Thymosin ∫-10 (T∫-10) is a member of the highly conserved ∫-thymosin family. It is a monomeric G-Actin sequestering protein of the cytoplasm that regulates Actin dynamics. T∫-10 consists of 43 amino acids and often forms å-helical structures. T∫-10 has been shown to act as an Actin-mediated tumor suppressor. Overexpression of this protein inhibits endothelial cell proliferation, migration, invasion and tube formation. In human ovarian cancer cells, T∫-10 also increases apoptosis frequency. T∫-10 directly interacts with Ras, resulting in inhibition of the Ras downstream signaling pathways which, in turn, exhibits a negative effect on angiogenesis and tumor growth. More specifically, this inhibitive effect might be mediated by the downregulation of vascular endothelial growth factor (VEGF), VEGF receptor-1 (VEGFR-1) and Integrin åV, which suggests a role for T∫-10 in anticancer therapy. |
