• Ancestrally Duplicated Conserved Noncoding Element Suggests Dual Regulatory Roles of HOTAIR in cis and trans 

      Nepal, Chirag; Taranta, Andrzej; Hadzhiev, Yavor; Pundhir, Sachin; Mydel, Piotr Mateusz; Lenhard, Boris; Müller, Ferenc; Andersen, Jesper B. (Journal article; Peer reviewed, 2020-04)
      HOTAIR was proposed to regulate either HoxD cluster genes in trans or HoxC cluster genes in cis, a mechanism that remains unclear. We have identified a 32-nucleotide conserved noncoding element (CNE) as HOTAIR ancient ...
    • Carbamylation of immunoglobulin abrogates activation of the classical complement pathway

      Post-translational modifications of proteins significantly affect their structure and function. The carbamylation of positively charged lysine residues to form neutral homoitrulline occurs primarily under inflammatory ...
    • Development of a novel, high-affinity ssDNA trypsin inhibitor 

      Malicki, Stanislaw; Ksiazek, Miroslaw; Majewski, Pawel; Pecak, Aleksandra; Mydel, Piotr Mateusz; Grudnik, Przemyslaw; Dubin, Grzegorz (Peer reviewed; Journal article, 2019)
      Inhibitors of serine proteases are not only extremely useful in the basic research but are also applied extensively in clinical settings. Using Systematic Evolution of Ligands by Exponential Enrichment (SELEX) approach we ...
    • Discovery of novel potential reversible peptidyl arginine deiminase inhibitor 

      Aliko, Ardita; Kaminska, Marta; Falkowski, Katherine; Bielecka, Ewa; Benedyk-Machaczka, Malgorzata; Malicki, Stanislaw; Koziel, Joanna; Wong, Alicia; Bryzek, Danuta; Kantyka, Tomasz Tadeusz; Mydel, Piotr Mateusz (Peer reviewed; Journal article, 2019)
      Citrullination, a posttranslational modification, is catalyzed by peptidylarginine deiminases (PADs), a unique family of enzymes that converts peptidyl-arginine to peptidyl-citrulline. Overexpression and/or increased PAD ...
    • Inhibition of CDK9 as a therapeutic strategy for inflammatory arthritis 

      Hellvard, Annelie; Zeitlmann, Lutz; Heiser, Ulrich; Kehlen, Astrid; Niestroj, André; Demuth, Hans-Ulrich; Koziel, Joanna; Delaleu, Nicolas; Potempa, Jan; Mydel, Piotr Mateusz (Peer reviewed; Journal article, 2016-08-11)
      Rheumatoid arthritis is characterised by synovial inflammation and proliferation of fibroblast-like synoviocytes. The induction of apoptosis has long been proposed as a target for proliferative autoimmune diseases, and has ...
    • The link between periodontal disease and rheumatoid arthritis: An updated review 

      Koziel, Joanna; Mydel, Piotr Mateusz; Potempa, Jan (Peer reviewed; Journal article, 2014-01)
      Porphyromonas gingivalis is a leading pathogen in chronic periodontitis, a disease process involving progressive destruction of the tissues that support the teeth. Recently, the organism has been reported to produce a ...
    • Microbiological and bioinformatics analysis of primary Sjogren's syndrome patients with normal salivation 

      Siddiqui, Huma; Chen, Tsute; Aliko, Ardita; Mydel, Piotr Mateusz; Jonsson, Roland; Olsen, Ingar (Peer reviewed; Journal article, 2016-10-20)
      Background: Reduced salivation is considered a major clinical feature of most but not all cases of primary Sjögren’s syndrome (pSS). Reduced saliva flow may lead to changes in the salivary microbiota. These changes have ...
    • Structure and mechanism of a bacterial host-protein citrullinating virulence factor, Porphyromonas gingivalis peptidylarginine deiminase 

      Goulas, Theodoros; Mizgalska, Danuta; Garcia-Ferrer, Irene; Kantyka, Tomasz; Guevara, Tibisay; Szmigielski, Borys; Sroka, Aneta; Millan, Claudia; Uson, Isabel; Veillard, Florian; Potempa, Barbara; Mydel, Piotr Mateusz; Sola, Maria; Potempa, Jan; Gomis-Ruth, F. Xavier (Peer reviewed; Journal article, 2015-07-01)
      Citrullination is a post-translational modification of higher organisms that deiminates arginines in proteins and peptides. It occurs in physiological processes but also pathologies such as multiple sclerosis, fibrosis, ...
    • Synoviocyte-targeted therapy synergizes with TNF inhibition in arthritis reversal
