TP53 promotes lineage commitment of human embryonic stem cells through ciliogenesis and sonic hedgehog signaling [ChIP-seq]

Project description:NGS was used to analyze role of TP53 in differentiation of human embryonic stem cells. TP53, a transcription factor, binds DNA and regulates transcription of specific genes. Chipseq of TP53 was done on WT ESCs and NPCs to identify direct targets of TP53 during differentiation of hESCs into neuronal lineage.

TP53 promotes lineage commitment of human embryonic stem cells through ciliogenesis and sonic hedgehog signaling [RNA-Seq]

Project description:H9 WT ESCs or TP53 KO (Clone 1) ESCs were injected subcutaneously into mice for teratoma formation. 6-8 weeks later, teratomas were isolated and total RNA was purified. TruSeq library preparation kit from Illumina was used to make libraries for RNA-Seq. NGS sequencing on Illumina NextSeq 500 was performed and data was analyzed to determine changes in transcriptome between WT and TP53 KO teratoma cells.

TP53 promotes lineage commitment of human embryonic stem cells through ciliogenesis and sonic hedgehog signaling.

Project description:Aneuploidy, defective differentiation, and inactivation of the tumor suppressor TP53 all occur frequently during tumorigenesis. Here, we probe the potential links among these cancer traits by inactivating TP53 in human embryonic stem cells (hESCs). TP53-/- hESCs exhibit increased proliferation rates, mitotic errors, and low-grade structural aneuploidy; produce poorly differentiated immature teratomas in mice; and fail to differentiate into neural progenitor cells (NPCs) in vitro. Genome-wide CRISPR screen reveals requirements of ciliogenesis and sonic hedgehog (Shh) pathways for hESC differentiation into NPCs. TP53 deletion causes abnormal ciliogenesis in neural rosettes. In addition to restraining cell proliferation through CDKN1A, TP53 activates the transcription of BBS9, which encodes a ciliogenesis regulator required for proper Shh signaling and NPC formation. This developmentally regulated transcriptional program of TP53 promotes ciliogenesis, restrains Shh signaling, and commits hESCs to neural lineages.

Sonic Hedgehog inhibitor cyclopamine effect on JAR cells

Project description:Physiologically, trophoblast progenitor cells differentiate into placental villous cytotrophoblast cells (CTBs). CTBs either differentiate into invasive lineage to yields extravillous cytotrophoblast cells (EVTs), or undergo cell fusion lineage to yields syncytiotrophoblast cells (STBs)，Sonic hedgehog (Shh) together with indian hedgehog (Ihh) and desert hedgehog (Dhh) consist of ligand of hedgehog signaling pathway, which plays pivotal roles in regulating cell proliferation, cell differentiation, organogenesis and development, even involving in tumorigenesis and progression. previous study had summarized and indicatedthat hedgehog proteins played important roles in regulating hematopoiesis, vasculogenesis and angiogenesis during embryogenesis and development. Herein, we investigate the effect of the Sonic Hedgehog morphogen inhibitor Cyclopamine on JAR cells
