The invention is directed to compositions and methods for selectively reducing the expression of a gene product from a desired target gene in a cell, as well as for treating diseases caused by the expression of the gene. More particularly, the invention is directed to compositions that contain double stranded RNA (“dsRNA”), and methods for preparing them, that are capable of reducing the expression of target genes in eukaryotic cells. The dsRNA has a first oligonucleotide sequence that is between 25 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of at least 19 nucleotides is sufficiently complementary to a nucleotide sequence of the RNA produced from the target gene to trigger the destruction of the target RNA by the RNAi machinery.

The HIV regulatory proteins Tat and Rev accumulate in nucleoli of human cells. No functional role has been attributed to this localization. Recently it was demonstrated that expression of Rev induces nucleolar re-localization of some nuclear factors involved in Rev export. Thus, it is likely that the nucleolus plays a critical role in Rev-mediated export of singly spliced and unspliced HIV-1 RNAs. As a test for trafficking of HIV-1 RNAs into the nucleolus, a hammerhead ribozyme which specifically cleaves HIV-1 RNA was joined to the U16 snoRNA resulting in accumulation of the ribozyme within nucleoli of human cells. Stably transduced human T-cells expressing this nucleolar localized ribozyme dramatically suppressed HIV-1 replication, confirming a possible trafficking of the HIV RNA through the nucleoli of human cells. In addition, a TAR element which binds Tat was joined to the U16 snoRNA, also resulting in localization in the nucleoli and inhibiting HIV replication.

摘要:
A method of diagnosing, assessing susceptibility, and/or treating schizophrenia involving the identification and/or observation of microRNAs (miRNA) and variant miRNA are provided. Micro RNAs alleles associated with schizophrenia and schizophrenia spectrum disorders were identified and ultra-rare variants in the precursor or mature miRNA were identified. Functional analyses of ectopically expressed copies of the variant miRNA precursors demonstrate loss of function, gain of function and altered expression levels. The present invention also provides methods for selecting a preferred therapy for a particular subject or group of subjects or individuals at risk for or suffering from schizophrenia or psychosis by use of miRNAs.
