Salicylate, a common drug frequently used long term in the clinic, is well known for causing reversible hearing loss and tinnitus. Our previous study, however, demonstrated that chronic administration of salicylate progressively raised the amplitude of distortion product of otoacoustic emissions (DPOAEs), which are mainly caused by (outer hair cell) OHC(More)
OBJECTIVE Analysis of the correlation between telomerase and the expression of its related proteins may provide insight into the molecular mechanism of nasopharyngeal carcinogenesis. We investigated the effect of short hair pin ribonucleic acid (RNA) specific for human telomerase reverse transcriptase messenger RNA on the expression of the proteins c-myc(More)
TERT is the main functional unit of telomerase, which maintains telomere length and chromosome structure stability. TERT has been shown to act as a key factor in various biological processes, such as cell proliferation, via uncharacter-ized mechanisms. We transfected HEp-2 laryngeal carcinoma cells with a TERT overexpressing adenovirus (Ad-TERT) and TERT(More)
Global DNA hypomethylation, in particular that of the gene promoter sequence in gene hypermethylation, is a well-known characteristic of human cancer. Subtelomeres are enriched CpG islands; methylation is believed to be a potential epigenetic regulator. However, regulation on the telomere length remains largely unknown. To demonstrate this correlation, four(More)
Auditory transduction in the cochlear is subject to modulate higher auditory centers in the brain via the efferent systems, which provide protection against damage caused by excessive excitation during auditory over stimulation. GABA is a proven inhibitory neurotransmitter in the efferent systems in mammalian cochlear. KCC2 is a neuron-specific potassium(More)
OBJECTIVE To develop an RNA-interference (RNAi) approach involving the hitting of multiple targets by a recombinant plasmid and evaluate its antitumor effect on laryngeal squamous carcinoma in vitro and in vivo. MATERIALS AND METHODS A plasmid containing 3 different short hairpin RNA (shRNA) segments termed pEGFPshVEGF-shTERT-shBcl-xl was constructed.(More)
The transcription factor, Forkhead Box M1 (FoxM1), has a specific expression pattern during the cell cycle. It also plays an important role in cellular developmental pathways and in the maintenance of homeostasis between cell proliferation and apoptosis. However, the precise role and molecular mechanisms associated with FoxM1 in laryngeal squamous carcinoma(More)
BACKGROUND & OBJECTIVE RNA interference (RNAi) is triggered by the presence of double-stranded RNA (dsRNA) in the cell and results in rapid destruction and post-transcriptional gene silencing of target mRNA. The roles of RNAi in gene function and antiviral therapy have been reported, but its effect on human telomerase reverse transcriptase (hTERT) gene,(More)
OBJECTIVE To establish the activation of NF-kappaB in middle ear cholesteatoma, discuss the relationship of NF-kappaB and the gene expression of IL-6 and explore the pathogenesis of middle ear cholesteatoma. METHODS Ten cases of cholesteatoma and 6 cases of normal external meatal skin were obtained from middle ear surgery. The NF-kappaB DNA binding(More)
Interleukin-10 (IL-10) has an important anti-inflammatory and immunoregulatory function, and its expression is negatively correlated with the development and severity of allergic rhinitis (AR). However, the in vivo effects of exogenous IL-10 on AR have not been studied and the mechanisms underlying the effects of IL-10 have not been fully understood. Here,(More)
