Transcriptomic changes in THP1 human AML cell line on PHF6 knockout, PHF6R274Q mutation, PHIP knockout, and double knockout of PHF6 and PHIP compared to wildtype cells

ABSTRACT: 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.
