In pursuit of an effective vaccine to end the global HIV-1/AIDS pandemic, researchers at the Vaccine Research Center (“VRC”) continue to study the structure of HIV-1. Recently, these researchers have determined the three-dimensional structure of the HIV-1 Envelope trimeric ectodomain (“Env”), comprised of three gp120 and three gp41 subunits, in its prefusion, mature, closed conformation.

This technology includes the administration of the antiglucocorticoid mifepristone for the treatment of diabetes. Administration of mifepristone (50 mg orally every 6 hours) for one week improves hepatic and adipose insulin resistance in men and women with pre-diabetes or mild type 2 diabetes mellitus.

This technology includes polyclonal antibodies against MLL3 (KMT2C), MLL4, PA1, UTX And PTIP for the development of treatments for development diseases and cancer. Enhancers play a central role in cell-type-specific gene expression and are marked by H3K4me1/2. Active enhancers are further marked by H3K27ac. However, the methyltransferases responsible for H3K4me1/2 on enhancers remain elusive. Furthermore, how these enzymes function on enhancers to regulate cell-type-specific gene expression is unclear.

This technology includes a plasmid (designated pJH114) that encodes all five subunits of the E. coli Bam (barrel assembly machine) complex under the control of an inducible promoter to be used in the study of the Bam and screen for therapeutic small molecules. The Bam (barrel assembly machine) complex is a highly conserved heterooligomer that catalyzes the integration of membrane proteins that have a beta barrel structure into the outer membrane of Gram-negative bacteria. Research suggests that this complex is essential for the viability of most, if not all bacteria in this class.

This technology includes a semi-automatic and affordable protein purification system that produces purified proteins with yields and purities comparable to an automatic protein purification system for less than 10% of its cost, which can be used for studying protein structure and function, as well as antibody purifications and drug screenings. Additionally, the new system is flexible and customizable for use with both custom-made and commercial pre-made resin columns with either gravity flow or low-pressure configurations.

The vast majority of people infected with Hepatitis C Virus (HCV) will have chronic infection. Over decades, this can lead to liver disease and liver cancer. In fact, HCV infection is the leading cause of liver transplants in the U.S. Several new drugs have recently come into the market that will likely change the HCV treatment paradigm. However, the effectiveness of these new drugs can vary depending on the HCV genotype. Thus, there is still the need for additional new therapeutics against HCV.

Summary:

NCI is seeking research co-development partners and/or licensees to evaluate, further develop or commercialize this high efficacy vaccine and microbicide combination for use against HIV. 

Description of Technology:

The Transforming Growth Factor Beta (TGF-ß) ligands (i.e., TGF-ß1, -ß2, -ß3) are key regulatory proteins in animal physiology. Disruption of normal TGF-ß signaling is associated with many diseases from cancer to fibrosis. In mice and humans, TGF-ß activates TGF-ß receptors (e.g., TGFBR1), which activates SMAD proteins that alter gene expression and contribute to tumorigenesis.  Reliable animal models are essential for the study of TGF-ß signaling.
