Currently, the main approach to nasopharyngeal carcinoma (NPC) treatment is radiotherapy (RT), but for many NPC patients, RT is not effective. Increasing RT sensitivity of NPC cells would provide a significant treatment advance for NPC patients. While γ-secretase inhibitors (GSIs) have gained recent attention as novel anticancer drugs, the mechanism of(More)
Previous case–control studies assessing the association between microsomal epoxide hydrolase 1 (EPHX1) T113C and susceptibility to lung cancer reported conflicting results. Thus, a systemic review and meta-analysis of published studies were performed to assess the possible association. PubMed and Embase databases were searched for all eligible studies. The(More)
Allergic rhinitis (AR) is a common chronic inflammatory condition of the nasal mucosal tissue. The interleukin-13 (IL-13) signaling pathway is of great importance in the pathogenesis of AR. However, how the signaling molecules in this pathway are regulated, particularly through microRNAs (miRNAs), remains unclear. In the present study, we investigated the(More)
The development of presbycusis, or age-related hearing loss, is determined by a combination of genetic and environmental factors. The auditory periphery exhibits a progressive bilateral, symmetrical reduction of auditory sensitivity to sound from high to low frequencies. The central auditory nervous system shows symptoms of decline in age-related cognitive(More)
MicroRNA-143 (miR-143) was found to be downregulated in allergic rhinitis, and bioinformatics analysis predicted that IL-13Rα1 was a target gene of miR-143. To understand the molecular mechanisms of miR-143 involved in the pathogenesis of allergic inflammation, recombinant miR-143 plasmid vectors were constructed, and human mast cell-1(HMC-1) cells which(More)
OBJECTIVE To analyze the roles of chemokines and their receptors in the pathogenesis of allergic rhinitis by observing the complementary DNA (cDNA) expression of the chemokines and their receptors in the nasal mucosa of patients with and without allergic rhinitis, using gene chips. METHODS The total RNAs were isolated from the nasal mucosa of 20 allergic(More)
Ototoxicity induced by aminoglycoside antibiotics appears to occur both in hair cells (HCs) and the cochlear nerves that innervate them. Although HC loss can be easily quantified, neuronal lesions are difficult to quantify because two types of afferent dendrites and two types of efferent axons are tangled beneath the hair cells. In the present study,(More)
Plasminogen activator inhibitor-1 (PAI-1) is the most effective protease inhibitor in the fibrinolysis system, and plays an important role in the remodeling of the extracellular matrix. We therefore explored whether PAI-1 is involved in the change of lung structure with increasing age. PAI-1 gene knockout mice and wild-type mice were sacrificed at age 3(More)
OBJECTIVE AND DESIGN To determine whether RBL-2H3 cells have endogenous substance P (SP) expression under immunoglobulin E (IgE)-activated and inactivated conditions, and to ascertain the function of endogenous SP in the antigen-induced degranulation of RBL-2H3 cells. MATERIALS AND METHODS SP mRNA and protein expression in both inactivated and(More)
Latent membrane protein 2A (LMP2A) is found to play a key role in the development of nasopharyngeal carcinoma (NPC). However, the role of LMP2A silencing in the inhibition of cell growth of NPC has not been clarified. In this study, we inhibited LMP2A gene expression by lentivirus-mediated RNAi, to explore the effects of LMP2A silencing on the growth of NPC(More)
