Abstract:
Provided is an improved design of shRNA based on structural mimics of miR-451 precursors. These miR-451 shRNA mimics are channeled through a novel small RNA biogenesis pathway, require AGO2 catalysis and are processed by Drosha but are independent of DICER processing. This miRNA pathway feeds active elements only into Agog because of its unique catalytic activity. These data demonstrate that this newly identified small RNA biogenesis pathway can be exploited in vivo to produce active molecules.
Abstract:
A method for obtaining from genomic material genomic copy number information unaffected by amplification distortion, comprising obtaining segments of the genomic material, tagging the segments with substantially unique tags to generate tagged nucleic acid molecules, such that each tagged nucleic acid molecule comprises one segment of the genomic material and a tag, subjecting the tagged nucleic acid molecules to polymerase chain reaction (PCR) amplification, generating tag associated sequence reads by sequencing the product of the PCR reaction, assigning each tagged nucleic acid molecule to a location on a genome associated with the genomic material by mapping the subsequence of each tag associated sequence read corresponding to a segment of the genomic material to a location on the genome, and counting the number of tagged nucleic acid molecules assigned to the same location on the genome having a different tag, thereby obtaining genomic copy number information unaffected by amplification distortion.
Abstract:
The present invention provides methods of treating cognitive deficits associated with mental retardation. The methods comprise combining cognitive training protocols and a general administration of phosphodiesterase 4 inhibitors.
Abstract:
This disclosure relates to methods and compositions useful for treating Alzheimer's disease. In particular, the disclosure relates to pharmaceutical compositions containing an EGFR-inhibitory compound suitable for administration to treat Alzheimer's disease, as well as to related therapeutic methods. In addition, this disclosure relates to screening methods for identifying compounds useful for treating Alzheimer's disease based on the ability to inhibit the activity of EGFR.
Abstract:
Provided is a mosaic mouse model for use in determining the potency of an shRNA in vivo for reducing survival of cancer cells of chemotherapy-resistant leukemia. The syngeneic mouse recipient is transplanted with tet-on competent leukemia cells carrying a bicistronic nucleic acid construct comprising a promoter operably linked to a fusion gene associated with chemotherapy-resistant leukemia, and a sequence encoding a reverse tet-transactivator protein, such that both coding sequences are co-expressed from the promoter. Also provided are methods of treating soft tissue cancers.
Abstract:
The present invention provides methods of therapy of cognitive deficits associated with a central nervous system disorder or condition, methods of enhancing cognitive performance and methods for repeated stimulation of neuronal activity or a pattern of neuronal activity, such as that underlying a specific neuronal circuit(s). The methods comprise combining cognitive training protocols and a general administration of CREB pathway-enhancing agents.
Abstract:
Described herein are methods of screening drugs in a non-human animal using high resolution technology leading to generation of pharmacomaps. Further described herein are methods of predicting the therapeutic benefit and/or toxicity of drug candidate compounds. In specific embodiments, provided herein are methods of predicting the clinical effects of a test drug based on comparison of the pharmacomap of the test drug to the pharmacomap of one or more reference drugs with known clinical outcomes.
