TranscriptomicsSIRT7-dependent deacetylation of the U3-55k protein controls pre-rRNA processing [CLIP-Seq]
SIRT7 is an NAD+-dependent protein deacetylase with important roles in ribosome biogenesis and cell proliferation. Previous studies have established that SIRT7 is associated with RNA polymerase I, interacts with pre-rRNA and promotes rRNA synthesis. Here we show that SIRT7 is also associated with sn...

TranscriptomicsExpression of sense and antisense transcripts at the ribosomal locus
Epigenetic methyl-CpG silencing of the ribosomal RNA (rRNA) genes is thought to down-regulate rRNA synthesis in mammals. In contrast, we now show that CpG methylation in fact positively influences rRNA synthesis and processing. Human HCT116 cells, inactivated for DNMT1 and DNMT3b or treated with aza...

MetabolomicsHost: Microbiome co-metabolic processing of dietary polyphenols – An acute, single blinded, cross-over study with different doses of apple polyphenols in healthy subjects
Apples are one of the most commonly consumed fruits and their high polyphenol content is considered one of the most important determinants of their health-promoting activities. Here we studied the nutrikinetics of apple polyphenols by UHPLC-HRMS metabolite fingerprinting, comparing the bioavailabili...

ProteomicsA trypanosome-specific complex mediates late-stage processing of cytosolic LSU rRNA
Unlike most eukaryotes, Trypanosoma brucei processes its cytosolic large subunit (LSU) RNA into six fragments. The factors responsible for these processing events were previously unknown. Here, we identify TbLrRP1 and TbLrRP2 as essential components of this trypanosome-specific LSU RNA processing pa...

ProteomicsThe Ubiquitin-Specific Protease USP36 SUMOylates EXOSC10 and promotes the nucleolar RNA exosome function in rRNA processing
The RNA exosome is an essential 3’ to 5’ processing exoribonuclease complex that mediates degradation, processing, and quality control of virtually all eukaryotic RNAs. The nucleolar RNA exosome, consisting of a 9-subunit core and a distributive 3ʹ to 5ʹ exonuclease EXOSC10, plays a critical role in...

ProteomicsFGF2 antiproliferative stimulus triggers proteomic and transcriptional changes associated with nucleolar disorganization in K-ras-driven mouse tumor cells (Nucleoli TMT)
Chromatin plays a crucial role in the intermediation between cell signaling and gene expression. The nucleolus is sensitive to stress and can orchestrate a chain of cellular events in response to stress signals. Despite being a growth factor, FGF2 has anti-proliferative and tumor-suppressive functio...

ProteomicsBMAL1 associates with NOP58 in the nucleolus and contributes to pre-rRNA processing
The transcription factor BMAL1 is a core element of the circadian clock that contributes to cyclic control of genes transcribed by RNA polymerase II. By using biochemical cellular fractionation and immunofluorescence analyses we reveal a previously uncharacterized nucleolar localization for BMAL1. W...
