Bioactive lipids in Dunaliella salina: implications for functional foods and he...
Pais, Rita; Conde, Tiago; Neves, Bruna B.; Pinho, Marisa; Coelho, Marta; Pereira, Hugo; Rodrigues, Alexandre M. C.; Domingues, Pedro; Gomes, Ana MariaDunaliella salina is a green microalga extensively explored for β-carotene production, while knowledge of its lipid composition is still limited and poorly investigated. Among lipids, polar lipids have been highlighted as bioactive phytochemicals with health-promoting properties. This research aimed to provide an in-depth lipidome profiling of D. salina using liquid and gas chromatography coupled with mass spec...
Age-associated metabolic and epigenetic barriers during direct reprogramming of...
Santos, Francisco; Correia, Magda; Dias, Rafaela; Bola, Bárbara; Noberini, Roberta; Ferreira, Rita S.; Trigo, Diogo; Domingues, Pedro; Teixeira, JoséHeart disease is the leading cause of mortality in developed countries, and novel regenerative procedures are warranted. Direct cardiac conversion (DCC) of adult fibroblasts can create induced cardiomyocytes (iCMs) for gene and cell-based heart therapy, and in addition to holding great promise, still lacks effectiveness as metabolic and age-associated barriers remain elusive. Here, by employing MGT (Mef2c, Gata...
Antimicrobial, antioxidant and anti-Inflammatory activities of the mucus of the...
Lopes, Diana; Cunha, Eva; Conde, Tiago; Moreira, Anthony; Cruz, Sónia; Domingues, Pedro; Oliveira, Manuela; Cartaxana, PauloElysia crispata (Sacoglossa, Gastropoda) is a tropical sea slug known for its ability to incorporate functional chloroplasts from a variety of green macroalgae, a phenomenon termed kleptoplasty. This sea slug, amenable to laboratory cultivation, produces mucus, a viscous secretion that serves diverse purposes including protection, locomotion, and reproduction. In this study, we profiled the antimicrobial, antio...

Proteomic analysis of the mucus of the photosynthetic sea slug Elysia crispata
Lopes, Diana; Aveiro, Susana; Cruz, Sónia; Cartaxana, Paulo; Domingues, PedroElysia crispata is a tropical sea slug that can retain intracellular functional chloroplasts from its algae prey, a mechanism termed kleptoplasty. This sea slug, like other gastropods, secretes mucus, a viscous secretion with multiple functions, including lubrication, protection, and locomotion. This study presents the first comprehensive analysis of the mucus proteome of the sea slug E. crispata using gel elec...

Lipidome of extracellular vesicles from Giardia lamblia
Faria, Clarissa Perez; Ferreira, Bárbara; Lourenço, Ágata; Guerra, Inês Calado; Melo, Tânia; Domingues, Pedro; Domingues, Maria do Rosário MarquesExtracellular vesicles (EVs) (exossomes, microvesicles and apoptotic bodies) have been well acknowledged as mediators of intercellular communications in prokaryotes and eukaryotes. Lipids are essential molecular components of EVs but at the moment the knowledge about the lipid composition and the function of lipids in EVs is limited and as for now none lipidomic studies in Giardia EVs was described. Therefore, ...
Lipid profile variability in children at different ages measured in dried blood...
Ferreira, Helena Beatriz; Melo, Tânia; Rocha, Hugo; Paiva, Artur; Domingues, Pedro; Domingues, M. RosárioDried blood spot (DBS) is a minimally invasive sampling technique that has several advantages over conventional venipuncture/arterial blood sampling. More recently, DBS has also been applied for lipidomics analysis, but this is an area that requires further research. The few works found in the literature on lipidomics of DBS samples performed the analysis in adult samples, leaving pediatric ages unmapped. The o...
Mitochondrial metabolism drives low-density lipoprotein-induced breast cancer c...
Nóbrega-Pereira, Sandrina; Santos, Francisco; Santos, Miguel Oliveira; Serafim, Teresa L.; Lopes, Ana Patrícia; Coutinho, Diogo; Carvalho, Filipa S.Most cancer-related deaths are due to metastases. Systemic factors, such as lipid-enriched environments [as low-density lipoprotein (LDL)-cholesterol], favor breast cancer, including triple-negative breast cancer (TNBC) metastasis formation. Mitochondria metabolism impacts TNBC invasive behavior but its involvement in a lipid-enriched setting is undisclosed. Here we show that LDL increases lipid droplets, induc...
