AP-MS analysis of human FUBIeS30/FAU WT and non-cleavable G73,4A and G74V mutants

ABSTRACT: To discover candidate FUBIeS30 proteases, we performed affinity purification from human cell lysates expressing tandem Strep II-hemagglutinin (StHA)-tagged WT or mutant (G73,74A or G74V) FUBIeS30-StHA constructs. Subsequent analysis of the co-purified proteins by mass spectrometry (LC-MS/MS) identified differentially interacting factors. We found that two deubiquitinases, USP10 and USP36, were enriched on the non-cleavable mutants compared to WT and subsequently confirmed that USP36 is involved in FUBIeS30 processing in vivo.

Development of gene expression signatures for neonatal tissues of mice with Usp10 gene knockout

Project description:To further explore gene expression in neonatal mice with Usp10 gene knockout, we have employed whole genome microarray expression profiling as a discovery platform to identify the pathways or biological processes with the potential to explain the cause of postnatal death of Usp10 knockout mice. Kidney tissues from Usp10 knockout neonates and their littermates were used to be the samples to explore.

SPOP promotes transcriptional expression of DNA repair and replication factors to prevent replication stress and genomic instability.

Project description:Mutations in SPOP, the gene most frequently point-mutated in primary prostate cancer, are associated with a high degree of genomic instability and deficiency in homologous recombination repair of DNA but the underlying mechanisms. SPOP knockdown leads to spontaneous replication stress and impaired recovery from replication fork stalling. An SPOP interactome analysis shows that wild type (WT) SPOP but not mutant SPOP associates with multiple proteins involved in transcription, mRNA splicing and export. Consistent with the association of SPOP with transcription, splicing and RNA export complexes, the decreased expression of several components of the DNA damage response pathway occurs at the level of transcription.

Deubiquitinase USP10 regulates Notch signaling in the endothelium

Project description:Notch signaling is critical for vascular morphogenesis by co-determining the sprouting behavior of endothelial cells. Here, we investigate the function of ubiquitin-specific peptidase 10 (USP10) in regulation of the turnover of the NOTCH1 intracellular domain. HUVEC were transfected with scrambled or USP10 targeting siRNA and then stimulated by treatment with DLL4 or control. RNA for analysis was isolated after 24 hours of DLL4 stimulation.

HEK NICD AP-MS - Notch signaling is a core patterning module for vascular morphogenesis, which co-determines the sprouting behaviour of endothelial cells (ECs)

Project description:Notch signaling is a core patterning module for vascular morphogenesis, which co-determines the sprouting behaviour of endothelial cells (ECs). Tight quantitative and temporal control of Notch activity is essential for vascular development, yet the details of Notch regulation in ECs are incompletely understood. We found that ubiquitin-specific peptidase 10 (USP10) interacted with the NOTCH1 intracellular domain (NICD1) to slow the ubiquitin-dependent turnover of this short-lived form of the activated NOTCH1 receptor. Accordingly, inactivation of USP10 reduced NICD1 abundance and stability, and diminished Notch-induced target gene expression in ECs. In mice, loss of endothelial Usp10 increased vessel sprouting and partially restored the patterning defects caused by ectopic expression of NICD1. Thus, USP10 functions as an NICD1 deubiquitinase, which fine-tunes endothelial Notch responses during angiogenic sprouting.

AtMYB60

Project description:Stomatal guard-cells modulate gas exchange between the plant and the atmosphere. Regulation of transcription is emerging as an important mechanism in controlling guard cells activity. The Arabidopsis transcription factor AtMYB60, is specifically expressed in guard cells and controls stomatal movements. Opening of stomatal pores is constitutively reduced in the atmyb60-1 null allele, and water loss during drought is diminished in the mutant compared to wild type. To address the effect of the AtMYB60 disruption on global gene expression, total mRNAs, derived from atmyb60-1 and WT rosette leaves, grown in standard conditions, were hybridized to a cDNA microarray.

Transcription profiling of yeast mutant strains vs WT: YIA29 (mdl1::HIS3); YIA30 (yme1::KAN); YIA31 (mdl1::HIS3 yme1::KAN);

Project description:All yeast strains were in the genetic background W303-1A (MATa leu2-3,112 trp1-1 ura3-1 can1-100 ade2-1 his3-11,15). Gene expression profiles of the following mutant strains were compared with WT: YIA29 (mdl1::HIS3); YIA30 (yme1::KAN); YIA31 (mdl1::HIS3 yme1::KAN); 2 independent RNA preparations per strain were used (A and B); 2 independent array hybridisations per RNA preparation were performed (color switch experiments).

Stabilisation of b-Catenin-WNT signalling by USP10 in APC-truncated colorectal cancer drives cancer stemness and enables super-competitor signalling

Project description:The contribution of deubiquitylating enzymes to b-Catenin stabilisation in intestinal stem cells and colorectal cancer (CRC) is poorly understood. Here, we report the deubiquitylase USP10 as APC-truncation- specific regulator enhancer of b-Catenin stability, potentiating WNT signalling pathway in CRC and cancer stem cells. Mechanistically, interaction studies in various CRC cell lines and in vitro binding studies, together with computational modelling, revealed that USP10 binding to b-Catenin is mediated via its USP10 unstructured N-terminus and requires truncated in the absence of full-length APC. Notably, loss of USP10 in CRISPR engineered intestinal organoids reduces tumorigenic properties of CRC cells and organoids, and blocks the super competitor-properties of APC-mutated intestinal cells, elicits induces the expression of differentiation genes, and opposes the APC-truncated phenotype in an intestinal hyperplasia model of D.melanogaster. Taken together, our findings reveal USP10s role in intestinal tumourigenesis by stabilising b-Catenin, leading to aberrant WNT signalling, enhancing cancer cell stemness and implicate the DUB USP10 as a cancer specific therapeutic vulnerability in Apc truncated CRC.

ATAC-seq of primary mammalian aortic endothelial cells before and after TNFα stimulation

Project description:To identify conserved TNFα-induced changes in chromatin-accessibility in mammals, we performed ATAC-seq in primary vascular endothelial cells (ECs) isolated from the aortas of human (HAEC), mouse (MAEC) and cow (BAEC), before and after TNFα. We overlay our data with multi-species NF-κB binding data and identify multiple modes of NF-κB-chromatin interactions that are conserved during mammalian TNFα response. Our cross-species approach identifies conserved changes in chromatin-accessibility at NF-κB binding sites that are disease-relevant and essential during mammalian acute inflammation.
