Cancer Therapeutic Based on Hypoxia Inducible Factor 1 (HIF-1) Inhibitors

Hypoxia is a characteristic of many solid tumors resulting from accelerated cellular proliferation and inadequate vascularization. HIF-1 is a transcription factor critical for maintaining cellular homeostasis in, and adaptively responding to, low oxygen environments. HIF-1 becomes activated through binding to the transcriptional co-activator protein p300. Disruption of the HIF-1/p300 interaction could potentially modulate HIF-1 activity.

Methods for Selection of Cancer Patients and Predicting Efficacy of Combination Therapy

Available for licensing from the Laboratory of Cancer Biology and Genetics of the National Cancer Institute (NCI) is a novel gene signature of thirty-seven drug-responsive genes that links changes in gene expression to the clinically desirable outcome of improved overall survival. Expression of these genes has been linked to prognosis in several cancers, including, but not limited to: multiple myeloma, melanoma, and lung and breast cancers.

SIRT2 Inhibitors as Novel Therapeutics for Myocardial Infarction and Ischemic Stroke and to Prevent Necrosis

Sirtuin 2 (SIRT2) inhibitors to reduce necrosis and, thereby, as novel therapeutics to treat ischemic stroke and myocardial infarction. Accumulating evidence indicates that programmed necrosis plays a critical role in cell death during ischemia-reperfusion. NIH investigators have shown that the NAD-dependent deacetylase SIRT2 binds constitutively to receptor-interacting protein 3 (RIP3) and that deletion or knockdown of SIRT2 prevents formation of the RIP1-RIP3 complex in mice.

Human T Cell Line Chronically Infected With HIV

A stable line of human T cells (ACH-2) was developed in which cells infected chronically with the AIDS virus (HIV) remained nonproductive prior to exposure to phorbol esters or human cytokines. This situation mimics the latent state of HIV and the development of AIDS in humans and indicates that the full-blown disease may be triggered by cellular-derived substances (e.g., cytokines). This is the first description of such a cell line.

Conjugate Vaccine for Neisseria Meningitidis

The invention discloses a vaccine which comprises lipooligosaccharide (LOS) isolated from N. meningitidis and conjugated to a carrier protein. The invention also discloses a method of making the acellular vaccine. The method consists of two main steps. In the first step the lipooligosaccharide (LOS), chosen so it does not contain the lacto-N-neotetraose human antigen (LNnT), is detoxified by a novel procedure which uses hydrazine to remove the O-linked fatty acids. In the second step, the detoxified LOS (dLOS) is covalently conjugated to a carrier protein such as Tetanus Toxoid (TT).

Treatment and Prevention of Inflammatory Bowel Disease (IBD) using Mutant and Chimeric IL-13 Molecules

Ulcerative colitis (UC) is a chronic inflammatory disease of the colorectum and affects approximately 400,000 people in the United States. The cause of UC is not known, although an abnormal immunological response to bacterial antigens in the gut microflora is thought to be involved. Present treatments for UC include anti-inflammatory therapy using aminosalicylates or corticosteroids, as well as immunomodulators and diet.

Collagen-Induced Platelet Aggregation Inhibitor from Mosquito Salivary Glands

Exposed collagen in injured blood vessels provides a substrate for platelets to adhere and aggregate initiating the first step in thrombosis, the formation of blood clots inside a blood vessel. Despite the essential role of platelets in vascular injury, excessive platelet aggregation may also result in thrombotic diseases such as stroke and heart attack.

Monoclonal Antibodies Against Poliovirus

Early work by Hammond at al. showed gamma globulin to be effective for the prevention of poliomyelitis. Therefore, passive immunotherapy could be another way to treat chronic excretors. Even though prior attempts to use intravenous immunoglobulin (IVIG) and breast milk were unsuccessful, there is reason to think that higher doses of antipoliovirus antibodies could result in complete clearance of poliovirus from chronically infected individuals.

Novel Small Molecule Agonists of the Relaxin Receptor as Potential Therapy for Heart Failure and Fibrosis

The present invention is directed to novel small molecule agonists of the mammalian relaxin family receptor 1 (RXFP1), including human RXFP1. Activation of RXFP1 induces: 1) vasodilation due to up-regulation of the endothelin system; 2) extracellular matrix remodeling; 3) moderation of inflammation by reducing levels of inflammatory cytokines; and 4) angiogenesis. Small molecule agonists of RXFP1 may be useful in treating acute heart failure (AHF), scleroderma, fibrosis, other conditions associated with the biology of relaxin, and in improving reproductive health and wound healing.
