Abstract: A transgenic insect cell line for production of elevated levels of recombinant glycoproteins comprising mammalian-like N-glycans is provided. Also disclosed are nucleic acid sequences encoding ?-N-acetylglucosaminidases.
Abstract: A non-immunogenic selection epitope may be generated by removing certain amino acid sequences of the protein. For example, a gene encoding a truncated human epidermal growth factor receptor polypeptide (EGFRt) that lacks the membrane distal EGF-binding domain and the cytoplasmic signaling tail, but retains an extracellular epitope recognized by an anti-EGFR antibody is provided. Cells may be genetically modified to express EGFRt and then purified without the immunoactivity that would accompany the use of full-length EGFR immunoactivity. Through flow cytometric analysis, EGFRt was successfully utilized as an in vivo tracking marker for genetically modified human T cell engraftment in mice. Furthermore, EGFRt was demonstrated to have cellular depletion potential through cetuximab mediated antibody dependent cellular cytotoxicity (ADCC) pathways.
Abstract: Hepatitis C reporter viruses containing Core through NS2 of prototype isolates of all major HCV genotypes and the remaining genes of isolate JFH1, by insertion of reporter genes in domain III of HCV NS5A were developed. A deletion upstream of the inserted reporter gene sequence conferred favorable growth kinetics in Huh7.5 cells to these viruses. These reporter viruses can be used for high throughput analysis of drug and vaccine candidates as well as patient samples. JFH1-based intergenotypic recombinants with genotype specific homotypic 5?UTR, or heterotypic 5?UTR (either of genotype 1a (strain H77) or of genotype 3a (strain S52)) were also developed. The present inventors additionally developed J6/JFH1 recombinants with the 5?UTR of genotypes 1-6. These recombinants with different 5?UTRs are a useful to study the function of the 5?UTR in a genotype specific manner.

Abstract: A method of ex-vivo increasing insulin content in progenitor cells which express SLUG is provided. The method comprises downregulating an amount or activity of SLUG in the progenitor cells. Cell populations generated thereby and uses thereof are also provided.
Abstract: This invention relates to the novel identification of arginase as an enzymatic activity which can reverse inhibition of neuronal regeneration in the central and peripheral nervous system. Assays to monitor the effects of various agents on arginase expression and thus on neuronal regeneration and repair and to identify agents which will block or promote the inhibitory effects on neuronal outgrowth are provided. This invention also relates to compositions and methods using agents that can reverse the inhibitory effects of myelin on neural regeneration by affecting arginase activity or putrescine and derivative polyamine levels in a neuron.

Abstract: The present disclosure provides adeno-associated virus (AAV) virions with altered capsid protein, where the AAV virions exhibit greater infectivity of retinal cells compared to wild-type AAV. The present disclosure further provides methods of delivering a gene product to a retinal cell in an individual, and methods of treating ocular disease.

Abstract: Reconstituted human breast tumor models are disclosed. The models, which are incorporated into mice, provide actual tumors that arise spontaneously, thereby mimicking naturally occurring breast cancer. The tumors are genetically human, because they arise from human mammary tissues that develop from human mammary epithelial cells implanted into host mice. Prior to implantation, the mammary epithelial cells are genetically modified to contain either: (a) a recombinant human oncogene and an SV40er; or (b) a recombinant human oncogene, a transgene or shRNA that inhibits the p53 pathway, and a transgene or shRNA that inhibits the Rb pathway.
