Abstract:
The disclosure features a variety of compositions and methods for modulating an interaction between MUC1 and caspase-8 and/or an interaction between MUC1 and a DED-containing protein (e.g., an anti-apoptotic DED-containing protein or a pro-apoptotic DED-containing protein). Such methods and compositions are useful for the treatment or prevention of e.g., a variety of pathological disorders characterized by elevated or decreased levels of apoptosis. Moreover, the compositions and methods are also useful to identify, design, and generate compounds that modulate the interactions. The compounds and/or pharmaceutical compositions containing the compounds can be used in the treatment of disease.
Abstract:
The present invention is directed to antibodies binding to the MUC1 cytoplasmic domain and methods of using such antibodies to treat, diagnose, detect and monitor cancers that express the MUC1 antigen.
Abstract:
Methods for improved administration and dosing of DPD inhibitors in combination with 5-FU and/or 5-FU prodrugs are provided, comprising first administering to a patient in need thereof a DPD inhibitor that substantially eliminates activity of the enzyme and thereafter administering 5-FU or a 5-FU prodrug, wherein the level of 5-FU or 5-FU prodrug is in substantial excess of DPD inhibitor in the patient.
Abstract:
This invention relates to regulation of cell signaling, cell growth, and more particularly to the regulation of cancer or immune cell growth. The invention provides methods of inhibiting interactions between MUC1 and BH3-containing proapoptotic proteins, methods of inhibiting MUC1 expression, and methods of promoting apoptosis. Also provided are screening methods for compounds that inhibit interactions between MUC1 and BH3-containing proapoptotic proteins and pharmaceutical compositions of the same.
Abstract:
The invention provides for peptides from the MUC1 cytoplasmic domain and methods of use therefor. These peptides can inhibit MUC1 oligomerization, thereby preventing tumor cell growth, inducing tumor cell apoptosis and necrosis of tumor tissue in vivo.
Abstract:
The present disclosure demonstrates the successful use of constitutive promoters operatively linked to genes encoding radiosensitizing or radioprotecting factors, administered to cells, tissues, or patients in conjunction with radiation exposure. Also disclosed are pharmacological preparations to be used to increase the levels of radiosensitizing compounds such as TNF-α, or radioprotective compounds such as MnSOD, in specified tissues or tumors of a subject.
Abstract:
Treatment of cells with ionizing radiation is associated with the production of arachidonic acid. Inhibition of phospholipase A2 abolishes radiation-mediated arachidonate production, protein kinase C induction and tumor necrosis factor gene expression. The addition of inhibitors of lipoxygenase, such as ketoconazole, prior to irradiation reduces the expression of of tumor necrosis factor while maintaining the expression of other radiation inducible genes, such as Egr-1 and c-jun. In contrast, indomethacin, an inhibitor of cyclooxygenase, enhanced the expression of tumor necrosis factor as well as other radiation inducible genes. The results show that lipoxygenase inhibitors are useful in the treatment of radiation-induced mucositis, dermatitis, pneumonitis, proctitis, and esophagitis. which may be due to the production of cytokines such as TNF.
Abstract:
The present invention is directed to improved compositions for cellular delivery of peptides. Using segments of only 3-5 positively-charged residues, one can effectively transfer peptides, including therapeutic peptides, into cells. Also provided are modified peptides such as those include stapled and cyclized peptide technology, as well as peptoids/peptidomimetics.
Abstract:
The invention provides methods of identifying and making compounds that inhibit the interaction between MUC1 and either or both of HSP70 and HSP90. Also embraced by the invention are in vivo and in vitro methods of inhibiting such an interaction.
Abstract:
The invention provides methods of identifying and making compounds that inhibit the interaction between MUC1 and either p53 or TBP. Also embraced by the invention are in vivo and in vitro methods of inhibiting such an interaction and of inhibiting the expression of MUC1 by a cell.
