Journal ArticleDOI
Phagocytosing neutrophils down-regulate the expression of chemokine receptors CXCR1 and CXCR2
Tatyana Doroshenko,Yuri V Chaly,Valery Savitskiy,Olga V. Maslakova,Anna Portyanko,I. V. Gorudko,Nikolai N. Voitenok +6 more
TL;DR: Observations suggest that down-regulation of CXCR expression may substantially reduce the responsiveness of phagocytosing neutrophils to CXC chemokines.
Journal ArticleDOI
beta(III)-tubulin at the invasive margin of colorectal cancer: possible link to invasion.
TL;DR: This is the first report documenting a preferential localization of βIII-tubulin in the invading epithelium, and the possibility that changes in tubulin isotypes could modulate the invading activity of cancer cells is raised.
Journal ArticleDOI
Survival-associated heterogeneity of marker-defined perivascular cells in colorectal cancer
Artur Mezheyeuski,Artur Mezheyeuski,Maja Bradic Lindh,Tormod Kyrre Guren,Anca Dragomir,Per Pfeiffer,Elin H. Kure,Tone Ikdahl,Eva Skovlund,Sara Corvigno,Carina Strell,Kristian Pietras,Fredrik Pontén,Jan Mulder,Camilla Qvortrup,Anna Portyanko,Kjell Magne Tveit,Bengt Glimelius,Halfdan Sorbye,Arne Östman +19 more
TL;DR: A novel method for digital quantitative analyses of vessel characteristics and PC was applied to two collections of human metastatic colorectal cancer, which identified host vasculature and oncogenic status as determinants of tumor perivascular features.
Journal ArticleDOI
Image analysis-derived metrics of histomorphological complexity predicts prognosis and treatment response in stage II-III colon cancer
Artur Mezheyeuski,Ina Hrynchyk,Mia Karlberg,Anna Portyanko,Lars Egevad,Peter Ragnhammar,David Edler,Bengt Glimelius,Arne Östman +8 more
TL;DR: A method of computer-aided analysis of tissue sections, relying on multifractal (MF) analyses, of cytokeratin-stained tumor sections which quantitatively evaluates of the morphological complexity of the tumor-stroma interface appears as an attractive and easy-to-implement tool for biomarker identification.
Journal ArticleDOI
Tissue transglutaminase expression in celiac mucosa: an immunohistochemical study
TL;DR: A significant decrease in tTG expression in all the compartments was seen in repeatedly assessed samples, and tissue transglutaminase up-regulation does not seem to be specific for CD and can appear in other pathological conditions.
