Mutations in GJB2 are the most common molecular defects responsible for autosomal recessive nonsyndromic hearing impairment (NSHI). The mutation spectra of this gene vary among different ethnic groups. In order to understand the spectrum and frequency of GJB2 mutations in the Chinese population, the coding region of the GJB2 gene from 2063 unrelated(More)
Every year, 30,000 babies are born with congenital hearing impairment in China. The molecular etiology of hearing impairment in the Chinese population has not been investigated thoroughly. To provide appropriate genetic testing and counseling to families, we performed a comprehensive investigation of the molecular etiology of nonsyndromic deafness in two(More)
Nasopharyngeal cancer (NPC) is an endemic type of head and neck cancer with a high rate of cervical lymph node metastasis. Metastasis is the major cause of death in NPC patients. Increasing evidence indicates that exosomes play a pivotal role in promoting cancer metastasis by enhancing angiogenesis and ECM degradation. Matrix metalloproteinase 13 is an(More)
BACKGROUND FGF receptor (FGFR) family can be activated by FGFs and play important roles in regulating cell growth, differentiation, migration and angiogenesis. Recent studies suggested that FGFR4 could regulate several processes including tumor progression. Nasopharyngeal carcinoma (NPC) is a malignancy with a high occurrence in Southeast Asia and Southern(More)
OBJECTIVE HS1-associated protein X-1 (HAX-1) is a multifunctional protein that has been highlighted as an important marker in many types of cancers. However, little is known about the role of HAX-1 in laryngeal carcinoma. The purpose of the present study is to explore HAX-1 expression status and its associations with clinicopathologic features and survival(More)
Mesenchymal stem cells (MSCs), which are capable of differentiating into multiple cell types, are reported to exert multiple effects on tumor development. However, the relationship between MSCs and nasopharyngeal carcinoma (NPC) cells remains unclear. Exosomes are small membrane vesicles that can be released by several cell types, including MSCs. Exosomes,(More)
HS1-associated protein X-1 (HAX-1) is an important marker in many types of cancers and contributes to cancer progression and metastasis. We examined the expression of HAX-1 in nasopharyngeal carcinoma (NPC) and experimentally manipulated its expression. We observed that HAX-1 expression is elevated in NPC and is correlated with lymph node metastasis, M(More)
The extended use of doxorubicin (DOX) could be limited because of the emergence of drug resistance associated with its treatment. To reverse the drug resistance, two thiol-modified peptide sequences HAIYPRHGGC and THRPPMWSPVWPGGC were, respectively, conjugated to DOXO-EMCH, forming a maleimide bridge in this study (i.e., T10-DOX and T15-DOX). The structures(More)
SOX4, which belongs to the sex-determining region Y-related high-mobility group (SRY) box family, plays a critical role in embryonic development, cell fate decision, differentiation, and tumor development. Nasopharyngeal carcinoma (NPC) is one of the most common cancers in China and Southeast Asia. However, the molecular mechanisms of this disease remain(More)
Eg5 is identified as a microtubule-dependent motor protein and has been suggested to play important role in cancer development. The aim of this study was to detect the expression of Eg5 and its clinicopathological characteristics in patients with laryngeal squamous cell carcinoma. One-step quantitative reverse transcription-polymerase chain reaction (qPCR)(More)
