Primary bile acid shapes peripheral immunity in inflammatory bowel disease-asso...
Santos, André A.; Pires, David; Marques, Vanda; Alesina, Nicole; Herraez, Elisa; Roudnický, Pavel; Rodrigues, Pedro M.; Godinho-Santos, AnaPrimary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease often associated with underlying inflammatory bowel disease (IBD). This study investigates how PSC predisposes individuals to altered inflammatory immune responses compared with IBD alone. A case–control study was conducted with a cohort of 75 patients, including 16 with PSC (14 with concomitant IBD), 39 with IBD alone, and 20 controls....
Preclinical validation of a new hybrid molecule loaded in liposomes for melanom...
Pinho, Jacinta O.; Matias, Mariana; Marques, Vanda; Eleutério, Carla; Fernandes, Célia; Gano, Lurdes; Amaral, Joana D.; Mendes, EduardaThe aggressiveness of melanoma and lack of effective therapies incite the discovery of novel strategies. Recently, a new dual acting hybrid molecule (HM), combining a triazene and a ʟ-tyrosine analogue, was synthesized. HM was designed to specifically be activated by tyrosinase, the enzyme involved in melanin biosynthesis and overexpressed in melanoma. HM displayed remarkable superior antiproliferative activity...
The Role of Rosmarinic Acid on the Bioproduction of Gold Nanoparticles as Part ...
Ferreira-Gonçalves, Tânia; Gaspar, Maria Manuela; Coelho, João M. P.; Marques, Vanda; Viana, Ana S.; Ascensão, Lia; Carvalho, LinaBreast cancer is a high-burden malignancy for society, whose impact boosts a continuous search for novel diagnostic and therapeutic tools. Among the recent therapeutic approaches, photothermal therapy (PTT), which causes tumor cell death by hyperthermia after being irradiated with a light source, represents a high-potential strategy. Furthermore, the effectiveness of PTT can be improved by combining near infrar...
Metabolic cues in cancer diagnosis and therapeutics
Marques, VandaThe worldwide social and economic impact of cancer keeps increasing and proper disease management is a critical step to reducing the cancer burden on society, where appropriate diagnosis, staging, and treatment are key factors. Concomitantly, the increasing prevalence of obesity brings forward its importance as a risk factor for cancer development but also allows to explore associated metabolites and signaling ...

Adiponectin, Leptin, and IGF-1 are useful diagnostic and stratification biomark...
Marques, Vanda; Afonso, Marta; Bierig, Nina; Duarte-Ramos, Filipa; Santos-Laso, Álvaro; Jimenez-Agüero, Raul; Eizaguirre, Emma; Bujanda, LuisBackground: Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease where liver biopsy remains the gold standard for diagnosis. Here we aimed to evaluate the role of circulating adiponectin, leptin, and insulin-like growth factor 1 (IGF-1) levels as non-invasive NAFLD biomarkers and assess their correlation with the metabolome. Materials and Methods: Leptin, adiponectin, and IGF-1 seru...
Antitumour Potential of Gigartina pistillata Carrageenans against Colorectal Ca...
Cotas, João; Marques, Vanda; Afonso, Marta B.; Rodrigues, Cecília M. P.; Pereira, LeonelGigartina pistillata is a red seaweed common in Figueira da Foz, Portugal. Here, the antitumour potential of G. pistillata carrageenan, with a known variable of the life cycle, the female gametophyte (FG) and tetrasporophyte (T) was evaluated against colorectal cancer stem cell (CSC) -enriched tumourspheres. FTIR-ATR analysis of G. pistillata carrageenan extracts indicated differences between life cycle phases,...
Characterization of gastric cells infection by diverse Helicobacter pylori stra...
Marques, Vanda; Ribeiro Da Cunha, Bernardo; Couto, Andreia; Sampaio, Pedro; Fonseca, Luís P. P.; Aleixo, Sandra; Calado, CecíliaThe infection of Helicobacter pylori, covering 50% of the world-population, leads to diverse gastric diseases as ulcers and cancer along the life-time of the human host. To promote the discovery of biomarkers of bacterial infection, in the present work, Fourier-transform infrared spectra were acquired from adenocarcinoma gastric cells, incubated with H. pylori strains presenting different genotypes concerning t...
High resolution melting: improvements in the genetic diagnosis of hypertrophic ...
Santos, Susana; Marques, Vanda; Pires, Marina Joana Dias; Silveira, Leonor; Oliveira, Helena; Lança, Vasco; Brito, Dulce; Madeira, HugoBackground: Hypertrophic Cardiomyopathy (HCM) is a complex myocardial disorder with a recognized genetic heterogeneity. The elevated number of genes and mutations involved in HCM limits a gene-based diagnosis that should be considered of most importance for basic research and clinical medicine. Methodology: In this report, we evaluated High Resolution Melting (HRM) robustness, regarding HCM genetic testing, by ...
