USP7 controls the oncogenic transcriptional circuitry and is a novel therapeutic target in T cell leukemia

ABSTRACT: T-cell acute lymphoblastic leukemia (T-ALL) is an immature hematopoietic malignancy driven mainly by oncogenic activation of NOTCH1 signaling. In this study we chemically inhibited the deubiquinating enzyme USP7 and assayed for gene expression changes. This piece of data was further integrated to epigenetic changes using ChIP-Sequencing analysis of H3K27me3, H2AUb, H2BUb, H3K27Ac and H3K79me2 upon inhibition of USP7. These results coupled helped to determine the role of USP7 in stabilizing and promoting T-ALL leukemia. We also compared the gene expression and epigenetic changes of USP7 inhibition with inhibition of NOTCH1 pathway and JMJD3.

The USP7-TRIM27 axis as part of non-canonical PRC1.1 is a druggable target in leukemia

Project description:In an attempt to unravel the functionality and targettability of the non-canonical PRC1.1 Polycomb complex in human leukemogenesis, we dissected the subunit composition of the PRC1.1 complex and show that USP7 and TRIM27 are integral components. USP7 interactome analyses show that PRC1.1 is the predominant Polycomb complex co-precipitating with USP7. USP7 inhibition results in PRC1.1 disassembly and loss of chromatin binding, coinciding with reduced H2AK119ub and H3K27ac levels and diminished gene transcription of active PRC1.1-controlled loci, whereas H3K4me3 levels remain unaffected. TRIM27 and USP7 are reciprocally required for incorporation into PRC1.1, and TRIM27 knockdown partially rescues USP7 inhibitor sensitivity. USP7 inhibitors effectively impair proliferation in (primary) AML cells in vitro, also independent of the USP7-MDM2-TP53 axis, and MLL-AF9-induced leukemia is significantly delayed in vivo in human leukemia xenografts. We propose a model where USP7 counteracts TRIM27 E3 ligase activity, thereby maintaining PRC1.1 integrity and function. Moreover, USP7 inhibition may be a promising new strategy to treat AML patients.

Proteasome Inhibition Targets the KMT2A Transcriptional Complex

Project description:We quantitatively evaluated H2Bub and H3K79me2 epigenetic marks genome wide in a KMT2A rearranged B lineage acute lymphoblastic leukemia cell line after treatment with bortezomib over a 6 hour time course by ChIP-Rx. We identified rapid and concordant depletion of these epigenetic marks within two hours. To look at gene expression changes, RNA sequencing was performed on KMT2A rearranged B lineage acute lymphoblastic leukemia patient samples in the presence and absence of bortezomib exposure.

YG001: A Usp7-Tip60 pathway regulates early adipogenesis

Project description:USP7, a dominant DUB activity in 3T3-L1 adipocytes and in mouse adipose tissue, increases Tip60 protein levels, and deubiquitinates Tip60 both in intact cells and in vitro. Treatment with a pan deubiquitinase (DUB) inhibitor, or knockdown of USP7, decreases adipogenesis. Transcriptome analysis reveals a common set of cell cycle genes to be co-regulated by both Tip60 and USP7. Knock down of either factor results in impaired mitotic clonal expansion, an early step in adipogenesis. These results therefore reveal deubiquitination of a transcriptional coregulator to be a key mechanism in the regulation of early adipogenesis Mature 3T3-L1 adipocytes were subjected to RNAi-mediated knock down with control(C), USP7(U)- or Tip60(T)-specific oligonucleotides. For this, 4 replicates of differentiated 3T3-L1 cells were transfected with Amaxa technology. Two days after transfection cells were washed twice with PBS twice and lysed in 0.5ml Trizol (Invitrogen). mRNA expression of Tip60 and USP7 was assessed by qRT-PCR. Amplified cRNA samples were labeled with either cy3 or cy5 and put on microarray together with and oppositely labeled common reference sample consisting of cRNA derived from undifferentiated 3T3-L1 cells.

USP7 counteracts the activation of the mitotic program

Project description:Chemical inhibitors of the deubiquitinase USP7 are currently being developed as anticancer agents, due to their capacity to activate P53. Regardless of this activity, USP7 inhibitors also generate DNA damage in a p53-independent manner. However, the mechanism of this genotoxicity remains unknown. Surprisingly, even if USP7 inhibitors stop DNA replication, this occurs concomitant to a premature activation of mitotic kinases such as CDK1, which impairs chromosome segregation and is toxic for mammalian cells. Mechanistically, we show that USP7 interacts with the phosphatase PP2A and regulates its function. Accordingly, USP7 or PP2A inhibition trigger similar changes on the phosphoproteome, with a particular bias towards mitotic targets. Supporting our model, the toxicity of USP7 inhibitors is alleviated by lowering CDK1 activity or by the chemical activation of PP2A. Our work sheds light into the mechanism of action of USP7 inhibitors and provides the first example of triggering premature mitotic entry through perturbation of ubiquitin signaling.

Characterizing the contrasting roles of JMJD3 and UTX histone demethylases in T cell acute lymphoblastic leukemia [JMJD3_CUTLL1_ChIP-seq]

Project description:T-cell acute lymphoblastic leukemia (T-ALL) is an immature hematopoietic malignancy driven mainly by oncogenic activation of NOTCH1 signaling. In this study we assayed for genome-wide localization of JMJD3 enrichment. This piece of data was further integrated to expression changes using RNA sequencing as well as ChIP-Sequencing analysis of H3K27me3 upon genomic/genetic knock-down or chemical inhibition of JMJD3 and UTX. These results, coupled to genomic analysis of primary samples for the genomic status of the UTX gene in T-ALL, helped us to identify a hitherto unknown role of JMJD3 as an oncogenice facilitator in leukemia whereas UTX plays a tumor suppressor role.
