TranscriptomicsNOTCH1 activation in breast cancer confers sensitivity to inhibition of SUMOylation
Breast cancer is genetically heterogeneous, and recent studies have underlined a prominent contribution of epigenetics to the development of this disease. To uncover new synthetic lethalities with known breast cancer oncogenes, we screened an epigenome-focused short hairpin RNA library on a panel...

ProteomicsUncovering Global SUMOylation Signaling Networks in a Site-Specific Manner
SUMOylation is a reversible post-translational modification essential for genome stability. Using high-resolution mass spectrometry, we have studied global SUMOylation in mammalian cells and in a site-specific manner, identifying a total of over 4,300 SUMOylation sites in over 1,600 proteins. Moreov...

TranscriptomicsGenome-wide analysis of androgen receptor (AR) SUMOylation effects on gene expression (HEK293).
Androgen receptor (AR) plays an important regulatory role during prostate cancer development. ARM-bM-^@M-^Ys transcriptional activity is regulated by androgenic ligands, but also by post-translational modifications. To study the role of the AR SUMOylation in genuine chromatin environment, we compare...

TranscriptomicsSumoylation at Chromatin Governs Coordinated Repression of a Transcriptionnal Program Essential for Cell Growth and Proliferation 3
mRNA profiling of WI38 expressing shCt or shUbc9 4 days post-infection. The goals of this study is to analyse transcriptionnal changes in cells were sumoylation pathway is inactivated and to compare them with ChIPseq data for several histones marks and proteins of the SUMO machinery.

ProteomicsIs transthyretin a regulator of Ubc9 SUMOylation?
Ageing and mutations of transthyretin (TTR), the thyroid hormones and retinol transporting protein lead to amyloidosis by destabilizing the structure of TTR. Because protein structure is regulated through posttranslational modifications, we investigated the Small Ubiquitin-like Modifier (SUMO)ylatio...

TranscriptomicsDisrupting SUMOylation potentiates transactivation function and ameliorates polyglutamine AR-mediated disease
Our findings demonstrate beneficial effects of enhancing transactivation function of the ligand-activated polyQ AR and indicate that the SUMOylation pathway may provide new targets for therapeutic intervention. We mutated conserved lysines in the polyQ AR that are targeted by SUMO, a modification th...

TranscriptomicsA sumoylation-dependent transcriptional subprogram is required for Myc-driven tumorigenesis
Myc is an oncogenic transcription factor frequently dysregulated in human cancer. To identify pathways supporting the Myc oncogenic program, we employed a genome-wide RNAi screen for Myc-synthetic-lethal (MySL) genes and uncovered a role for the SUMO-activating-enzyme (SAE1/2). Loss of SAE1/2 enzyma...
