Multifunctional RNA Nanoparticles as Cancer and HIV Therapeutics

The promise of RNA interference based therapeutics is made evident by the recent surge of biotechnological drug companies that pursue such therapies and their progression into human clinical trials. The present invention discloses novel RNA  and RNA/DNA nanoparticles including  multiple siRNAs, RNA aptamers, fluorescent dyes, and proteins. These RNA nanoparticles are useful for various nanotechnological applications.

Improved Production of Prenylated Protein in Insect Cells

KRAS and other Ras-family enzymes are an important component of over 30% of human cancers, however, no effective therapeutics targeting Ras or Ras-driven cancers are currently available.  The production of Ras proteins in vitro is required for the identification and characterization of Ras targeting drugs.  An important step in producing the Ras protein involves prenylation of the C-terminus of the protein via farnesyltransferase, a modification that does not occur in prokaryotic organisms.  Previous attempts to generate properly processed Ras in eukaryotic cells has

PARP Inhibitor and NO-Donor Dual Prodrugs as Anticancer Agents

Poly-ADP ribose polymerase-1 (PARP-1) is a critical enzyme involved in DNA repair.  The inhibition of PARP has emerged as a promising strategy in cancer therapy.  Numerous PARP inhibitors have been developed and advanced into clinical trials, both for use as single agents in specific patient populations and as combination therapies with various chemotherapeutics.  The induction of strand break damage to DNA, as has been demonstrated in cancer cells treated with O2-arylated diazeniumdiolates, coupled with inhibition of DNA repair by PARP inhibitors, represents a novel rational

Mouse Model for the Preclinical Study of Metastatic Disease

The successful development of new cancer therapeutics requires reliable preclinical data that are obtained from mouse models for cancer. Human tumor xenografts, which require transplantation of human tumor cells into an immune compromised mouse, represent the current standard mouse model for cancer. Since the immune system plays an important role in tumor growth, progression and metastasis, the current standard mouse model is not ideal for accurate prediction of therapeutic effectiveness in patients.

Nanoparticles for the targeted treatment of infected cells

Current treatments for cancer and viral infection are limited remedies that often suppress cell or viral replication rather than eliminate diseased cells entirely from the body. A further limitation is that these therapies often compromise healthy cells as well, leaving problems of recurrence and side effects.

Researchers at developed a novel therapeutic nanoparticle (NP) system harboring therapeutic small siRNA that can significantly enhance effectiveness and specificity of treatments by killing diseased cells.

3D Image Rendering Software for Biological Tissues

Available for commercial development is software that provides automatic visualization of features inside biological image volumes in 3D. The software provides a simple and interactive visualization for the exploration of biological datasets through dataset-specific transfer functions and direct volume rendering. The method employs a K-Means++ clustering algorithm to classify a two-dimensional histogram created from the input volume. The classification process utilizes spatial and data properties from the volume.

Method for Targeted Therapeutic Delivery of Proteins into Cells

Current methods to deliver proteins into cells (e.g., using retrovirus, DNA transfection, protein transduction, microinjection, complexing the protein with lipids, etc.) have many shortcomings, such as lack of target specificity toxicity, or unwanted random integration into the host chromosome.  Protein transduction is an emerging technology for delivering proteins into cells by exploiting the ability of certain proteins to penetrate the cell membrane.  However, the majority of the proteins delivered by this means are usually trapped and subsequently degraded in the endosomes-lyso

Novel Anti-HIV Compounds Using Peptides or Peptide Mimetics

The subject invention describes a new class of compounds (such as peptides or mimetics) that target viral RNAs and inhibit the viral life cycle by blocking the viral recognition process. More specifically, these compounds are the first against an RNA Target - currently there are no clinical drugs against RNA targets in the treatment of any type of human disease.

Lentiviral Vectors with Dual Fluorescence/Luminescence Reporters

The National Cancer Institute’s Protein Expression Laboratory seeks parties to co-develop dual luminescent/fluorescent cancer biomarkers.

In research settings, visualization of  tumors or tumor cells is often done using either bioluminescence or fluorescence.  However, both of these methods have shortcomings: bioluminescence is not sensitive enough to sort individual tumor cells, and fluorescence cannot be used effectively to view internal tumors and is best used with surface tumors.
