By analyzing the gene expression profile between tumor cells and revertant counterparts that have a suppressed malignant phenotype, we previously reported a significant down-regulation of translationally controlled tumor protein (TCTP) in the revertants. In the present study, we derived, by using the H1 parvovirus as a selective agent, revertants from three(More)
Translationally controlled tumor protein (TCTP) is a potential target for cancer therapy. It functions as a growth regulating protein implicated in the TSC1–TSC2 –mTOR pathway or a guanine nucleotide dissociation inhibitor for the elongation factors EF1A and EF1Bβ. Accumulating evidence indicates that TCTP also functions as an antiapoptotic protein, through(More)
TSAP6 (tumor suppressor-activated pathway 6), also known as Steap3, is a direct p53 transcriptional target gene. It regulates protein secretion, for example translationally controlled tumor protein (TCTP), which is implicated in tumor reversion. In keeping with the latter, we show herein that TSAP6 is a glycosylated protein present in the trans-Golgi(More)
RATIONALE AND OBJECTIVE Membrane-shed submicron microparticles (MPs) released following cell activation or apoptosis accumulate in atherosclerotic plaques, where they stimulate endothelial proliferation and neovessel formation. The aim of the study was to assess whether or not MPs isolated from human atherosclerotic plaques contribute to increased(More)
Siah proteins are E3 ubiquitin ligases. They are homologues of the Drosophila seven in absentia (Sina), a protein required for the R7 photoreceptor development. We have previously found that the expression of human siah-1 and its mouse homologue siah-1b are induced by p53 during apoptosis and tumor reversion. So far, no evidence that the siah-1b gene is a(More)
The translationally controlled tumor protein (TCTP), also known as histamine-releasing factor (HRF), is encoded by a gene (Tpt1) that is highly conserved throughout phylogeny. TCTP is implicated in cell growth, acute allergic response, and apoptosis. In the present study, seven putative Tpt1 genes with different chromosomal localizations were identified in(More)
