Mechanisms of replication and repair in mitochondrial DNA deletion formation

Nucleic Acids Research, 2020
Deletions in mitochondrial DNA (mtDNA) are associated with diverse human pathologies including cancer, aging and mitochondrial disorders. Large-scale deletions span kilobases in length and the loss of these associated genes contributes to crippled ...

Structure–Function Analysis Reveals the Singularity of Plant Mitochondrial DNA Replication Components: A Mosaic and Redundant System

Plants, 2019
Plants are sessile organisms, and their DNA is particularly exposed to damaging agents. The integrity of plant mitochondrial and plastid genomes is necessary for cell survival.

A new method for long-read sequencing of animal mitochondrial genomes: application to the identification of equine mitochondrial DNA variants

BMC Genomics, 2020
Background Mitochondrial DNA is remarkably polymorphic. This is why animal geneticists survey mitochondrial genomes variations for fundamental and applied purposes.

Cytoplasmic DNA in the unfertilized sea urchin egg: Physical properties of circular mitochondrial DNA and the occurrence of catenated forms [PDF]

, 1968
The mitochondrial DNA in the unfertilized egg of the sea urchin Lytechinus pictus is present in an amount approximately seven times that of the haploid nuclear DNA.(1) The mitochondrial DNA has a higher buoyant density than the nuclear DNA and consists ...

Mitochondrial Dna Replacement Versus Nuclear Dna Persistence

, 2006
In this paper we consider two populations whose generations are not overlapping and whose size is large. The number of males and females in both populations is constant.

Melatonin inhibits cytosolic mitochondrial-DNA induced neuroinflammatory signaling in accelerated aging and neurodegeneration.

Journal of Clinical Investigation, 2020
Chronic inflammation is a pathologic feature of neurodegeneration and aging; however, the mechanism regulating this process is not understood. Melatonin, an endogenous free radical scavenger synthesized by neuronal mitochondria, decreases with aging and ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
