Other claims from this paper (5)
- Intervention effect Hypoxia reduced the average proportion of individual mRNA species in large polysome complexes from 56.1% to 32.1%.
- Observation A significant decrease in association with translational complexes was observed for 77% of mRNAs.
- Observation Fewer than half of the highly induced mRNAs circumvented the global depression of translation.
- Observation A large number of mRNAs, including ribosomal protein mRNAs, had a significant decrease in polysome association without a decrease in steady-state accumulation.
- Mechanism A low GC content of the 5'-untranslated region provides a selective advantage for translation under hypoxia.
