Extracellular vesicles from pancreatic cancer stem cells lead an intratumor com...
Ruivo, Carolina F.; Bastos, Nuno; Adem, Barbara; Batista, Ines; Duraes, Cecilia; Melo, Carlos A.; Castaldo, Stephanie A.; Campos‐Laborie, FranciscoObjective: Intratumor heterogeneity drives cancer progression and therapy resistance. However, it has yet to be determined whether and how subpopulations of cancer cells interact and how this interaction affects the tumour. Design: We have studied the spontaneous flow of extracellular vesicles (EVs) between subpopulations of cancer cells: cancer stem cells (CSC) and non-stem cancer cells (NSCC). To determine th...
Genome-wide profiling of p53-regulated enhancer RNAs uncovers a subset of enhan...
Léveillé, Nicolas; Melo, Carlos A.; Rooijers, Koos; Díaz-Lagares, Angel; Melo, Sonia A.; Korkmaz, Gozde; Lopes, Rui; Moqadam, Farhad Akbari; Maia, Ana Rp53 binds enhancers to regulate key target genes. Here, we globally mapped p53-regulated enhancers by looking at enhancer RNA (eRNA) production. Intriguingly, while many p53-induced enhancers contained p53-binding sites, most did not. As long non-coding RNAs (lncRNAs) are prominent regulators of chromatin dynamics, we hypothesized that p53-induced lncRNAs contribute to the activation of enhancers by p53. Among ...
