Mitochondrial RNA granules: Compartmentalizing mitochondrial gene expression

In mitochondria, DNA replication, gene expression, and RNA degradation machineries coexist within a common nondelimited space, raising the question of how functional compartmentalization of gene expression is achieved. Here, we discuss the recently characterized "mitochondrial RNA granules," mitochondrial subdomains with an emerging role in the regulation of gene expression.

Mitochondrial transcription termination factor 2 binds to entire mitochondrial DNA and negatively regulates mitochondrial gene expression.

Mitochondrial transcription termination factor 2 (mTERF2) is a mitochondrial matrix protein that binds to the mitochondrial DNA. Previous studies have shown that overexpression of mTERF2 can inhibit cell proliferation, but the mechanism has not been well defined so far. This study aimed to present the binding pattern of mTERF2 to the mitochondrial DNA (mtDNA) in vivo, and investigated the biolo...

Inhibition of microRNA-182 reduces hypoxia/re-oxygenation-induced HL-1 cardiomyocyte apoptosis by targeting the nuclear respiratory factor-1/mitochondrial transcription factor A (NRF-1/mtTFA) pathway

Apoptosis is a component of cardiac remodeling following myocardial ischemia and infarction. MicroRNAs (miRNAs) are involved in regulating a range of cellular biological processes, including apoptosis, by regulating gene expression at the post-transcriptional level. Nuclear respiratory factor-1 (NRF-1) is a transcriptional activator of nuclear genes that encode a range of mitochondrial proteins...

Overexpression of Mitochondrial Genes (Mitochondrial Transcription Factor A and Cytochrome c Oxidase Subunit 1) in Mouse Metaphase II Oocytes following Vitrification via Cryotop

Background: Gamete cryopreservation is an inseparable part of assisted reproductive technology, and vitrification is an effective approach to the cryopreservation of oocytes. The aim of this study was to investigate vitrification effects on the expression levels of mitochondrial transcription factor A (Tfam) and mitochondrial-encoded cytochrome c oxidase subunit 1 (Cox1) in mouse metaphase II o...
