Glycoproteomics identifies HOMER3 as a potentially targetable biomarker trigger...
Peixoto, A; Ferreira, D; Azevedo, R; Freitas, R; Fernandes, E; Relvas-Santos, M; Gaiteiro, C; Soares, J; Cotton, S; Teixeira, B; Paulo, P; Lima, LBackground: Muscle invasive bladder cancer (MIBC) remains amongst the deadliest genitourinary malignancies due to treatment failure and extensive molecular heterogeneity, delaying effective targeted therapeutics. Hypoxia and nutrient deprivation, oversialylation and O-glycans shortening are salient features of aggressive tumours, creating cell surface glycoproteome fingerprints with theranostics potential. Meth...
Target score—a proteomics data selection tool applied to esophageal cancer iden...
Cotton, S; Ferreira, D; Soares, J; Peixoto, A; Relvas-Santos, M; Azevedo, R; Piairo, P; Diéguez, L; Palmeira, C; Lima, L; Silva, AMN; Santos, LLEsophageal cancer (EC) is a life-threatening disease, demanding the discovery of new biomarkers and molecular targets for precision oncology. Aberrantly glycosylated proteins hold tremendous potential towards this objective. In the current study, a series of esophageal squamous cell carcinomas (ESCC) and EC-derived circulating tumor cells (CTCs) were screened by immunoassays for the sialyl-Tn (STn) antigen, a g...
Nucleolin-sle a glycoforms as E-selectin ligands and potentially targetable bio...
Fernandes, E; Freitas, R; Ferreira, D; Soares, J; Azevedo, R; Gaiteiro, C; Peixoto, A; Oliveira, S; Cotton, S; Relvas-Santos, M; Afonso, LP; Palmeira, CBackground: Gastric cancer (GC) is a major health burden worldwide, with half of patients developing metastases within 5 years after treatment, urging novel biomarkers for diagnosis and efficient therapeutic targeting. Sialyl-Lewis A (SLeA), a terminal glycoepitope of glycoproteins and glycolipids, offers tremendous potential towards this objective. It is rarely expressed in healthy tissues and blood cells, whi...
Esophageal, gastric and colorectal cancers: Looking beyond classical serologica...
Fernandes, E; Sores, J; Cotton, S; Peixoto, A; Ferreira, D; Freitas, R; Reis, CA; Santos, LL; Ferreira, JAEsophageal (OC), gastric (GC) and colorectal (CRC) cancers are amongst the digestive track tumors with higher incidence and mortality due to significant molecular heterogeneity. This constitutes a major challenge for patients’ management at different levels, including non-invasive detection of the disease, prognostication, therapy selection, patient’s follow-up and the introduction of improved and safer therape...
