摘要:
The present invention relates generally to a method of screening for a neoplastic cell in a subject. More particularly, the present invention provides a method of screening for both viable neoplastic cells and, still further, cytotoxin induced neoplastic cell death by detecting the level of expression of La protein and/or gene by a cellular population in said subject or in a biological sample derived from said subject. The method of the present invention is useful in a range of applications including, but not limited to, diagnosing, prognosing or assessing a neoplastic condition, monitoring the progression of such a condition, assessing the effectiveness of a therapeutic agent or therapeutic regime and predicting the likelihood of a subject either progressing to a more advanced disease state or entering a remissive state. The present invention also provides diagnostic agents useful for detecting La protein and/or nucleic acid molecules.
摘要:
The present invention relates generally to the fields of treatment, prophylaxis and diagnosis of cell-based and fibrotic conditions in animals including mammals. More particularly, the present invention contemplates the use of agents which modulate epithelial-mesenchymal transition (EMT) processes and mesenchymal-epithelial transition (MET) processes and hence are useful in the treatment of a range of conditions including inhibiting metastasis of solid tumors and the development of fibrosis, treating metastatic disease and in promoting wound healing. Diagnostic protocols to assess EMT and MET or its stage of development also form part of the present invention. The EMT and MET modulating agents are also useful in regulating gene expression and, hence, represent useful therapeutic and research tools.
摘要:
The present invention relates to isolated polypeptides which comprise a functional kinase domain comprising the amino acid sequence of the native human Abl kinase domain or an essentially similar sequence thereof in which at least one amino acid selected from Met244, Leu248, Gly250, Glu252, Tyr253, Val256, Glu258, Phe311, Ile313, Phe317, Met318, Met351, Glu355, Glu359, Ile360, His361, Leu370, Asp381, Phe382, His396, Ser417, Glu459 and Phe486 is replaced by another amino acid, said mutated functional kinase domain being resistant to inhibition of its tyrosine kinase activity by N-[4-methyl-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-phenyl]-4-(4-methyl-piperazin-1-yl m ethyl)-benzamide or a salt thereof, to the use of such polypeptides to screen for compounds which inhibit the tyrosine kinase activity of such polypeptides, to nucleic acid molecules encoding such polypeptides, to recombinant vectors and host cells comprising such nucleic acid molecules and to the use of such nucleic acid molecules in the production of such polypeptides for use in screening for compounds which inhibit the tyrosine kinase activity of such polypeptides.
摘要:
The present invention relates generally to a method of modulating the proinflammatory activity of C-reactive protein in endothelial cells. More particularly, the present invention relates to down-regulation of proinflammatory activity of C-reactive protein in vascular endothelial cells. Accordingly, the method of the present invention is useful, inter alia, in the treatment and/or prophylaxis of inflammatory conditions, particularly conditions characterised by proinflammatory activity of C-reactive protein in endothelial cells.
摘要:
The present invention relates generally to a method of modulating the growth of cells and, more particularly, to a method of down-regulating the growth of neoplastic cells. The present invention is useful, inter alia, in the therapeutic and/or prophylactic treatment of cancers such as, but not limited to, solid cancers such as cancers of the colon, stomach, lung, brain, bone, oesophagus, pancreas, breast, ovary or uterus.
摘要:
The present invention relates generally to a method of modulating endothelial cell activity and to agents useful for same. More particularly, the present invention relates to a method of modulating intercellular vascular endothelial permeability by modulating an intracellular protein kinase C-dependent signalling mechanism. The method for the present invention is useful, inter alia, in the treatment and/or prophylaxis of a condition characterised by aberrant, unwanted or otherwise inappropriate endothelial cell activity, in particular, conditions characterised by a loss of vascular integrity.
摘要:
A method of isolating a monoclonal antibody capable of inhibiting any one of IL-3, GM-CSF and IL-5 binding to the common receptor beta c, or a monoclonal antibody capable of inhibiting the cytokines binding to a receptor analogous to beta c. The method includes the steps of immunising an animal with a cytokine receptor or portion of a cytokine containing the critical binding site which portion includes the extracellular domain 4 or analogous domain in the analogous common receptor or part thereof. Antibodies producing cells from the animal are then isolated and fused with a myeloma cell line and then screened for a cell line that produces an antibody of the desired type. A monoclonal antibody, or fragments thereof capable of inhibiting the binding of the cytokines IL-3, GM-CSF and IL-5 to the beta c receptor, and a hybridoma cell line producing the antibody are also claimed.
摘要:
A chimeric GroEL protein is provided which includes a surface exposed exogenous amino acid sequence, which comprises an antigenic determinant of, for example, a pathogenic micro-organism. The exogenous amino acid sequence might be inserted into a hydrophilic region of the GroEL protein to provide a means of exhibiting the antigenic determinant to elicit an immune response specifically reactive to the antigenic determinant. This provides for a cellular bias to the elicited immune response and is thus is likely to be particularly useful for intracellular parasites.
