistance.

A Proteomic Characterization of Factors Enriched at Nascent DNA Molecules

open access: yesCell Reports, 2013
DNA replication is facilitated by multiple factors that concentrate in the vicinity of replication forks. Here, we developed an approach that combines the isolation of proteins on nascent DNA chains with mass spectrometry (iPOND-MS), allowing a ...
