Project description:Here, we performed RNA-interactome capture (RIC) on nuclear fractions from human embryonic stem cells (hESCs). The poly(A)+ RNA-bound proteome was determined by UV light-mediated cross-linking (CL) of RNAs to proteins in living cells, followed by nuclei isolation, oligo(dT) purification of poly(A)-RNA-protein complexes, and mass spectrometry analysis of captured proteins. As a control, we applied a similar strategy to non-cross-linked (non-CL) samples. RIC was performed in four independent biological replicates. This data accompanies the manuscript: "Uncovering the RNA-binding protein landscape in the pluripotency network of human embryonic stem cells". Abstract: "Embryonic stem cell (ESC) self-renewal and cell-fate decisions are driven by a broad array of molecular signals. While transcriptional regulators have been extensively studied in human ESCs (hESCs), the extent to which RNA-binding proteins (RBPs) contribute to human pluripotency remains unclear. Here, we carry out a proteome-wide screen and identify 810 proteins that directly bind RNA in hESCs. We reveal that RBPs are preferentially expressed in hESCs and dynamically regulated during exit from pluripotency and early lineage specification. Moreover, we show that nearly 200 RBPs are affected by knockdown of OCT4, a master regulator of pluripotency, several dozen of which are directly bound by this factor. Intriguingly, over 20 percent of the proteins detected in our study are putative DNA- and RNA-binding proteins (DRBPs), among them key transcription factors (TFs). Using fluorescently labeled RNA and seCLIP (single-end enhanced crosslinking and immunoprecipitation) experiments, we discover that the pluripotency-associated STAT3 and OCT4 TFs interact with RNA in hESCs and confirm the direct binding of STAT3 to the conserved NORAD long-noncoding RNA. Taken together, our findings indicate that RBPs have a more widespread role in human pluripotency than previously appreciated, reinforcing the importance of post-transcriptional regulation in stem cell biology".

Project description:Embryonic stem cell (ESC) self-renewal and cell-fate decisions are driven by a broad array of molecular signals. While transcriptional regulators have been extensively studied in human ESCs (hESCs), the extent to which RNA-binding proteins (RBPs) contribute to human pluripotency remains unclear. Here, we carried out a proteome-wide screen and identified 810 proteins that directly bind RNA in hESCs. We determined the RBP catalog by using RNA-interactome capture (RIC), a method based on UV light-mediated cross-linking (CL) of RNAs to proteins in living cells, followed by oligo(dT) purification of poly(A)-RNA-protein complexes and mass spectrometry analysis of captured proteins. As control, we applied a similar strategy to non-cross-linked (non-CL) samples. To uncover the identity of the eluted proteins, we performed in-solution tryptic digestion of CL and non-CL eluates and analyzed their contents by a high-resolution mass spectrometer (Q-Exactive Plus). We then performed differential proteome analysis between CL and non-CL eluates, resulting in a set of 810 high-confidence protein groups, defined as the hESC RNA-interactome. RIC was carried out in four independent biological replicates. This data accompanies the manuscript: "Uncovering the RNA-binding protein landscape in the pluripotency network of human embryonic stem cells".

Project description:Genomic instability is the main cause of abnormal embryo development and abortion. NLRP7 dysfunctions affect embryonic development and lead to Hydatidiform Moles, but the underlying mechanisms remain largely elusive. Here, we show that NLRP7 knockout affects the genetic stability, resulting in increased DNA damage in both human embryonic stem cells and blastoids, making embryonic cells in blastoids more susceptible to apoptosis. Mechanistically, NLRP7 can interact with factors related to alternative splicing and DNA damage response, including DDX39B, PRPF8, THRAP3 and PARP1. Moreover, NLRP7 dysfunction leads to abnormal AS of genes involved in Homologous recombination in human embryonic stem cells, Such as Brca1 and Rad51. These results indicate that NLRP7-mediated Alternative splicing is potentially required for the maintenance of genome integrity during early human embryogenesis. Together, this study uncovers that NLRP7 plays an essential role in the maintenance of genetic stability during early human embryonic development by regulating alternative splicing of Homologous Recombination-related genes.

Project description:RNA-binding proteins (RBPs) have essential roles in RNA-mediated gene regulation, and yet annotation of RBPs is limited mainly to those with known RNA-binding domains. To systematically identify the RBPs of embryonic stem cells (ESCs), we here employ interactome capture, which combines UV cross-linking of RBP to RNA in living cells, oligo(dT) capture and MS. From mouse ESCs (mESCs), we have defined 555 proteins constituting the mESC mRNA interactome, including 283 proteins not previously annotated as RBPs. Of these, 68 new RBP candidates are highly expressed in ESCs compared to differentiated cells, implicating a role in stem-cell physiology. Two well-known E3 ubiquitin ligases, Trim25 (also called Efp) and Trim71 (also called Lin41), are validated as RBPs, revealing a potential link between RNA biology and protein-modification pathways. Our study confirms and expands the atlas of RBPs, providing a useful resource for the study of the RNA-RBP network in stem cells.
