Transcriptomic changes in PHF6 knockout THP1 human AML cell line on rescue with PHF6 wildtype (with and without PHIP) or rescue with PHF6R274Q mutant

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.

Transcriptome changes caused by PHF6 knockout in THP1 human AML cell line

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.

Molecular and clinical analyses of PHF6 mutant myeloid neoplasia provide clues as to their pathogenesis and therapeutic targeting

Project description:PHF6 mutations (PHF6MT) are identified in various myeloid neoplasms (MN). However, little is known about the precise function and consequences of PHF6 in MN. Our comprehensive genomic analyses focused on three main findings. Firstly, we revealed a different pattern of genes correlating with PHF6MT in male and female cases. When analyzing male and female cases separately, in only male cases, RUNX1 and U2AF1 were co-mutated with PHF6. In contrast, female cases revealed co-occurrence of ASXL1 mutations and X-chromosome deletions with PHF6MT. Next, proteomics analysis revealed a direct interaction between PHF6 and the pioneer transcription factor RUNX1. Both proteins co-localize in active enhancer regions that define the context of lineage differentiation. Finally, we demonstrated a negative prognostic role of PHF6MT, especially in association with RUNX1. The negative effects on survival were additive as PHF6MT cases with RUNX1 mutations had worse outcomes when compared to cases carrying single mutation or wild-type.

PHF6 OCCUPANCYIN HUMAN T-CELL ACUTE LYMPHOBLASTIC LEUKEMIA

Project description:Here we identify the genome-wide occupancy of PHF6 in T-ALL cells. Human T-ALL cells were cross-linked with formaldehyde for 20 min. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. A sample of whole cell extract (WCE) was sequenced and used as the background to determine enrichment. ChIP was performed using an antibody against total PHF6 (Bethyl A301-451A). This represents the ChIP-seq portion of this dataset.

RNA sequencing of isogenic Phf6 wild type and Phf6 knockout mouse T-ALL cells

Project description:Loss-of-function mutations Phf6 occur frequently in both adult and pediatric T-cell Acute Lymphoblastic Leukemia (T-ALL). Although Phf6 is widely expressed, little is known about its proposed function as epigenetic regulator and tumor suppressor. To address the role of Phf6 in the leukemia development, here we analyze by RNAseq the gene expression profiles of isogenic Phf6 wild type and Phf6 knockout leukemia cells transformed by overexpression of an oncogenic mutant form of the NOTCH1 receptor.

Bone Marrow Mesenchymal Stromal Cells Support Translation in Refractory Acute Myeloid Leukemia

Project description:In acute myeloid leukemia (AML), malignant cells surviving chemotherapy rely on high mRNA translation and their microenvironmental metabolic support to drive relapse. However, the role of translational reprogramming in the niche is unclear. Here we found that relapsing AML cells increase translation in their bone marrow (BM) niches, where BM mesenchymal stromal cells (BMSCs) become a source of eIF4A-cap-dependent translation machinery that is transferred to AML cells via extracellular vesicles (EVs), to meet their translational demands. In two independent models of highly chemo-resistant AML driven by MLL-AF9 or FLT3-ITD;NPMc mutations, protein synthesis levels increase in refractory AML dependently on nestin+ BMSCs. Inhibiting cap-dependent translation in BMSCs abolishes their chemoprotective ability, while EVs from BMSCs carrying eIF4A boost AML cell translation and survival. Consequently, eIF4A inhibition synergizes with conventional chemotherapy. Together, these results suggest that AML cells rely on BMSCs to maintain an oncogenic translational program required for relapse
