title: Deregulation of protein synthesis as a mechanism of neoplastic transformation.
abstract: Early research on the cell cycle revealed correlations between protein accumulation and cell proliferation. In this review, I describe the data showing that abnormality of cell growth and tumor development are dependent upon oncogene-induced increases in the levels and activity of factors that determine the rate of protein synthesis. It is proposed that the establishment of a vicious circle, namely oncoproteins-->increase in translation-->oncoproteins, is a major biological mechanism that fuels neoplastic growth. The constitutively high rates of protein synthesis and accumulation of proteins, including those necessary for DNA replication and mitosis, would drive cells to excessive proliferation.
