Methylation of osteosarcoma patients
收藏资源简介：
Osteosarcoma is the most common primary malignant tumour of bone occurring in children and young adolescents. Osteosarcoma is characterized by considerable phenotypic and genomic heterogeneity, and few recurrent targetable genetic changes have been reported. Osteosarcoma exhibits a complex karyotype with high genomic and chromosomal instability; and harbours multiple rearrangements across the genome, kataegis and chromothripsis as well as epigenetic changes. Here we have performed DNA methylation profiling on 10 osteosarcoma patient samples and four bones using the Infinium HumanMethylation450 BeadChip from Illumina, covering 485,000 CpG sites across the genome.
