Pancreatic ductal adenocarcinoma (PDAC) still carries a dismal prognosis with an overall 5-year survival rate of 9%. Conventional combination chemotherapies are clear advance in the treatment PDAC; however, subtypes disease exist, which exhibit extensive resistance to such therapies. Genomic MYC amplifications represent distinct subset PDAC aggressive tumour biology. It is that hyperactivation generates dependencies can be exploited therapeutically. The aim study was find and target...

Activated SUMOylation is a hallmark of cancer. Starting from targeted screening for SUMO-regulated immune evasion mechanisms, we identified an evolutionarily conserved function activated SUMOylation, which attenuated the immunogenicity tumor cells. allowed cancer cells to evade CD8+ T cell-mediated immunosurveillance by suppressing MHC class I (MHC-I) antigen-processing and presentation machinery (APM). Loss MHC-I APM frequent cause resistance immunotherapies, pharmacological inhibition...

Abstract Background We explored potential predictive biomarkers of immunotherapy response in patients with extensive-stage small-cell lung cancer (ES-SCLC) treated durvalumab (D) + tremelimumab (T) etoposide-platinum (EP), D EP, or EP the randomized phase 3 CASPIAN trial. Methods 805 treatment-naïve ES-SCLC were (1:1:1) to receive T EP. The primary endpoint was overall survival (OS). Patients required provide an archived tumor tissue block (or ≥ 15 newly cut unstained slides) at screening,...

Abstract Many targeted cancer therapies rely on biomarkers assessed by scoring of immunohistochemically (IHC)-stained tissue, which is subjective, semiquantitative, and does not account for expression heterogeneity. We describe an image analysis-based method quantitative continuous (QCS) digital whole-slide images acquired from baseline human epidermal growth factor receptor 2 (HER2) IHC-stained breast tissue. Candidate signatures patient stratification using QCS HER2 subcellular...

Signaling by the ubiquitin-related SUMO pathway relies on coordinated conjugation and deconjugation events. SUMO-specific deconjugating enzymes counterbalance SUMOylation, but comprehensive insight into their substrate specificity regulation is missing. By characterizing SENP6, we define an N-terminal multi-SIM domain as a critical determinant in targeting SENP6 to chains. Proteomic profiling reveals network of functions at crossroads chromatin organization DNA damage response (DDR). acts...

Evasion from drug-induced apoptosis is a crucial mechanism of cancer treatment resistance. The proapoptotic protein NOXA marks an aggressive pancreatic ductal adenocarcinoma (PDAC) subtype. To identify drugs that unleash the death-inducing potential NOXA, we performed unbiased drug screening experiment. In NOXA-deficient isogenic cellular models, identified inhibitor transcription factor heterodimer CBFβ/RUNX1. By genetic gain and loss function experiments, validated mode action depends on...

Abstract SUMOylation is a post-translational modification of proteins that regulates these proteins’ localization, turnover or function. Aberrant frequently found in cancers but its origin remains elusive. Using genome-wide transposon mutagenesis screen MYC-driven B-cell lymphoma model, we here identify the SUMO isopeptidase (or deconjugase) SENP6 as tumor suppressor links unrestricted to development and progression. Notably, recurrently deleted human lymphomas deficiency results...

Proteasome inhibition is a highly effective treatment for multiple myeloma (MM). However, virtually all patients develop proteasome inhibitor resistance, which associated with poor prognosis. Hyperactive small ubiquitin-like modifier (SUMO) signaling involved in both cancer pathogenesis and progression. A state of increased SUMOylation has been aggressive biology. We found that relapsed/refractory MM characterized by SUMO-high state, high expression the SUMO E1-activating enzyme (SAE1/UBA2)...

Aberrant activity of the glycoprotein 130 130/JAK/STAT3 (gp130/JAK/STAT3) signaling axis is a recurrent event in inflammation and cancer. In particular, it associated with wide range hematological malignancies, including multiple myeloma leukemia. Novel targeted therapies have only been successful for some subtypes these underlining need developing robust mouse models to better dissect role this pathway specific tumorigenic processes.

The IL-6–gp130–STAT3 signaling axis is a major regulator of inflammation. Activating mutations in the gene encoding gp130 and germline gain-of-function STAT3 (STAT3 GOF ) are associated with multi-organ autoimmunity, severe morbidity, adverse prognosis. To dissect crucial cellular subsets disease biology involved activated signaling, gp130-JAK-STAT3 was constitutively using transgene, L-gp130 , specifically targeted to T cells. cells vivo resulted fatal, early onset, autoimmunity mice that...
