To establish suitable models to investigate KBTBD4, we assessed endogenous CoREST and LSD1 protein levels in five representative medulloblastoma cell lines of different subgroups: D283Med (group 3/4, without reported MYC amplification), HD-MB03 (group 3, MYC amplification), D425Med (group 3, MYC amplification), D458Med (metastatic counterpart of D425Med primary tumour) as well as DAOY (SHH subgroup). This evidence concerns the gene RCOR1 and neoplasm.
