The Myc trilogy: lord of RNA polymerases
Cancer cells have a raised cellular metabolism, including increased protein biosynthesis. Three 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.
