In inflammatory arthritis peptidyl arginine deiminase (PAD) enzymes can citrullinate arginine residues in extracellular matrix (ECM) proteins, such as collagens and fibronectin. This may lead to the generation of anti-citrullinated protein antibodies, important diagnostic markers in rheumatoid arthritis. In addition, the citrullination may directly affect protein function. Based on structural analysis, we found that most ECM-associated growth factors (GFs) have arginine residues in their recepto ...[more]

Spatial variation in transcript and protein abundance of Atlantic salmon during feeding migration in the Baltic Sea

Project description:The fitness and reproductive output of fishes can be affected by environmental disturbances. In this study, transcriptomics and label-free proteomics were combined to investigate Atlantic salmon (Salmo salar) sampled from three different field locations within the Baltic Sea (Baltic Main Basin (BMB), Gulf of Finland (GoF) and Bothnian Sea (BS)) during marine migration. The expression of several stress related mRNAs and proteins of xenobiotic metabolism, oxidative stress, DNA damage and cell death were increased in salmon from GoF compared to salmon from BMB or BS. Respiratory electron chain and ATP synthesis related gene ontology-categories were upregulated in GoF salmon whereas those associated with RNA processing and synthesis, translation and protein folding decreased. Differences were seen also in metabolism and immune function related gene expression. Comparisons of the transcriptomic and proteomic profiles between salmon from GoF and salmon from BMB or BS suggest environmental stressors, especially exposure to environmental contaminants, as a main explanation for differences. Salmon feeding in GoF are thus “disturbed by hazardous substances”. The results may also be applied in evaluating the conditions of pelagic ecosystems in the different parts of Baltic Sea.

Cyclophilin A is not acetylated at Lysine-82 and Lysine-125 in resting and stimulated platelets

Project description:Cyclophilin A (CyPA), a member of the family of cyclophilins, is widely expressed by all prokaryotic and eukaryotic cells. Upon activation, CyPA can also be released from platelets, and engages in extracellular functions via interaction with the CD147 receptor that contribute to cardiovascular disease. CyPA was recently found to be acetylated at K82 and K125, two lysines conserved in most species, and these modifications were required for secretion of acetylated CyPA in response to cell activation in vascular smooth muscle cells. We here addressed whether acetylation at these sitesis also required for release of acetylated CyPA from platelets. Western blot analyses demonstrated the presence of CyPA in human and mouse platelets. Thrombin-stimulation resulted in CyPA release from platelets, however, no acetylation was observed –neither in cell lysates nor in supernatants of untreatedand thrombin-activated platelets. Similar results were obtained after immunoprecipitation of CyPA from platelets. In vitro acetylation of recombinant humanCyPA by p300 acetyltransferase likewise did not induce CyPA acetylation. Using shotgun proteomics we detected two CyPA peptide precursors in the recombinant protein, acetylatedat K28, but again no acetylation was found in CyPA from resting or stimulated platelet samples. Our findings suggest that acetylation of CyPA is not a major protein modification in platelets, and that CyPA acetylation at K82 and K125 is not required for its secretion from platelets.

Expression analysis of TCRgd+LAP+ versus TCRgd+LAP- cells

Project description:We used RNA-Seq to identify differential gene expression in LAP+ vs. LAP- Gamma-delta T-cells. We report a signature of 407 genes that were enriched in TCRgd+LAP+ vs. TCRgd+LAP- cells with p<0.05. Among the up-regulated genes, we found increased expression of genes related to antigen presentation, including MHC class II molecules (H2-Aa, H2-Ab1, H2-Eb1 and H2-Eb2), CD40 and CD86 RNA-Seq of TCRgd+LAP+ versus TCRgd+LAP- cells harvested from mouse spleen and Peyer's patches; began with 20 mice for two independent experiments (10 mice each); samples were pooled and for each experiment resulted in one LAP- and one LAP+ sample for RNA-SEQ, or four samples in total; The two LAP+ were combined, resulting in three samples in total for RNA-Seq.

