Abstract:
Peptides, compositions and methods for modulating apoptosis, useful for treating diseases or disorders characterized by dysregulated apoptosis, such as cancer or neurodegenerative diseases. Screening methods for identifying agents that mediate apoptosis by regulating Atg12 binding to Bcl-2 family members.
Abstract:
Reversible pegylated drugs are provided by derivatization of free functional groups of the drug selected from amino, hydroxyl, mercapto, phosphate and/or carboxyl with groups sensitive to mild basic conditions such as 9-fluorenylmethoxycarbonyl (Fmoc) or 2-sulfo-9-fluorenylmethoxycarbonyl (FMS), to which group a PEG moiety is attached. In these pegylated drugs, the PEG moiety and the drug residue are not linked directly to each other, but rather both residues are linked to different positions of the scaffold Fmoc or FMS structure that is highly sensitive to bases and is removable under physiological conditions. The drugs are preferably drugs containing an amino group, most preferably peptides and proteins of low or medium molecular weight. Similar molecules are provided wherein a protein carrier or another polymer carrier replaces the PEG moiety.
Abstract:
An isolated polynucleotide is provided. The isolated polynucleotide comprising a nucleic acid sequence encoding a polypeptide of a Type II reaction center of a photosynthetic organism, the nucleic acid sequence being capable of imparting the type II reaction center with an activity under a temperature range different than that of the type II reaction center endogenous to the photosynthetic organism. Also provided are methods of using the sequences for generating photosynthetic organisms or tailor-made thermotolerance.
Abstract:
An article-of-manufacture is provided. The article-of-manufacture comprises a packaging material identified for treating cancer, packaging: (i) an anti-EGFR antibody comprising the CDR sequences of anti EGFR 565 (CNCM Deposit Number I-4262); and (ii) an anti-ErbB-2 antibody comprising the CDR sequences of anti ErbB-2 L431 (CNCM Deposit Number I-4115), anti ErbB-2 L26 (CNCM Deposit Number I-4113) or anti ErbB-2 N12 (CNCM Deposit Number I-4112), or (iii) an anti-EGFR antibody comprising the CDR sequences of anti EGFR 111 (CNCM Deposit Number I-4261); and (iv) an anti-ErbB-2 antibody comprising the CDR sequences of anti ErbB-2 L431 (CNCM Deposit Number I-4115). Also provided are pharmaceutical compositions and methods of using the above antibodies as well as other antibody combinations for the treatment of cancer.
Abstract:
A system and method for programming DNAzymes to be utilized as programmable drugs, which are active only in the presence of specific input combinations and/or certain conditions.
Abstract:
The present invention provides novel ruthenium based catalysts, and a process for preparing amines, by reacting a primary alcohol and ammonia in the presence of such catalysts, to generate the amine and water. According to the process of the invention, primary alcohols react directly with ammonia to produce primary amines and water in high yields and high turnover numbers. This reaction is catalyzed by novel ruthenium complexes, which are preferably composed of quinolinyl or acridinyl based pincer ligands.
Abstract:
Nucleic acid construct systems are disclosed capable of diagnosing and treating a cell state (e.g. disease state). Methods of diagnosing and treating disease states using the nucleic acid constructs described herein are also disclosed. In addition, methods of screening for agents capable of reversing a disease phenotype using the nucleic acid constructs of the present invention are disclosed.
Abstract:
A method of treating a disorder associated with pathological organ or tissue physiology or morphology is disclosed. The method is effected by transplanting into a subject in need thereof a therapeutically effective mammalian organ or tissue graft selected not substantially expressing or presenting at least one molecule capable of stimulating or enhancing an immune response in the subject.
Abstract:
Antibodies to Tumor Necrosis Factor receptors (TNF-Rs) which inhibit the cytocidal effect of TNF but not its binding to the TNF-Rs, and ligands interacting with other receptors of the TNF/NGF family, are provided together with methods of producing them. The antibodies preferably bind to the fourth cysteine rich domain of the p75 TNF receptor or to the region between said fourth cysteine rich domain and the cell membrane.
Abstract:
The invention relates to the use of an immunogen selected from the group consisting of (i) an anti-p53 mAb; (ii) a fragment of an anti-p53 mAb; (iii) a peptide based on a CDR of the heavy or light chain of an anti-p53 mAb, which peptide is capable of eliciting antibodies to p53; and (iv) a DNA molecule coding for the variable (V) region of an anti-p53 mAb in a suitable gene delivery vehicle, for the preparation of a pharmaceutical composition useful for induction of anti-tumor immunity in mammals, for activating an enhanced immune response to a p53 molecule in mammals, and/or for induction of immune responses to mutated and wild-type forms of a p53 in mammals. The use of anti-p53 mAbs and novel peptides based on the CDR2 and CDR3 of the heavy chains and CDR3 of the light chains of different anti-p53 mAbs are disclosed.
