Circulating cell-free DNA methylation mirrors alterations in cerebral patterns ...
Martins-Ferreira, Ricardo; Leal, Bárbara; Chaves, João; Ciudad, Laura; Samões, Raquel; Martins da Silva, António; Pinho Costa, Paulo; Ballestar, EstebanBackground: DNA methylation profiling of circulating cell-free DNA (cfDNA) has rapidly become a promising strategy for biomarker identification and development. The cell-type-specific nature of DNA methylation patterns and the direct relationship between cfDNA and apoptosis can potentially be used non-invasively to predict local alterations. In addition, direct detection of altered DNA methylation patterns perf...
Epilepsy progression is associated with cumulative DNA methylation changes in i...
Martins-Ferreira, Ricardo; Leal, Bárbara; Chaves, João; Li, Tianlu; Ciudad, Laura; Rangel, Rui; Santos, Agostinho; Martins da Silva, AntónioMesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) is the most common focal epilepsy in adults. It is characterized by alarming rates of pharmacoresistance. Epileptogenesis is associated with the occurrence of epigenetic alterations, and the few epigenetic studies carried out in MTLE-HS have mainly focused on the hippocampus. In this study, we obtained the DNA methylation profiles from both the ...