Topoisomerase I Poisoning by Electrophiles Derived from Oxidative Stress

Project description:The cancer target enyzme topoisomerase 1 transiently cleaves one strand of chromosomal DNA to relax accumulated strain that can prevent transcription, replication or chromatin assembly. The topoisomerase 1 poison camptothecin and its synthetic analogs are widely used chemotherapeutics that act by trapping the enzyme on DNA in a ‘covalent complex’, resulting in persistent DNA damage and cell death. The prevailing model, interfacial inhibition, contends that the covalent complex is trapped by drug binding alone. In contrast, here we show that camptothecins produce extensive oxidative stress and that topoisomerase 1 is reactive with electrophilic second messengers of oxidative damage. We show that blocking oxidative stress in cells inhibits covalent complex formation by camptothecin, while electrophiles such as 4-hydroxynonenal are able to induce covalent complex formation in cells on their own. Towards mechanism of action, we show that 4-hydroxynonenal electrophilically modifies a cysteine within the DNA-binding active site of human topoisomerase 1. Taken together, our results suggest a mechanism in which oxidative stress mediates the effects of many topoisomerase 1 poisons, and suggest that this critical DNA-regulating enzyme may have a dual role as a sensor of cellular redox stress, linking oxidative stress to DNA damage response in cancer cells.

Quantification of calcyclin and heat shock protein 90 in sera from women with and without preeclampsia by mass spectrometry

Project description:Maternal serum levels of calcyclin and heat shock protein 90 were compared throughout pregnancy from the first trimester till term among women with preeclampsia (PE) and age-matched normotensive pregnant controls (C). Serum samples from two different studies, a nested case-control study embedded in the Rotterdam periconception cohort and the Lepra Study both conducted at the Erasmus MC in Rotterdam. They were collected in the first, second and third trimester of pregnancy in 43 patients with preeclampsia, consisting of 20 early-onset and 23 late-onset preeclampsia, and 46 normotensive pregnant controls. A serum based 2D LC-MS assay on Parallel Reaction Monitoring mode using a high resolution tribrid mass spectrometer was used to quantify both calcyclin and heat shock protein 90.

VESTIGIAL-LIKE 1 IS A SHARED TARGETABLE CANCER-PLACENTA ANTIGEN EXPRESSED BY PANCREATIC AND BASAL-LIKE BREAST CANCERS

Project description:Cytotoxic T lymphocyte (CTL)-based cancer immunotherapies have shown great promise for inducing clinical regression by targeting tumor-associated antigens (TAA). To expand the TAA landscape of pancreatic ductal adenocarcinoma (PDAC), we performed tandem mass spectrometry analysis of HLA class I-bound peptides from tumor specimens of 35 PDAC patients. This led to the identification of a shared HLA-A*0101 restricted peptide derived from co-transcriptional activator Vestigial-like 1 (VGLL1), a novel putative TAA demonstrating overexpression in multiple tumor types and low or absent transcript expression in essential normal tissues. VGLL1-specific CTLs isolated and expanded from the blood of a male PDAC patient showed the capacity to recognize and kill in an antigen-specific manner a majority of HLA-A*0101 allogeneic tumor cell lines derived not only from PDAC, but also bladder, ovarian, gastric, lung and basal-like breast cancers. Gene expression profiling revealed that VGLL1 is a member of a unique group of cancer-placenta antigens (CPA) that may constitute immunotherapeutic TAA targets for patients with multiple different cancer types.

Ubiquitin-specific proximity labeling for the identification of E3 ubiquitin ligase substrates

Project description:Protein ubiquitination controls diverse processes within eukaryotic cells, including protein degradation, and is often dysregulated in diseases1. Moreover, protein degraders that redirect ubiquitination activities toward disease targets are an emerging and promising therapeutic class2. Over 600 E3 ubiquitin ligases are expressed in humans3,4, but their substrates remain largely elusive due to a lack of robust methods to identify E3 ligase substrates. Here we report the development of E-STUB (E3 substrate tagging by ubiquitin biotinylation), a ubiquitin-specific proximity labeling method that biotinylates ubiquitinated substrates in proximity to an E3 ligase of interest. E-STUB accurately identifies the direct ubiquitinated targets of protein degraders, including collateral targets and ubiquitylation events that do not exhibit a degradative outcome. It also detects known substrates of E3 ligase cereblon (CRBN) and von Hippel-Lindau (VHL) with high precision. With the ability to elucidate proximal ubiquitination events, E-STUB may facilitate the development of proximity-inducing drugs and act as a generalizable method for E3 substrate mapping.
