GATA6-AS1 Regulates GATA6 Expression to Modulate Human Endoderm Differentiation

Project description:Transcriptome analysis has uncovered a series of long noncoding RNAs (lncRNAs) transcribed during cell differentiation. Here, we uncovered lncRNA GATA6-AS1 is a functional lncRNA in definitive endoderm (DE) differentiation. We found GATA6-AS1 positively regulated the expression of endoderm key factor GATA6, which was different from previous reports in other biological contexts. Further investigation showed GATA6-AS1 interacted with SMAD2/3 and recruited SMAD2/3 to the promoter region of the GATA6 gene locus. In addition, overexpression of GATA6 was able to rescue the defect of DE differentiation due to the absence of GATA6-AS1, suggesting GATA6 was the functional target of GATA6-AS1 during endoderm differentiation. Ultimately, our study uncovers GATA6-AS1 is necessary for DE and pancreas differentiation, and reveals the detailed regulation mechanism between GATA6-AS1 and DE differentiation.

GATA6 defines endoderm fate by controlling chromatin accessibility during differentiation of human induced pluripotent stem cells [ATAC-seq]

Project description:Investigation of the role played by GATA6 in establishing the definitive endoderm chromatin accessbility profile. We used pluripotent stem cells as a model of early development. We derived GATA6-/- pluripotent cells with an inducible GATA6 construct that permits exongenous GATA6 cDNA expression upon supplmentation of doxycycline. We differentiated GATA6 +/+ and GATA6-/- (with and without doxycyline) cells to definitive endoderm and analyzed the chromatin profile using ATAC-seq.

GATA6 defines endoderm fate by controlling chromatin accessibility during differentiation of human induced pluripotent stem cells [TF_ChIP-seq]

Project description:Investigation of the role played by GATA6 in establishing the definitive endoderm chromatin accessbility profile. We used pluripotent stem cells as a model of early development. We derived GATA6-/- pluripotent cells with an inducible GATA6 or FOXA2 construct that permits exongenous GATA6 or FOXA2 cDNA expression upon supplementation of doxycycline. We differentiated GATA6+/+ and GATA6-/- (with and without doxycyline) cells to definitive endoderm and analyzed transcription factor binding profiles using CHIP-seq.

Gene Expression Changes in Definitive Endoderm in response to FGF Signaling

Project description:FGF Signaling is required for hepatic progenitor cell formation from endoderm. The mechanism of this process is poorly understood We used microarrays to identify genes directly regulated by FGF signaling in definitive endoderm that may be involved in hepatic specification.

ALKBH5 modulates endoderm fate diversion from hESCs through the ALKBH5-GATA6-WNT/β-catenin regulatory axis [meRIP-seq]

Project description:N6-methyladenonsine (m6A) modification locates ubiquitously in mammalian mRNA, and profoundly impacts various physiological processes and pathogenesis. However, the precise involvement of m6A in early endoderm development has yet to be fully elucidated. Here, we reported that depletion of the m6A demethylase ALKBH5 in human embryonic stem cells (hESCs) severely impaired definitive endoderm (DE) differentiation. Within this process, ALKBH5-/- hESCs failed to undergo the primitive streak (PS) intermediate transition, which is considered as a prelude to endoderm specification. Mechanistically, we demonstrated that ALKBH5 deficiency induced m6A hypermethylation around the 3’ untranslated region (3’UTR) of GATA6 transcripts and destabilized GATA6 mRNA in a YTHDF2-dependent manner. Moreover, dysregulation of GATA6 expression ablated its occupancy with critical regulators of Wnt/β-catenin signaling pathway, thereby disrupting the signaling logic underlying DE formation. Overall, our findings unveil a mechanism whereby the ALKBH5-GATA6-WNT/β-catenin axis modulates human in vitro DE induction, and present novel insights on m6A modification in early embryonic development.
