Whole heart transcriptional response to complete and epiblast-specfic deletion of Zic3 in 15.5 dpc mouse embryos

ABSTRACT: In order to better understand the molecular basis for the heart defects seen in Zic3 null and epiblast CKO embryos, we investigated whether complete or epiblast-specific deletion of Zic3 would impact later embryonic heart development at the transcriptional level by whole genome expression microarray.

Whole heart transcriptional response to complete and epiblast-specfic deletion of Zic3 in 15.5 dpc mouse embryos

Project description:In order to better understand the molecular basis for the heart defects seen in Zic3 null and epiblast CKO embryos, we investigated whether complete or epiblast-specific deletion of Zic3 would impact later embryonic heart development at the transcriptional level by whole genome expression microarray. The whole heart was carefully dissected out from 15.5 dpc Zic3 +/y, Zic3 flox/y, Zic3 flox/y; Sox2-cre, and Zic3 -/y embryos, total RNAs were extracted and purified using RNeasy Mini Kit (QIAGEN). Spectrophotometry (NanoDrop-1000 Spectrophotometer, Thermo Fisher Scientific) and microfluidic electrophoresis (Experion Automated Electrophoresis System, Bio-Rad Laboratories) were used for RNA quality control. In vitro transcription was performed using Illumina TotalPrep RNA Amplification Kit (Applied Biosystems/Ambion). cRNAs were hybridized onto Illumina MouseWG-6 v2.0 Expression BeadChips (Illumina) per manufacturer’s instructions.

ChIP-seq of Zic3 in ES-E14Tg2a embryonic stem cells after 2 days of differentiation to epiblast-like cells

Project description:Identification of Zic3 cistrome at ESC, d1EpiLC and d2EpiLC. ChIPmentaion experiments were performed using ZIC3 (Abcam, ab222124) antibody in the Rex1GFPd2 mouse embryonic stem cell line (ESC; parental line; E14Tg2a) and d1- and d2-EpiLC differentiated states.

RNA-seq of E14Tg2a cells upon Zic3 knockdown after day1 and day2 of differentiation into epiblast-like stem cells

Project description:Identification of Zic3-dependent transcriptome at d1EpiLC and d2EpiLC. Gene expression was studied in the presence or absence of Zic3 (RNAi) in the Rex1GFPd2 mouse embryonic stem cell line (parental line; E14Tg2a) in d1- and d2-EpiLC differentiated states.

ZIC2 and ZIC3 promote SWI/SNF recruitment to safeguard progression towards human primed pluripotency [ChIP-seq]

Project description:The primed epiblast acts as a transitional stage between the relatively homogeneous naïve epiblast and the gastrulating embryo. Its formation entails coordinated changes in regulatory circuits driven by strict epigenetic mechanisms. Using a multi-omic approach in human embryonic stem cell models across the spectrum of peri-implantation development, we demonstrate that the transcription factors ZIC2 and ZIC3 have overlapping but essential roles in opening primed-specific enhancers. Together they are essential to facilitate progression to and maintain primed pluripotency. ZIC2/3 achieve their function by recruiting SWI/SNF to chromatin and loss of ZIC2/3 or degradation of SWI/SNF both prevent enhancer activation. Loss of ZIC2/3 results in transcriptome changes consistent with perturbed Polycomb activity and a shift towards the expression of genes linked to mesendoderm differentiation. Additionally, we find an intriguing dependency on the transcriptional machinery for sustained recruitment of ZIC2/3 over a subset of primed-hESC specific enhancers. Taken together, ZIC2 and ZIC3 regulate highly dynamic lineage-specific enhancers and collectively act as key regulators of human primed pluripotency.

Zic3 interacts with distant regulatory elements to regulate zebrafish developmental genes

Project description:Zic3 regulates early embryonic patterning in vertebrates. Its loss-of-function disrupts gastrulation, left-right patterning, and neurogenesis. We use the zebrafish as a model to study the developmental role of Zic3 in vivo. Using a combination of two genomics approaches – ChIP-seq and microarray, we identified Zic3 targets, which include genes from the Nodal and Wnt pathways, and show for the first time cis-regulation of these genes by Zic3 using in vivo enhancer assay. We uncovered a previously unrecognized link between Zic3 and the non-canonical Wnt pathway in gastrulation and left-right patterning, and identified neural pre-pattern genes as Zic3 targets during the early steps of neural induction. Zic3 preferably binds to distal intergenic regions, some of which contain evolutionarily conserved functional enhancers. Our study establishes the zebrafish as an excellent model for genome-wide study of a transcription factor in vivo.

Zic3 ChIP-on-chip in mouse ES cells

Project description:The transcription factor Zic3 is required for maintenance of embryonic stem (ES) cell pluripotency (Lim LS et al, Mol Biol Cell. 2007;18:1348-1358). By genome-wide chromatin immunoprecipitation (ChIP-chip) in ES cells, we have identified 379 direct Zic3 targets, many of which are functionally associated with pluripotency, cell cycle, proliferation, oncogenesis and early embryogenesis.

ZIC2 and ZIC3 promote SWI/SNF recruitment to safeguard progression towards human primed pluripotency [ATAC-Seq]

Project description:ZIC2 and ZIC3 are essential for acquisition and maintenance of primed pluripotency. In this study, we conducted ATAC-seq in single and compound knockout of ZIC2, ZIC3 and ZIC5 primed hESCs, naïve hESCs lacking ZIC3 that inducibly express ZIC2, naive hESCs that inducible express ZIC2 or ZIC3, ZIC3-depleted primed hESCs that were cultured in 5iLAF medium for six days and undergoing reversion to a naive state, naive hESCs expressing ectopic ZIC2 in the presence of a BRG1 PROTAC.

PLURIPOTENCY REGULATOR ZIC3 IS AN EARLY LINEAGE SPECIFIER

Project description:Sustained expression of the key pluripotency transcriptional regulators and proliferative factors is needed for the maintenance of embryonic stem cells and early progenitors of various lineages. Zic3 is one of those factors which has been shown to be important for embryonic stem cell pluripotency. Through combinatorial analysis of transcription factor binding sites and the corresponding gene-regulation, we show that Zic3 not only activates key pluripotency genes but also acts cooperatively with them in connecting important circuits of regulation in ES cell in proliferation and maintenance of early progenitors.
