MetabolomicsBenchmark datasets for 3D MALDI- and DESI-Imaging Mass Spectrometry
Three-dimensional imaging mass spectrometry (3D imaging MS) is a technique of analytical chemistry for 3D molecular analysis of a tissue specimen, entire organ, or microbial colonies on an agar plate. 3D imaging MS has unique advantages over existing 3D imaging techniques, offers novel perspectives ...

TranscriptomicsPost-transcriptional fine-tuning of COP9 signalosome subunit biosynthesis is regulated by the c-Myc/Lin28B/let-7 pathway
The COP9 signalosome (CSN) is a conserved protein complex occurring in all eukaryotes. The mammalian CSN consists of eight subunits (CSN1 – CSN8) and possesses an intrinsic metalloprotease JAMM motif localised to CSN5. In addition, it is associated with kinases such as protein kinase CK2 and D and t...

TranscriptomicsThe conserved ubiquitin-like protein Hub1 plays a critical role in splicing in human cells
Different from canonical ubiquitin-like proteins, Hub1 does not form covalent conjugates with substrates but binds proteins non-covalently. In Saccharomyces cerevisiae, Hub1 associates with spliceosomes and mediates alternative splicing of SRC1, without affecting pre-mRNA splicing generally. Human H...

TranscriptomicsThe tumor antigen PRAME is a substrate recognition subunit of a Cul2-based ubiquitin ligase and is associated with active NFY promoters
The human tumor antigen PRAME (Preferentially expressed antigen of melanoma) is frequently overexpressed in tumors. High PRAME levels correlate with poor clinical outcome of several cancers, but the mechanisms by which PRAME could be involved in tumorigenesis remain largely elusive. We applied prote...

TranscriptomicsTumor cell-specific inhibition of MYC function using small molecule inhibitors of the HUWE1 ubiquitin ligase
Deregulated expression of MYC is a driver of colorectal carcinogenesis, necessitating novel strategies to inhibit MYC function. The ubiquitin ligase HUWE1 (HECTH9, ARFBP1, MULE) associates with both MYC and the MYC-associated protein MIZ1. We show here that HUWE1 is required for growth of colorecta...

ProteomicsEndo-Lysosomal Proteins and Ubiquitin CSF Concentrations in Alzheimer’s and Parkinson’s Disease
Alzheimer’s (AD) and Parkinson’s disease (PD) are neurodegenerative disorders characterized by an accumulation of protein aggregates in the brain. AD is the most common cause of dementia and presents with impairment of memory and cognition. PD results from the loss of dopaminergic neurons which resu...

ProteomicsCRL4(CRBN) ubiquitin ligase profiling
In the 1950s the drug thalidomide administered as a sedative to pregnant women led ot the birth of thousands of children with multiple defects. Despite its teratogenicity, thalidomide and ist IMiD derivatives recently emerged as effective treatments for multiple myeloma and 5q-dysplasia. IMiDs targe...

ProteomicsRegulation of the Endocytosis and Prion Chaperoning Machineries by Yeast E3 Ubiquitin Ligase Rsp5 as Revealed by Orthogonal Ubiquitin Transfer
Attachment of the ubiquitin (UB) peptide to proteins via the E1-E2-E3 enzymatic machinery regulates diverse biological pathways, yet identification of the substrates of E3 UB ligases remains a challenge. We overcame this challenge by constructing an “orthogonal UB transfer (OUT) cascade with yeast E...

ProteomicsUbiquitination at the Parkin ubiquitin-like domain suggests a new mechanism for Parkin activation
The mitochondrial kinase PINK1 and the cytosolic ubiquitin ligase (E3) Parkin is involved in mitochondrial quality control. PINK1, which phosphorylates ubiquitin at serine 65 residue and the ubiquitin-like (Ubl) domain of Parkin at serine 65 residue, promotes the Parkin activation and translocation ...

MetabolomicsHarnessing Exogenous Stimuli and Functionally 3D Aligned Fibrous Scaffolds for Spatiotemporal Modulation of Bone Regeneration

Bone regeneration requires spatiotemporal coordination of immune modulation, stem cell recruitment, angiogenesis, and osteogenesis, yet most scaffolds lack sequential control across healing phases. We develop a near-infrared (NIR)-responsive therapeutic platform that integrates clinically av...
