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.

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.

Novel, Selective Inhibitors of USP7 Uncover Multiple Mechanisms of Antitumor Activity in Vitro and in Vivo

Project description:The human lung tumor cell line, NCI-H526, was treated with DMSO vehicle control or 0.5 µM of the novel small molecule USP7 inhibitor, USP7-797. At 24 and 48 hour time points, cells were harvested and used for RNA-Seq analysis. In order to identify pathways impacted by USP7 (Ubiquitin Specific Peptidase 7) inhibition, we used RNASeq to profile transcriptomic changes in human lung cancer NCI-H526 cells following treatment with the novel, selective USP7 inhibitor, USP7-797, or control DMSO for 24 or 48 hours. USP7 inhibitor treatment resulted in upregulation of a large number of genes normally silenced by the polycomb repressive complex 2 (PRC2). PRC2, whose components include the proteins EZH2, SUZ12 and EED, trimethylates histone H3 at lysine 27 (H3K27me3). Gene set enrichment analysis showed that the top 10 significantly enriched gene sets are all regulated by this pathway. RNA was extracted from approximately 1 million cells using the Allprep DNA/RNA Mini Kit (Qiagen). Whole transcriptome non-stranded libraries were prepared using the TruSeq RNA Library Prep Kit v2 (Illumina). Sequencing was performed on Illumina NovaSeq using paired-end mode, 200 cycles, targeting 40 million reads per sample.
