abstract = {Aggregation of the Tar DNA-binding protein of 43 kDa
(TDP-43) is a pathological hallmark of amyotrophic lateral
sclerosis and frontotemporal dementia and likely contributes
to disease by loss of nuclear function. Analysis of TDP-43
function in knockout zebrafish identified an endothelial
directional migration and hypersprouting phenotype during
development prior lethality. In human umbilical vein cells
(HUVEC) the loss of TDP-43 leads to hyperbranching. We
identified elevated expression of FIBRONECTIN 1 (FN1), the
VASCULAR CELL ADHESION MOLECULE 1 (VCAM1), as well as their
receptor INTEGRIN α4β1 (ITGA4B1) in HUVEC cells.
Importantly, reducing the levels of ITGA4, FN1, and VCAM1
homologues in the TDP-43 loss-of-function zebrafish rescues
the angiogenic defects indicating the conservation of human
and zebrafish TDP-43 function during angiogenesis. Our study
identifies a novel pathway regulated by TDP-43 important for
angiogenesis during development.},
