Nasopharyngeal carcinoma is one of the most common types of malignant tumor in Southern China and Southeast Asia, and its etiology is closely associated with Epstein-Barr virus (EBV) infection. Non-keratinizing carcinoma accounts for >95% of all nasopharyngeal carcinoma cases. In addition, metastatic nasopharyngeal carcinoma from other locations in the body is extremely rare. This study reports...

Recent development of cutting edge research found that long noncoding RNAs (lncRNAs) plays important roles in carcinogenesis and progression. In Southeast Asia and North Africa, nasopharyngeal carcinoma (NPC) is the most common aggressive squamous cell carcinoma. Nasopharyngeal carcinoma is most frequently occurring in males. However, nasopharyngeal carcinoma is caused by a combination of sever...

INTRODUCTION Nasopharyngeal carcinoma is the most common cancer originating from the nasopharynx. OBJECTIVE To study the mechanisms of nasopharyngeal carcinoma, we analyzed GSE12452 microarray data. METHODS GSE12452 was downloaded from the Gene Expression Omnibus database and included 31 nasopharyngeal carcinoma samples and 10 normal nasopharyngeal tissue samples. The differentially express...

BACKGROUND Several studies have suggested that claudin proteins, which are the main components of tight junction structures, are related to the regulation of cell polarity and cell differentiation. METHOD To explore the expression profiles of the tight junction proteins claudin-2, - 5, - 8 and - 9 in nasopharyngeal carcinoma, IHC (immunohistochemical analysis), Western blot and real-time PCR ...

BACKGROUND No studies have examined the relationship between COX-2 8473T>C polymorphism and the risk of nasopharyngeal carcinoma in Chinese population. MATERIAL AND METHODS 296 patients with nasopharyngeal carcinoma and 300 age and gender-matched healthy controls recruited were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Cancer risk associated w...

BACKGROUND To analyze the mortality distribution of nasopharyngeal carcinoma in China from 1991 to 2013, to predict the mortality in the ensuing five years, and to provide evidence for prevention and treatment of nasopharyngeal carcinoma. MATERIALS AND METHODS Mortality data for Nasopharyngeal Carcinoma in China from 1991 to 2013 were used to describe its epidemiological characteristics, such...

Radiotherapy is the primary treatment for nasopharyngeal carcinoma while radioresistance can hinder efficient treatment. To explore the role of annexin A1 and its potential mechanisms in radioresistance of nasopharyngeal carcinoma, human nasopharyngeal carcinoma cell line CNE2-sh annexin A1 (knockdown of annexin A1) and the control cell line CNE2-pLKO.1 were constituted and CNE2-sh annexin A1 x...

This study aimed to assess independent effects of EBV and cigarette smoking on nasopharyngeal carcinoma, which have never been assessed in long-term follow-up studies. A cohort of 9,622 men was enrolled from 1984 to 1986. Blood samples collected at study entry were tested for antibodies against EBV antigens (anti-EBV) viral capsid antigen immunoglobulin A and DNase. The cigarette smoking habit ...

Objective: Our purpose was to investigate the expression of Testin gene and its possible relationship with the clinic pathological features of human nasopharyngeal carcinoma. Methods: The expression of Testin in nasopharyngeal carcinoma tissues were detected by immunohistochemical methods, semi-quantitative reverse transcription polymerase chain reaction and western blot. The correlations of Te...

Southern China experiences larger extent of total cancer pathologies, of which nasopharyngeal carcinoma has the highest incidence under otorhinolaryngeal malignant carcinomas. Risk factor of nasopharyngeal carcinoma varies from hereditary causes to virus infection, among which Epstein-Barr virus (EBV) infection is the mostly investigated. The study into mechanism of EBV in occurrence, developme...
