The articles in the present volume are by major contributors to our under standing of signaling pathways affecting protein synthesis. They focus pri marily on two extracellular anabolic signals, although others are included as well. Insulin is one of the best-studied extracellular regulators of protein syn thesis. Several of the known pathways for regulation of protein synthesis were elucidated using insulin-dependent systems. Regulation of protein synthesis by amino acids, by contrast, is an emerging field that has recently received a great deal of attention. The dual role of amino acids as...

This volume presents the response of the eukaryotic translational apparatus to cellular stress and apoptosis, including kinases activated through both the ERK and stress-activated pathways. It further explores two agents that inhibit protein synthesis, calcium and the immunosuppressant rapamycin. Six chapters written by leading experts in the field provide both new data and comprehensive literature reviews. Both the regulation of initiation and elongation are discussed, and the mechanisms of apoptosis are related to changes in the protein synthesis machinery.
