LC-MS/MS analyses of human PDAC cell lines after treatment with a new SUMO inhibitor

ABSTRACT: Pancreatic ductal adenocarcinoma (PDAC) still carries a dismal prognosis with overall five-year survival of 8%. Conventional combination chemotherapies are a clear advance in the treatment of PDAC, however subtypes of the disease exist, which exhibit extensive resistance to such therapies. Genomic MYC amplifications represent a distinct subset of PDAC with an aggressive tumor biology. It is clear that hyperactivation of MYC generates dependencies that can be exploited therapeutically. To find MYC-associated dependencies we analyzed human PDAC expression datasets. We observed that MYC is connected to the SUMOylation machinery in PDAC. Components of the SUMO pathway mark a PDAC subtype with worse prognosis and we provide evidence that hyperactivation of MYC is connected to an increased sensitivity to a novel SUMO inhibitor with a potential for further clinical development.

The SUMO Pathway as a Therapeutic Option in Pancreatic Cancer

A sumoylation-dependent transcriptional subprogram is required for Myc-driven tumorigenesis

Project description: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 enzymatic activity drives synthetic lethality with Myc. Mechanistically, SAE2 inhibition switches a transcriptional subprogram of Myc from activated to repressed. A subset of these SUMOylation-dependent Myc-switchers (SMS genes) governs mitotic spindle function and is required to support the Myc oncogenic program. comparison of 4 treatments: normal HMEC, High Myc in HMEC, SUMO depleted in HMEC, High Myc+Sumo Depleted in HMEC

Oncogenic MYC induces a dependency on the spliceosome in human cancer

Project description:c-MYC (MYC) overexpression or hyperactivation is one of the most common drivers of human cancer. Despite intensive study, the MYC oncogene remains recalcitrant to therapeutic inhibition. Like other classic oncogenes, hyperactivation of MYC leads to collateral stresses onto cancer cells, suggesting that tumors harbor unique vulnerabilities arising from oncogenic activation of MYC. Herein, we discover the spliceosome as a new target of oncogenic stress in MYC-driven cancers. We identify BUD31 as a MYC-synthetic lethal gene, and demonstrate that BUD31 is a splicing factor required for the assembly and catalytic activity of the spliceosome. Core spliceosomal factors (SF3B1, U2AF1, and others) associate with BUD31 and are also required to tolerate oncogenic MYC. Notably, MYC hyperactivation induces an increase in total pre-mRNA synthesis, suggesting an increased burden on the core spliceosome to process pre-mRNA. In contrast to normal cells, partial inhibition of the spliceosome in MYC-hyperactivated cells leads to global intron retention, widespread defects in pre-mRNA maturation, and deregulation of many essential cell processes. Importantly, genetic or pharmacologic inhibition of the spliceosome in vivo impairs survival, tumorigenicity, and metastatic proclivity of MYC-dependent breast cancers. Collectively, these data suggest that oncogenic MYC confers a collateral stress on splicing and that components of the spliceosome may be therapeutic entry points for aggressive MYC-driven cancers.

SIRT6 suppresses pancreatic cancer through control of Lin28b [miRNA-seq]

Project description:Chromatin remodeling proteins are frequently dysregulated in human cancer, yet little is known about how they control tumorigenesis. Here, we uncover an epigenetic program mediated by the NAD+-dependent histone deacetylase Sirtuin 6 (SIRT6) that is critical for suppression of pancreatic ductal adenocarcinoma (PDAC), one of the most lethal malignancies. SIRT6 inactivation accelerates PDAC progression and metastasis via upregulation of Lin28b, a negative regulator of the let-7 microRNA. SIRT6 loss results in histone hyperacetylation at the Lin28b promoter, Myc recruitment, and pronounced induction of Lin28b and downstream let-7 target genes, HMGA2, IGF2BP1 and IGF2BP3. This epigenetic program defines a distinct subset representing 30-40% of human PDAC, characterized by poor prognosis and an exquisite dependence on Lin28b for tumor growth. Thus, we identify SIRT6 as an important PDAC tumor suppressor, and uncover the Lin28b pathway as a potential therapeutic target in a molecularlydefined PDAC subset. Small RNA-Seq experiments for PLKO and shLIN28B (three replicates each) in human Panc3.27 PDAC cells to identify miRNAs modulateed by LIN28B knockdown.

MYC dependency in GLS1 and NAMPT is a therapeutic vulnerability in multiple myeloma

Project description:Multiple myeloma is an incurable hematological malignancy evolving from precursor states to advanced phases of the disease. MYC abnormalities play a critical role in the disease progression. Nevertheless, MYC lacks therapeutic drugability, thereby necessitating the exploration of alternative strategies aimed at circumventing the challenges associated with targeting MYC. In this study, we hypothesized that MYC upregulation induces genomic dependencies in tumor cells, creating vulnerabilities that can be exploited therapeutically. We discovered a differential dependency on glutamine metabolism in MYC overexpressing cells. We functionally explored these dependencies as a selective targetable vulnerability in vitro and in vivo. Furthermore, we uncovered a potential synergistic combination that can exacerbated this metabolic vulnerability, Collectively, our in vitro and in vivo results revealed an effective therapeutic combinatory strategy in the context of MYC overexpressing MM.

RNA-SEQ analysis of pancreatic ductal adenocarcinoma tumours in Pdx1-Cre;lsl-KRas[G12D] (KC), Pdx1-Cre;lsl-KRas[G12D];Rosa26-lsl-MYC[DM] (KMC), Pdx1-Cre;lsl-KRas[G12D];Rosa26-lsl-MYC[DM];c-Myc[fl/+] (KMC-Mycfl/+), and Pdx1-Cre;lsl-KRas[G12D];Rosa26-lsl-MYC[DM];Zbtb17[fl/fl] mice (KMC-Miz1fl/fl)

Project description:Activation of endogenously expressed KRas[G12D] in the pancreas of mice gives rise primarily to early stage PanIN lesions, however such lesions can occasionally progress to end-stage ductal adenocarcinoma (PDAC). Progression of KRas[G12D]- initiated lesions to PDAC is accelerated by modest expression of MYC from the Rosa26 locus. Deletion of 1 copy of endogenous c-Myc or both copies of endogenous Zbtb17 (aka Miz1), slows progression to PDAC and extends healthful survival of Pdx1-Cre;lsl-KRas[G12D];Rosa26-lsl-MYC[DM] (KMC) mice. Tumours were removed from mice with all 4 genotypes and validated by histological examination prior to RNA-SEQ analysis.
