摘要:
Administration of a formulation comprising a antirestenotic compound conjugated to a microparticle carrier is effective to inhibit stenosis formation in a blood vessel. Such stenosis typically results, in the absence of treatment, from trauma to a vessel, such as an incision, excessive pressure, an angioplasty procedure and/or stent implantation. The antirestenotic compound is typically an antiproliferative, immunosuppressive, or antiinflammatory drug, such as rapamycin, tacrolimus, paclitaxel, dexamethasone, or an active analog or derivative, an antisense oligonucleotide, or combinations thereof. The microparticle carrier comprises a suspension of gas-filled microbubbles or biocompatible polymeric microparticles, in a pharmaceutically acceptable liquid vehicle, and is effective to deliver the conjugated therapeutic to the site of vessel injury.
摘要:
Microparticle carriers, particularly protein-encapsulated microbubbles, are used to deliver antiproliferative drugs to target sites in a subject. In particular, antirestenotic drugs are delivered to areas of vascular injury for treatment or prevention of hyperproliferative disease, e.g. stenosis, in blood vessels; and antineoplastic drugs are targeted to tumor sites.
摘要:
Provided herein are antisense oligonucleotides, compositions comprising antisense oligonucleotides, and methods for the use of antisense oligonucleotides in manipulating translation. Expression of isoforms of proteins expressed from different start codons of the same transcript are inhibited by antisense oligonucleotides, which may also enhance expression of non-target isoforms.

A method and compound for treating skeletal muscle mass deficiency in a human subject are disclosed. The composition is an oligomer of morpholino subunits and phosphorus-containing intersubunit linkages joining a morpholino nitrogen of one subunit to a 5′ exocyclic carbon of an adjacent subunit, contains between 10-40 nucleotide bases, has a base sequence effective to hybridize to an expression-sensitive region of processed or preprocessed human myostatin RNA transcript, identified, in its processed form, by SEQ ID NO:6, and is capable of uptake by target muscle cells in the subject. In practicing the method, the compound is administered in an amount and at a dosage schedule to produce an overall reduction in the level of serum myostatin measured in the patient, and preferably to bring the myostatin level within the a range determined for normal, healthy individuals.

摘要:
The present invention relates to antisense antiviral compounds and methods of their use and production in inhibition of growth of viruses of the Orthomyxoviridae family and in the treatment of a viral infection. The compounds are particularly useful in the treatment of influenza virus infection in a mammal. Exemplary antisense antiviral compounds are substantially uncharged, or partially positively charged, morpholino oligonucleotides having 1) a nuclease resistant backbone, 2) 12-40 nucleotide bases, and 3) a targeting sequence of at least 12 bases in length that hybridizes to a target region selected from the following: a) the 5′ or 3′ terminal 25 bases of the negative sense viral RNA segment of Influenzavirus A, Influenzavirus B and Influenzavirus C; b) the terminal 30 bases of the 5′ or 3′ terminus of the positive sense vcRNA; c) the 45 bases surrounding the AUG start codon of an influenza viral mRNA and; d) 50 bases surrounding the splice donor or acceptor sites of influenza mRNAs subject to alternative splicing.
摘要:
A method and composition for inducing human dendritic cells to a condition of reduced capacity for antigen-specific activation of T cells, and, in mature dendritic cells, increased production of extracellular IL-10 is disclosed. A population of dendritic cells is exposed to a substantially uncharged antisense compound, including partially positively charged, containing 12-40 subunits and a base sequence effective to hybridize to a target region within the sequence identified by SEQ ID NO:9, to form a duplex structure between the compound and transcript having a Tm of at least 45° C. Formation of the duplex blocks expression of full-length CD86 in the cells, which in turn leads to reduced capacity for antigen-specific activation of T cells, and, in mature dendritic cells, increased production of extracellular IL-10.

摘要:
A method and antisense compound for inhibiting the growth of pathogenic bacterial cells are disclosed. The compound contains no more than 12 nucleotide bases and has a targeting nucleic acid sequence of no fewer than 10 bases in length that is complementary to a target sequence containing or within 10 bases, in a downstream direction, of the translational start codon of a bacterial mRNA that encodes a bacterial protein essential for bacterial replication. The compound binds to a target mRNA with a Tm of between 50° to 60° C. The relatively short antisense compounds are substantially more active than conventional antisense compounds having a targeting base sequence of 15 or more bases.
摘要:
A method and conjugate for selectively killing antigen-activated T cells are disclosed. The conjugate is composed of a substantially uncharged antisense compound targeted against the human cFLIP protein, and a reverse TAT (rTAT) polypeptide coupled covalently to the antisense compound. The rTAT polypeptide is effective to produce selective uptake of the conjugate into antigen-activated T cells, relative to the uptake of the conjugate into non-activated T cells. The cFLIP antisense compound causes activation induced cell death (AICD) of activated lymphocytes. The method is useful in treating transplantation rejection and autoimmune conditions.
