Anticancer drug targets: growth factors and growth factor signaling

Anticancer drug targets: growth factors and growth factor signaling.

Phosphoproteomic fingerprinting of epidermal growth factor signaling and anticancer drug action in human tumor cells.

Many proteins regulating cancer cell growth are tyrosine phosphorylated. Using antiphosphotyrosine affinity chromatography, thiourea protein solubilization, two-dimensional PAGE, and mass spectrometry, we report here the characterization of the epidermal growth factor (EGF)-induced phosphoproteome in A431 human epidermoid carcinoma cells. Using this approach, more than 50 distinct tyrosine phos...

Anticancer drug targets: approaching angiogenesis.

Fibroblast growth factor homologous factors are intracellular signaling proteins

Fibroblast growth factors (FGFs) mediate cell growth, differentiation, migration, and morphogenesis by binding to the extracellular domain of cell surface receptors, triggering receptor tyrosine phosphorylation and signal transduction [1-5]. FGF homologous factors (FHFs) were discovered within vertebrate DNA sequence databases by virtue of their sequence similarity to FGFs [3, 6, 7], but the me...

Epidermal growth factor receptor signaling

The epidermal growth factor receptor (EGFR) is a long known, versatile signal transducer that has been well conserved during evolution. It functions in a wide range of cellular processes including cell fate determination, proliferation, cell migration and apoptosis. The activity of the EGFR is subject to modulation by multiple positive and negative regulators and is transduced to the nucleus by...
