Protein and nucleotide biosynthesis are coupled by a single rate-limiting enzyme, PRPS2, to drive cancer.

Cancer cells must integrate multiple biosynthetic demands to drive indefinite proliferation. How these key cellular processes, such as metabolism and protein synthesis, crosstalk to fuel cancer cell growth is unknown. Here, we uncover the mechanism by which the Myc oncogene coordinates the production of the two most abundant classes of cellular macromolecules, proteins, and nucleic acids in cancer cells.

The translational landscape of the mammalian cell cycle.

Gene regulation during cell-cycle progression is an intricately choreographed process, ensuring accurate DNA replication and division. However, the translational landscape of gene expression underlying cell-cycle progression remains largely unknown. Employing genome-wide ribosome profiling, we uncover widespread translational regulation of hundreds of mRNAs serving as an unexpected mechanism for gene regulation underlying cell-cycle progression.
