Project description:PHF6 is a transcriptional regulator mutated in 3-5% of acute myeloid leukemia. To understand how PHF6 and its functional partner PHIP interact with each other on chromatin, we performed ChIP-Seq for PHF6 (in the presence and absence of PHIP), for PHF6R274Q mutant, and for PHIP. We observd that PHF6 and PHIP peaks overlap on chromatin, and PHF6 requires PHIP for its chromatin occupancy. ATAC-Seq and H3K27ac ChIP-Seq showed that PHF6 and PHIP occupy open and active regions of the genome.

Project description:PHF6 is a transcriptional regulator mutated in 3-5% of acute myeloid leukemia. To understand the effect of loss and clinical mutation of PHF6 on the transcriptome of myeloid cells, we generated multiple wildtype and PHF6 knockout clones, as well as clones expressing the most common clinical mutant of the protein-PHF6R274Q. We observed that both single and double knockouts and mutation of PHF6 shifted the cells towards stemness and away from differentiation. Additionally we identified PHIP as a possible functional partner for PHF6. To investigate their common biological function, we generated multiple single knockout clones of PHIP as well as double knockout clones of PHIP and PHF6, and observed that, similar to single knockout of PHF6, PHIP knockout and double knockout also shifted cells towards stemness and away from differentiation. Collectively, our experiments show that PHF6 and PHIP, separately identified as being mutated in AML, exert similar downstream effects on the AML transcriptome.
Project description:Expression data from untreated or Dll4-Fc treated THP1 cell line. We used Dll4-Fc stimulation of AML cells to study whether Notch activation has an impact on AML. We analyzed THP1 cell line in vitro treated with Dll4-Fc or vehicle control to determine genes affected by Notch activation.

We analyzed THP1 cell line in vitro treated with Dll4-Fc or vehicle control to determine genes affected by Notch activation. THP1 cell line was cultured on plate coated with 30 nM Dll4-Fc or vehicle for 48 hours prior to RNA extraction and hybridization to Human Genome U133 Plus 2.0 Affymetrix arrays.

Project description:CRISPR Cas9 guided knockout (KO) of PHF6 in human THP1 AML cell line. We performed bulk RNA-Seq on knockout (PHF6 KO) and wildtype (CTRL) clones derived from THP1 cells transduced with lentiviral vectors encoding Cas9 protein and either PHF6 gRNAs or non-targeting gRNAs. Our results reveal that PHF6 knockout upregulates self-renewal gene sets and downregulates myeloid differentiation gene sets.
