The myc trilogy: lord of rna polymerases
WebThree new studies now show that the oncoprotein Myc, known to drive cell division, also enhances ribosomal RNA synthesis by RNA polymerase I in addition to controlling RNA polymerase II- and III-regulated gene transcription. This suggests that Myc promotes the generation of crucial components of a functional ribosome. WebJan 1, 2024 · The MYC oncogene broadly promotes transcription mediated by all nuclear RNA polymerases, thereby acting as a positive modifier of global gene expression. Here, we report that MYC stimulates the transcription of DANCR, a long noncoding RNA (lncRNA) that is widely overexpressed in human cancer.
