Anti-HB-EGF Antibody-Mediated Delivery of siRNA to Atherosclerotic Lesions in Mice.

For atherosclerotic cardiovascular diseases (ACD), gene therapy may be a potential therapeutic strategy; however, lack of effective and safe methods for gene delivery to atherosclerotic plaques have limited its potential therapeutic applications. To overcome this limitation, we developed a novel antibody-based gene delivery system (anti-HB-EGF/NA vector) by chemically crosslinking antibodies against human heparin-binding epidermal growth factor-like growth factor (HB-EGF). It has been shown to be excessively expressed in human atherosclerotic plaques and NeutrAvidin (NA) for conjugating biotinylated siRNA.

Development of a novel one-step production system for injectable liposomes under GMP.

There are few methods available for injectable liposome production under good manufacturing practices (GMP). Injectable liposome production processes under GMP generally consist of liposome formation, size homogenization, organic solvent removal, liposome concentration control and sterilization. However, these complicated and separate processes make it difficult to maintain scalability, reproducibility and sterility.

Targeted Therapy for Acute Autoimmune Myocarditis with Nano-Sized Liposomal FK506 in Rats.

Immunosuppressive agents are used for the treatment of immune-mediated myocarditis; however, the need to develop a more effective therapeutic approach remains. Nano-sized liposomes may accumulate in and selectively deliver drugs to an inflammatory lesion with enhanced vascular permeability. The aims of this study were to investigate the distribution of liposomal FK506, an immunosuppressive drug encapsulated within liposomes, and the drug's effects on cardiac function in a rat experimental autoimmune myocarditis (EAM) model.

Chemical Endoplasmic Reticulum Chaperone Alleviates Doxorubicin-Induced Cardiac Dysfunction.

Rationale: Doxorubicin is an effective chemotherapeutic agent for cancer, but its use is often limited by cardiotoxicity. Doxorubicin causes endoplasmic reticulum (ER) dilation in cardiomyocytes, and we have demonstrated that ER stress plays important roles in the pathophysiology of heart failure.

Objective: We evaluated the role of ER stress in doxorubicin-induced cardiotoxicity and examined whether the chemical ER chaperone could prevent doxorubicin-induced cardiac dysfunction.
