Recruitment of TRIM33 to cell-context specific PML nuclear bodies regulates Nodal signaling in mESCs

Project description:TRIM33 is a chromatin reader required for mesendoderm differentiation upon activation of Nodal signaling. But, its role in mESCs is still elusive. Here, we found that TRIM33 co-localizes with promyelocytic leukemia nuclear bodies (PML NBs) specifically in mESCs to mediate Nodal signaling-directed transcription of Lefty1/2. We showed that TRIM33 puncta formation in mESCs depends on PML and specific assembly of PML NBs. Moreover, TRIM33 and PML co-regulate Lefty1/2 expression in mESCs. In addition, both PML and mESCs-specific PML NBs are required for TRIM33 recruitment at Lefty1/2 loci. Remarkably, PML NBs directly associate with the Lefty1/2 loci in mESCs. Finally, a TurboID proximity labeling experiment confirmed that TRIM33 is highly enriched in the mESCs-specific PML NBs. Thus, our study provides the mechanistic insight about TRIM33 condensate in regulating Nodal signaling-directed transcription in mESCs, it also reveals that PML NBs recruit distinct sets of client proteins in cell context dependent manner.

PML nuclear bodies form a regulatory hub via liquid-liquid phase separation for TRIM33 control of Lefty1/2 genes in mouse embryonic stem cells [RNA-seq]

Project description:TRIM33 is a chromatin reader required for nodal signaling during mesendoderm differentiation, although differences in its function between mouse embryonic stem cells (mESCs) and differentiated mesendoderm cells are unknown. Here, we found that TRIM33 co-condenses with PML nuclear bodies (NBs) via liquid-liquid phase separation specifically in mESCs to mediate nodal signaling-directed transcription of Lefty1/2. Our findings show that TRIM33 puncta formation depends on the presence of PML NBs. TurboID proximity labeling further revealed that PML NBs recruit distinct sets of client proteins in NaAsO2-treated, untreated mESCs, and differentiated cells. TRIM33 and PML co-regulate Lefty1/2 expression, while PML NBs directly associate with the Lefty1/2 loci and regulate a gene cluster that includes Lefty1/2 loci specifically in mESCs. Moreover, TRIM33 association with chromatin depends on PML NBs. Thus, PML NBs serve as a hub for transcriptional regulation of Lefty1/2 by TRIM33 and other pluripotency factors in mESCs.

Recruitment of TRIM33 to cell-context specific PML nuclear bodies regulates nodal signaling in mESCs.

Project description:TRIM33 is a chromatin reader required for mammalian mesendoderm differentiation after activation of Nodal signaling, while its role in mESCs is still elusive. Here, we report that TRIM33 co-localizes with promyelocytic leukemia nuclear bodies (PML-NBs) specifically in mESCs, to mediate Nodal signaling-directed transcription of Lefty1/2. We show that TRIM33 puncta formation in mESCs depends on PML and on specific assembly of PML-NBs. Moreover, TRIM33 and PML co-regulate Lefty1/2 expression in mESCs, with both PML protein and formation of mESCs-specific PML-NBs being required for TRIM33 recruitment to these loci, and PML-NBs directly associating with the Lefty1/2 loci. Finally, a TurboID proximity-labeling experiment confirmed that TRIM33 is highly enriched only in mESCs-specific PML-NBs. Thus, our study supports a model in which TRIM33 condensates regulate Nodal signaling-directed transcription in mESCs and shows that PML-NBs can recruit distinct sets of client proteins in a cell-context-dependent manner.

Nodal signaling maintains H3K18ac landscape to promote mesendodermal differentiation through TRIM33

Project description:The epigenome of a cell is established and maintained by chromatin modifiers and remodelers, which are recruited to the chromatin by specific transcription factors. In this report, we show that nodal cross-talks with the epigenome through TRIM33-H3K18ac to mediate mesendodermal genes expression. The chromatin accessibility at mesendodermal genes depends on TRIM33. Moreover, histone acetylation is essential for TRIM33 recruitment to many nodal target genes involved in mesendodermal differentiation. The distribution pattern of the H3K18ac mark changes from foci to expanded domains at the mesendodermal genes promoter during embryonic stem cells (ESCs) differentiation to embryoid bodies (EBs). This could be the cue to facilitate TRIM33 colocalized with Smad2/3 at chromatin in EBs but not in ESCs. TRIM33 interacts with the H3K18ac “writer” p300 dependent on nodal signaling, providing a positive feedback to promote activation of mesendodermal genes and association with HDAC1 plays a negative role in activation of mesendodermal genes.

Smad4 and Trim33 dependend nodal/activin responsive genes in differentiated mouse ESCs

Project description:In differentiated mouse ESCs, most of the nodal/activin responsive genes are dependent on both Smad4 and Trim33, some are solely dependent on Smad4, and some are dependent on Trim33. Ebs at Day2.5 from WT, Smad4 null, and Trim33 knock-down ESCs, were treated with activin or SB 431542 for 2 h.
