Polyphenic trait promotes liver cancer in a model of epigenetic instability

Didier Trono, Sandra Eloise Kjeldsen, Marco Cassano, Suk Min Jang, Evaristo Jose Planet Letschert, Alessandra Piersigilli

Hepatocellular carcinoma (HCC) represents the fifth most common form of cancer worldwide and carries a high mortality rate due to lack of effective treatment. Males are eight times more likely to develop HCC than females, an effect largely driven by sex ho ...

Long-term usability and bio-integration of polyimide-based intraneural stimulating electrodes

Silvestro Micera, Grégoire Courtine, Nawal Noëlle Kinany, Quentin Barraud, Marco Capogrosso, Stanisa Raspopovic, Sophie Marie Marthe Wurth, Alessandra Piersigilli, Jacopo Rigosa, Jérôme Gandar

Stimulation of peripheral nerves has transiently restored lost sensation and has the potential to alleviate motor deficits. However, incomplete characterization of the long-term usability and bio-integration of intra-neural implants has restricted their us ...

RIP4 inhibits STAT3 signaling to sustain lung adenocarcinoma differentiation

Nadine Fournier, Etienne Meylan, Paolo Angelino, Jawahar Kopparam, Mauro Delorenzi, Alessandra Piersigilli, Johanna Pauline Chiffelle

Loss of epithelial differentiation and extracellular matrix (ECM) remodeling are known to facilitate cancer progression and are associated with poor prognosis in patients with lung cancer. We have identified Receptor-interacting serine/threonine protein ki ...

Neutrophils and Snail Orchestrate the Establishment of a Pro-tumor Microenvironment in Lung Cancer

Nicolas Jean Philippe Guex, Etienne Meylan, Nadine Fournier, Miguel Garcia, Alessandra Piersigilli, Julien Robert Rémi Faget, Inti Zlobec, Gael Luis Boivin, Svenja Johanna Groeneveld, Loïc Steiner

Understanding the immune compartment of tumors facilitates the development of revolutionary new therapies. We used a Kras(G12D)-driven mouse model of lung cancer to establish an immune signature and identified a contribution of Gr1 + neutrophils to disease ...

CMG2/ANTXR2 regulates extracellular collagen VI which accumulates in hyaline fibromatosis syndrome

Françoise Gisou van der Goot Grunberg, Béatrice Kunz, Laurence Gouzi Abrami, Julie Deuquet Ariosa, Alessandra Piersigilli, Jérôme Bürgi

Loss-of-function mutations in capillary morphogenesis gene 2 (CMG2/ANTXR2), a transmembrane surface protein, cause hyaline fibromatosis syndrome (HFS), a severe genetic disorder that is characterized by large subcutaneous nodules, gingival hypertrophy and ...

Angiotensin II infusion into ApoE(-/-) mice: a model for aortic dissection rather than abdominal aortic aneurysm?

Nikolaos Stergiopoulos, Lydia Aslanidou, Jessica Sordet, Bram Trachet, Alessandra Piersigilli, Patrick Segers

Aims Angiotensin II-infused ApoE(-/-) mice are a popular mouse model for preclinical aneurysm research. Here, we provide insight in the often-reported but seldom-explained variability in shape of dissecting aneurysms in these mice. Methods and results N=45 ...

Increased Myeloid Cell Production and Lung Bacterial Clearance in Mice Exposed to Cigarette Smoke

Alessandra Piersigilli

Pneumonia is a leading cause of hospitalization in patients with chronic obstructive pulmonary disease (COPD). Although most patients with COPD are smokers, the effects of cigarette smoke exposure on clearance of lung bacterial pathogens and on immune and ...

Type I Interferon Signaling Prevents IL-1 beta-Driven Lethal Systemic Hyperinflammation during Invasive Bacterial Infection of Soft Tissue

Alessandra Piersigilli

Type I interferons (IFN-Is) are fundamental for antiviral immunity, but their role in bacterial infections is contradictory and incompletely described. Streptococcus pyogenes activates IFN-I production in innate immune cells, and IFN-I receptor 1 (Ifnar1)- ...

Adamts18 deletion results in distinct developmental defects and provides a model for congenital disorders of lens, lung, and female reproductive tract development

Cathrin Brisken, Marian Caikovski, Dalya Ataca, Yakir Guri, Alessandra Piersigilli

The ADAMTS family comprises 19 secreted metalloproteinases that cleave extracellular matrix components and have diverse functions in numerous disease and physiological contexts. A number of them remain 'orphan' proteases, among them ADAMTS18, which has bee ...
