摘要:
The invention generally relates to the prevention and/or treatment of cancer, and, more specifically, to the treatment of tumors, including solid tumors and their metastases, without radiation or standard chemotherapeutic agents. In one embodiment, the invention involves a method comprising: a) providing a subject with tumor cells, b) removing at least a portion of said tumor cells from said subject to create removed cells, c) treating at least a portion of said removed cells ex vivo, using stimulating agents, including thapsigargin and/or thapsigargin-related compounds, so as to create treated tumor cells; and d) introducing said treated tumor cells (or fragments thereof) in vivo into the same subject to generate anticancer therapeutic effects.

The invention provides methods and compositions for reducing or inhibiting net beta-amyloid peptide production and/or amyloid plaque formation. The methods and compositions involve administering a netrin-1 polypeptide or netrin-1 therapeutic to a subject in need thereof.
摘要:
In accordance with the present invention, it has been discovered that the β-amyloid precursor protein (APP), and two APP-like proteins (APLP1 and APLP2) are proteolytically cleaved by caspases in the C terminus to generate an approximately 31 amino acid peptide. It has been further discovered that the resultant C-terminal peptide is a potent inducer of apoptosis. Both caspase-cleaved APP and activated caspase-9 is present in brains of Alzheimer's disease patients but not in control brains. These findings indicate that caspase cleavage of APP and APP-like proteins leads to the generation of apoptotic peptides, which may contribute to the neuronal death associated with Alzheimer's disease. Accordingly, there are provided compositions and methods for modulating apoptosis.

The invention is directed to a method of modulating paraptotic cell death in a cell by contacting the cell with an effective amount of a compound selected from the group consisting of ceramide, Tumor Necrosis Factor (TNF), caspase-7, caspase-8, α-amino-3-hydroxy-5-methyl-4-isoxazole proprionic acid (AMPA), kainic acid and glutamic acid, wherein the effective amount of the compound induces paraptotic death of the cell. The invention further is directed to a method of inhibiting paraptotic cell death in a cell by contacting the cell with an effective amount of a compound selected from the group consisting of Alg-2-interacting protein 1 (AIP-1), Jun N-terminal kinase 1 (JNK1) neutralizing agent, Jun N-terminal kinase 2 (JNK2) neutralizing agent, TNF Receptor-Associated Factor 2 (TRAF2) neutralizing agent, ortho-phenanthroline and the JNK inhibitor SP 600125, wherein the effective amount of the compound inhibits paraptotic death of the cell.

摘要:
Methods for controlling cell death when the cell is exposed to one or more potentially lethal cellular insults. In one method, cell death is inhibited by introducing a reactive oxygen species limiter into the cell which prevents the build up of lethal levels of reactive oxygen species when the cell is exposed to a cellular insult. In another method, cell death is promoted in cancer cells or other proliferating cells which are naturally resistant to lethal cellular insults. The method involves neutralizing reactive oxygen species limiters, such as bcl-2, which occur naturally in cancer cells and which prevent the build up of reactive oxygen species within the cancer cells when they are exposed to lethal cellular insult. Neutralizing the reactive oxygen species limiter leaves the cancer cell unable to protect itself when cellular insult causes increases in the level of reactive oxygen species. The result is an increase in cell death.
摘要:
The invention provides compositions and methods for the treatment of mild cognitive impairment (MCI), and for inhibiting, reducing, delaying and/or preventing the progression of MCI to Alzheimer's disease. The methods entail administering an effective amount of one or more compounds selected from the group consisting of tropisetron, disulfuram, honokiol and nimetazepam. The methods also are useful for prophylactic and therapeutic treatment of amyloidogenic diseases, including Alzheimer's disease.

摘要:
This invention provides methods of reducing levels of amyloid beta (Aβ) protein and/or netrin-1 in a mammal. In certain embodiments the methods involve administering to the mammal a fragment of an amyloid precursor protein, or a mutant amyloid precursor protein, in an amount sufficient to decrease circulating levels of free Aβ protein in said mammal, wherein said fragment is a fragment of the extracellular domain of APP or a mutant thereof that binds amyloid beta protein and/or netrin-1.
