Ivessa A, Singh S
Sci Rep
. 2023 Oct;
13(1):17832.
PMID: 37857740
Calorie restriction (CR), which is a reduction in calorie intake without malnutrition, usually extends lifespan and improves tissue integrity. This report focuses on the relationship between nuclear genomic instability and...

Trends Cancer
. 2017 Jul;
3(6):387-390.
PMID: 28718415
Many cancers are initiated by loss-of-heterozygosity (LOH) events that lead to the replacement of single, functional tumor suppressor genes by the mutant alleles. The underlying mechanisms, of why LOH rates...

Cabral M, Cheng X, Singh S, Ivessa A
Cell Rep
. 2016 Nov;
17(7):1747-1754.
PMID: 27829146
There is substantial evidence that genomic instability increases during aging. Replication pausing (and stalling) at difficult-to-replicate chromosomal sites may induce genomic instability. Interestingly, in aging yeast cells, we observed reduced...

Schneider J, Cheng X, Zhao Q, Underbayev C, Gonzalez J, Raveche E, et al.
Stem Cells Dev
. 2014 Jun;
23(22):2712-9.
PMID: 24964274
According to the endosymbiotic hypothesis, the precursor of mitochondria invaded the precursor of eukaryotic cells, a process that began roughly 2 billion years ago. Since then, the majority of the...

Methods Mol Biol
. 2013 Aug;
1054:83-103.
PMID: 23913286
The analysis of replication intermediates by the neutral-neutral two-dimensional agarose gel technique allows determining the chromosomal positions where DNA replication initiates, whether replication forks pause or stall at specific sites,...

Methods Mol Biol
. 2013 Aug;
1054:63-81.
PMID: 23913285
The neutral-neutral two-dimensional agarose gel technique is mainly used to determine the chromosomal positions where DNA replication starts, but it is also applied to visualize replication fork progression and breakage...

Eur J Cell Biol
. 2012 Aug;
91(10):782-8.
PMID: 22857949
Translocation of mitochondrial DNA (mtDNA) fragments to the nucleus and insertion of those fragments into nuclear DNA has been observed in several organisms ranging from yeast to plants and mammals....

Eur J Cell Biol
. 2010 Jul;
89(10):742-7.
PMID: 20655619
Previously we demonstrated that the mitochondrial form of the yeast Pif1p DNA helicase, which we found to be attached to mitochondrial DNA (mtDNA), is required for the maintenance of mtDNA...

Cheng X, Ivessa A
Aging Cell
. 2010 Jul;
9(5):919-23.
PMID: 20626726
Migration of fragmented mitochondrial DNA (mtDNA) to the nucleus has been shown to occur in multiple species including yeast, plants, and mammals. Several human diseases, including Pallister-Hall syndrome and mucolipidosis,...

Mol Genet Genomics
. 2009 Mar;
281(6):635-45.
PMID: 19277716
How the cellular amount of mitochondrial DNA (mtDNA) is regulated under normal conditions and in the presence of genotoxic stress is less understood. We demonstrate that the inefficient mtDNA replication...
