Midazole-Based Ph-Sensitive Convertible Liposomes For Anticancer Drug Delivery, Ruiqi Huang

University of the Pacific Theses and Dissertations

Solid tumors possess biological features that are different from those in healthy tissues, which provides opportunities of anticancer treatment by nanomedicines. Due to the presence of the fenestrated tumor vasculatures, nanomedicines can selectively accumulate in tumor tissues by the enhanced permeability and retention (EPR) effect. The acidic pH in tumor interstitium (pH 6.0-7.0) also provides a promising mechanism to trigger the nanomedicines to promote the cellular uptake of cargo drugs. The previously reported stealth liposomes coated with PEG are known to accumulate in tumors owing to their prolonged circulation time. The PEG coating on liposomes can hinder serum protein adsorption …

Lipid-Coated Magnesium Phosphate Nanoparticles For Intrapulmonary Protein Delivery In Mice, Mallika Vadlamudi

University of the Pacific Theses and Dissertations

Proteins are a diverse category of biomolecules with great therapeutic potential. Intracellular delivery of proteins can augment the deficient activities of dysfunctional or poorly expressed innate proteins and therefore represents a promising strategy to treat the associated diseases. One major barrier to intracellular protein delivery is the translocation of the protein across the cellular membrane. Endocytosis provides an important pathway for protein nanocarriers to enter cells across the plasma membrane. However, the cargo protein must then promptly escape from the endosomes to avoid degradation in the lysosome and to exert its cellular function.

Previously, we reported a cationic lipid-coated magnesium …
