35 Years of TFAM Research: Old Protein, New Puzzles

Biology, 2023
Transcription Factor A Mitochondrial (TFAM), through its contributions to mtDNA maintenance and expression, is essential for cellular bioenergetics and, therefore, for the very survival of cells.

Mitochondrial DNA Methylation and Human Diseases

International Journal of Molecular Sciences, 2021
Epigenetic modifications of the nuclear genome, including DNA methylation, histone modifications and non-coding RNA post-transcriptional regulation, are increasingly being involved in the pathogenesis of several human diseases.

Structural and Molecular Basis for Mitochondrial DNA Replication and Transcription in Health and Antiviral Drug Toxicity

Molecules, 2023
Human mitochondrial DNA (mtDNA) is a 16.9 kbp double-stranded, circular DNA, encoding subunits of the oxidative phosphorylation electron transfer chain and essential RNAs for mitochondrial protein translation.

Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability [PDF]

, 2018
R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent R loops may become pathological

Genome-wide characterization of mitochondrial DNA methylation in human brain

Frontiers in Endocrinology, 2023
BackgroundThere is growing interest in the role of DNA methylation in regulating the transcription of mitochondrial genes, particularly in brain disorders characterized by mitochondrial dysfunction.

Plant mitochondrial DNA

Frontiers in Bioscience, 2017
Plants possess mitochondrial genomes that are large and complex compared to animals. Nearly all animal mitochondrial genomes are about 16.5. kbp in length, whereas plant mitochondrial genomes range between 200-2,000 kbp. This is curious if we assume modern mitochondria originated from a common alpha-proteobacterial ancestor.

Mutant mitochondrial elongation factor G1 and combined oxidative phosphorylation deficiency [PDF]

, 2004
Although most components of the mitochondrial translation apparatus are encoded by nuclear genes, all known molecular defects associated with impaired mitochondrial translation are due to mutations in mitochondrial DNA.

Common Mitochondrial DNA Mutations Generated through DNA-Mediated Charge Transport [PDF]

, 2009
Mutation sites that arise in human mitochondrial DNA as a result of oxidation by a rhodium photooxidant have been identified. HeLa cells were incubated with [Rh(phi)2bpy]Cl3 (phi is 9,10-phenanthrenequinone diimine), an intercalating photooxidant, to ...

Regional differences in mitochondrial DNA methylation in human post-mortem brain tissue

Clinical Epigenetics, 2017
Background DNA methylation is an important epigenetic mechanism involved in gene regulation, with alterations in DNA methylation in the nuclear genome being linked to numerous complex diseases.
