促凋亡肽具有诱导肿瘤细胞凋亡的作用,有望成为肿瘤治疗的有效药物。TatBim是一种由达特细胞穿透肽(CPP)和Bim细胞分裂诱导蛋白BH 3结构域融合而成的促凋亡肽。在这项研究中,基于TatBim序列,我们试图最大限度地减少CPP-Bim肽,同时保留诱导骨化的活性。CPP和Bim部分被系统地缩短,并检查缩短的肽的促凋亡活性。我们获得了TatBim-N1 C2和R8 Bim-N1 C2作为具有有效凋亡活性的最小化肽。这些肽可能在未来的生物医学研究中具有潜在的应用,例如癌症治疗。
Pro-apoptotic peptides may be promising agents for cancer therapy owing to their ability to induce apoptosis in cancer cells. TatBim, a fusion peptide of Tat cell-penetrating peptide (CPP) and the BH3 domain derived from Bim apoptosis-inducing protein, is a pro-apoptotic peptide. In this study, based on the TatBim sequence, we attempted to minimize the CPP-Bim peptide while retaining apoptosis-inducing activity. The CPP and Bim parts were systematically shortened, and the pro-apoptotic activities of the shortened peptides were examined. We obtained TatBim-N1C2 and R8Bim-N1C2 as minimized peptides with efficient apoptotic activity. These peptides may have potential applications in future biomedical studies, such as cancer therapeutics.
