Mechanosignalling pathways that regulate endothelial barrier function (2023)
Journal Article
McQueen, A., & Warboys, C. M. (2023). Mechanosignalling pathways that regulate endothelial barrier function. Current Opinion in Cell Biology, 84, 102213. https://doi.org/10.1016/j.ceb.2023.102213

Blood vessels are lined by a single layer of endothelial cells that provide a barrier between circulating plasma and the underlying tissue. Permeability of endothelial cells is tightly regulated, and increased permeability is associated with a number...

Disturbed flow increases endothelial inflammation and permeability via a Frizzled-4-β-catenin-dependent pathway (2023)
Journal Article
Rickman, M., Ghim, M., Pang, K., von Huelsen Rocha, A. C., Drudi, E. M., Sureda-Vives, M., …Warboys, C. M. (in press). Disturbed flow increases endothelial inflammation and permeability via a Frizzled-4-β-catenin-dependent pathway. Journal of Cell Science, https://doi.org/10.1242/jcs.260449

Multidirectional or disturbed flow promotes endothelial dysfunction and is associated with early atherogenesis. Here we investigated the role of Wnt signalling in flow-mediated endothelial dysfunction. The expression of Frizzled-4 was higher in cultu...

Shear-mediated ALK5 expression regulates endothelial activation (2023)
Journal Article
Pang, K. T., Ghim, M., Sarathchandra, P., Warboys, C. M., Yacoub, M. H., Chester, A. H., & Weinberg, P. D. (2023). Shear-mediated ALK5 expression regulates endothelial activation. Biochemical and Biophysical Research Communications, 642, 90-96. https://doi.org/10.1016/j.bbrc.2022.12.058

Calcific aortic valve disease affects the aortic side of the valve, exposed to low magnitude multidirectional (“disturbed) blood flow, more than it affects the ventricular side, exposed to high magnitude uniaxial flow. Overt disease is preceded by en... Read More about Shear-mediated ALK5 expression regulates endothelial activation.

NO Synthesis but Not Apoptosis, Mitosis or Inflammation Can Explain Correlations between Flow Directionality and Paracellular Permeability of Cultured Endothelium (2022)
Journal Article
Ghim, M., Yang, S., David, K. R. Z., Eustaquio, J., Warboys, C. M., & Weinberg, P. D. (2022). NO Synthesis but Not Apoptosis, Mitosis or Inflammation Can Explain Correlations between Flow Directionality and Paracellular Permeability of Cultured Endothelium. International Journal of Molecular Sciences, 23(15), 8076. https://doi.org/10.3390/ijms23158076

Haemodynamic wall shear stress varies from site to site within the arterial system and is thought to cause local variation in endothelial permeability to macromolecules. Our aim was to investigate mechanisms underlying the changes in paracellular per...

S1P in the development of atherosclerosis: roles of haemodynamic wall shear stress and endothelial permeability (2021)
Journal Article
Warboys, C. M., & Weinberg, P. D. (2021). S1P in the development of atherosclerosis: roles of haemodynamic wall shear stress and endothelial permeability. Tissue Barriers, https://doi.org/10.1080/21688370.2021.1959243

Atherosclerosis is characterised by focal accumulations of lipid within the arterial wall, thought to arise from effects of haemodynamic wall shear stress (WSS) on endothelial permeability. Identifying pathways that mediate effects of shear on permea... Read More about S1P in the development of atherosclerosis: roles of haemodynamic wall shear stress and endothelial permeability.

β-catenin promotes endothelial survival by regulating eNOS activity and flow-dependent anti-apoptotic gene expression (2020)
Journal Article
Tajadura, V., Hansen, M. H., Smith, J., Charles, H., Rickman, M., Farrell-Dillon, K., …Ferro, A. (2020). β-catenin promotes endothelial survival by regulating eNOS activity and flow-dependent anti-apoptotic gene expression. Cell Death and Disease, 11(6), https://doi.org/10.1038/s41419-020-2687-6

Increased endothelial cell (EC) apoptosis is associated with the development of atherosclerotic plaques that develop predominantly at sites exposed to disturbed flow (DF). Strategies to promote EC survival may therefore represent a novel therapeutic a...

Understanding mechanobiology in cultured endothelium: A review of the orbital shaker method (2019)
Journal Article
Warboys, C. M., Ghim, M., & Weinberg, P. D. (2019). Understanding mechanobiology in cultured endothelium: A review of the orbital shaker method. Atherosclerosis, 285, 170-177. https://doi.org/10.1016/j.atherosclerosis.2019.04.210

A striking feature of atherosclerosis is its highly non-uniform distribution within the arterial tree. This has been attributed to variation in the haemodynamic wall shear stress (WSS) experienced by endothelial cells, but the WSS characteristics tha...

Disturbed flow promotes endothelial senescence via a p53-dependent pathway (2014)
Journal Article
Warboys, C. M., De Luca, A., Amini, N., Luong, L., Duckles, H., Hsiao, S., …Evans, P. C. (2014). Disturbed flow promotes endothelial senescence via a p53-dependent pathway. Arteriosclerosis, Thrombosis, and Vascular Biology, 34(5), 985-995. https://doi.org/10.1161/ATVBAHA.114.303415

Although atherosclerosis is associated with systemic risk factors such as age, high cholesterol, and obesity, plaque formation occurs predominately at branches and bends that are exposed to disturbed patterns of blood flow. The molecular mechanisms t... Read More about Disturbed flow promotes endothelial senescence via a p53-dependent pathway.
