Thermally Targeted Delivery of a c-Myc Inhibitory Polypeptide Inhibits Tumor Progression and Extends Survival in a Rat Glioma Model

Treatment of glioblastoma is complicated by the tumors' high resistance to chemotherapy, poor penetration of drugs across the blood brain barrier, and damaging effects of chemotherapy and radiation to normal neural tissue. To overcome these limitations, a thermally responsive polypeptide was developed for targeted delivery of therapeutic peptides to brain tumors using focused hyperthermia. The ...

Application of thermally responsive polypeptides directed against c-Myc transcriptional function for cancer therapy.

Elastin-like polypeptides are biopolymers composed of the pentapeptide repeat Val-Pro-Gly-Xaa-Gly. Elastin-like polypeptides are soluble in aqueous solution below their transition temperature, but they hydrophobically collapse and aggregate when the temperature is raised above the transition temperature. Previous studies have suggested that the aggregation of these polypeptides in response to e...

Targeting a genetically engineered elastin-like polypeptide to solid tumors by local hyperthermia.

Elastin-like polypeptides (ELPs) are biopolymers of the pentapeptide repeat Val-Pro-Gly-Xaa-Gly that undergo an inverse temperature phase transition. They are soluble in aqueous solutions below their transition temperature (T1) but hydrophobically collapse and aggregate at temperatures greater than T1. We hypothesized that ELPs conjugated to drugs would enable thermally targeted drug delivery t...

Rational Design of “Heat Seeking” Drug Loaded Polypeptide Nanoparticles That Thermally Target Solid Tumors

This paper demonstrates the first example of targeting a solid tumor that is externally heated to 42 °C by "heat seeking" drug-loaded polypeptide nanoparticles. These nanoparticles consist of a thermally responsive elastin-like polypeptide (ELP) conjugated to multiple copies of a hydrophobic cancer drug. To rationally design drug-loaded nanoparticles that exhibit thermal responsiveness in the n...
