Gluten is an important protein source for human beings and a wide diversity of foods has been developed to take advantage of this protein in wheat flour. However, some individuals, suffering from Celiac Disease (CD), cannot tolerate proline and glutamine-rich gluten peptides including γ-gliadins. A life-long gluten free diet is the only known effective treatment for such patients. However, the ...

Class 1 integrons play a role in the emergence of multi-resistant bacteria by facilitating the recruitment of gene cassettes encoding antibiotic resistance genes. 512 E. coli strains sourced from humans (n = 202), animals (n = 304) and the environment (n = 6) were screened for the presence of the intI1 gene. In 31/79 integron positive E. coli strains, the gene cassette regions could not be PCR ...

Conditional gene targeting uses the insertion of expression cassettes for the selection of targeted embryonic stem cells. The presence of these cassettes in the final targeted chromosomal locus may affect the normal expression of the targeted gene and produce interesting knock down phenotypes. We show here that the selection cassette may then be selectively removed in vivo, using three appropri...

Defining the contribution of acetylcholine to specific behaviors has been challenging, mainly because of the difficulty in generating suitable animal models of cholinergic dysfunction. We have recently shown that, by targeting the vesicular acetylcholine transporter (VAChT) gene, it is possible to generate genetically modified mice with cholinergic deficiency. Here we describe novel VAChT mutan...

CRISPR/Cas9 nucleases have enabled powerful, new genome editing capabilities; however, the preponderance of non-homologous end joining (NHEJ) mediated repair events over homology directed repair (HDR) in most cell types limits the ability to engineer precise changes in mammalian genomes. Here, we increase the efficiency of isolating precise HDR-mediated events in mouse embryonic stem (ES) cells...

Breast cancer is the most common type of cancer among females and the adenosine triphosphate (ATP) binding cassette E1 (ABCE1) gene is a member of the ATP‑binding cassette (ABC) family. Studies in lung cancer have shown that overexpression of ABCE1 in tumor cells promotes growth and inhibits apoptosis. However, little is known about whether the ABCE1 gene is associated with breast cancer. In th...

The adoptive transfer of engineered T cells for the treatment of cancer, autoimmunity, and infectious disease is a rapidly growing field that has shown great promise in recent clinical trials. Nuclease-driven genome editing provides a method in which to precisely target genetic changes to further enhance T cell function in vivo. We describe the development of a highly efficient method to genome...

Achondroplasia, the most common form of dwarfism in man, is a dominant genetic disorder caused by a point mutation (G380R) in the transmembrane region of fibroblast growth factor receptor 3 (FGFR3). We used gene targeting to introduce the human achondroplasia mutation into the murine FGFR3 gene. Heterozygotes for this point mutation that carried the neo cassette were normal whereas neo+ homozyg...

Exogenous protein expression in mammalian cells is necessary to produce therapeutic proteins and modern medical applications like developing DNA vaccines gene therapy. This study examines the human-Globin (hBG) second intron's capacity for intron-mediated enhancement (IME) various cell lines. Our study's main aim investigate effect of incorporation arrangement intron human Beta-globin into pVAX...

A new expression cassette (EC0) consisting of the fused 5' and 3' intergenic regions (IGRs) of the Eremothecium cymbalariae translational elongation factor 1α (EcTEF1) gene was evaluated through expression of the bacterial hygromycin B phosphotransferase (hph) resistance gene in the common baker's yeast Saccharomyces cerevisiae. Progressively shorter versions of the hph-containing EC cassette (...
