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....
Cholesterol redistribution triggered by CYP46A1 gene therapy improves major hal...
Nunes, Maria João; Carvalho, Andreia N.; Reis, Joana; Costa, Daniela; Moutinho, Miguel; Mateus, Joana; Mendes de Almeida, Rita; Brito, SaraCholesterol 24-hydroxylase (CYP46A1) is an exclusively neuronal cytochrome P450 enzyme responsible for converting cholesterol into 24S-hydroxycholesterol, which serves as the primary pathway for eliminating cholesterol in the brain. We and others have shown that increased activity of CYP46A1 leads to reduced levels of cholesterol and has a positive effect on cognition. Therefore, we hypothesized that CYP46A1 co...
RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabol...
Afonso, Marta B.; Islam, Tawhidul; Magusto, Julie; Amorim, Ricardo; Lenoir, Véronique; Simões, Rui F.; Teixeira, José; Silva, Liana C.Background and Aims: Receptor‐interacting protein kinase 3 (RIPK3) mediates NAFLD progression, but its metabolic function is unclear. Here, we aimed to investigate the role of RIPK3 in modulating mitochondria function, coupled with lipid droplet (LD) architecture in NAFLD. Approach and Results: Functional studies evaluating mitochondria and LD biology were performed in wild‐type (WT) and Ripk3−/− mice fed a cho...
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...
Disclosing the antitumour potential of the marine bromoditerpene sphaerococceno...
Alves, Celso; Silva, Joana; Afonso, Marta B; Guedes, Romina A.; Guedes, Rita C.; Alvariño, Rebeca; Pinteus, Susete; Gaspar, Helena; Goettert, Márcia I.Nature has revealed to be a key source of innovative anticancer drugs. This study evaluated the antitumour potential of the marine bromoditerpene sphaerococcenol A on different cancer cellular models. Dose-response analyses (0.1-100 µM; 24 h) were accomplished in eight different tumour cell lines (A549, CACO-2, HCT-15, MCF-7, NCI-H226, PC-3, SH-SY5Y, SK-MEL-28). Deeper studies were conducted on MFC-7 cells, nam...

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...

Lopes, Joana; Ferreira-Gonçalves, Tânia; Figueiredo, Isabel V.; Rodrigues, Cecília M. P.; Ferreira, Hugo; Ferreira, David; Viana, Ana S.; Faísca, PedroThe global impact of cancer emphasizes the importance of developing innovative, effective and minimally invasive therapies. In the context of superficial cancers, the development of a multifunctional nanoparticle-based system and its in vitro and in vivo safety and efficacy characterization are, herein, proposed as a proof-of-concept. This multifunctional system consists of gold nanoparticles coated with hyalur...
