Low-dose ionizing radiation induces therapeutic neovascularization in a pre-cli...
Ministro, Augusto; Oliveira, Paula de; Nunes, Raquel J.; Rocha, André dos Santos; Correia, Adriana; Carvalho, Tânia; Rino, José; Faísca, PedroAims: We have previously shown that low-dose ionizing radiation (LDIR) induces angiogenesis but there is no evidence that it induces neovascularization in the setting of peripheral arterial disease. Here, we investigated the use of LDIR as an innovative and non-invasive strategy to stimulate therapeutic neovascularization using a model of experimentally induced hindlimb ischemia (HLI). Methods and results: Afte...
Transthyretin Proteins Regulate Angiogenesis by Conferring Different Molecular ...
Nunes, Raquel J.; Oliveira, Paula de; Lages, Ana; Becker, Jörg D.; Marcelino, Paulo; Barroso, Eduardo; Perdigoto, Rui; Kelly, Jeffery W."Background: The biological effects of transthyretin proteins on vasculature remain unknown. Results: V30M transthyretin tetramer modulates endothelial global gene expression, down-regulating pro-angiogenic genes, inducing apoptosis and inhibiting migration. Conclusion: Transthyretin proteins regulate angiogenesis by conferring different molecular identities to endothelial cells. Significance: This work has cri...

Nunes, Raquel J.; de Oliveira, Paula; Lages, Ana; Becker, Jörg D.; Marcelino, Paulo; Barroso, Eduardo; Perdigoto, Rui; Kelly, Jeffery W.Familial amyloidotic polyneuropathy (FAP) has a high prevalence in Portugal, and the most common form of hereditary amyloidosis is caused by an amyloidogenic variant of transthyretin (TTR) with a substitution of methionine for valine at position 30 (V30M). Until now, the available efficient therapy is liver transplantation, when performed in an early phase of the onset of the disease symptoms. However, transpla...
