Summary (written by the submitters)
Processing bodies (P-bodies) are the membraneless organelles that play a critical role in RNA storage and degradation. P-body abnormalities contribute to diseases and developmental disorders, however, the dynamics of RNA components of P-bodies in human embryonic stem cells during maintenance and differentiation remain elusive. Here, we captured P-bodies during human embryonic stem cells(hESCs) to mesodermal differentiation using flow cytometry, and revealing unique transcriptomic features to other organelles and characterized by lower GC content and reduced M6A modifications.
Read the full summary ↓
Genes enriched in P-body are cell-specific, mainly associated with translation regulation and the cytoskeleton, long non-coding RNAs in P-body tend to interact with RNAs, whereas cytoplasmic genes are conserved and essential for fundamental processes, and cytoplasmic lncRNAs mostly interact with proteins. During hESC to mesodermal differentiation, both the number of P-bodies and enriched genes were significantly reduced. In addition, P-bodies selectively attracted specific transposable elements in hESCs. Perturbation of P-body gene expression or overexpression of P-body core protein LSM14A could disrupt hESC differentiation but not maintenance. In conclusion, our data elucidate the dynamics of P-body during the differentiation of hESCs to the mesodermal lineage and support the link between P-body and stem cell pluripotency.

Supports a between-group comparison across 34 samples.

How we read this: 16 replicated groups read from 34 sample titles; they account for 34 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
