Study 2- RNA-seq of male KOLF2.2J hiPSC-derived trophoblast cell lines homozygous null for seven different transcription factors

Project description:This study aims to phenotype iPSC-derived trophoblast lines that contain homozygous null alleles for transcription factors expressed within the extra-embryonic lineage, with a focus on differentiation toward either primitive syncytium or extra-embryonic mesenchymal cells, depending on the TF being analyzed. Null alleles were generated using three distinct genetic engineering approaches: full protein coding region deletion (KO), critical exon deletion (CE), and insertion of a premature termination codon with frameshift (PTC+1). RNA-seq data was generated after 6 days of initiating differentiation from iPSCs. The study included the homozygous null alleles for the following transcription factors: MEIS1, MXD1, MEIS2, RUNX1, MEF2C, NCOA3, and BHLHE40. This analysis provided insight into the differences between the various CRISPR-Cas9-based approaches and the impact of loss of function for these transcription factors in trophoblast lineage differentiation.

RNA-seq data was generated after 6 days of initiating differentiation from iPSCs. The study included the homozygous null alleles for the following transcription factors: GRHL1, POU2F3, EPAS1, FOSB, GCM1, PPARG, and ISL1. Notably, the hypoxia-inducible factor EPAS1 was evaluated under both 20% oxygen and 3% (~ level present at peri-implantation) oxygen concentrations. This analysis provided insight into the differences between the various CRISPR-Cas9-based approaches and the impact of loss of function for these transcription factors in trophoblast lineage differentiation.

Study 3- RNA-seq of male KOLF2.2J hiPSC-derived cortical brain organoids homozygous null for six different transcription factors

Project description:This study aims to phenotype iPSC-derived cortical brain organoids that contain homozygous null alleles for transcription factors expressed in the early neuroectoderm. Null alleles were generated using three distinct genetic engineering approaches: full coding region deletion (KO), critical exon deletion (CE), and insertion of a premature termination codon with frameshift (PTC+1). RNA-seq data was generated at the indicated day post initiation of differentiation from hiPSCs. The study included the homozygous null alleles for the following transcription factors: LHX9, RFX4, PAX6, OTX1, LHX5, and FEZF2. This analysis provided insight into the differences between the various CRISPR-Cas9-based approaches and the impact of loss of function for these transcription factors in cortical brain organoid differentiation.

Study 6- RNA-seq of female WIBJ2 hiPSC-derived cortical brain organoids and extra-embryonic lineages homozygous null for five different transcription factors

Project description:This study aimed to phenotype iPSC-derived cortical brain organoids that contain homozygous null alleles for transcription factor PAX6 and to phenotype iPSC-derived extra-embryonic cell lineages that contain homozygous null alleles for transcription factors PPARG, EPAS1, GCM1, and GRHL1. Null alleles were generated by the insertion of a premature termination codon with frameshift (PTC+1). This analysis provided insight into the impact of loss of function for these transcription factors in the respective cell lineages.

Study 7- RNA-seq of male KOLF2.2J hiPSC-derived differentiated cells for lines in which the original mutation to create null alleles was reverted back to wildtype

Project description:This study aimed to phenotype iPSC-derived cortical brain organoids that contained corrections (reversions to wt) for homozygous null alleles for transcription factor PAX6 and to phenotype iPSC-derived extra-embryonic cell lineages that had contained homozygous null alleles for transcription factors PPARG, EPAS1, GCM1, and GRHL1. The original homozygous mutant lines were created by introducing a premature termination codon and frameshift (PTC+1) approach. Here in these clones, these mutations were reverted back to wt and restored gene function. The homozygous null alleles for the five genes studied here showed pronounced transcriptomic changes compared to the parental line, the data provided here indicate, upon reversion of the PTC+1 mutations back to wt, the normal wt transcriptomic response was largely restored indicating specificity of the engineered alleles in manipulating the respective gene’s function.
