The Escherichia coli bacteriophage P1 encodes a site-specific recombinase called Cre and two 34-bp target sites of Cre recombinase called loxP. The Cre/loxP system has been used to achieve targeted insertion and precise deletion in many animal and plant genomes. The Cre/loxP system has particularly been used for the removal of selectable marker genes to create marker-free transgenic organisms. ...

Hydrophobic membrane proteins are cotranslationally targeted to the endoplasmic reticulum (ER) membrane, mediated by hydrophobic signal sequence. Mitochondrial membrane proteins escape this mechanism despite their hydrophobic character. We examined sorting of membrane proteins into the mitochondria, by using mitochondrial ATP-binding cassette (ABC) transporter isoform (ABC-me). In the absence o...

The CRISPR/Cas nuclease is becoming a major tool for targeted mutagenesis in eukaryotes by inducing double-strand breaks (DSBs) at pre-selected genomic sites that are repaired by non-homologous end joining (NHEJ) in an error-prone way. In plants, it could be demonstrated that the Cas9 nuclease is able to induce heritable mutations in Arabidopsis thaliana and rice. Gene targeting (GT) by homolog...

We synthesized a Yarrowia lipolytica strain overproducing lipase for industrial applications by using long terminal repeat (zeta) of the Y. lipolytica retrotransposon Ylt1 and an allele of URA3 with a promoter deletion to construct JMP3. JMP3 is a derivative of plasmid pHSS6 carrying a NotI-NotI cassette which contains a defective URA3 allele, a polylinker sequence, and the zeta region for targ...

Genome engineering methods in E. coli allow for easy to perform manipulations of the chromosome in vivo with the assistance of the λ-Red recombinase system. These methods generally rely on the insertion of an antibiotic resistance cassette followed by removal of the same cassette, resulting in a two-step procedure for genomic manipulations. Here we describe a method and plasmid system that can ...

Conditionally replicative adenovirus (CRAD) represents a promising approach for cancer therapy. Several CRADs controlled by the human telomerase reverse transcriptase promoter have been developed. However, because of their replicative capacity, the importance of cancer specificity for CRADs needs to be further emphasized. In this study, we have developed a novel dual-regulated CRAD, CNHK500-mE,...

Integrins mediate the adhesion of cells to each other and to the extracellular matrix during development, immunity, metastasis, thrombosis, and wound healing. Molecular defects in either the or subunit can disrupt integrin synthesis, assembly, and/or binding to adhesive ligands. This is exemplified by the bleeding disorder, Glanzmann thrombasthenia (GT), where abnormalities of the plateletspeci...

OBJECTIVE Complications of atherosclerotic cardiovascular disease due to elevated blood cholesterol levels are the major cause of death in the Western world. The liver X receptors, LXRalpha and LXRbeta (LXRs), are ligand-dependent transcription factors that act as cholesterol sensors and coordinately control transcription of genes involved in cholesterol and lipid homeostasis as well as macroph...

Foot and Mouth Disease (FMD) is highly contagious disease among cloven-hoofed animals. FMD virus has structural and non-structural proteins. Vp1 is the most immunogenic structural peptides of FMD virus, applied for major vaccine studies. Objective: Construction of Pet28-VP1 cassette for FMD virus type O/IRN/2010 and expression VP1 peptide as the most immunogenic antigen was the aim of this stud...
