Effect of L-Proline on mouse embryonic stem cells (ESCs)

ABSTRACT: We found that the non-essential amino acid L-Proline (L-Pro) acts as a signaling molecule that promotes the conversion of embryonic stem cells (ESCs) into mesenchymal-like, spindle-shaped, highly motile, invasive pluripotent stem cells. This embryonic stem cell-to-mesenchymal-like transition (esMT) is accompanied by a genome-wide remodeling of the transcriptome We used microarrays to elucidate whether a diverse transcriptional program is the basis of the morphological and motility differences between ESCs and L- Proline treated ESCs (PiCs)

TET1 interactome by SILAC IP-MS in mouse ESCs

Project description:TET1 maintains hypomethylation at bivalent promoters through its catalytic activity in embryonic stem cells (ESCs). However, whether and how TET1 exerts catalytic activity-independent functions in regulating bivalent genes is not well understood. Therefore, we mapped the TET1 interactome in mouse ESCs using a SILAC IP-MS proteomics approach.

OCT4 IP-MS in Naive and Primed Human ESCs

Project description:Understanding the molecular underpinnings of pluripotency is a prerequisite for optimal maintenance and application of embryonic stem cells (ESCs). While the protein-protein interactions of core pluripotency factors have been identified in mouse ESCs, their interactome in human ESCs (hESCs) has not to date been explored. Here we mapped the OCT4 interactomes in naïve and primed hESCs, revealing extensive connections to mammalian ATP-dependent nucleosome remodeling complexes.

eIF4A3 interactome by IP-MS in mouse ESCs

Project description:RNA helicases are involved in multiple steps of RNA metabolism to direct their roles in gene expression, yet their functions in pluripotency control remain largely unexplored. Starting from an RNAi screen of RNA helicases, we identified that eIF4A3, a DEAD-box (Ddx) helicase component of the exon junction complex (EJC), is essential for the maintenance of embryonic stem cells (ESCs). We mapped the eIF4A3 interactomes in mouse ESCs, revealing that eIF4A3 is widely involved in the post-transcriptional regulation of gene expression. Mechanistically, we show that eIF4A3 post-transcriptionally controls the pluripotency-related cell cycle regulators and that its depletion causes cellular differentiation via cell cycle dysregulation. Specifically, eIF4A3 is required for the efficient nuclear export of Ccnb1 mRNA, which encodes Cyclin B1, a key component of the pluripotency-promoting pathway during cell cycle progression of ESCs. Our results reveal a previously unappreciated role of eIF4A3 and its associated EJC in the post-transcriptional cell cycle control in maintaining stem cell pluripotency.
