Tuning a polar molecule for selective cytoplasmic delivery by a pH (Low) insertion peptide.

Drug molecules are typically hydrophobic and small in order to traverse membranes to reach cytoplasmic targets, but we have discovered that more polar molecules can be delivered across membranes using water-soluble, moderately hydrophobic membrane peptides of the pHLIP (pH low insertion peptide) family. Delivery of polar cargo molecules could expand the chemical landscape for pharmacological ag...

Accurate Analysis of Tumor Margins Using a Fluorescent pH Low Insertion Peptide (pHLIP)

The recurrence of certain cancers remains quite high due to either incomplete surgical removal of the primary tumor or the presence of small metastases that are invisible to the surgeon. Near infrared (NIR) fluorescence imaging might improve surgical outcomes by providing sensitive, specific, and real-time visualization of normal and diseased tissues if agents can be found that discriminate bet...

Tumor-targeted gene delivery using molecularly engineered hybrid polymers functionalized with a tumor-homing peptide.

Before gene therapy can be used in clinical settings, safe and efficient DNA delivery systems must be developed to overcome a range of extra- and intracellular transport barriers. As a step toward the development of a modular, multifunctional gene delivery system to overcome these diverse barriers, we have developed a family of linear-dendritic "hybrid" polymers which contain functionalities fo...

Imaging Tumor Acidity: pH-Low Insertion Peptide Probe for Optoacoustic Tomography.

Optoacoustic tomography has been used for the detection of pancreatic ductal adenocarcinoma targeted by pH-low insertion peptide (pHLIP) conjugated to near-infrared fluorescent dye. It was proved that tumor targeting is pH dependent. The approach could have major implication for detection and monitoring of pancreatic and other cancers.

pH (low) insertion peptide (pHLIP) targets ischemic myocardium.

The pH (low) insertion peptide (pHLIP) family enables targeting of cells in tissues with low extracellular pH. Here, we show that ischemic myocardium is targeted, potentially opening a new route to diagnosis and therapy. The experiments were performed using two murine ischemia models: regional ischemia induced by coronary artery occlusion and global low-flow ischemia in isolated hearts. In both...
