Kallikrein-8 mediates furin-independent Activin-A precursor processing to stimulate tumor growth in melanoma

Daniel Constam, Nadine Fournier, Manon Bulliard, Céline Emmanuelle Schmuziger, Katarina Pinjusic

Receptor binding of TGF-β and related ligands such as Activin-A requires cleavage of a furin site in their dimeric precursor proteins. Melanoma cells cleave one Activin-A subunit independently of furin and related proprotein convertases, raising questions ...

Inhibition of anti-tumor immunity by melanoma cell-derived Activin-A depends on STING

Daniel Constam, Giovanna Ambrosini, Nicolas Jean Philippe Guex, Christian Iseli, Katarina Pinjusic

The transforming growth factor-beta (TGF-beta) family member activin A (hereafter Activin-A) is overexpressed in many cancer types, often correlating with cancer-associated cachexia and poor prognosis. Activin-A secretion by melanoma cells indirectly imped ...

Stepwise release of Activin-A from its inhibitory prodomain is modulated by cysteines and requires furin coexpression to promote melanoma growth

Hatice Altug, Daniel Constam, Benjamin Marcel Daniel Rothé, Saeid Ansaryan, Pierpaolo Ginefra, Manon Bulliard, Céline Emmanuelle Schmuziger, Katarina Pinjusic

The Activin-A precursor dimer can be cleaved by furin, but how this proteolytic maturation is regulated in vivo and how it facilitates access to signaling receptors is unclear. Here, analysis in a syngeneic melanoma grafting model shows that without furin ...

Immunosuppressive roles of Activin-A in melanoma and characterization of its precursor cleavage

Katarina Pinjusic

Activin-A, a transforming growth factor ê µ family member, is a pleiotropic cytokine with diverse functions in development, fertility, adult tissue homeostasis, and aging. Accordingly, deregulation of Activin-A signaling has been associated with many patho ...

Activin-A impairs CD8 T cell-mediated immunity and immune checkpoint therapy response in melanoma

Daniel Constam, Etienne Meylan, Julien Robert Rémi Faget, Olivier Andreas Dubey, Katarina Pinjusic

Background Activin-A, a transforming growth factor beta family member, is secreted by many cancer types and is often associated with poor disease prognosis. Previous studies have shown that Activin-A expression can promote cancer progression and reduce the ...

Time-Resolved Scanning Ion Conductance Microscopy for Three-Dimensional Tracking of Nanoscale Cell Surface Dynamics

Aleksandra Radenovic, Georg Fantner, Daniel Constam, Alexandre Louis André Persat, Barney Frederick Drake, Adrian Pascal Nievergelt, Vytautas Navikas, Samuel Mendes Leitão, Xavier Jean-Yves Pierrat, Charlène Cécile Geneviève Brillard

Nanocharacterization plays a vital role in understanding the complex nanoscale organization of cells and organelles. Understanding cellular function requires high-resolution information about how the cellular structures evolve over time. A number of techni ...
