Abstract:
Methods and compositions are provided for generating novel nucleic acid molecules through targeted spliceosome mediated RNA trans -splicing (SMaRT TM ) that result in expression of a splicing isoform or variant thereof. The methods and compositions are based upon pre-trans-splicing molecules (PTMs) designed to interact with a target pre-mRNA molecule and mediate a t rans -splicing reaction generating a novel chimeric RNA molecule encoding a splicing isoform for the treatment of a variety of gene isoform induced diseases such as cancer.

También se refiere a una composición farmacéutica que comprenda dichas nanopartículas y a su uso para la elaboración de un medicamento para la prevención y/o el tratamiento de una enfermedad que cursa con una deficiencia de mucinas.
Abstract:
The disclosure relates generally to genetic manipulation of stem and primary cells and to reprogramming of somatic cells, more specifically, human cells. In particular, compositions and methods are disclosed for the generation and maintenance of such engineered cells.
Abstract:
Human somatic cells are reprogrammed to become induced pluripotent stem cells (iPS cells) by the introduction of a minicircle DNA vector. Cells of interest include adipose stem cells.
Abstract:
The disclosure relates to a method of reprogrammlng one or more somatic cells, e.g., partially differentiated or fully/terminally differentiated somatic cells, to a less differentiated state, e.g., a pluripotent or multipotent state. In further embodiments the invention also relates to reprogrammed somatic cells produced by methods of the invention, to chimeric animals comprising reprogrammed somatic cells of the invention, to uses of said cells, and to methods for identifying agents useful for reprogramming somatic cells.
Abstract:
Methods and composition of induction of pluripotent stem cells and other desired cell types are disclosed. For example, in certain aspects methods for generating essentially vector-free induced pluripotent stem cells are described. Furthermore, the invention provides induced pluripotent stem cells and desired cell types essentially free of exogenous vector elements with the episomal expression vectors to express differentiation programming factors.
Abstract:
An integration-defective retroviral vector transfer cassette lacking a functional polypurine tract (PPT) is provided. Also provided are isolated nucleic acids that include a heterologous nucleotide sequence, one or two retroviral long terminal repeats (LTRs), a packaging signal, a rev responsive element, and a eukaryotic promoter, wherein the nucleic acid lacks a functional PPT; vectors that include the disclosed isolated nucleic acids; recombinant retroviral particles and mRNAs thereof; retroviral vector kits; and methods for producing integration-defective vector particles, achieving gene expression of a nucleotide sequence of interest, and inserting a nucleotide sequence of interest into a host cell genome in a site-specific or non-specific manner.
Abstract:
The invention relates to a vector comprising an origin of replication for episomal maintenance in a metazoan cell, a gene for episomal maintenance in the metazoan cell, and a telomeric polynucleotide sequence. The vector can be used for episomal expression of RNA and polypeptides in metazoan cells.
Abstract:
This invention provides methods of reducing a replication of a gammaherpesvirus genome, treating a KSHV infection, and treating or reducing an incidence of a KSHV-associated disease, comprising contacting a subject with a composition that inhibits initiation of DNA replication from a region of a genome of a gammaherpesvirus. The invention also provides isolated DNA molecules capable of episomal replication in a eukaryotic cell, and methods of delivering a recombinant protein or therapeutic RNA molecule, comprising same.
Abstract:
Recombinant expression vectors are provided comprising a 3' UTR of a light chain and an Epstein-Barr virus origin of replication. Also provided are host cells comprising such vectors and methods of producing recombinant protein with such vectors. Additional methods of producing a recombinant protein involve contacting cells with a first and second vector, each of which encode a different polypeptide chain, and wherein the second vector is present in an amount which is about 1.5 to 2.5 times as much as that of the first vector. Cells also can be transfected with a recombinant transient expression vector encoding a protein and are cultured in a medium in a membrane-enhanced culturing vessel to produce recombinant protein.
