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 ...

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 ...

Tumor-educated Gr1+CD11b+cells drive breast cancer metastasis via OSM/IL-6/JAK-induced cancer cell plasticity

Nadine Fournier, Manon Bulliard, Annamaria Kauzlaric, Yu-Ting Huang, Rachel Marcone

Cancer cell plasticity contributes to therapy resistance and metastasis, which represent the main causes of cancer-related death, including in breast cancer. The tumor microenvironment drives cancer cell plasticity and metastasis, and unraveling the underl ...

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 ...
