Role of angiopoietin-2 in adaptive tumor resistance to VEGF signaling blockade

Ioanna Keklikoglou, Michele De Palma, Ece Kadioglu, Nicolo Rigamonti, Céline Wyser Rmili

Angiopoietin-2 (ANG2/ANGPT2) is a context-dependent TIE2 receptor agonist/antagonist and proangiogenic factor. Although ANG2 neutralization improves tumor angiogenesis and growth inhibition by vascular endothelial growth factor (VEGF)-A signaling blockade, ...

Targeting and Modulating Tumor-Associated Sites with Novel Nanoparticle-Based Immunotherapies

Laura Jeanbart

Cancer is a global disease and a leading cause of death worldwide. While surgery, radiotherapy and chemotherapy comprise the classical tools to eradicate tumors, they do not cure cancer, cannot prevent metastases, lead to side effects, and most importantly ...

The promotion of endothelial cell attachment and spreading using FNIII10 fused to VEGF-A(165)

Mikaël Martino, Jeffrey Alan Hubbell, Melody Swartz

Synergy in the downstream signaling pathways of the vascular endothelial growth factor receptor-2 (VEGFR-2) and the integrin alpha v beta 3 is critical for blood vessel formation. Thus, agents that activate both receptors could possess efficient pro-angiog ...

Secreted semaphorin 5A suppressed pancreatic tumour burden but increased metastasis and endothelial cell proliferation

Anguraj Sadanandam, Stephan Wullschleger

BACKGROUND: Our earlier reports demonstrated that membrane-bound semaphorin 5A (SEMA5A) is expressed in aggressive pancreatic cancer cells and tumours, and promotes tumour growth and metastasis. In this study, we examine whether (1) pancreatic cancer cells ...

Angiostatic kinase inhibitors to sustain photodynamic angio-occlusion

Hubert van den Bergh, Patrycja Nowak-Sliwinska, Blaise Lovisa

Targeted angiostatic therapy receives major attention for the treatment of cancer and exudative age-related macular degeneration (AMD). Photodynamic therapy (PDT) has been used as an effective clinical approach for these diseases. Since PDT can cause an an ...

ADAM17 Silencing in Mouse Colon Carcinoma Cells: The Effect on Tumoricidal Cytokines and Angiogenesis

Melody Swartz, Renata Katarzyna Mezyk-Kopec

ADAM17 (a disintegrin and metalloprotease 17) is a major sheddase for numerous growth factors, cytokines, receptors, and cell adhesion molecules and is often overexpressed in malignant cells. It is generally accepted that ADAM17 promotes tumor development ...

Angiopoietin 2 stimulates TIE2-expressing monocytes to suppress T cell activation and to promote regulatory T cell expansion

Michele De Palma

Angiopoietin 2 (ANGPT2) is a proangiogenic cytokine whose expression is often upregulated by endothelial cells in tumors. Expression of its receptor, TIE2, defines a highly proangiogenic subpopulation of myeloid cells in circulation and tumors called TIE2- ...

Proangiogenic Tie2(+) macrophages infiltrate human and murine endometriotic lesions and dictate their growth in a mouse model of the disease

Michele De Palma, Daniela Biziato, Stefano Ferrari

Endometriosis affects women of reproductive age, causing infertility and pain. Although immune cells are recruited in endometriotic lesions, their role is unclear. Tie2-expressing macrophages (TEMs) have nonredundant functions in promoting angiogenesis and ...

Targeting the ANG2/TIE2 axis inhibits tumor growth and metastasis by impairing angiogenesis and disabling rebounds of proangiogenic myeloid cells

Michele De Palma, Ferdinando Pucci

Tumor-infiltrating myeloid cells convey proangiogenic programs that counteract the efficacy of antiangiogenic therapy. Here, we show that blocking angiopoietin-2 (ANG2), a TIE2 ligand and angiogenic factor expressed by activated endothelial cells (ECs), re ...
