We previously reported that transgenic (TG) mice over‐expressing translationally controlled tumor protein (TCTP) developed systemic arterial hypertension at about 6 weeks after birth. In the present study, we identified, using proteomics technologies, 24 other proteins that were differentially expressed in the heart of TCTP over‐expressing TG mice. These 24 proteins are involved in a variety of biological processes such as reactive oxygen species metabolism, cytoskeleton organization, fatty acid metabolism, amino acid metabolism and energy metabolism. We determined protein expression levels of the peroxiredoxin (Prx)2, Prx3, myosin light chain 1, stress protein (heat shock protein) 25K, and T‐complex protein 1 alpha subunit by western blot analysis. Over‐expression of TCTP probably regulates the expression of other proteins which play a pivotal role in a variety of cellular functions in TCTP over‐expressing TG mice.
