摘要:
A method and comjugate for treating H. pylori infection in a subject are disclosed. The conjugate is composed of (a) a nuclease-resistant antisense oligomer effective to inhibit H. pylori infection in the subject by base-specific Watson-Crick binding to an H. pylori mRNA transcript, and (b) a transport moiety conjugated to the oligomer. The transport moiety is effective to facilitate uptake of the conjugate from the environment of the stomach into the cytoplasm of H. pylori cells by active transport or by pH-gradient transport across of the cell membrane of H. pylori. The conjugate is administered by oral route, preferably in a swellable polymer bolus designed to release the conjugate in sustained release.

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:
Provided are methods and antisense oligonucleotide analogs for suppressing an immune response in a mammalian subject, for the treatment or prevention of an autoimmune condition or transplantation rejection. The oligonucleotide analogs provided herein comprise a targeting sequence complementary to a preprocessed CTLA-4 mRNA region that spans the splice junction between intron 1 and exon 2 of the preprocessed CTLA-4 mRNA. Also provided are methods of use, in which the oligonucleotides are effective, when administered to a subject, to form within host cells, a heteroduplex structure (i) composed of the preprocessed CTLA-4 mRNA and the oligonucleotide compound, (ii) characterized by a Tm of dissociation of at least 45° C., and (iii) resulting in an increased ratio of processed mRNA encoding ligand-independent CTLA-4 to processed mRNA encoding full-length CTLA-4.
摘要:
A therapeutic oligomer-peptide conjugate, and methods of using the conjugate are disclosed. The conjugate includes (a) a substantially uncharged oligonucleotide analog compound having a base sequence that includes a string of bases that are complementary to four or more contiguous cytosine bases in a target nucleic acid region to which the compound is intended to bind, and (b) conjugated to the compound, an arginine-rich peptide effective to enhance the uptake of the compound into target cells. The string of bases in the compound includes at least one inosine base positioned in the string so as to limit the number of contiguous guanine bases in said string to three or fewer. The conjugate has greater cellular uptake than the compound alone, by virtue of the arginine-rich peptide, and substantially greater antisense activity greater activity than the conjugate in the absence of inosine-for guanine substitutions.
