Cochlear hair cells of the inner ear are mechanosensory transducers critical for sound reception in mammals. A mouse with a specific expression of Cre recombinase activity in hair cells is essential for hair cell-specific gene targeting. Here we report a transgenic mouse in which Cre activity is detected in inner hair cells, not in supporting cells, in the(More)
Soil sodium, while toxic to most plants at high concentrations, can be beneficial at low concentrations, particularly when potassium is limiting. However, little is known about Na(+) uptake in this 'high-affinity' range. New information is provided here with an insight into the transport characteristics, mechanism, and ecological significance of this(More)
Neuroglobin (NGB) is a characterized heme globin that is widely expressed in the vertebrate central and peripheral nervous system as well as retina and endocrine tissues. However, to date, it is not determined whether functional NGB is expressed in cells of glia origin. In this study, we aimed to explore the detailed expression of NGB in a rat astrocytoma(More)
Smu1 is an evolutionarily conserved gene that encodes a member of the WD40-repeat protein family. Disruption of Smu1 function leads to multiple cellular defects including chromosomal instability, aberrant DNA replication and alternative RNA splicing events. In this paper, we show that Smu1 is a chromatin-bound protein that functions as a negative regulator(More)
Drug-resistance and imbalance of apoptotic regulation limit chemotherapy clinical application for the human hepatocellular carcinoma (HCC) treatment. The reactivation of p53 is an attractive therapeutic strategy in cancer with disrupted-p53 function. Nutlin-3, a MDM2 antagonist, has antitumor activity in various cancers. The post-translational modifications(More)
We made a transgenic mouse that expresses Cre recombinase activity in inner ear hair cells by using a modified bacterial artificial chromosome containing Prestin. Cre recombinase activity was restricted to inner and outer hair cells, a subset of vestibular hair cells, spiral and vestibular ganglia in the inner ear, and a subset of cells in the testis,(More)
Secondary pneumonia due to Staphylococcus aureus (S. aureus) causes significant morbidity and mortality. The aim of the research was designed a novel DNA vaccine encoding the Mycobacterium tuberculosis secreted antigen Ag85A fused with the influenza A virus (IAV) HA2 protein to provide protection against both influenza and secondary infection with S.(More)
New approaches to improve the traditional gene carriers are still required. Here we explore Fe(3)O(4) modified with degradable polymers that enhances gene delivery and target delivery using permanent magnetic field. Two magnetic Fe(3)O(4) nanoparticles coated with chitosan (CTS) and polyethylene glycol (PEG) were synthesized by means of controlled chemical(More)
Oxaliplatin (OXP) was reported to show low anti-tumor activity when used alone and to display side effects; this low activity was attributed to high partitioning to erythrocytes and low accumulation in tumors. Thermosensitive liposomes (TSL) were considered able to specifically deliver drugs to heated tumors and to resolve the OXP distribution problem.(More)
Mature mouse beta defensin 2 (mBD2) is a small cationic peptide with antimicrobial activity. Here we established a prokaryotic expression vector containing the cDNA of mature mBD2 fused with thioredoxin (TrxA), pET32a-mBD2. The vector was transformed into Escherichia Coli (E. coli) Rosseta-gami (2) for expression fusion protein. Under the optimization of(More)
