Antiestrogens and aromatase inhibitors are important drugs in the treatment of estrogen-dependent breast cancer. To investigate the effects of these drugs on gene expression in breast cancer cells, we treated estrogen receptor–positive MCF-7 cells stably transfected with the aromatase gene...
Malignant gliomas, and high-grade gliomas (HGG) in particular, are nonmetastasizing but locally infiltrating, hypervascularized brain tumors of poor prognosis. We found previously that a c-fos -inducible vascular endothelial growth factor D is ubiquitously up-regulated in HGG grade IV,...
Emerging evidence shows that the stromal cell–derived factor 1 (SDF-1)/CXCR4 interaction regulates multiple cell signaling pathways and a variety of cellular functions such as cell migration, proliferation, and survival. There is little information linking the cellular functions and individual...
Until recently, tumor progression has been considered a multistep process defined by tumor cell mutations and the importance of the surrounding stroma poorly understood. It is now recognized that matrix-degrading enzymes that promote tumor cell invasion are elaborated by both tumor cells and...
Tumor necrosis factor–related apoptosis-inducing ligand (TRAIL) has been shown to induce apoptosis of cancer cells. Sensitization of cancer cells to TRAIL, particularly TRAIL-resistant cancer cells, could improve the effectiveness of TRAIL as an anticancer agent. The adenovirus type 5 E1A that...
Crk adaptor proteins play an important role during cellular signaling by mediating the formation of protein complexes. Increased levels of Crk proteins are observed in several human cancers and overexpression of Crk in epithelial cell cultures promotes enhanced cell dispersal and invasion,...
