Reanalysis of the human testis tissue dataset acquired for the Chromosome-centric Human Proteome Project (C-HPP; PRIDE project PXD002179), with a focus on identifying novel peptides for genome annotation.
Assessing the impact of genomic alterations on protein networks is fundamental in identifying the mechanisms that shape cancer heterogeneity. We have used isobaric labelling to characterize the proteomic landscapes of 50 colorectal cancer cell lines and to decipher the functional consequences of som...
Shigella flexneri 2a and Shigella sonnei were genetically modified to shed large quantities of outer membrane blebs. The blebs, called Generalized Modules for Membrane Antigens (GMMA), were purified and the protein content was estimated using the label-free iBAQ procedure. There were 2308 proteins i...

Covalent modifications of proteins with ubiquitin and ubiquitin-like molecules are instrumental to most, if not all biological processes. However, identifying the E3 ligase responsible for these modifications remains a major bottleneck in ubiquitin research. Here, we have developed an E2-thioester-d...

Many enteric pathogens employ a type III secretion system (T3SS) to translocate effector proteins directly into the host cell cytoplasm, where they subvert signaling pathways of the intestinal epithelium. Here, we report that the anti-apoptotic regulator HS1-associated protein X1 (HAX-1) is an inter...

Induced pluripotent stem (iPS) cell derived human macrophages were stimulated with IFN-y or exposed to viable S. Typhimurium SL1344 using either a gentamicin invasion assay or after over-night priming with IFN-y. Protein abundance changes between samples was determined relative to unstimulated contr...
Large scale proteomic profiling of cell lines can yield valuable insights into the molecular signatures attributed to variable genotypes or induced perturbations. Specifically, the ability to perform deep and rapid proteome analysis of pharmacologically modulated cells could generate drug-protein as...

The FBXW7 tumour suppressor is commonly mutated, deleted or hypermethylated in a variety of cancer histologies. The tumour suppressive role of the FBXW7 protein has been ascribed to its ability to drive the ubiquitination and degradation of oncoproteins via its role as a substrate recognition subuni...
Cancer associated fibroblasts (CAFs) are a key component of tumors. We aimed to profile the proteome of cancer cell lines representing three common cancer types (lung, colorectal and pancreatic) and a representative CAF cell line from each tumor type to gain insight into CAF function and identify ne...
