Notes: A11 is a cell-penetrating peptide composed of the HIV-1 Tat protein transduction domain linked to an 11-amino acid peptide corresponding to residues 20-30 of the annexin A1 N-terminus.{67535} It decreases annexin A1 binding to Eph receptor tyrosine kinase A2 (EphA2) and increases EphA2 ubiquitination in HK1 nasopharyngeal carcinoma (NPC) cells. A11 (10 µM) inhibits HK1 and 5-8F NPC cell proliferation, migration, and invasion. In vivo, A11 reduces tumor volume in 5-8F and HK1 NPC mouse xenograft models.
