ChIP-seq for Gli1 and Gli2 in chondrosarcoma
Ontology highlight
ABSTRACT: Excessive Hedgehog signaling in chondrocytes is sufficient to cause formation of enchondroma-like lesions in mice which can progress to chondrosarcoma. To elucidate potential mechanisms through which activation of Hedgehog signaling contributes to cartilage tumor formation, we used chromatin immunoprecipitation and next generation sequencing to identify Gli1 and Gli2 target genes in primary human chondrosarcoma. In silico analyses were conducted to identify and characterize Gli1 and Gli2 binding regions, including de novo motif analysis, co-localization with additional transcription factors, distance to transcriptional start site, conservation between human and mouse, and supervised and unsupervised analyses of biological pathways and processes. Our results profile putative unique and overlapping target genes of Gli1 and Gli2 in chondrosarcoma.
