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) ...

MetabolomicsPRODH regultes naive pluripotency by influencing mitochondrial oxidative phosphorylation (Targeted metabolomics)

Naïve human embryonic stem cells (hESCs) that resemble the pre-implantation epiblasts are fueled by a combination of aerobic glycolysis and oxidative phosphorylation, but their mitochondrial regulators are poorly understood. Here we report that, proline dehydrogenase (PRODH), a mitochondria-local...

MetabolomicsPRODH regultes naive pluripotency by influencing mitochondrial oxidative phosphorylation (Untargeted metabolomics)

Naïve human embryonic stem cells (hESCs) that resemble the pre-implantation epiblasts are fueled by a combination of aerobic glycolysis and oxidative phosphorylation, but their mitochondrial regulators are poorly understood. Here we report that, proline dehydrogenase (PRODH), a mitochondria-local...

GenomicsMapping mitochondrial DNA recombination in yeast
In this study, we present the first genome-wide recombination map for mitochondrial DNA in yeast. We also assess the impact of the genetic background and of several gene deletions on the recombination profiles.

TranscriptomicsInsights into N-calls of mitochondrial DNA sequencing using MitoChip v2.0
Background: Developments in DNA resequencing microarrays include mitochondrial DNA (mtDNA) sequencing and mutation detection. During automated analysis to sequence mtDNA, bases can be identified as wildtype, variant, or there may be a failure to assign a base (N-call) when compared to the mtDNA refe...

MetabolomicsMitochondrial metabolism sustains DNMT3A-R882-mutant clonal haematopoiesis
Somatic DNMT3A R882 codon mutations drive the most common form of clonal haematopoiesis (CH) and are associated with increased acute myeloid leukaemia (AML) risk1,2. Preventing expansion of DNMT3A-R882-mutant haematopoietic stem/progenitor cells (HSPCs) may therefore avert progression to AML. To ide...

MetabolomicsMitochondrial respiration in B lymphocytes is essential for humoral immunity by controlling flux of the TCA cycle

To elucidate the function of oxidative phosphorylation (OxPhos) during B-cell differentiation we employ CD23Cre-driven expression of the dominant-negative K320E mutant of the mitochondrial helicase Twinkle (DNT). DNT-expression depletes mitochondrial DNA during B cell maturation, reduces the abun...

TranscriptomicsBiased transcription and selective degradation of small RNAs shape the pattern of DNA elimination in Tetrahymena
The ciliated protozoan Tetrahymena undergoes extensive programmed DNA elimination when the germline micronucleus produces the new macronucleus during sexual reproduction. DNA elimination is epigenetically controlled by DNA sequences of the parental macronuclear genome, and this epigenetic regulation...

GenomicsDNA-seq of mitochondrial DNA from mouse heart that is both heart SOD2 knockout and deficient for mitochondrial DNA repair
To study whether increase in mitochondrial oxidative stress (SOD2 removal) and decrease in mitochondrial DNA repair (Ogg1 dMTS) results into increase in mitochondrial DNA mutation load. Oxidative stress has been suggested to induce mutations in mtDNA. To verify this, we extracted and sequenced (Illu...

TranscriptomicsAntisense Transcripts Impede Uridylation-induced Exonucleolytic Degradation to Generate Guide RNAs
Small non-coding RNA biogenesis typically involves cleavage of structured precursors by RNase III-like endonucleases. However, guide RNAs that direct U-insertion/deletion mRNA editing in mitochondria of trypanosomes maintain 5′ triphosphate characteristic of transcription start site and possess U-...
