Since in other settings, the bioisosteric replacement of the 1,2,4-triazole moiety with imidazole resulted in significantly more efficient GP inhibitors, in silico calculations using Glide molecular docking along with unbound state DFT calculations were performed on N-(β-Dglucopyranosyl)-arylimidazole-carboxamides, revealing their potential for strong GP inhibition. The syntheses of the target compounds involved the formation of an amide bond between per-O-acetylated β-D-glucopyranosylamine and the corresponding arylimidazole-carboxylic acids. Kinetics experiments on rabbit muscle GPb revealed low micromolar inhibitors, with the best inhibition constants (Kis) of ~3–4 µM obtained for 1- and 2-naphthyl-substituted N-(β-D-glucopyranosyl)-imidazolecarboxamides, 2b–c. The predicted protein–ligand interactions responsible for the observed potencies are discussed and will facilitate the structure-based design of other inhibitors targeting this important therapeutic target.

Thrombospondin-1 (TSP1) protein is one of the master regulators of angiogenesis. This study unveils a novel aspect of TSP1 regulation through reversible phosphorylation. The silencing of the B55α regulatory subunit of protein phosphatase 2A (PP2A) in endothelial cells led to a significant decrease in TSP1 expression. Direct interaction between TSP1 and PP2A-B55α was confirmed via various methods. Truncated TSP1 constructs were employed to identify the phosphorylation site and the responsible kinase, ultimately pinpointing PKC as the enzyme phosphorylating TSP1 on Ser93. The biological effects of B55α–TSP1 interaction were also analyzed. B55α silencing not only counteracted the increase in TSP1 expression during wound closure but also prolonged wound closure time. Although B55α silenced cells initiated tube-like structures earlier than control cells, their spheroid formation was disrupted, leading to disintegration. Cells transfected with phosphomimic TSP1 S93D exhibited smaller spheroids and reduced effectiveness in tube formation, revealing insights into the effects of TSP1 phosphorylation on angiogenic properties. In this paper, we introduce a new regulatory mechanism of angiogenesis by reversible phosphorylation on TSP1 S93 by PKC and PP2A B55α.}, year = {2024}, eissn = {1422-0067}, pages = {1844} } @article{MTMT:34483936, title = {Cell-free ascites from ovarian cancer patients induces Warburg metabolism and cell proliferation through TGFbeta-ERK signalling}, url = {https://m2.mtmt.hu/api/publication/34483936}, author = {Szeőcs, Dóra and Vida, Beáta and Petővári, Gábor and Póliska, Szilárd and Janka, Eszter Anna and Sipos, Adrienn and Uray (Davis), Karen L. and Sebestyén, Anna and Krasznai, Zoárd Tibor and Bay, Péter}, doi = {10.1007/s11357-023-01056-1}, journal-iso = {GEROSCIENCE}, journal = {GEROSCIENCE: OFFICIAL JOURNAL OF THE AMERICAN AGING ASSOCIATION (AGE)}, unique-id = {34483936}, issn = {2509-2715}, abstract = {Ascites plays a key role in supporting the metastatic potential of ovarian cancer cells. Shear stress and carry-over of cancer cells by ascites flow support carcinogenesis and metastasis formation. In addition, soluble factors may participate in the procarcinogenic effects of ascites in ovarian cancer. This study aimed to determine the biological effects of cell-free ascites on carcinogenesis in ovarian cancer cells. Cell-free ascites from ovarian cancer patients (ASC) non-selectively induced cell proliferation in multiple models of ovarian cancer and untransformed primary human dermal fibroblasts. Furthermore, ASC induced a Warburg-type rearrangement of cellular metabolism in A2780 ovarian cancer cells characterized by increases in cellular oxygen consumption and glycolytic flux; increases in glycolytic flux were dominant. ASC induced mitochondrial uncoupling and fundamentally reduced fatty acid oxidation. Ascites-elicited effects were uniform among ascites specimens. ASC-elicited transcriptomic changes in A2780 ovarian cancer cells included induction of the TGF beta-ERK/MEK pathway, which plays a key role in inducing cell proliferation and oncometabolism. ASC-induced gene expression changes, as well as the overexpression of members of the TGF beta signaling system, were associated with poor survival in ovarian cancer patients. We provided evidence that the activation of the autocrine/paracrine of TGF beta signaling system may be present in bladder urothelial carcinoma and stomach adenocarcinoma. Database analysis suggests that the TGF beta system may feed forward bladder urothelial carcinoma and stomach adenocarcinoma. Soluble components of ASC support the progression of ovarian cancer. These results suggest that reducing ascites production may play an essential role in the treatment of ovarian cancer by inhibiting the progression and reducing the severity of the disease.}, year = {2024}, eissn = {2509-2723}, orcid-numbers = {Petővári, Gábor/0000-0002-1957-2864; Janka, Eszter Anna/0000-0003-0724-5281; Sebestyén, Anna/0000-0001-8814-4794} } @article{MTMT:34148390, title = {Distinct subsets of anti-pulmonary autoantibodies correlate with disease severity and survival in severe COVID-19 patients}, url = {https://m2.mtmt.hu/api/publication/34148390}, author = {Tóth, Emese and Fagyas, Miklós and Nagy, Béla and Siket, Ivetta Mányiné and Szőke, Blanka and Mártha, Lilla and Mahdi, Mohamed and Erdősi, Gábor and Pólik, Zsófia and Kappelmayer, János and Papp, Zoltán and Borbély, Attila and Szabó, Tamás and Balla, József and Balla, György and Bácsi, Attila and Szekanecz, Zoltán and Bay, Péter and Tóth, Attila}, doi = {10.1007/s11357-023-00887-2}, journal-iso = {GEROSCIENCE}, journal = {GEROSCIENCE: OFFICIAL JOURNAL OF THE AMERICAN AGING ASSOCIATION (AGE)}, volume = {46}, unique-id = {34148390}, issn = {2509-2715}, abstract = {Autoantibodies targeting the lung tissue were identified in severe COVID-19 patients in this retrospective study.
