The identification and significance of cancer stem-like cells in malignant gliomas remains controversial. It has been proposed that cancer stem-like cells display increased drug resistance, through the expression of ATP-binding cassette transporters that detoxify cells by effluxing exogenous compounds. Here, we investigated the 'side population' phenotype based on efflux properties of ATP-bindi...
mammalian expression systems, due to their capacity in post-translational modification, are preferred systems for biopharmaceutical protein production. several recombinant protein systems have been introduced to the market, most of which are under clinical development. in spite of significant improvements such as cell line engineering, introducing novel expression methods, gene silencing and pr...
in the present study, an attempt was made to develop galactosylated albumin nanoparticles of cimetidine for treatment of acetaminophen induced hepatotoxicity. by developing the galactosylated nanoparticulated delivery of cimetidine the required action of drug at the target site i.e at liver can be provided. the advantage of targeting helps to reduce the systemic side effects which may be occur ...
23 We describe the occurrence of blaVIM-2 in 10 carbapenem-resistant Pseudomonas monteilii 24 strains isolated from different clinical samples in our hospital in Northern Spain. All the 25 blaVIM-2-harbouring P. monteilii isolates possessed a class 1 integron, with the cassette array 26 [intI1_blaVIM-2_aac(6’)-Ib_qacE1_sul1]. Our results show the emergence of VIM-227 producing multidrug-resist...
Custom genome editing has become an essential element of molecular biology. In particular, the generation of fusion constructs with epitope tags or fluorescent proteins at the genomic locus facilitates the analysis of protein expression, localization, and interaction partners at physiologic levels. Following up on our initial publication, we now describe a considerably simplified, more efficien...
Escherichia coli INS33 was isolated from the urinary tract of an infected patient. It was resistant to ampicillin, chloramphenicol, spectinomycin, streptomycin, sulfafurazole, tetracycline and trimethoprim. PCR screening revealed the presence of a class 1 integron that harboured two new gene cassettes, designated dfrA17 and aadA5. The new dfrA17 cassette was 91% identical to the known dfrA7 cas...
N-methyl-D-aspartate receptors (NMDARs) are Ca(2+)-permeable glutamate-gated ion channels whose physiological properties in neurons are modulated by protein kinase C (PKC). The present study was undertaken to determine the role in PKC-induced potentiation of the NR1 and NR2A C-terminal tails, which serve as targets of PKC phosphorylation [Tingley, W. G., Ehlers, M. D., Kameyama, K., Doherty, C....
The ability to produce embryonic stem (ES) cell lines containing different yeast artificial chromosomes (YACs) integrated into the same location in the genome provides a system for comparing the bio-logical effects of YAC transgenes without the confounding influences of integration site and copy number. A targeting system was developed for the directed integration of circular YACs into mouse ES...
Site-specific recombinases (SSRs) are valuable tools for manipulating genomes. In Drosophila, thousands of transgenic insertions carrying SSR recognition sites have been distributed throughout the genome by several large-scale projects. Here we describe a method with the potential to use these insertions to make custom alterations to the Drosophila genome in vivo. Specifically, by employing rec...
