Nucleolin Overexpression Predicts Patient Prognosis While Providing a Framework...
Fernandes, Ângela Valério; Fonseca, Nuno A.; Gonçalves, Nélio; Cruz, Ana F.; Pereira, Marta I.; Gregório, Ana C.; Moura, Vera; Ladeirinha, Ana F.Notwithstanding the advances in the treatment of lung cancer with immune checkpoint inhibitors, the high percentage of non-responders supports the development of novel anticancer treatments. Herein, the expression of the onco-target nucleolin in patient-derived pulmonary carcinomas was characterized, along with the assessment of its potential as a therapeutic target. The clinical prognostic value of nucleolin f...
Cell surface Nucleolin represents a novel cellular target for neuroblastoma the...
Brignole, Chiara; Bensa, Veronica; Fonseca, Nuno A.; Del Zotto, Genny; Bruno, Silvia; Cruz, Ana F.; Malaguti, Fabiana; Carlini, Barbara; Morandi, FabioNeuroblastoma (NB) represents the most frequent and aggressive form of extracranial solid tumor of infants. Nucleolin (NCL) is a protein overexpressed and partially localized on the cell surface of tumor cells of adult cancers. Little is known about NCL and pediatric tumors and nothing is reported about cell surface NCL and NB. Methods: NB cell lines, Schwannian stroma-poor NB tumors and bone marrow (BM)-infilt...
The Enhanced Efficacy of Intracellular Delivery of Doxorubicin/C6-Ceramide Comb...
Cruz, Ana F.; Caleiras, Mariana B.; Fonseca, Nuno A.; Gonçalves, Nélio; Mendes, Vera M.; Sampaio, Susana F.; Moura, Vera; Melo, Joana B.Targeting multiple cellular populations is of high therapeutic relevance for the tackling of solid tumors heterogeneity. Herein, the ability of pegylated and pH-sensitive liposomes, functionalized with the nucleolin-binding F3 peptide and containing doxorubicin (DXR)/C6-ceramide synergistic combination, to target, in vitro, ovarian cancer, including ovarian cancer stem cells (CSC), was assessed. The underlying ...
GMP-grade nanoparticle targeted to nucleolin downregulates tumor molecular sign...
Fonseca, Nuno A.; Gregório, Ana C.; Mendes, Vera M.; Lopes, Rui; Abreu, Teresa; Gonçalves, Nélio; Manadas, Bruno; Lacerda, Manuela; Figueiredo, PauloPatients with breast or ovarian cancer have not benefited from improved efficacy with pegylated liposomal doxorubicin relative to free drug, likely due to the limited extent of the enhanced permeability and retention (EPR) effect, further compromising drug bioavailability in the tumor. Herein it is hypothesized that targeting nucleolin overexpressed in tumor endothelial cells (readily accessible from the vascul...
The InBIO barcoding initiative database: DNA barcodes od portuguese Diptera 01
Ferreira, Sónia A.; Andrade, Rui; Gonçalves, Ana R.; Sousa, Pedro; Paupério, Joana; Fonseca, Nuno A.; Beja, PedroThe InBIO Barcoding Initiative (IBI) Diptera 01 dataset contains records of 203 specimens of Diptera. All specimens have been morphologically identified to species level, and belong to 154 species in total. The species represented in this dataset correspond to about 10% of continental Portugal dipteran species diversity. All specimens were collected north of the Tagus river in Portugal. Sampling took place from...
Inoculated Cell Density as a Determinant Factor of the Growth Dynamics and Meta...
Gregório, Ana C.; Fonseca, Nuno A.; Moura, Vera; Lacerda, Manuela; Figueiredo, Paulo; Simões, Sérgio; Dias, Sérgio; Moreira, João Nuno4T1 metastatic breast cancer model have been widely used to study stage IV human breast cancer. However, the frequent inoculation of a large number of cells, gives rise to fast growing tumors, as well as to a surprisingly low metastatic take rate. The present work aimed at establishing the conditions enabling high metastatic take rate of the triple-negative murine 4T1 syngeneic breast cancer model. An 87% 4T1 t...

On the use of dexamethasone-loaded liposomes to induce the osteogenic different...
Monteiro, Nelson; Martins, Albino; Ribeiro, Diana Margarida da Costa; Faria, Susana; Fonseca, Nuno A.; Moreira, João N.; Reis, R. L.; Neves, N. M.Stem cells have received considerable attention by the scientific community because of their potential for tissue engineering and regenerative medicine. The most frequently used method to promote their differentiation is supplementation of the in vitro culture medium with growth/differentiation factors (GDFs). The limitations of that strategy caused by the short half-life of GDFs limit its efficacy in vivo and ...
Antibacterial activity of chitosan nanofiber meshes with liposomes immobilized ...
Monteiro, Nelson; Martins, Margarida; Martins, Albino; Fonseca, Nuno A.; Moreira, João N.; Reis, R. L.; Neves, N. M.Chitsan (Ch) nanofiber mesh (NFM) is a material with natural characteristics favoring its use in human wound dressing. The present work proposes a gentamicin-loaded liposome immobilized at the surface of Ch NFMs to promote its antibacterial activity. To achieve this purpose, Ch NFMs were functionalized with thiol groups, and gentamicin-loaded liposomes were covalently immobilized by the reaction of the SH group...
Instructive nanofibrous scaffold comprising runt-related transcription factor 2...
Monteiro, Nelson; Ribeiro, Diana Margarida da Costa; Martins, Albino; Faria, Susana; Fonseca, Nuno A.; Moreira, João N.; Reis, R. L.; Neves, N. M.Inducer molecules capable of regulating mesenchymal stem cells (MSCs) differentiation into specific lineages have proven effective in basic science and in preclinical studies. Runt-related transcription factor 2 (RUNX2) is considered to be the central gene involved in the osteoblast phenotype induction, which may be advantageous for inducing bone tissue regeneration. This work envisions the development of a pla...
