E-GEOD-45437 - Expression data from paediatric ependymoma short-term cell cultures
Released on 2 December 2013, last updated on 3 June 2014
Promoter hypermethylation and transcriptional silencing is a common epigenetic mechanism of tumour suppressor inactivation in cancer, including malignant brain tumours. To identify targets of epigenetic silencing mediated by CpG island methylation in paediatric ependymoma, we used a pharmacological unmasking approach through treatment with the demethylating agent 5-Aza-2’-deoxycytidine followed by global expression microarray analysis. Three short-term ependymoma cell cultures were used for whole genome expression analysis following treatment with the demethylating agent 5-Aza-dC (5 µmol/L) or mock-treated with DMSO (≤0.1% v/v) for 96-hrs.
