Abstract:
The present invention is directed to a system to significantly increase the expression of genes of interest, and in particular proteins and polypeptide products. Expression of hantavirus nucleocapsid protein (N) by itself results in augmented translational expression of diverse genes. The mechanism of this augmentation relies on the ability of N to replace the cellular cap binding complex to attain more efficient translation initiation- the result being great mRNA production and greater protein/polypeptide production. The inventors have also recently found that inclusion of a 5' untranslated leader region (viral UTR) from a viral RNA, in conjunction with N, leads to even more robust expression. This mechanism appears to involve recognition of the viral UTR by the N to provide even more robust protein production. Thus, a general strategy for expression of any gene would be to generate significant quantities of mRNA containing the viral UTR from a strong promoter, and then to allow translation of mRNA of a gene product in the presence of N. Even a modest increase in the production of commercially desirable proteins is a goal in industry.
Abstract:
Isolated polypeptides, nucleic acids, and methods relating to cellular internalization of materials are described herein. Generally, the isolated polypeptides include a membrane transduction domain of human tissue factor pathway inhibitor-2 (TFPI-2). In some cases, the isolated polypeptide can be a fusion peptide that includes a membrane transduction domain of human TFPI-2 and a heterologous peptide domain. The nucleic acids include nucleic acids that encode the isolated polypeptides described herein. The methods generally include providing a composition that includes a membrane transduction domain of human TFPI-2 coupled to a material, and contacting the composition with a cell under conditions effective to permit the cell to internalize the composition.
Abstract:
A method of treatment and/or prevention of cancer comprises administering agents which cause increased intracellular granularity in cancer cells, at least in an amount sufficient to inhibit proliferation of such cells and preferably in an amount sufficient to lead to cancer cell death. The method is particularly directed to refractory cancer, particularly hormone refractory prostate cancer. The agents identified cause increased intracellular granularity in the cancer cells, and also convert adherent cancer cells to non-adherent cancer cells, leading to cancer cell death. Using the present invention, cancer cells undergo increased intracellular granularity at relatively low agent concentrations, while also inhibiting cell proliferation. Increased concentrations lead to conversion of adherent cancer cells to non-adherent cancer cells, then to cell death. While the exact mechanism of cancer cell degradation and death is not completely understood, the treated cancer cells, including refractory prostate cancer cells, give indications of cell death through an autophagic mechanism. Pharmaceutical compositions related to the presently disclosed methods are also disclosed.
Abstract:
A simple, fast, selective and highly sensitive electrochemical method assay and disposable device for detection of viruses, bacteria, proteins, DNA, and/or organic/inorganic compounds. The sensor has a multi-layered construction, with each successive layer performing a different function. The design further allows for the packing of numerous microscopic electrode transducers onto the small footprint of a biochip device, allowing for a high-density array of sensors.
Abstract:
The present invention relates to the use of suppressive macrophage or dendritic cells (activated with C-reactive protein or CRP-related compounds), for the treatment of various disease states and conditions associated with immune thrombocytopenic purpura (ITP) and/or systemic lupus erythematosus (SLE), including lupus of the skin (discoid), systemic lupus of the joints, lungs and kidneys, hematological conditions including hemolytic anemia and low lymphocyte counts, lymphadenopathy and CNS effects, including memory loss, seizures and psychosis, among numerous others as otherwise disclosed herein. In another aspect of the invention, the reduction in the likelihood that a patient who is at risk for an outbreak of a disease state or condition associated with systemic lupus erythematosus or ITP will have an outbreak is an additional aspect of the present invention. In the case of ITP, methods of the present invention are used to increase platelet counts in the treated patient. In addition, in the case of ITP, the present invention relates to the use of CRP or a CRP-related compound in the absence of suppressive macrophages for the treatment of ITP.
Abstract:
The present invention comprises a dry powder inhaler (DPI) that uses a patient's inhalation flow to concentrate energy in an aeroelastic element for deaggregation and dispersion of a powder dose. The result is a DPI that delivers a dose independent of inspiratory abilities of the patient, solving a major problem of conventional DPIs. Increased tension on the aeroelastic element causes higher frequency vibrations and improved powder dispersion. The tension of the aeroelastic element can be modified prior to dispensing the DPI to the patient, allowing for individualization for single patients or groups of patients. In addition, the DPI has features that increase the turbulence of the airflow as it passes through the device, further increasing the dispersion and deaggregation of the powder. The DPI can hold a single dose or multiple doses. The powder doses can be dispensed directly onto the aeroelastic element, or may be in adjacent blister packaging.
Abstract:
The invention is directed to virus-like particles (VLPs)of an RNA bacteriophage that (a) comprises a coat polypeptide of said phage modified by insertion of a heterologous peptide that is displayed on said VLP and (b) encapsidates said bacteriophage mRNA as well as populations of these VLPs, and their uses. The invention is further directed to VLPs that encapsidate heterologous substances, as well as populations of these VLPs and their uses.
Abstract:
The current invention is in the field of molecular biology/pharmacology and provides compounds which modulate the effects of GPR30 as well as the classical estrogen receptors alpha and beta (ERa and ERß). These compounds may function as agonists and/or antagonists of one or more of the disclosed estrogen receptors. Diseases which are mediated through one or more of these receptors include cancer (particularly breast, reproductive and other hormone-dependent cancers, leukemia, colon cancer, prostate cancer), reproductive (genito-urological) including endometreitis, prostatitis, polycystic ovarian syndrome, bladder control, hormone-related disorders, hearing disorders, cardiovascular conditions including hot flashes and profuse sweating, hypertension, stroke, obesity, osteoporosis, hematologic diseases, vascular diseases or conditions such as venous thrombosis, atherosclerosis, among numerous others and disorders of the central and peripheral nervous system, including depression, insomnia, anxiety, multiple sclerosis, neuropathy, neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease, as well as inflammatory bowel disease, Crohn's disease, coeliac (celiac) disease and related disorders of the intestine. A contraceptive indication to prevent or reduce the likelihood of pregnancy after intercourse is a further aspect of the present invention.
Abstract:
The present invention relates to the use of C-reactive protein, its mutants, metabolites and polypeptides and related compounds thereof for the treatment of various disease states and conditions associated with systemic lupus erythematosus (SLE), including lupus of the skin (discoid), systemic lupus of the joints, lungs and kidneys, hematological conditions including hemolytic anemia and low lymphocyte counts, lymphadenopathy and CNS effects, including memory loss, seizures and psychosis, among numerous others as otherwise disclosed herein, hi another aspect of the invention, the reduction in the likelihood that a patient who is at risk for an outbreak of a disease state or condition associated with systemic lupus erythematosus will have an outbreak is an additional aspect of the present invention.
Abstract:
A butterfly needle assembly has a needle and a shield with wings integral to either the needle or the shield. The wings have aesthetically pleasing patterns to distract the patient during treatment. The mechanical design of the needle and shield juncture improves the stability of the assembly when inserted into a patient, as well as allowing the assembly to be disengaged with a single hand to help the caregiver avoid a needle "stick" and prevent the spread of diseases.
