Genome-wide mRNA and miRNA expression data analysis to screen for markers involved in sarcomagenesis in human chondrosarcoma cell lines.

Genes and miRNAs involved in sarcomagenesis related pathways are unknown and therefore signaling events leading to mesenchymal cell transformation to sarcoma are poorly elucidated. Exiqon and Illumina microarray study on human chondrosarcoma JJ012 and chondrocytes C28 cell lines to compare and analyze the differentially expressed miRNAs and their gene targets was recently published in the Journal Tumor Biology in 2014. Here we describe in details the contents and quality controls for the miRNA and gene expression data associated with the study that is relevant to this dataset.
