  • RNA interference mediating small RNA molecules
    Patent number: 9567582
    Abstract: Double-stranded RNA (dsRNA) induces sequence-specific post-transcriptional gene silencing in many organisms by a process known as RNA interference (RNAi). Using a Drosophila in vitro system, we demonstrate that 19-23 nt short RNA fragments are the sequence-specific mediators of RNAi. The short interfering RNAs (siRNAs) are generated by an RNase III-like processing reaction from long dsRNA. Chemically synthesized siRNA duplexes with overhanging 3? ends mediate efficient target RNA cleavage in the lysate, and the cleavage site is located near the center of the region spanned by the guiding siRNA. Furthermore, we provide evidence that the direction of dsRNA processing determines whether sense or antisense target RNA can be cleaved by the produced siRNP complex.

  • gene in cancer and inflammation
    Patent number: 9556437
    Abstract: The present invention demonstrates for the first time that FAT1 plays an important role in modulating PDCD4 expression, which in turn regulates AP-1 dependent transcription, controls processes crucial for migration and invasion in cancer cells, controls induction of a pro-inflammatory micro environment in cancer cells. The study illustrates a link between inflammation and cancer in cells or in a subject. This work highlights the importance of FAT1 in the induction of the cellular pathways of migration and invasion, proteolysis of the ECM and the expression of pro-inflammatory molecules leading to a favorable micro environment for tumor and cancer progression.

  • Identification of novel genes coding for small temporal RNAs
    Patent number: 9550993
    Abstract: In Caenorhabditis elegans, lin-4 and let-7 enclode 22- and 21-nucleotide RNAs, respectively, that function as key regulators of developmental timing. Because the appearance of these short RNAs is regulated during development, they are also referred to as “small temporal RNAs” (stRNAs). We show that many more 21- and 22-nt expressed RNAs, termed microRNAs, (miRNAs), exist in invertebrates and vertebrates, and that some of these novel RNAs, similar to let-7 stRAN, are also highly conserved. This suggests that sequence-specific post-transcriptional regulatory mechanisms mediated by small RNAs are more general than previously appreciated.
