FRZB-induced anti-angiogenic effect via Caveolin-1-mediated TGFβ signalling.
Journal Article Nat Commun · April 7, 2026 Pathological neovascularization and vascular leakage are central drivers of many sight-threatening diseases. While strategies targeting vascular endothelial growth factor (VEGF) have improved clinical outcomes, many patients do not benefit from the treatme ...

Journal Article J Clin Invest · February 2, 2026 GATA6 is a master regulator of differentiation in the pancreas, and its expression levels determine the 2 main molecular subtypes of pancreatic cancer. High GATA6 levels contribute to the classical pancreatic cancer subtype, which is associated with a high ...

Journal Article FEBS J · January 28, 2026 Wnt signaling regulates metazoan development and homeostasis, in part by β-catenin-dependent activation and repression of a large number of genes. However, Wnt signaling also regulates genes independent of β-catenin, genes that are less well-characterized. ... Full text Link to item CiteRecent Grants
