title: [Role of the stress protein p8 in tumor progression and development of metastasis].
abstract: In spite of the great advances made on the knowledge of cancer etiology and the significant breakthroughs in terms of treatment, complete remission is obtained in only around half of cancer patients. In fact, therapies that appear successful for some cancers are totally unfruitful for others, and some cancer types still remain incurables. In order to develop new therapies suitable to these tenacious cancers, we need to renew our view on cancer and to revise some old paradigms and "false friends" that can hide unexpected new therapeutic targets. A good example of these paradigms is the role of the cell stress response in tumor progression. Indeed, a number of studies has been devoted to the pivotal tumor suppressor function of some players of this response, of which the p53 protein is the best example. Nevertheless, during tumor progression and metastasis, the cancer cell faces many stresses imposed by tumor microenvironment and its survival will be conditioned by an efficient cell stress response. This review is consecrated to the role played by a pivotal actor of the cell stress response, the p8 protein, during carcinogenesis. We will recapitulate the data available on its different cell functions and the assets p8 confer to the cancer cell in terms of growth, drugs resistance and metastasis formations.
