This review describes the key role of the serine-threonine kinase like protein Tribbles-1 in health as well as in diverse human pathologies. Tribbles-1 is a homolog protein of the Drosophila Tribbles. In Drosophila, the Tribbles protein is involved in the cell-cycle progression during mitosis and in mammals initial data showed TRIB1 to be involved in cell proliferation. In mammals, TRIB1 lacks a catalytic domain and thus acts as an adaptor protein by interacting with several partners. The activity of TRIB1 seems to be very specific to the environment and the cells type in which it is expressed, and a role for this molecule has been mainly described in several pathological states including various cancers such as acute myeloid leukemia and ovarian cancer. Further evidence has also linked TRIB1 to the control of plasmalipid homeostasis thus indicating the role of this molecule as a risk factor for myocardial infarction. Finally, TRIB1 is shown to be up-regulated during inflammatory events such as chronic inflammation of atherosclerotic arteries or chronic antibody-mediated rejection of transplanted organs. Here we provide a review of the current state of the scientific literature for TRIB1, highlighting its role in diverse pathologies and inflammatory states. A better understanding of the role of this protein as both a target as well as a biological marker in diseases should drive the development of new therapeutic strategies.
