Compacted DNA nanoparticles deliver transgenes efficiently to the lung following intrapulmonary dosing. Here we show that nucleolin, a protein known to shuttle between the nucleus, cytoplasm, and cell surface, is a receptor for DNA nanoparticles at the cell surface. By using surface plasmon resonance (SPR), we demonstrate that nucleolin binds to DNA(More)
DNA nanoparticles (DNPs) are nonviral gene transfer vectors with excellent in vivo potential. Previously, we reported that cell surface nucleolin directly binds DNPs, and functions as an important receptor for DNPs. However, the fate of the nucleolin-DNP complex following cellular uptake remains elusive. In this study, we examined the role of lipid rafts in(More)
Gastric cancer is one of the most prevalent and deadliest forms of cancer worldwide. Even though neoadjuvant, perioperative, and adjuvant chemotherapy and/or radiation therapy may improve outcomes compared with surgery alone, the optimal combination of treatment modalities remains controversial. While European and North American trials established(More)
Chronic inflammation is a hallmark of cancer. Inflammatory chemokines, such as C-C chemokine ligand 2 (CCL2), are often present in tumors but their roles in cancer initiation and maintenance are not clear. Here we report that CCL2 promotes mammary carcinoma development in a clinically relevant murine model of breast cancer. Targeted disruption of Ccl2(More)
