The invention relates to inhibitors of Sghrt and/or Gas5 lincRNAs, in particular to polynucleotides complementary to coding and non-coding sequences of said lincRNAs, and methods of producing said inhibitors. Also disclosed are the use of the afore agents to proliferate, regenerate or dedifferentiate a heart cell; methods for preventing and treating cardiac disease using the afore agents; and a prognostic or diagnostic assay to assess the regenerative or proliferative capacity of heart tissue before, after or during a cardiac treatment regimen, comprising determining the presence or amount of Sghrt and/or Gas5 lincRNAs. The present disclosure also relates to a method for screening for a therapeutic agent that can be used to treat or prevent a heart disorder, comprising analysing the functional expression and/or expression level of Sghrt and/or Gas5 lincRNAs in the presence and in the absence of the therapeutic agent.

Disclosed are methods and constructs for engineering circular RNA. Disclosed is a vector for making circular RNA, said vector comprising the following elements operably connected to each other and arranged in the following sequence: a.) a 5 homology arm, b.) a 3 group I intron fragment containing a 3 splice site dinucleotide, c.) optionally, a 5 spacer sequence, d.) a protein coding or noncoding region, e.) optionally, a 3 spacer sequence, f) a 5 Group I intron fragment containing a 5 splice site dinucleotide, and g.) a 3 homology arm, said vector allowing production of a circular RNA that is translatable or biologically active inside eukaryotic cells. In another embodiment, the vector can comprise the 5 spacer sequence, but not the 3 spacer sequence. In yet another embodiment, the vector can comprise the 3 spacer sequence, but not the 5 spacer sequence. Also disclosed is a method for purifying the circular RNA produced by the vector and the use of nucleoside modifications in circular RNA produced by the vector.

Described herein are methods and compositions useful in detecting, diagnosing and treating small cell lung cancer. Transgenic animal models and cell lines are disclosed for the study of a small cell lung cancer subtype. Methods of screening and identifying active agents for the treatment of a small cell lung cancer subtype as well as methods of identifying patients susceptible to treatment with aurora kinase inhibitors are also provided.

A mammalian cell comprising at least four distinct recombination target sites (RTS), an adenovirus (Ad) gene comprising E1A, E1B or a combination thereof, and a promoter operatively linked to the Ad gene, wherein the RTS, the Ad gene, and the promoter are chromosomally-integrated; methods for using the cell for generating a recombinant adeno-associated virus (rAAV) producer host cell; and methods for using the AAV producer host cell to produce, package and purify rAAV.

The present invention provides phagemid vectors and associated phagemid particles for cancer treatment, and in particular, to the use of novel phagemid particles and associated expression systems for the treatment, prevention, amelioration, or management of cancer. In particular, the invention relates to the use of phagemid particles and expression systems for the delivery of transgenes encoding cytokines, for the treatment, prevention, amelioration, or management of cancer. The invention also extends to the use of phagemid particles and expression systems for the delivery of transgenes, and for the combination of such treatment with the use of adoptively transferred T cells, for the treatment, prevention, amelioration, or management of cancer.

Compositions and methods are provided for modifying a genomic locus of interest in a eukaryotic cell, a mammalian cell, a human cell or a non-human mammalian cell using a large targeting vector (LTVEC) comprising various endogenous or exogenous nucleic acid sequences as described herein. Further methods combine the use of the LTVEC with a CRISPR/Cas system. Compositions and methods for generating a genetically modified non-human animal comprising one or more targeted genetic modifications in their germline are also provided.

The present invention relates to the production of avian induced pluripotent stem cells from non-pluripotent somatic cells, including embryonic fibroblasts and adult somatic cells. In this method, avian (including quail or chicken) somatic cells are reprogrammed into a state closely resembling embryonic stem cells including the expression of key stem cell markers alkaline phosphatase, etc. by transfecting/transducing the non-stem cells with genes (preferably using a non-integrating vector as otherwise described herein or alternatively an integrating vector, such a lentiviral vector, retroviral vector or inducible lentiviral vector, among others) which express at least nanog, Lin28 and cMyc. In preferred aspects of the invention, the transfected/transduced vectors express nanog, Lig28, cMyc, Oct 4 (POU5F1 or PouV), SOX2 and KLF4. The induced stem cells which are produced contribute to all 3 germ layers, the trophectoderm and in certain aspects, the gonad in chimeric offspring.

Methods of modulating expression of a target nucleic acid in a cell are provided including use of multiple orthogonal Cas9 proteins to simultaneously and independently regulate corresponding genes or simultaneously and independently edit corresponding genes.

The subject invention provides materials and method for making a recessive gene dominant. This is accomplished by interfering with the natural mechanisms that inhibit expression of the recessive gene and/or by interfering with the expression of the naturally dominant gene. In a preferred embodiment, the method of the subject invention comprises both reducing inhibition of expression of the recessive gene and increasing inhibition of the dominant gene.

Antigen binding proteins of the invention bind to Human Immunodeficiency Virus (HIV) envelope protein and are useful in treating and preventing HIV infection. In particular, the antigen binding proteins bind to two different epitopes on HIV envelope surface glycoprotein 120 (gp120): the V3 loop region and the CD4 binding site.
