Résumé :

Breast cancer remains one of the leading causes of cancer morbidity and mortality. Despite significant advances in treatment of breast cancer a substantial proportion of women affected by this disease succumb to it. Survival of patients with advanced disease, chemoresistant tumors or a suboptimal response to endocrine therapy is significantly shortened. Hence, further understanding of disease pathogenesis is required to enhance the arsenal of approaches to cure this deadly ailment. Recent advances in biochemistry, molecular cell biology and cancer research highlighted the importance of dysregulation of protein synthesis, translation, in the development and progression of tumors. This dysregulation appears to take place at an early stage of translation, called translation initiation, that is a highly controlled and rate-limiting step of the protein synthesis. In this chapter we summarize decades of knowledge accumulated in regards to the role of translation and its regulation in the development and progression of breast cancer. We then extensively discuss applications of this knowledge in diagnosis and treatment of breast cancer.
