Primary malignant bone tumours are rare cancers that are characterised by different genetic and epigenetic alterations. A functional epigenomic approach was combined with the Illumina HumanHT-12.v4-BeadChip expression microarray in three Ewing Sarcoma (ES) cell lines to identify genome-wide functional methylation changes in these cells and ES primary samples. This study revealed eight frequently methylated genes in ES patients’ samples, where NPTX2 and PHF11 promoter methylation was associated with poor patient prognosis. The second methylation study involved genome-wide DNA methylation profiling of chordoma samples using the Infinium-HumanMethylation450-BeadChip microarray. This study identified a list of 8,819 loci which were differentially methylated between chordomas and controls and eight genes which were differentially methylated between recurrent and non-recurrent chordoma samples. RNA sequencing (RNA-seq) analysis of primitive small blue round cell tumour (SBRCT) samples was also carried out in order to identify gene fusions in this type of cancer. Three different somatic gene fusions in SBRCT samples were identified using RNA-Seq (CRTC1-SS18;BCR-UPB1 and KHDRBS2-CIC). Moreover, two other gene fusions were identified in unpaired SBCRT samples. Overall, this study used high-throughput technologies to identify novel genetically and epigenetically altered genes in different types of bone sarcoma which may, therefore, provide unique insight into bone sarcoma tumorigenesis.
