A Tet-Regulated Mouse Model for Cataract

Cataract is the most common cause of blindness worldwide, with an estimated 25 million blind and 119 million visually impaired individuals worldwide. Over 20 million adults in the US alone are currently diagnosed with cataracts making this disease a major health concern. The incidence of cataract increases with age and a number of etiologic factors have been proposed in the pathogenesis of age-related cataract in humans including genetic factors, environmental factors and metabolic and biochemical changes in the crystalline lens.

Phenylthiocarbamide (PTC) Taste Receptor

Bitter taste has evolved in mammals as a central warning signal against ingestion of poisonous or toxic compounds. However, many beneficial compounds are also bitter and taste masking of bitter tasting pharmaceutical compounds is a billion dollar industry. The diversity of compounds that elicit bitter-taste sensations is vast and more than two dozen members of the TAS2R bitter taste receptor gene family have been identified.

Regulation of RNA Stability

This invention relates to the discovery that tristetraprolin (TTP) can promote the poly(A)RNase (PARN) mediated deadenylation of polyadenylated substrates containing AU-rich elements (AREs). As one aspect of the invention, the inventors have developed a cell free system that may be used for the purposes of assessing the effects of the various system components or their derivatives (i.e. AREs, PARN, or TTP) on the deadenylation process or the effects of various test agents on the deadenylation process.

Pain Control by the Selective Local Ablation of Nociceptive Neurons

The vanilloid receptor (VR) is a cation channel predominantly expressed on the peripheral processes and perikarya of nociceptive primary afferent neurons. Previous studies have shown that activation of the peripheral receptors by agonists such as capsaicin from hot peppers, or the much more potent resiniferatoxin, produces acute pain sensation which may be followed by desensitization. These inventors discovered that administration of VR agonists in the vicinity of neuronal cell bodies expressing the VR receptor can actually destroy those cells.

IL-21 Critically Regulates Immunoglobulin Production

The invention includes a mouse in which the IL-21 receptor gene is disrupted by homologous recombination, the disruption being sufficient to prevent expression of the IL-21 receptor and thus to inhibit the action of IL-21. The invention also includes a mouse in which both the IL-21 receptor gene and the IL-4 gene are simultaneously disrupted in fashions being sufficient to inhibit the action of IL-21 and the production of IL-4. In a homozygous state, these mutations produce a mouse that has diminished B cell function.

Activation of Recombinant Diphtheria Toxin Fusion Proteins by Specific Proteases Highly Expressed on the Surface of Tumor Cells

This invention relates to diphtheria toxin fusion proteins comprising a diphtheria toxin (DT) cell-killing component and a cell-binding component such as granulocyte macrophage colony-stimulating factor (GM-CSF), interleukin 2 (IL-2), or epidermal growth factor (EGF). Receptors for the latter three materials are present on many types of cancer cells; therefore, these fusion proteins bind preferentially to these cancer cells. A key feature is that these toxins are altered so as to require activation by a cell-surface protease that is overexpressed on many types of cancers.

Multipotent Postnatal Stem Cells From Human Periodontal Ligament and Uses Thereof

It is estimated that over 40 percent of the adult population in the United States has periodontal disease in one form or another. Periodontal Disease is a chronic infection of the periodontal ligament (PDL) and the adjacent bone and cementum. The effects of Periodontal Disease range from simple gum inflammation to, in extreme cases, tooth loss.

Method for the Treatment of Multiple Sclerosis

The invention relates to the discovery that humanized antibodies to the interleukin-2 receptor (IL-2R) such as (daclizumab) are effective in treating multiple sclerosis (MS). In particular, it has been discovered that patients who have failed to respond to therapy with interferon-beta show dramatic improvement when treated with daclizumab, with patients showing both a reduction in the total number of lesions and cessation of appearance of new lesions during the treatment period. Daclizumab is effective both in combination with interferon-beta and alone.

Modulators of Nuclear Hormone Receptor Activity: Novel Compounds, Diverse Applications for Infectious Diseases, Including Anthrax (<i>B. anthracis</i>)

Nuclear hormones such as glucocorticoids dampen inflammatory responses, and thus provide protection to mammals against inflammatory disease and septic shock. The Anthrax lethal factor represses nuclear hormone receptor activity, and thus may contribute to the infectious agent causing even more damage to the host. This observation can be exploited to find new means of studying and interfering with the normal function of nuclear hormone receptors.

Hybrid Adeno-Retroviral Vector for the Transformation of Cells (E-258-1998)

The invention described and claimed in this patent application provides for novel hybrid vectors which may be used for cell transformation, either in vivo or in vitro. The hybrid vectors have an adenoviral backbone with retroviral long terminal repeats (LTRs). Such vectors are capable of transforming dividing or non-dividing cells and integrate stably into the chromosome providing a means of efficient, reliable, long-term gene expression. The vector was packaged as a recombinant adenovirus and delivered to the target cell.
