MetabolomicsSIN-3 transcriptional coregulator maintains mitochondrial homeostasis and polyamine flux
Mitochondrial function relies on the coordinated transcription of mitochondrial and nuclear genomes to assemble respiratory chain complexes. Across species, the SIN3 coregulator influences mitochondrial functions, but how its loss impacts mitochondrial homeostasis and metabolism in the context of a ...

TranscriptomicsThe human mitochondrial transcriptome
The human mitochondrial genome comprises a distinct genetic system transcribed as precursor polycistronic transcripts that are subsequently cleaved to generate individual mRNAs, tRNAs and rRNAs. Here we provide a comprehensive analysis of the human mitochondrial transcriptome across multiple cell li...

TranscriptomicsLooking for mitochondrial associated RNA
We investigated the peripheral mitochondrial localization of nuclear-encoded mRNAs (MLR) in various conditions in which translation was inhibited or the mRNA binding protein context altered (Delta puf3). We used cell fractionation protocols together with microarray to assess the distribution of mRNA...

MetabolomicsTargeting STK39 ameliorates cardiac remodeling by Improving Mitochondrial function through degradation of IFIT3

Pathological cardiac remodeling in response to sustained pressure overload is a pivotal process in the progression of heart failure (HF), yet the underlying molecular mechanisms remain incompletely understood, limiting therapeutic development. Here, we identify serine/threonine kinase 39 (STK39) ...

TranscriptomicsCharacterization of Drosophila mitochondrial transcripts through high throughput EST data
We used high throughput EST sequences to characterize and generate expression profiles for all transcripts encoded in the mitochondrial genome of D. melanogaster and D. pseudoobscura. Mapping of ESTs confirmed previously predicted transcripts and revealed non-canonical transcript structures. Express...

TranscriptomicsRetrograde signalling during caused by heritable mitochondrial dysfunction is partly mediated by ANAC017 and improves plant performance.
Mitochondria are crucial for plant viability and are able to communicate information on their functional status to the cellular nucleus via retrograde signalling, thereby affecting gene expression. It is currently unclear if retrograde signalling in response to constitutive mitochondrial biogenesis ...

TranscriptomicsHeLa cell mitochondrial microRNAs
MicroRNAs (miRNAs) are small non-coding RNAs that associate with Argonaute 2 protein to regulate gene expression at the post-transcriptional level in the cytoplasm. However, recent studies have reported that some miRNAs localize to and function in other cellular compartments. Mitochondria harbour th...

TranscriptomicsDSIF and RNA polymerase II CTD Phosphorylation Coordinate the Recruitment of Rpd3S to Actively Transcribed Genes
Histone deacetylase Rpd3 is part of two distinct complexes: the large (Rpd3L) and small (Rpd3S) complexes. While Rpd3L targets specific promoters for gene repression, Rpd3S is recruited to ORFs to deacetylate histones in the wake of RNA polymerase II, to prevent cryptic initiation within genes. Meth...

TranscriptomicsATFS-1 mediates a protective transcription program during mitochondrial stress
ATFS-1 has been shown to regulate transcription of mitochondrial chaperone genes such as mtHsp70/hsp-6 and hsp-60 in response to mitocondrial stress. To identify the entire ATFS-1-mediated response, we compared the transcript profiles from wild-type and atfs-1(tm4525) worms raised in the absence and...
