Coffee cysteine proteinases and related inhibitors with high expression during grain maturation and germination

BMC Plant Biology, 2012
Background Cysteine proteinases perform multiple functions in seeds, including participation in remodelling polypeptides and recycling amino acids during maturation and germination.

Relation between asymptomatic proteinase 3 antibodies and future granulomatosis with polyangiitis.

American Society of Nephrology. Clinical Journal, 2013
BACKGROUND AND OBJECTIVES The subclinical pathogenesis of granulomatosis with polyangiitis (GPA) has not been completely elucidated. Proteinase 3 (PR3) antibodies are strongly associated with GPA, but have not been evaluated before disease presentation.

ERBIN limits epithelial cell plasticity via suppression of TGF‐β signaling

FEBS Letters, EarlyView.
In breast and lung cancer patients, low ERBIN expression correlates with poor clinical outcomes. Here, we show that ERBIN inhibits TGF‐β‐induced epithelial‐to‐mesenchymal transition in NMuMG breast and A549 lung adenocarcinoma cell lines. ERBIN suppresses TGF‐β/SMAD signaling and reduces TGF‐β‐induced ERK phosphorylation.

A Monoclonal Antibody (MCPR3-7) Interfering with the Activity of Proteinase 3 by an Allosteric Mechanism*

Journal of Biological Chemistry, 2013
Background: Proteinase 3 is an abundant serine protease with high similarity to neutrophil elastase and a major autoimmune target in systemic vasculitis. Results: We identified a monoclonal antibody that inhibits PR3 activity.

MET variants with activating N‐lobe mutations identified in hereditary papillary renal cell carcinomas still require ligand stimulation

Molecular Oncology, EarlyView.
MET variants in the N‐lobe of the kinase domain, found in hereditary papillary renal cell carcinoma, require ligand stimulation to promote cell transformation, in contrast to other RTK variants. This suggests that HGF expression in the microenvironment is important for tumor growth in such patients. Their sensitivity to MET inhibitors opens the way for

A novel in vitro cell model of the proteinase/antiproteinase balance observed in alpha-1 antitrypsin deficiency

Frontiers in Pharmacology
Background: Alpha-1 antitrypsin deficiency (AATD) is a genetic condition resulting from mutations in the alpha-1 antitrypsin (AAT) protein, a major systemic antiproteinase, resulting in reduced/no release of AAT, disrupting the proteinase/antiproteinase ...

Renal survival in proteinase 3 and myeloperoxidase ANCA-associated systemic vasculitis.

American Society of Nephrology. Clinical Journal, 2013
BACKGROUND AND OBJECTIVES This study evaluated predictors for patient and renal survival in patients with ANCA-associated vasculitis (AAV) with and without renal involvement.

TOMM20 as a driver of cancer aggressiveness via oxidative phosphorylation, maintenance of a reduced state, and resistance to apoptosis

Molecular Oncology, EarlyView.
TOMM20 increases cancer aggressiveness by maintaining a reduced state with increased NADH and NADPH levels, oxidative phosphorylation (OXPHOS), and apoptosis resistance while reducing reactive oxygen species (ROS) levels. Conversely, CRISPR‐Cas9 knockdown of TOMM20 alters these cancer‐aggressive traits.

The plasma proteome reveals distinct signaling pathways associated with PR3-ANCA positive and MPO-ANCA positive vasculitis

Frontiers in Immunology
ObjectiveDespite recent advances, the pathophysiological mechanisms underlying anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) remain incompletely understood, and comparative proteomic analyses of AAV subtypes are lacking.

Classification of antineutrophil cytoplasmic autoantibody vasculitides: the role of antineutrophil cytoplasmic autoantibody specificity for myeloperoxidase or proteinase 3 in disease recognition and prognosis.

Arthritis & Rheumatism, 2012
OBJECTIVE To compare the usefulness of 3 currently used classification systems in predicting the outcomes of treatment resistance, disease relapse, end-stage renal disease (ESRD), and death in patients with antineutrophil cytoplasmic antibody (ANCA ...
