Post-transcriptional regulation of Ribosome Biogenesis during differentiation [SLAM-seq]

ABSTRACT: The regulation of ribosome biogenesis is a critical component of cell differentiation. Although ribosome biogenesis is well known to be regulated at the transcriptional level, its post-transcriptional regulation is less well understood. A key component of RNA post-transcriptional regulation is transcript decay rate which, together with the rate of synthesis, defines the abundance of the transcripts. Here we measured the stability of the whole transcriptome of P19 cells before differentiation (D0) and six days after the onset of differentiation (D6). We found that while global decay rates dropped during differentiation, the stability of transcripts encoding for ribosomal proteins remains significantly high throughout the differentiation process. These results indicate a strong and specific post-transcriptional regulation of ribosome biogenesis transcripts that is sustained during cell differentiation.
