A trans-splicing ribozyme capable of splicing a rhodopsin transcript at a target splicing site and containing a sequence that is capable of complementarily binding to a target binding site of the rhodopsin transcript is disclosed. The trans-splicing ribozyme may further containing a desired rhodopsin transcript at 3′-end. The trans-splicing ribozyme may further contains an antisense sequence that is complementary to a region downstream the target binding site of the rhodopsin transcript. A nucleotide molecule encoding the trans-splicing ribozyme is also disclosed. Delivery systems to delivery the nucleotide molecule and/or the trans-splicing ribozyme to target tissue or cells as well as uses of the trans-splicing ribozyme, the nucleotide molecule, delivery systems, or pharmaceutical compositions containing any of them are also disclosed.

This disclosure relates to particles conjugated to therapeutic nucleic acids. In certain embodiments, the nucleic acid comprises a sequence that catalytically cleaves RNA, e.g., DNAzyme or RNAzyme. In certain embodiments, the particles contain nucleic acids with both DNAzyme and/or RNAzyme and siRNA sequences. The cleaving nucleic acids optionally comprise a sequence functioning to hybridize to a target of interest and/or the particles are further conjugated to a targeting moiety. In certain embodiments, conjugated particles are used in the treatment or prevention of cancer or viral infections or bacterial infections. In certain embodiments, conjugated particles are used in detecting metal ions and other small molecule analytes.

Novel processes and compositions are described which use viral capsid proteins resistant to hydrolases to prepare virus-like particles to enclose and subsequently isolate and purify target cargo molecules of interest including nucleic acids such as siRNAs and shRNAs, miRNAs, messenger RNAs, small peptides and bioactive molecules.

Modulators of intracellular chloride concentration for treating down syndrome The present invention relates to a modulator of a chloride transporter for use in the treatment of Down syndrome.

Disclosed are methods of treating chronic nervous system diseases or injuries, e.g., chronic spinal cord injury, using Nogo receptor antagonists, including Nogo receptor-1 (NgR1) polypeptides, Nogo receptor-1 antibodies and antigen-binding fragments thereof, soluble Nogo receptors and fusion proteins thereof, and polynucleotides. Also disclosed are methods of noninvasively monitoring axonal growth during and after treatment with an axonal growth promoting agent.

The present invention relates to a composition capable of preventing or treating cancer, particularly pancreatic cancer. The composition can effectively inhibit the growth or proliferation of cancer cells, and furthermore, effectively prevent the resistance of cancer cells to anticancer agents, or the metastasis or recurrence of cancer, by using an inhibitor of the activity of at least one of interleukin-10 receptor subunit beta (IL-10RB, IL-10R2) and interleukin-22 (IL-22); or an inhibitor of expression of a gene encoding at least one of the interleukin-10 receptor subunit beta and the interleukin-22.

The present invention aims to provide a pharmaceutical composition for transcolonic absorption capable of delivering a physiologically active substance (in particular, a water-soluble physiologically active substance of high molecular weight) having an intracellular site of action into specific tissue cells with high specificity, noninvasively by a means of administration other than injection. The pharmaceutical composition for transcolonic absorption of the present invention is characterized by comprising at least the following (a) and (b); (a) a physiologically active substance having an intracellular site of action and bound with an introduction substance into lipoprotein, and (b) a compound having an action of enhancing large intestinal mucosal epithelial permeability of the physiologically active substance.

The present invention relates to an inhibitor of necroptosis for use in preventing the metastasis of tumours. Further, the present invention relates to a method of preventing the metastasis of tumours by inhibiting necroptosis and to a method for modulating the transmigration of metastasising tumour cells through endothelium by modulating necroptosis as well as to an in-vitro method of identifying an inhibitor of necroptosis suitable as a lead compound and/or as a medicament for the prevention of tumour metastasis. Moreover, the present invention also relates to a method of identifying necroptotic and necrotic cells.

Compositions, devices, grafts and methods for reducing or preventing anti-neointima following cardiovascular injuries and interventions are disclosed. The compositions, devices, and grafts typically include an effective amount of a CTP synthase 1 inhibitor to reduce proliferation of vascular smooth muscle cells, without substantial reducing the proliferation of endothelial cells. Methods of reducing neointima formation, accelerating re-endothelialization, and reducing restenosis in a subject using the compositions, devices, and grafts are also disclosed.

Provided herein are antisense oligonucleotides that can effectively prevent or decrease c-myc protein expression as well as decrease overall rates of cell proliferation in in vitro and mammalian in vivo models of cell proliferative disorders as well as methods for using the same.
