Tumor-Penetrating Peptides
Tumor-homing peptides can be used to deliver drugs into tumors. Phage library screening in live mice has recently identified homing peptides that specifically recognize the endothelium of tumor vessels, extravasate, and penetrate deep into the extravascular tumor tissue. The prototypic peptide of this class, iRGD (CRGDKGPDC), contains the integrin-binding RGD motif. RGD mediates tumor-homing th...
متن کامل[Anti-tumor efficacy of P53 with 9R cell-penetrating peptides].
To enhance the penetration of P53 into tumor cells by fusion it with the cell penetrating peptide 9R. The fusion gene of 9R-p53 was cloned into the expression vector. The fusion protein, CPPs-P53, was expressed and purified. We detected the rate of cell growth inhibition and apoptosis by MTT and Annexin-V-FITC/PI double stained method respectively for measuring its effect on tumor cells. CPPs-P...
متن کاملCell Penetrating Peptides
During the last ten years it has been observed that a number of peptides and proteins are able to penetrate the cell membrane and enter the cell. Furthermore, it has been shown that even many cargo molecules that are covalently attached to these peptides will be translocated into the cell. Peptides that show the ability to translocate through the cell membrane are usually short peptides of less...
متن کاملArginine-rich cell-penetrating peptides.
Arginine-rich cell-penetrating peptides are short cationic peptides capable of traversing the plasma membranes of eukaryotic cells. While successful intracellular delivery of many biologically active macromolecules has been accomplished using these peptides, their mechanisms of cell entry are still under investigation. Recent dialogue has centered on a debate over the roles that direct transloc...
متن کاملIncreasing Tumor Accessibility with Conjugatable Disulfide-Bridged Tumor-Penetrating Peptides for Cancer Diagnosis and Treatment
Tumor-homing peptides with tissue-penetrating properties increase the efficacy of targeted cancer therapy by delivering an anticancer agent to the tumor interior. LyP-1 (CGNKRTRGC) and iRGD (CRGDKGPDC) are founding members of this class of peptides. The presence of the cysteines forming the cyclizing disulfide bond complicates conjugation of these peptides with other molecules, such as drugs. H...
