摘要:
The present invention relates to RNAi agents, e.g., double stranded RNA (dsRNA) agents, targeting the Transmembrane protease, serine 6 (TMPRSS6) gene. The invention also relates to methods of using such RNAi agents to inhibit expression of a TMPRSS6 gene and to methods of preventing and treating a TMPRSS6-associated disorder, e.g., a disorder associated with iron overload and/or a disorder of ineffective erythropoiesis, e.g., hereditary hemochromatosis, β-thalassemia (e.g., β-thalassemia major and β-thalassemia intermedia), polycythemia vera, myelodysplastic syndrome, congenital dyserythropoietic anemias, pyruvate kinase deficiency, erythropoietic porphyria, Parkinson's Disease, Alzheimer's Disease or Friedreich's Ataxia.
摘要:
The present application pertains inter alia to an isolated vertebrate cell suitable for recombinant expression of a polypeptide of interest, wherein the vertebrate cell is altered to impair the function of the endogenous protease matriptase and wherein said cell comprises at least one heterologous polynucleotide encoding a polypeptide of interest and wherein the polypeptide of interest is secreted by the cell. It was found that using respective vertebrate cells for producing a recombinant polypeptide of interest significantly reduces clipping of the polypeptide of interest that is secreted into the cell culture medium. Also provided are improved production and screening methods.
摘要:
Disclosed herein are compositions and compounds comprising modified oligonucleotides for modulating TMPRSS6 and modulating an iron accumulation disease, disorder and/or condition in an individual in need thereof. Iron accumulation diseases in an individual such as polycythemia, hemochromatosis or β-thalassemia can be treated, ameliorated, delayed or prevented with the administration of antisense compounds targeted to TMPRSS6.
摘要:
Methods for identifying modified proteases with modified substrate specificity or other properties are provided. The methods screen candidate and modified proteases by contacting them with a substrate, such as a serpin, an alpha macroglobulins or a p35 family protein or modified serpins and modified p35 family members or modified alpha macroglobulins, that, upon cleavage of the substrate, traps the protease by forming a stable complex. Also provided are modified proteases.
摘要:
Provided are methods for and compounds for modulating the complement system. In particular, compounds are provided that inhibit complement activation and compounds are provided that promote complement activation. The compounds are therapeutics by virtue of their effects on the complement system. Hence, the compounds that inhibit complement activation can be used for treatment of ischemic and reperfusion disorders, including myocardial infarction and stroke, sepsis, autoimmune diseases, inflammatory diseases and diseases with an inflammatory component, including Alzheimer's Disease and other neurodegenerative disorders.
摘要:
Methods and compositions are provided for assessing, treating, and preventing diseases, especially cancer, using cancer-associated targets (CAT). Methods and compositions are also provided for determining or predicting the effectiveness of a treatment for these diseases or for selecting a treatment, using CAT. Methods and compositions are further provided for modulating cell function using CAT. Also provided are compositions that modulate CAT (e.g., antagonists or agonists), such as antibodies, proteins, small molecule compounds, and nucleic acid agents (e.g., RNAi and antisense agents), as well as pharmaceutical compositions thereof. Further provided are methods of screening for agents that modulate CAT, and agents identified by these screening methods.
摘要:
Novel splice variants as diagnostic markers, preferably membrane-bound. The novel variants according to the present invention may optionally be used for diagnosis of Marker-detectable disease as described herein, optionally through immunohistochemistry.
摘要:
Provided are MTSP-1 polypeptides modified to have altered activity and/or specificity so that they cleave a complement protein, such as complement protein C3, to inhibit its activity and thereby inhibit complement activation. The modified MTSP-1 polypeptides that inhibit complement activation can be used for treatment of diseases and conditions in which complement activation plays a role. Such diseases and conditions include inflammatory diseases and diseases with an inflammatory component. Exemplary of these disorders are ischemic and reperfusion disorders, including myocardial infarction and stroke, sepsis, autoimmune diseases, ophthalmic disorders, such as diabetic retinopathies and macular degeneration, including age-related macular degeneration (AMD), and transplanted organ rejection, such as renal delayed graft function (DGF).
