A unique galectin signature in human prostate cancer progression suggests galectin-1 as a key target for treatment of advanced disease
Galectins, a family of glycan-binding proteins, influence tumor progression by modulating interactions between tumor, endothelial, stromal, and immune cells. Despite considerable progress in identifying the roles of individual galectins in tumor biology, an integrated portrait of the galectin networ...

In human prostate cancer tissue arrays, Gal-1 expression correlated with the presence of blood vessels, particularly in advanced stages of the disease. Silencing Gal-1 in prostate cancer cells reduced tumor vascularization without altering expression of other angiogenesis-related genes. Collectively, our findings identify a dynamically regulated "galectin-specific signature" that accompanies disease evolution in prostate cancer, and they highlight a major role for Gal-1 as a tractable target for antiangiogenic therapy in advanced stages of the disease. ©2012 AACR. 2013 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00085472_v73_n1_p86_Laderach http://hdl.handle.net/20.500.12110/paper_00085472_v73_n1_p86_Laderach |
