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 In our previous work, we constructed short hairpin RNA (shRNA) expression plasmids that targeted human telomerase reverse transcriptase (hTERT) messenger RNA, and we demonstrated that these vectors could inhibit the growth of cancer cells by 76.5% in vivo. In order to maximize the efficiency and versatility of the vector-based siRNA approach,(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)
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)
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)
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)
In most human malignancies, telomere homeostasis is maintained by the reactivation of telomerase. While inhibiting telomerase provides a novel approach to the treatment of many cancers, telomere maintenance can occur in the absence of telomerase activity by the alternative lengthening of telomeres (ALT) mechanism. Therefore, it must be determined if(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)
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)
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)
