Genome-wide analysis of gene expression in LIF and LIF plus CHIR99021 in C57BL/6 mouse embryonic stem cells(B6 mESCs)

ABSTRACT: Analysis of genes induced by CHIR99021 CHIR99021 is a inhibitor of glycogen synthase kinase 3 (GSK3) and can promote B6 mESC sef-renewal when combined with LIF in serum condition. Total RNA obtained from B6 mESCs treated with LIF or LIF/CHIR99021 for 12 hours.

Identifying CHIR99021 and AICAR-regulated genes in the J1 mESCs

Project description:It has been demonstrated that CHIR99021 promotes self-renewal of mouse embryonic stem cells, however, the target genes of CHIR99021 is not fully understood. AICAR is the activator of AMP-activated protein kinase. It is reported that AICAR plays important role in mouse embryonic stem cells, however the moleculor mechanism of this phenomenon is unknown. To better understand the downstream target genes of CHIR99021 and AICAR, we performed Microarray analyses to identify their downstream targets. The data show the genes regulated by CHIR99021 or AICAR. J1 mESCs maintained in medium containing 1000 U/mL LIF and supplemented without or with CHIR99021 or AICAR for 24 hours, then total RNA was extracted for analysis.

RNA-Seq of Diversity Outbred mouse embryonic stem cells

Project description:We measured genome-wide gene expression of embryonic stem cells derived from Diversity Outbred mice. We cultured cells in media with LIF + GSK3-beta inhibitor CHIR99021. All lines were passage 3-8 when RNA was collected. We obtained RNA-Seq from technical replicate cultures for three cell lines.

RNA-Seq of mouse embryonic stem cells derived from genetically diverse inbred mouse strains with varying alleles at Lifr gene

Project description:We measured genome-wide gene expression of embryonic stem cells derived from two different inbred mouse genetic backgrounds. For each genetic background we also conducted an allele swap at SNP rs50454566 upstream of the Lifr gene. We profiled cells from each of the four strains in triplicate (technical replicates). We cultured cells in media with LIF + GSK3-beta inhibitor CHIR99021. Cells remained unfed until harvest, six days later.

Transcriptional profiling by array of Klf2 wild-type and Klf2-Null mESCs cultured under 2i

Project description:The self-renewing pluripotent state was first captured in mouse embryonic stem cells (mESCs) over two decades ago. The standard condition requires the presence of serum and LIF, which provide growth promoting signals for cell expansion. However, there are pro-differentiation signals which destabilize the undifferentiated state of mESCs. The dual inhibition (2i) of the pro-differentiation Mek/Erk and Gsk3/Tcf3 pathways in mESCs is sufficient to establish an enhanced pluripotent “ground state” which bears features resembling the pre-implantation mouse epiblast. Gsk3 inhibition alleviates the repression of Esrrb, a transcription factor that can substitute for Nanog function in mESCs. The molecular mechanism that is mediated by Mek inhibition is however not clear. In this study, we investigate the pathway through which Mek inhibition operates to maintain ground state pluripotency. We have found that in mESCs, Kruppel-like factor 2 (Klf2) is a protein target of the Mek/Erk pathway; and that Klf2 protein is phosphorylated by Erk2 and subsequently degraded through the proteosome. It is therefore by Mek-inhibition through PD0325901 or 2i that enables the stabilization and accumulation of Klf2 to sustain ground state pluripotency. Importantly, we found that Klf2-null mESCs, while viable under LIF/Serum conditions, cannot be maintained and eventually gradually die within a few passages. Our result thus demonstrates that Klf2 is an essential factor of ground state pluripotency. Collectively, our study defines the Mek/Klf2 axis that cooperates with the Gsk3/Esrrb pathway in mediating ground state pluripotency.

Human cortical organoids. Chronic treatment with GSK3 inhibitor CHIR99021. Bulk RNAseq.

Project description:Here we used human cortical brain organoids to probe the longitudinal impact of GSK3 inhibition through multiple developmental stages. Chronic GSK3 inhibition increased the proliferation of neural progenitors and caused massive derangement of cortical tissue architecture. Cortical organoids were differentiated as previously described (Paşca et al., 2015, doi: 10.1038/nmeth.3415.).Chronic GSK3 inhibition was performed by adding CHIR99021 (Merck SML1046) to the medium at day 0 (1 microM) and kept throughout the differentiation process until reaching the respective collection timepoints (day 18, day 50, day 100).
