In SCLC cell lines, loss of RB1 results in E2F7 upregulation and epigenetic silencing of YAP [90], which is mediated by the RCOR-HDAC1/2-KDM1A co-repressor (CoREST) complex, although the requirement of KDM1A may vary between different cell lines [90,91]. This evidence concerns the gene KDM1A and small cell lung carcinoma.
