MetabolomicsTFAM loss induces nuclear actin assembly upon mDia2 malonylation to promote liver cancer metastasis
The mechanisms underlying cancer metastasis remain poorly understood. Here, we report that TFAM deficiency rapidly and stably induced spontaneous lung metastasis in mice with liver cancer. Interestingly, unexpected polymerization of nuclear actin was observed in TFAM-knockdown HCC cells when cytoske...

Metabolomics1H NMR metabolomic and transcriptomic analyses reveal urinary metabolites as biomarker candidates in response to protein undernutrition in adult rats

BACKGROUND: Protein undernutrition is prevalent mainly among elderly people, and it could develop diseases such as sarcopenia. Urinary metabolites may become biomarkers reflecting protein undernutrition, but this has been insufficiently investigated.

OBJECTIVE:

MetabolomicsInositol Pyrophosphates Mediate Chloroplast Lipid Remodeling and Nuclear Gene Repression during High-Light Acclimation in Chlamydomonas reinhardtii
Microalgae are photosynthetic organisms capable of autotrophic growth. Their applicability in multiple industrial fields has been largely studied, thanks to their ability to fixate CO2 into high added value organic products like fatty acids and carotenoids. However, our under-standing of the cellula...

MetabolomicsThe Bardet-Biedl protein Bbs1 controls photoreceptor outer segment protein and lipid composition

Summary

Primary cilia are key sensory organelles whose dysfunction leads to ciliopathy disorders such as Bardet-Biedl syndrome (BBS). Retinal degeneration is common in ciliopathies, since the outer segments (OSs) of photoreceptors are highly specialized primary cilia. BBS...

MetabolomicsA multi-omics dataset of heat-shock response in the yeast RNA binding protein Mip6 (NMR assay)

Gene expression is a biological process regulated at different molecular levels, including chromatin accessibility, transcription, and RNA maturation and transport. In addition, these regulatory mechanisms have strong links with cellular metabolism. Here we present a multi-omics dataset that capt...

TranscriptomicsRNA-seq reveals that Air1 and Air2 control TRAMP substrate specificity for nuclear RNA surveillance
The Saccharomyces cerevisiae TRAMP4 and TRAMP5 complexes, which consist of the poly(A) polymerase Trf4 or Trf5, respectively, the zinc knuckle proteins Air1 or Air2, and the RNA helicase Mtr4, play a critical role in nuclear RNA surveillance. Although it is known to enhance the nuclease activity of ...

MetabolomicsIntegration of magnetic resonance imaging and protein and metabolite CSF measurements to enable early diagnosis of secondary progressive multiple sclerosis

Molecular networks in neurological diseases are complex. Despite this fact, contemporary biomarkers are in most cases interpreted in isolation, leading to a significant loss of information and power. We present an analytical approach to scrutinize and combine information from biomarkers originati...

MetabolomicsSexual Propagation Enhances Tea Quality Through Rhizosphere Microbiome Assembly and Metabolic Reprogramming in Camellia sinensis
Tea quality is primarily determined by the accumulation of specialized metabolites in fresh leaves; however, the mechanisms by which propagation methods influence tea qual-ity through plant–soil–microbiome interactions remain poorly understood. Here, sexually propagated (SR) and asexually propagated...

TranscriptomicsQuality control of transcription start site selection by Nonsense-Mediated-mRNA Decay
Nonsense-mediated mRNA decay (NMD) is a translation-dependent RNA quality-control pathway targeting transcripts such as messenger RNAs harboring premature stop-codons or short upstream open reading frame (uORFs). Our transcription start sites (TSSs) analysis of Saccharomyces cerevisiae cells deficie...

TranscriptomicsThe insulator protein SU(HW) modulates nuclear lamina interactions of the Drosophila genome: DamID
Specific interactions of the genome with the nuclear lamina (NL) are thought to assist chromosome folding inside the nucleus and to contribute to the regulation of gene expression. High-resolution mapping has recently identified hundreds of large, sharply defined lamina-associated domains (LADs) in ...
