Proteome Profiling of Breast Tumors by Gel Electrophoresis and Nanoscale Electrospray Ionization Mass Spectrometry [PDF]

open access: yes, 2008
We have conducted proteome-wide analysis of fresh surgery specimens derived from breast cancer patients, using an approach that integrates size-based intact protein fractionation, nanoscale liquid separation of peptides, electrospray ion trap mass ...

The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

open access: yesThe FEBS Journal, EarlyView.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.

The Intersection of Protein Disulfide Isomerase and Cancer Associated Thrombosis

open access: yesThrombosis Research, 2018
The mechanisms underlying the hypercoagulability of cancer are complex and include the upregulation coagulation factors or procoagulant proteins, shedding of microparticles, and direct activation of vascular cells.

Multiple protein disulfide isomerases support thrombosis [PDF]

open access: yesCurrent Opinion in Hematology, 2018
Purpose of review The present review provides an overview of recent findings on new members of the protein disulfide isomerase (PDI) family required for thrombosis. Recent findings Twenty years ago PDI was shown to mediate platelet aggregation, and 10 years ago PDI was shown to ...

Biogenesis of TNF‐α‐insights into proteostasis and inflammation

open access: yesThe FEBS Journal, EarlyView.
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Identification of protein disulfide isomerase 1 as a key isomerase for disulfide bond formation in apolipoprotein B100

open access: yesMolecular Biology of the Cell, 2015
Apolipoprotein (apo) B is an obligatory component of very low density lipoprotein (VLDL), and its cotranslational and posttranslational modifications are important in VLDL synthesis, secretion, and hepatic lipid homeostasis. ApoB100 contains 25 cysteine residues and eight disulfide bonds. Although these disulfide bonds were suggested to be important in

Cloning, expression, purification and characterization of a DsbA-like protein from Wolbachia pipientis [PDF]

open access: yes, 2008
Wolbachia pipientis are obligate endosymbionts that infect a wide range of insect and other arthropod species. They act as reproductive parasites by manipulating the host reproduction machinery to enhance their own transmission. This unusual phenotype is

From the Proteome to Therapeutics: A Multi‐Database Approach to Drug Discovery in Periodontitis—An Exploratory Pilot Study

open access: yesJournal of Clinical Periodontology, EarlyView.
ABSTRACT Introduction This explanatory pilot study presents a workflow to identify approved drugs, which could be repurposed for periodontitis therapy using salivary proteomics combined with drug‐target database screening. Methods Proteomic analyses of saliva using LC–MS/MS were conducted in two independent settings: a cohort (sub‐study I, N = 187) and

Kinetic-based trapping by intervening sequence variants of the active sites of protein-disulfide isomerase identifies platelet protein substrates

open access: yesJournal of Biological Chemistry, 2017
Thiol isomerases such as protein-disulfide isomerase (PDI) direct disulfide rearrangements required for proper folding of nascent proteins synthesized in the endoplasmic reticulum.

A substrate-driven allosteric switch that enhances PDI catalytic activity

open access: yesNature Communications, 2016
Protein Disulfide Isomerase (PDI) is a prothrombotic, multidomain enzyme with separate substrate binding and catalytic domains. Here, the authors identify a new class of compounds that target the PDI substrate binding site, inducing a conformational ...
