Regulation and function of a hemicleaved Activin-A processing intermediate in melanoma

Manon Bulliard

Activin-A is a Transforming Growth Factor-B (TGFB)-related cytokine that regulates various biological processes including cell proliferation and differentiation through autocrine, paracrine or endocrine signaling. Activin-A expression is upregulated in mul ...

Transposon-activated POU5F1B promotes colorectal cancer growth and metastasis

Didier Trono, Laurence Gouzi Abrami, Julien Léonard Duc, Sandra Eloise Kjeldsen, Alexandre Coudray, Sagane Dind, Evaristo Jose Planet Letschert, Laia Simo Riudalbas

The treatment of colorectal cancer (CRC) is an unmet medical need in absence of early diagnosis. Here, upon characterizing cancer-specific transposable element-driven transpochimeric gene transcripts (TcGTs) produced by this tumor in the SYSCOL cohort, we ...

Apelin-driven endothelial cell migration sustains intestinal progenitor cells and tumor growth

Mauro Delorenzi, Stefanie Siegert, Pascale Anderle Pedone, Nadine Fournier, Sina Nassiri, François Renevey, Michele De Palma, Mario Leonardo Squadrito, Simone Ragusa

Stem and progenitor cells residing in the intestinal crypts drive the majority of colorectal cancers (CRCs), yet vascular contribution to this niche remains largely unexplored. Vascular endothelial growth factor A (VEGFA) is a key driver of physiological a ...

Integrative transcriptome analyses of Transposable Elements (TEs) and genes contribute to a better understanding of colorectal cancer

Eunji Shin

Cancer is the second leading cause of death worldwide. Cancer develops through multiple hallmark functions including apoptosis evasion, unlimited replicative potential, metastasis, and immune avoidance. Over the past few decades, researchers have reported ...

High-content, targeted RNA-seq screening in organoids for drug discovery in colorectal cancer

Jörg Hülsken, Paloma Ordonez Moran, Maxim Norkin

Organoids allow the recapitulation of intestinal homeostasis and cancerogenesis in vitro; however, RNA sequencing (RNA-seq)-based methods for drug screens are missing. We develop targeted organoid sequencing (TORNADO-seq), a high-throughput, high-content d ...

Emodin Inhibits Inflammation, Carcinogenesis, and Cancer Progression in the AOM/DSS Model of Colitis-Associated Intestinal Tumorigenesis

Jelena Zaric

Colorectal cancer (CRC) is one of the most common cancer worldwide. Chronic inflammation contributes to CRC development and progression. Emodin, is a natural anthraquinone derivative with anti-oxidant, anti-inflammatory, and anti-tumor activities. We used ...

Neutrophils suppress tumor-infiltrating T cells in colon cancer via matrix metalloproteinase-mediated activation of TGF beta

Marc-Olivier Sauvain, Freddy Radtke, Mauro Delorenzi, Nadine Fournier, Markus Germann, George Coukos, Amber Dawn Bowler

High T-cell infiltration in colorectal cancer (CRC) correlates with a favorable disease outcome and immunotherapy response. This, however, is only observed in a small subset of CRC patients. A better understanding of the factors influencing tumor T-cell re ...

Bioengineering Methods to Improve in vitro Adoptive Cell Therapy based on Tumor-Infiltrating Lymphocytes

François Réal Rivest

Cancer is one of the biggest medical challenges of our times, with a devastating impact across all social categories. Accordingly, considerable efforts are geared towards improving the standard of care. Among them, immunotherapy, which relies on the immune ...

RasGRP1 is a potential biomarker for stratifying anti-EGFR therapy response in colorectal cancer

Mauro Delorenzi, Delphine Yvette L Grun

Colorectal cancer (CRC) is the third most frequent neoplastic disorder and is a main cause of tumor-related mortality, as many patients progress to stage IV metastatic CRC. Standard care consists of combination chemotherapy (FOLFIRI or FOLFOX). Patients wi ...

Classification of Healthy and Cancer States of Colon Epithelial Tissues Using Opto-magnetic Imaging Spectroscopy

Ivan Dimitrijevic, Marko Baros

Colorectal carcinoma (CRC) as a major health problem in industrialized countries is highly preventable and can be successfully treated in the early stages. However, incidence and mortality of CRC has increased over the last two decades. The reason could be ...

Rapid activation of tumor-associated macrophages boosts preexisting tumor immunity

Michele De Palma, Wei Xu

Depletion of immunosuppressive tumor-associated macrophages (TAMs) or reprogramming toward a proinflammatory activation state represent different strategies to therapeutically target this abundant myeloid population. In this study, we report that inhibitio ...

The role of Snail in non-small cell lung cancer

Svenja Johanna Groeneveld

The epithelial-to-mesenchymal transition (EMT) is a developmental program frequently reactivated in cancer. It plays an important role in several aspects of tumor progression, particularly in the acquisition of invasive capacities facilitating metastasis. ...

Label-free nanoplasmonic sensing of tumor-associate autoantibodies for early diagnosis of colorectal cancer

Maria Soler Aznar

Colorectal cancer is treatable and curable when detected at early stages. However there is a lack of less invasive and more specific screening and diagnosis methods which would facilitate its prompt identification. Blood circulating autoantibodies which ar ...
