MetabolomicsFate and PPARγ and STATs-driven effects of the mitochondrial complex I inhibitor tebufenpyrad in liver cells revealed with multi-omics.
The biological effects of the pesticide and mitochondrial complex I inhibitor tebufenpyrad (TEBU) on liver cells were investigated by combining proteomics and metabolomics. Both cell culture media and cellular lysates were analyzed in dose-response and kinetic experiments on the HepaRG cell line. Re...

MetabolomicsSmall auxin-up RNA promotes GmMYB176 gene transcription to modulate soybean isoflavone content

Isoflavones have been widely studied because of their potential health benefits, including antioxidant, anti-inflammatory, and anticancer properties. Soybeans (Glycine max (L.) Merr) are an effective source of natural isoflavones in humans. Therefore, it is important to cultivate varieties showin...

ProteomicsProteins co-localized with RNA Pol2 in ALS patient-derived neural precursors
Deficiency of proteostasis and RNA metabolism are increasingly recognized as critical drivers of neurodegenerative diseases. In this study, we focused on RNA polymerase II (Pol2) as the converging point of these two elements to understand how transcriptional machinery is affected by ALS-associated V...

GenomicsIdentification of the primary target of the chemotherapeutic agent CX-5461 as a late step in transcription initiation by RNA Polymerase I
In recent years, several small molecule cytotoxic drugs have been identified as potential inhibitors of ribosome biogenesis (Drygin et al., 2011; Peltonen et al., 2014a; Peltonen et al., 2014b). CX-5461 is one such drug that has also demonstrated anticancer potential for a wide range of malignancies...

ProteomicsRNA polymerase III interactome
Many regulatory proteins and complexes have been identified which influence transcription by RNA polymerase (pol) II with a fine precision. In comparison, only a few regulatory proteins are known for pol III, which transcribes mostly house-keeping and non-coding RNAs. Yet, pol III transcription is p...

GenomicsCooperative binding of DNA sequence non-specific HMGbox Factor Ubf and TBP-TAF complex SL1 determines RNA Polymerase I promoter recognition in vivo and its dysfunction underlies the Ubf-E210K neuroregression syndrome
Transcription of the >200 rRNA genes (rDNA) by RNA Polymerase I (RPI) determines as much as 35% of total nuclear RNA synthesis and is a major determinant of cell growth implicated in a range of hypertrophic and developmental disorders. Activation of the rDNA involves the formation of an extended nuc...

TranscriptomicsGenome-wide control of RNA polymerase II activity by cohesin (sequencing)
Cohesin is a well-known mediator of sister chromatid cohesion, but it also influences gene expression and development. These non-canonical roles of cohesin are not well understood, but are vital: gene expression and development are altered by modest changes in cohesin function that do not disrupt ch...

ProteomicsKINETIC AND COMPOSITIONAL ANALYSIS OF RNA POLYMERASE II IN TRYPANOSOMA BRUCEI
Genome-wide analysis of nascent RNA synthesis gives kinetic information on the transcriptional status of RNA polymerase II (Pol II). In parallel, immunoprecipitation of the largest subunit of Pol II (RPB1) provides the protein composition of the enzyme complex in the presence or absence of the tran...

GenomicsRNA polymerase II pausing downstream of core histone genes is different from genes producing polyadenylated transcripts
Recent genome-wide chromatin immunoprecipitation coupled high throughput sequencing (ChIP-seq) analyses performed in various eukaryotic organisms, analysed RNA Polymerase II (Pol II) pausing around the transcription start sites of genes. In this study we have further investigated genome-wide binding...
