Translational control: the cancer connection.
There is now a growing body of evidence which suggests links between the regulation of protein synthesis and the disruption of cell behaviour that typifies cancer. This directed issue of the International Journal of Biochemistry and Cell Biology presents several review articles of relevance to this field. The topics covered include the significance of the regulation and overexpression of polypeptide chain initiation factors for cell transformation and malignancy, the role of mRNA structure in the control of synthesis of key growth regulatory proteins, the actions of the eIF2 alpha-specific protein kinase PKR in the control cell growth and apoptosis, and the involvement of the elongation factor eEF1 in oncogenesis. The purpose of this article is to give an overview of the field and to indicate where we may expect developments to occur in the next few years.
