Abstract

Ras proteins control at least three crucial signalling networks responsible for several cellular processes including anchorage independence, survival, and proliferation. Point mutations in one of the three ras genes are frequent in human tumours. In these tumours, Ras oncoproteins contribute significantly to the malignant phenotype, including deregulation of tumour-cell growth, apoptosis and invasiveness, and the ability to induce angiogenesis. Although significant strides have been made in understanding Ras biology, the collaborative actions of Ras effectors are still poorly understood. Here, we describe a proteomics approach to study global changes in protein expression in Ras-transformed ..
