The promoter-associated noncoding RNA PNCCCND1_B assembles a protein–RNA complex to regulate cyclin D1 transcription in Ewing sarcoma
Most Ewing sarcomas are characterized by the in-frame chromosomal translocation t(11;22) generating the EWS–FLI1 oncogene. EWS–FLI1 protein interacts with the RNA helicase DHX9 and affects transcription and processing of genes involved in neoplastic transformation, including CCND1 (the cyclin D1 gene), which contributes to cell-cycle dysregulation in cancer.
